You can just use a can of air once a month, and then you will never get any build-up. If the fans and heatsink have never been cleaned and are already clogged, you will need to disassemble the entire machine and remove the fans, and blow them out with air. The best practice is to never let it get like that.
Um, yeah - why wouldn't you do this regularly, man? Not having a go at you personally but so many people think a gaming laptop is kind of like an iPad in terms of care and servicing - in other words, zero.
I'm not at all defending Dell, because they aren't very customer focused. But, I have NEVER seen a laptop with so easily accessible fans EVER! So there's absolutely no excuse to not clean them. However, that might not be the only thing that needs to be done with it. I would say people that buy this kind of electronics and people who buy Apple are just as ignorant. I can tell you that there is other laptops that are SO MUCH WORSE when it comes to being able to change the thermal compound. I recently disassembled a Samsung from the 700G Series that is from around 2008, it has a dedicated graphics card with the MXM form factor and I needed to disassemble it completely, and it's a real pain in the a§§ to do, and then assemble it again. I felt that I might need to point out to some users that, if you use a laptop in the bed. You are most likely suffocating the computer if you don't use a small table or cooling pad to lift it up from the cover. I had a friend that worked as a IT technician that pointed that out to me, and he did it himself after the fact that he pointed it out to me... I've seen on Electronics Repair School that he simply uses alcohol on the component he suspect is damaged and wait for the alcohol to get vaporized instead of using a FLIR. A poor mans solution that I've never tested myself, and I would suggest anyone to be careful with that.
@@sykoteddy it was the standard way before Thermal imaging got anywhere near affordable, it works very well as the alcohole evaporates first from hot components, but yes a warning about applying alohole to somethn extremely hot or a flame might be in order, and if ur using a gas soldering iron be a bit careful just... ..alcohole usually dont ignite so easily when used in electronics (if u work with electronics u likely use pure IPA dayly for example ... just dont light a smoke while cleaning and ur okay)
This is why I recommend temp apps to people when they get a brand new computer and note what's the base line and the highest temp it goes to. This way if for some reason when you start your computer and it's 10 degrees higher than usual and it's like this consistently, it's time to clean out your fans. I dumbed it down to this cause not everyone is tech savvy. I got an Alienware myself and when I noticed it ran close to 60C when I was idle when it's temps were usually around 45C, I knew I had forgotten to clean my fans. I usually clean them every 3 to 6 months. Another good video. Only recently subbed, I don't understand it all but I get the gist of it. It's digestible info.

I went through 4 motherboard on this model had a lot of dead cpu when under warranty.. happened again out of warranty bought a repaired motherboard on ebay and never had any issue for the past 3 years..
Wow crazy! 😮 This customer said that had it replaced in 2021, but the laptop is now more than 7 years old. I think it had a pretty good run, considering.
@dellpartspeople i dont know what the tech did on the motherboard maybe better mosfet (i dont know if it help prevent the voltage short to cpu/gpu) but it last way longer than all the other dell provided
Instead of removing the power stage to find the short, you could remove the inductors, one at a time. That will isolate the power stage from the other ones, and you can ohm out the power stage.
Nah man. I’ve used my laptop in bed for years. Over blankets and other covers. It’s has never been this bad. The person who owns it it’s just a nasty person

I like the fact that you take your time when working. (I'm not specifically referring to this video, but the one when someone attempted to replace the battery and ripped off a component). A lot of repair shops don't spend much time fixing laptops. If the problem isn't obvious, they often declare it unrepairable and move on, still charging the customer a lot. In the case where the CPU is fried by 20V, is replacing just the CPU an option? I know it's quite difficult due to the reballing process and the risk of accidentally desoldering the small components, like the microscopic capacitors and resistors, around it.
the boards that don't end up being fixable, do you keep them as parts boards, or is that not feasible due to the possibility of not knowing what all got damaged?
And that is why my laptop is a business machine. It's fast enough, and I can get it apart to clean it in a trice because it's designed to be serviceable. And it's rather pretty. And I have HWInfo telling me what my temps are at all times on my taskbar.

How do you clean these things out if accessing the fans requires you to remove the motherboard? Are Alienware owners just expected to fully remove their motherboard, clean out the fans and repaste everything every half year or so?
You can just use a can of air once a month, and then you will never get any build-up. If the fans and heatsink have never been cleaned and are already clogged, you will need to disassemble the entire machine and remove the fans, and blow them out with air. The best practice is to never let it get like that.
@dellpartspeople I was under the impression that blowing compressed air into the fans was not good because 1) it would just blow the dust deeper into the fans and heat sink and 2) the fans could be damaged via the air causing the fan baldes to spin in an uncontrolled manner.
My place has very little dust inside. I usually clean my house every week or two to prevent it. I'm amazed how much dust is collected inside computers and laptops and I'm fortunate my electronics are not caked in dust. It's disappointing you didn't get to save the laptop, but it is not your fault. I wish people would take better care with their stuff like me.
Discovered your channel recently, love it, thanks. Is the CPU non-replaceable/wouldn't likely fix any other issues, hence only fix is whole motherboard replacement?
you can replace the cpu, but the issue is finding a good one and second issue is you need a "heatplate" and after cpu is swapped you sometimes need to add or reposition a few other smd components for it to function so it.s a bit more complicated procedure and more expensive
@@petricagigi-ev4zd Thanks, what's a heatplate/for? Something to warm the whole board so the cpu can be desoldered and replacement soldered in? I'm assuming it's a surface mount/ball type cpu? And yes, I know that's an issue/difficult, especially re-balling a chip (have seen it done on Rossmann's channel). Thanks again.
Once you said you have a trick to find a shorted mosfet I thought nice, he's going to short the coils and inject voltage at the same time to make the dead mosfet send all the current to ground... so close! xD
@dellpartspeople Just from around 5:45 I can tell you its best to replace the far left and far right and middle from the right to left ones are the bad ones. Because the far left and far right ones have a chunk of the chip missing. For the far right one its hard to read the stuff when the chip just one left is perfectly readable. For the far left one at around 5:41 you can see where there's a dip right where part of the chip info is just missing. As for the one middle from right to left at about 5:43 it has a rounded edge instead of a flat edge. The only way for a chip to have those issues is if it gets extremely hot, and the only way for a chip to get extremely hot like that is if the chip is or was faulty/shorted out/unusually high wattage to or through it. A dead give away of faulty chips is ones that aren't completely flat, or that have a sudden dip on it that's just there and isn't gradually led into a dip. If unsure you can always compare the chip to a known good one and tell if it's damaged. The quickest method is by just looking for being unable to read the writing on the chip, and looking for sudden and random dips that are rough/uneven
A device for truly enthusiasts - who know what good and dangerous temperatures are, know which temp measuring apps are decent and which are not and just show random numbers, etc. All this because manufacturer decided that if CPU is not overheating (well, it has a fan...) then VRM is not overheating either and there is no need for a temp sensor to shut down the whole rig.
People don't realize the amount of current flowing through these devices. Let's do some quick back of the napkin calculations using Ohms law. Let's say VCC is 1.3v and say the TDP is 100W. That means at the maximum power usage your CPU is drawing 100W of power. That doesn't take into account boost which sometimes will draw more power than TDP briefly, and assumes 100% efficiency (which isn't realistic). Anyway, let's say for sake of discussion you are working around 100W with a Vcc of 1.3V. Since I = W/V we would have 100W / 1.3V which is about 77A!!!! That's a LOT of current! That's a super simplified version and doesn't take into account the processor speed or anything like that. Modern processors are power junkies! Great Video!
that would be a great unit to use for parts, I have a 17 R4 with a chipped corner because I accidentally knocked it off of a stand one time. Didn't do any damage except cosmetic, but I would love to replace the cover at some point. I've already had to replace the keyboard and fans, I'm gonna use it as long as I can.
Hi, have question, When CPU's ect are toast and techs have to swap out boards, what happens to problem with Win Keys? Do you sell them another key or use Transfer software to migrate everything to another board but that new board has to have a diff key or old one already? Lot of time and expense to do this?
The lack of any protection circuitry, such as "crowbar circuit", tvs, zener, mov's, proofs how much the manufacturer cares about quality and durability! An additional 2 USD in components, could've saved the CPU from being fried! However, when they produce 10 million devices like this, those 2 USD in components become 20 million USD of lost revenue. So it was deemed to expensive by the executives, who would rather invest some additional millions into their mansions and yachts! Regardless of this decisions being detrimental to the products quality or Alienwares branding!
What is the beat method of cleaning out the dust, lint, etc., from the inside of a laptop computer? I have used can air through the air vents in the past but I read that that is a bad way because it only just movies the dust, lint, etc., around. Should the laptop computer be opened up and then use canned air to remove the stuff? Also, how often should the cleaning be done? Thanks.
Valid question. Blaming the owner here, but having taken my Dell Workstation apart for a repasting I don't ever want to work on a f***** Dell again. My old HP Elitebook I can strip and clean in five minutes, that Dell was a plastic prying/cracking two hour ordeal.
@@Referee006 I also have Acer aspire 7, have it cleaned and thermal paste replaced by a local PC repair shop. It made a 10 degrees Celsius difference.
Occasionally, one should check the CPU and GPU temperatures via the software, especially under load. One should know the normal range for their machines. If you own something, you need to have minimal knowledge on maintenance in order to get the maximum value from your machines.
1:15 That amount of screws will drive me crazy. Why not get those "pen type" motorised screwdriver? Would save you lots of time and wrist, not to mention your sanity.
I have one, but I find that they do not have enough torque to start unscrewing the screw, so I end up having to manually start it anyway. They also are not that fast, at least not the one I have.
Surely its not impossible to put something between the VRM and the CPU that'll block voltages past a certain safety threshold? Is it not doable or is it again just Dell cheaping out?
Those mosfets aren’t overly expensive. He may have taken a known good one off a donor board as well , especially because he knew it was more than likely toast.
Are the workstations like the Dell Precision better built than the gaming laptops? It seems like failures are much less common among higher end workstation laptops. Any laptop is going to fail if there is inadequate cooling from dust building up, but it does feel like the Precision and similar laptops seem to last longer. They are more conservatively clocked and seem to be better built, despite also having high end CPUs and GPUs. It would follow the same trend of business laptops lasting longer than consumer laptops.
It’s also likely that the sort of person putting down money on a tool that makes them money, is probably going to take better care of their machine than many gamers.
These cassini machines all seem to go the same way. Those MOSFETs fail to the CPU and take the CPU out. Northridge fix has several videos showing the exact same thing. Makes me think whoever made those MOSFETs had a bad batch.
I also have a 2+1 blink code on a inspiron 3582 which points to a cpu failure, also the caps lock key light is stuck on. It was initially dead with a broken power jack and socket which I replaced and it successfully charged. I'm pretty sure it got fried due to a short but at least I'm using it to test and learn stuff.
I might understand the owner why they're fear about cleaning laptop. I have 2 dells, one is G3 which is i cleaned by my self. After unplugging the battery, i unplugged the fan to clean and plugged in again and replace thermal paste. After plugging the battery again, the laptop screen is not showing (i already delivered to the technician and he told my its my fault so the ram source is dead and might happen to the chip). And the 2nd one is dell Vostro, this time i give to the shop do the cleaning. After using a week, my Vostro laptop has a symptom of overheating, it usually restarted by itself. Now, i'm using mac mini (m1), and still using it for 4 years without any heat issue (using it from 2021).
basically used laptop will cost like cpu replacement + job payment. the only exception would be using an engineer cpu that was used in factory for testing, they cost two times less, the only problem is in finding a trusted seller, they are sold in China and ofc many sellers are scammers.
When it comes to laptops, even more so modern ones aren't known for their ease of disassembly, so I don't think it's fair to blame the user for neglect, I can get into them fine and I'm still kind of annoyed to do it unless the bottom comes right off with little to no clips.
You can just use a can of air once a month, and then you will never get any build-up. If the fans and heatsink have never been cleaned and are already clogged, you will need to disassemble the entire machine and remove the fans, and blow them out with air. The best practice is to never let it get like that.
Update, I talked to the customer, and he went ahead with the motherboard replacement. The CPU cannot be changed because it is part of the board. So, I now have the laptop up and running. The new motherboard cost $400, plus my labor, of course.
-Finding a reliable cpu (Intel won’t sell you one) -Procuring the tools and stencils and optimizing them to work properly (Rossmann has some videos where he does this) Not easy.
@@dellpartspeople nice to see this on old day was so much easy to change cpu or gpu this days is no option of this . and the new laptops this days have 1 ram slot other one is soldered ram
Even among repair techs, the tools to perform a BGA rework tend tombe bespoke for each CPU gen, and hard to come by, not to mention how extremely labor intensive it is (not necessarily difficult, but quite monotonous to scan through literal thousands of solder balls).
It is very impressive. You know the hardware. I have a Inspiron 1720 that has this kind of problem. Core2Duo. Removable nvid video carp. 256 MB of VRAM. I would to fix it for the sake of fixing.

Next time, short the vrm outputs and inject current. That will light up the shorted chip. Also, getting a better camera will boost your ability to gauge if a cpu or gpu or other chips like that is shot. You need better resolution and framerate is a big bonus. Even with the board powered normally or by injecting voltage in the vrm rails (0.8-1.7) After looking at a few good and dead cpus, you will know at a glance, next time.
How much does a motherboard normally run for one of these? Don't normally work on Dells, but Lenovo's, lol. I know I that when I had replace a motherboard in a Thinkpad T480, due to an aftermarket charger blowing up the MOSFETs, and processor, it was like $50 for the I7, $35 for the I5 motherboard(8th gen core architecture, the minimum to run win 11, lol) I used the I7 board, this was a "free" laptop that someone gave me.
you don't need the greatest technician that's ever lived, you need the "GOOCH COLLECTOR" with that amount of gooch, dirt, dust and grimes. Am surprised you didn't turned to a skeleton yet with that. 🤣, besides you got this the greatest DELL technician that's ever lived.
don't think it's entirely owner's neglect. I had exact same laptop and thermal pad not thick enough to touch the mosfets or not placed properly in factory. I was able to fix with K5-pro thermal pad-paste. had Precisions with way more dust running years without problem
They don't make it easy for an end user that wouldn't know how to open up the machine without breaking it to clean the fans. That's intentional. Let's assign the blame where it lies: the manufacturers. They could easily make the machines much more user serviceable but that would cut into future sales.
I remember once having a PC that was very noisy. When I opened it up there was a fist sized lump of nicotine infused brown dust. Looked like a hamster had died in it. I've seen some things...
I have a Dell L701x Xps17.. I need a subwoofer.. This laptop has(had) the best sound of any laptop i ever owned and now it sounds like it's farting from the sub.. I can't find one anywhere. (UK).
Sadly, The Number one killer is overheating, due to poor circulation of Air! The Older Gaming Laptop CPU/GPU are changeable? But lots of these quick built CPU were solder in first than built around it! A can of Blow Air come in 3-4 pack of CO2 air! Caution it can freeze -05' or lower? Hopefully he should found a replacement boards from 50 to 150+ USD? And buy a Good Gaming Pad with 4-6 Fans and once a month to shut down Laptop and blow the fans and intake/exhaust on Laptop until you feel AIR coming out?
I felt your comment about the board being the "best design ever" as I helped a friend replace a failing, noisy GPU fan in his AlienWare laptop. When I looked up the service manual, realized it had to be fully disassembled to replace the fans, I advised my friend to buy both fans because the other one was likely not far behind and I had zero interest in taking it apart again. What's that USBC power supply you're using? I want something like that with a display and robust design. Those inline testers you can get on Amazon are typically poor quality, have the output cable permanently attached, and are not trustworthy that they are wired properly for high current.
I suddenly have an urge to clean out the heatsinks on my Alienware laptop. 😬

Or, if fixing desktop replacing the power cord to the back of the power supply, or turning the switch on the p/s (if it has one) to on... :)
we need a lot of vedios like this one sir , really its intersting and we love yours longs vedios with the explications of this problems .
Great job! You found the problem, but of course the issue being, is it worth the cost of repair to the customer? Thank you.
@dellpartspeople Just from around 5:45 I can tell you its best to replace the far left and far right and middle from the right to left ones are the bad ones. Because the far left and far right ones have a chunk of the chip missing. For the far right one its hard to read the stuff when the chip just one left is perfectly readable. For the far left one at around 5:41 you can see where there's a dip right where part of the chip info is just missing. As for the one middle from right to left at about 5:43 it has a rounded edge instead of a flat edge. The only way for a chip to have those issues is if it gets extremely hot, and the only way for a chip to get extremely hot like that is if the chip is or was faulty/shorted out/unusually high wattage to or through it. A dead give away of faulty chips is ones that aren't completely flat, or that have a sudden dip on it that's just there and isn't gradually led into a dip. If unsure you can always compare the chip to a known good one and tell if it's damaged. The quickest method is by just looking for being unable to read the writing on the chip, and looking for sudden and random dips that are rough/uneven
A device for truly enthusiasts - who know what good and dangerous temperatures are, know which temp measuring apps are decent and which are not and just show random numbers, etc. All this because manufacturer decided that if CPU is not overheating (well, it has a fan...) then VRM is not overheating either and there is no need for a temp sensor to shut down the whole rig.
Great Vid. I have a 15 R2 and taking a vacuum to it real soon!
People don't realize the amount of current flowing through these devices. Let's do some quick back of the napkin calculations using Ohms law. Let's say VCC is 1.3v and say the TDP is 100W. That means at the maximum power usage your CPU is drawing 100W of power. That doesn't take into account boost which sometimes will draw more power than TDP briefly, and assumes 100% efficiency (which isn't realistic). Anyway, let's say for sake of discussion you are working around 100W with a Vcc of 1.3V. Since I = W/V we would have 100W / 1.3V which is about 77A!!!! That's a LOT of current! That's a super simplified version and doesn't take into account the processor speed or anything like that. Modern processors are power junkies! Great Video!
There is a reason that mainframe computer equipment pressurizes the box through a replaceable air filter.
thank you for sharing motherboard repairs
that would be a great unit to use for parts, I have a 17 R4 with a chipped corner because I accidentally knocked it off of a stand one time. Didn't do any damage except cosmetic, but I would love to replace the cover at some point. I've already had to replace the keyboard and fans, I'm gonna use it as long as I can.
Hi, have question, When CPU's ect are toast and techs have to swap out boards, what happens to problem with Win Keys? Do you sell them another key or use Transfer software to migrate everything to another board but that new board has to have a diff key or old one already? Lot of time and expense to do this?
If replaced with like mbd, should be no problem with the key.
The lack of any protection circuitry, such as "crowbar circuit", tvs, zener, mov's, proofs how much the manufacturer cares about quality and durability!
An additional 2 USD in components, could've saved the CPU from being fried!
However, when they produce 10 million devices like this, those 2 USD in components become 20 million USD of lost revenue. So it was deemed to expensive by the executives, who would rather invest some additional millions into their mansions and yachts! Regardless of this decisions being detrimental to the products quality or Alienwares branding!
Hopefully in the future there will be a breakthrough in semiconductors that allow MOSFETs and Diodes to fail open circuit.
Thank you for making these videos!!!!!!!!!!
11 min 56 That looks like a complicated chip. It has many pins. It isn't just a transistor?
11:56
If you write timestamps like this, it becomes a link that automatically puts the video to that time.
@-sturmfalke- I don't write like that so that youtube does not delete my comments. I am afraid of youtube.
Why do you offering to replace entire motherboard instead of replacing burned cpu?
Was the CPU embedded?
i have never seen a cip soldering po urely,in i see 2 pins of that chip solderet tugether in pure shortcut im i wrong
This video gives makes me want to open up my computer and give everything a good cleaning.
What is the beat method of cleaning out the dust, lint, etc., from the inside of a laptop computer? I have used can air through the air vents in the past but I read that that is a bad way because it only just movies the dust, lint, etc., around. Should the laptop computer be opened up and then use canned air to remove the stuff? Also, how often should the cleaning be done? Thanks.
Valid question. Blaming the owner here, but having taken my Dell Workstation apart for a repasting I don't ever want to work on a f***** Dell again. My old HP Elitebook I can strip and clean in five minutes, that Dell was a plastic prying/cracking two hour ordeal.
Thanks for your reply. I have an Acer laptop and I have had it for several years, and so it must be pretty dusty to awhile.
@@Referee006 I also have Acer aspire 7, have it cleaned and thermal paste replaced by a local PC repair shop. It made a 10 degrees Celsius difference.
Occasionally, one should check the CPU and GPU temperatures via the software, especially under load. One should know the normal range for their machines. If you own something, you need to have minimal knowledge on maintenance in order to get the maximum value from your machines.
They they blame it on the manufacturer... I've seen it many times.
1:15
That amount of screws will drive me crazy. Why not get those "pen type" motorised screwdriver? Would save you lots of time and wrist, not to mention your sanity.
I have one, but I find that they do not have enough torque to start unscrewing the screw, so I end up having to manually start it anyway. They also are not that fast, at least not the one I have.
Ratchets are good.
Surely its not impossible to put something between the VRM and the CPU that'll block voltages past a certain safety threshold? Is it not doable or is it again just Dell cheaping out?
Two questions
#1 if chip replacement didnt work, do you put back the old broken chip?
#2 how much does the chip cost?
Those mosfets aren’t overly expensive. He may have taken a known good one off a donor board as well , especially because he knew it was more than likely toast.
Are the workstations like the Dell Precision better built than the gaming laptops? It seems like failures are much less common among higher end workstation laptops.
Any laptop is going to fail if there is inadequate cooling from dust building up, but it does feel like the Precision and similar laptops seem to last longer. They are more conservatively clocked and seem to be better built, despite also having high end CPUs and GPUs.
It would follow the same trend of business laptops lasting longer than consumer laptops.
It’s also likely that the sort of person putting down money on a tool that makes them money, is probably going to take better care of their machine than many gamers.
Is that CPU obsolete? Can't be swapped with crossed fingers?
These cassini machines all seem to go the same way. Those MOSFETs fail to the CPU and take the CPU out. Northridge fix has several videos showing the exact same thing. Makes me think whoever made those MOSFETs had a bad batch.
That amount of dust is many times caused, in my experience, by those people who never turn their PC off.
Yep, 24/7 is for desktop machines laptops just aren't suitable for it
Well it's off now and probably permanently.
Why can't we have cpu's that can handle high voltage?
I also have a 2+1 blink code on a inspiron 3582 which points to a cpu failure, also the caps lock key light is stuck on. It was initially dead with a broken power jack and socket which I replaced and it successfully charged. I'm pretty sure it got fried due to a short but at least I'm using it to test and learn stuff.
This is one of the reasons that I made risers for all of my laptops :) .
You should make more consecutive videos about repair ❤
I might understand the owner why they're fear about cleaning laptop. I have 2 dells, one is G3 which is i cleaned by my self. After unplugging the battery, i unplugged the fan to clean and plugged in again and replace thermal paste. After plugging the battery again, the laptop screen is not showing (i already delivered to the technician and he told my its my fault so the ram source is dead and might happen to the chip). And the 2nd one is dell Vostro, this time i give to the shop do the cleaning. After using a week, my Vostro laptop has a symptom of overheating, it usually restarted by itself. Now, i'm using mac mini (m1), and still using it for 4 years without any heat issue (using it from 2021).
Stupid question, but is a CPU replacement not possible? Or is it like waaay too many solder points?
basically used laptop will cost like cpu replacement + job payment. the only exception would be using an engineer cpu that was used in factory for testing, they cost two times less, the only problem is in finding a trusted seller, they are sold in China and ofc many sellers are scammers.
When it comes to laptops, even more so modern ones aren't known for their ease of disassembly, so I don't think it's fair to blame the user for neglect, I can get into them fine and I'm still kind of annoyed to do it unless the bottom comes right off with little to no clips.
It is the dust that makes a computer over-heat and not dried thermal paste ...
Why can't you just replace the processor? why the whole MB?
no need to inject volatge just lift the otherside of each cpu coil just to know which mosfet is bad-
My laptop only work fan spinning when charging what to do bro tell me please name:dell latitude 5420😢
How do you keep the fans and heat sinks clean?
You can just use a can of air once a month, and then you will never get any build-up. If the fans and heatsink have never been cleaned and are already clogged, you will need to disassemble the entire machine and remove the fans, and blow them out with air. The best practice is to never let it get like that.
if the cpu is only dead why not change it for new one if is the price is not to high
That's the problem finding it and the price
Update, I talked to the customer, and he went ahead with the motherboard replacement. The CPU cannot be changed because it is part of the board. So, I now have the laptop up and running. The new motherboard cost $400, plus my labor, of course.
-Finding a reliable cpu (Intel won’t sell you one)
-Procuring the tools and stencils and optimizing them to work properly (Rossmann has some videos where he does this)
Not easy.
@@dellpartspeople nice to see this on old day was so much easy to change cpu or gpu this days is no option of this . and the new laptops this days have 1 ram slot other one is soldered ram
Even among repair techs, the tools to perform a BGA rework tend tombe bespoke for each CPU gen, and hard to come by, not to mention how extremely labor intensive it is (not necessarily difficult, but quite monotonous to scan through literal thousands of solder balls).
The kind of stuff I want to learn
Mee too!
It is very impressive. You know the hardware.
I have a Inspiron 1720 that has this kind of problem. Core2Duo. Removable nvid video carp. 256 MB of VRAM.
I would to fix it for the sake of fixing.
Next time, short the vrm outputs and inject current. That will light up the shorted chip.
Also, getting a better camera will boost your ability to gauge if a cpu or gpu or other chips like that is shot.
You need better resolution and framerate is a big bonus.
Even with the board powered normally or by injecting voltage in the vrm rails (0.8-1.7)
After looking at a few good and dead cpus, you will know at a glance, next time.
Framerate as in 60? y/n?
I take the back off at least once a year and clean the fans...
How much does a motherboard normally run for one of these? Don't normally work on Dells, but Lenovo's, lol. I know I that when I had replace a motherboard in a Thinkpad T480, due to an aftermarket charger blowing up the MOSFETs, and processor, it was like $50 for the I7, $35 for the I5 motherboard(8th gen core architecture, the minimum to run win 11, lol) I used the I7 board, this was a "free" laptop that someone gave me.
you don't need the greatest technician that's ever lived, you need the "GOOCH COLLECTOR" with that amount of gooch, dirt, dust and grimes. Am surprised you didn't turned to a skeleton yet with that. 🤣, besides you got this the greatest DELL technician that's ever lived.
wow, u know about the greatest technician that ever lived
don't think it's entirely owner's neglect. I had exact same laptop and thermal pad not thick enough to touch the mosfets or not placed properly in factory. I was able to fix with K5-pro thermal pad-paste. had Precisions with way more dust running years without problem
At this point, the laptop is 7 years old, and there was little to no airflow. I think the MOSFETs held on as long as they could.
what a pity plug in ac to many times didn't help cpu
That what happens when the cpu is soldred the entier motherboard get thrown
fixing dells has got to be one of the most cursed jobs ever.
Apple and hp are worse lol
They don't make it easy for an end user that wouldn't know how to open up the machine without breaking it to clean the fans. That's intentional. Let's assign the blame where it lies: the manufacturers. They could easily make the machines much more user serviceable but that would cut into future sales.
Ship it to me, I replace those cps I have 6700hq and 7700hq on my bench looking for a board.
Sending it off to the Gooch Collector? 😆
The one and only ;-)
Nice video.
That is one thing I refuse to work on Laptops.
The mobo is still in good shape. It just needs a replacement CPU.
The owner probably did play too much Dustborn :P
The greatest technician that ever lived hahaha
I remember once having a PC that was very noisy. When I opened it up there was a fist sized lump of nicotine infused brown dust. Looked like a hamster had died in it. I've seen some things...
Aww man, yeah we've seen (and smelt) it all here as well.
I have a Dell L701x Xps17.. I need a subwoofer.. This laptop has(had) the best sound of any laptop i ever owned and now it sounds like it's farting from the sub.. I can't find one anywhere. (UK).
Hi, sorry we sold our last one of those in 2020. The p/n is 84TYW if that helps you find one. Best of luck!
@@dellpartspeople Thank you very much for reply and info :)
I would have cleaned that up before I touched it lol.
The most durable laptops are those without a dedicated GPU and with a 15W ULV CPU
Sadly, The Number one killer is overheating, due to poor circulation of Air! The Older Gaming Laptop CPU/GPU are changeable? But lots of these quick built CPU were solder in first than built around it! A can of Blow Air come in 3-4 pack of CO2 air! Caution it can freeze -05' or lower? Hopefully he should found a replacement boards from 50 to 150+ USD? And buy a Good Gaming Pad with 4-6 Fans and once a month to shut down Laptop and blow the fans and intake/exhaust on Laptop until you feel AIR coming out?
Poor CPU 😔
Today's new technology
Dust + cooling fan = a timing machine.
All computers manufacturers are doing this kind of business.
Making this comment early in the video. Probably a bad power connector for not taking proper care to plug unplug it.
*cues SalemTechSperts music*
too much dust, inefficient fans, not getting rid of heat so parts overheat. simple. Keep your machines clean.
This is cool
I felt your comment about the board being the "best design ever" as I helped a friend replace a failing, noisy GPU fan in his AlienWare laptop.
When I looked up the service manual, realized it had to be fully disassembled to replace the fans, I advised my friend to buy both fans because the other one was likely not far behind and I had zero interest in taking it apart again.
What's that USBC power supply you're using?
I want something like that with a display and robust design. Those inline testers you can get on Amazon are typically poor quality, have the output cable permanently attached, and are not trustworthy that they are wired properly for high current.
Just replace the CPU
Dell is apple clones in plastic looks like cheap stuff that makes sounds when you press the plastic
