It's so nice to watch Big Boss assemble the equipment too! Electronics repair involves a large amount of work to disassemble and assemble the equipment, which often takes more time than the repair itself. Congratulations to you both!
When I was a trainee, I had the same experience. I used to joke about how many cordless screwdrivers I could be replaced by. At the end of my apprenticeship, I determined that I could only be replaced by 5 cordless screwdrivers.
I don't get folks complaining about you advertising you care the products you use. To me, that speaks volumes when we see you using those products over and over again, hearing how you rigorously test things before you carry them. Keep making great videos and promoting the products you carry. People should support businesses like yours when they see the knowledge you have.
That's what you call an experience. Man knew it from the beginning it won't work but still gave it a shot and tried fixing it to show us that what problem could be and at the end he was right it didn't work and there was no disappointment as there were no expectations in the beginning itself. Job well done sir.
You are a truthful and honest man, I hope your business becomes more successful every day, thank you for your videos I am watching you from Iran, you are great🌺🌺🌹🌹🌹
Thats why the 4th gen intel alienwares cost that much (I have one 18.4"). You can replace CPU GPU and pretty much all the component and upgrade them separately. It is so sad that newer models are all soldered together as one unit if anything fails on the board its pretty much bey bey or extremely high repair cost. Great video as usual.
I got to say I do use an ad blocker, and it unintentionally skips past your self-promos. I would love to watch and listen to your promotions because your company is genuine in the products they sell and the work they do. Sometimes it skips over before I realize though. You're a real one! Alex
Big fan. Been watching your videos a lot recently after seeing one as a random offshoot. Was never into soldering until I started watching and in the 2 months since, I've fixed a Nintendo switch by soldering and multiple test projects. I've found a useful hobby thanks to your videos so thank you. I'll be making a purchase from your store soon just to support you. Appreciate the content!
Good trying, Alex. Btw, we all appreciate the time you spend making these videos and as a fan, I hope you make as much money as possible from advertising and otherwise so you keep educating us. Keep at it, brother!
My question is why can't you replace the CPUs? Long-time viewer, love the way you go about determining what's wrong with whatever job comes by your workbench.
Great Job Alex. Some people don't get how long it takes to make videos you have to first record the video like you said could take up to a hour to make then to edit the video in total could be up to 3 hours out of your day. I have a lot of respect for you and it's your channel if you want advertise your products then you do do because it's your channel and if others don't like it go to another channel. When you advertise not only do you make a few bucks but I have learned about products I wouldn't have know and I learned what it takes to get the perfect product from the manufacture to your hands and on to the consumer and that also takes time to test them out of your day all for us to be able to have a good product to by and use right out of the box with out a problem.
Great work Alex ,Big Boss! my brother used to say, if I tell you a rooster dips snuff ,look under his wing for the can . As the guy from Adamant IT would say, it is never the CPU unless it is the CPU!
Great video Alex.......only one thing.......... I don't think it's good to advertise your own gear........I think it's bloody brilliant!!!!!! Where else can us viewers find these tools ( which are well tested by your good self ) The right tool for the right job. Whats the old saying: “You can please some of the people all of the time, you can please all of the people some of the time, but you can't please all of the people all of the time” Thanks ever so much for the informative videos, Big Boss is the boss of all bosses!!!!!
thanks alex just by watching your videos i tried to fix a hdd board and this was my first time trying to fix a hdd and i manage to done it thanks to you also once i tried micro soldering and i did it very well again thanks to your videos before i saw your channel i really didnt have any idea how to fix electronic stiff but now i have the confidence to try and so far i tried twice and both time worked great i really appreciate all your videos and i wished i was closer to canada to be able to purchase something from your site but i am in iran and international posts wont get anything here even if we put the problem of transferring the money aside
Good attempt, unpredictable results. I wondered whether there was some test that could determine whether the CPU had failed, prior to new mosfet fit and reassembly. A resistance, diode or current test, perhaps (yes, you would either need to strip a working one for comparison or test each repair attempt and record results)
If they put a CPU socket on the board you could easily test it. Cheap BGA route like all the rest. Imo all supposed high end laptops should come with a CPU socket. Now it's e-waste, ridiculous.
Alex they should use your videos in colleges for their students, but if they do you should could perhaps charge them a fee, something to think about. You are a master in your work, one of the best if not the best I've seen. El Supremo Alex the PC surgeon.
I heard you say that some people criticise you for advertising your products. I agree with your response, but would amplify it by saying that it is very helpful to hear that you only sell things that you have personal experience of. Your product recommendation is very helpful.
It looks like Alienware has an 'Achilles-Heel'.. Infact this information is 'Gold' for the gaming consumer. Because of this channel and the way Alex works, I am starting to find electronics a very fascinating area of study. My knowledge of electronics before was ZERO. Every time I watch a session I learn something. The bits of Philosophy thrown in, are a BONUS...lol It's also a pleasure to watch 'Big-Boss' work...'Poetry in Motion' and good teamwork.....lol
Thanks Alex, yes most of us really appreciate all your effort and hard work not to mention the lessons to be learned by watching and it always puts a smile on my face when I hear one of your plugs for something you sell on your store. Because I know somewhere there is a little brain loser that somehow thinks we all exist for his pleasure and entertainment getting all bent out of shape!
Nice job Alex and Big Boss. I think manufacturers really need to stick CPU sockets on these boards. Especially when they don't have any protective circuitry to prevent this damage from happening to the CPU! It's marketed as a high end laptop. It's not worth what they're asking if they aren't viable to repair imo. More e-waste for the pile.
Agreed, but this is pretty much anti-repair practice. They want everyone to buy a new one when it fails. And it seems to work for them because people keep buying another one.
CPU sockets are pointless if you can't buy the CPUs. Haswell and before were "socketed" but ultimately pointless as you weren't able to actually GET upgrades ever.
@@mr.number9279 The chances of you getting CPU upgrades might be low. But it's zero when the CPU is bga type package. Anyway my point was allowing the boards to be repaired economically, reducing e-waste. Upgrades come after you can implement them. Cart before the horse.
@@anthonydenn4345 Should they be socketed? Yes. I am not arguing that. But the fact that they were, was essentially useless. You weren't getting a new CPU for much less than the whole price of the laptop itself UNLESS it was a special retailer to begin with. Like Eluktronics or Sager or something. And even then, it was RARE they'd just sell CPUs. It isn't repaired "economically" unless you can actually procure the parts.
That is not just a MOSFET. you should specify the complexity of the part you are replacing so that people can understand the difference. That IC is also a driver and buck converter.
Quite right! It's actually a Metal Oxide Semiconductor, Field Effect Transistor! (MOSFET). Today they are probably more advanced than when I first heard the term, years ago. 😆😆
Many thanks for the extra time it takes when you make a video and it's great to see Big Boss showing his skills at putting the laptop back together. For those more knowledgeable than I, is there any way to protect against these particular laptops from going wrong?
at my last job as a computer repair technician i had the same unit with the same issue with that funny looking inductor, with the excess current passing through the mosfet to the cpu. i eventually tested the board in the unit and got the blink codes indicating cpu failure. I told the business owner the issue and he told me not to worry about it because the problems with that motherboard are larger than life itself.
did anyone ever contact you and complain about you saying their product is bad? :))) Your videos are a "must see before buy" and I want to thank you for that!
there is one thing I know for sure after your videos....and past experience myself...dont rely on dell anymore... I have alienware/xps and other gaming and they cause issues even new from a computer shop... respect on your comment you have a family to feed, a business to run, its the billionaires that do nothing that people should complain about ... your papa always looks relaxed assembling a million screws lol
Thank you for making these videos. Don't pay any attention to the dick that's bothered by you selling products. I think it's beneficial to someone to learn how to work on circuit boards and providing them with a place to purchase the necessary tools to successfully repaired one of their own devices. I think most TH-cam videos are shit, like people only reviewing cell phones. You're actually teaching people how to do sophisticated repairs. Thanks again!
Hi, not sure if you will see this but I have an Alienware m17 R1, it works with a charger but as soon as I take it out it turns off tried a new battery and I was wondering if you'd have any idea what it could be.
Damn. All that predictable wasted time. You’d think there would be safeguards to prevent inductor spikes killing cpus when the mosfets crap out. Great video Alex
Man, Mad Kudos to Big Boss! That Guy can take apart and put back together everything!! I have a board that the bios rewrite didnt work correctly and now i get the 2 and 1 flashes. Going to replace bios chip and hope it works. Otherwise Dell has added pw protection to hardware killing code!!!
I'll stick to my 300-dollar laptop from Walmart. It's served me well the past 9 months of constant daily abuse. I never worry about it being stolen at work.
Great job despite, Alex! One question: Why didn’t you desolder after removing the bad MOSFET? Thank you for your tutorials, I really enjoy learning from them, although I never soldered SMD circuits. Best from Germany ❤
My M17 R4 CPU fan broke a few months after warranty. It was doing an horrible and very loud agressive sound. Since Dell could not provide the parts, I finally found a replacement online. Reading the maintenance manual, it was about 25 steps to unplug the motherboard, then 25 again to build it again. Finally, I just use a vibrating tool and destroyed the broken fan. Only 3 tiny screws were holding the fan with some fancy tape... I mean, why aren't the 3 tiny screws accessible from the opened panel? Anyways, now the fan is OK and holds with duct tape; there you go planned obsolescence; no need for big boss precious time... Ahh yeah, also, the monitor broke and was replaced, and now the ethernet port is broken and require a foreign object for the cable to touch the pins. The spacebar on the keyboard is almost not working anymore. At least, the CPU and GPU are awesome and do process quite a lot.
SO, for someone who owns one of those laptops, is there a recommendation to keep it working? Maybe get those all changed to a higher quality component? What would be the cost?
Could it be considered to be a design flaw to not have a small circuit to protect the CPU from Vcore shorts, even if it's a couple of components that will blow up rather than a short hitting the CPU?
yes indeed crowbar circuit will protect the load if overvoltage is trigger but it will hurt their bottom line because the product last very long. btw as a bonus the short circuit mosfet sometimes burn the pcb and 100% void the warranty
Alex... What voltage should exit the mosfets... I am thinking what could i prevent burning the cpu... Maybe zener diode with certain voltage drop connected from mosfet towards ground?
In circumstances where there is a known short circuit on vcore and you know from experience which is the likely FET due to the heat marks on the inductor, it may be better to just remove that FET and check for a short without doing the thermal test. Even though you're running at a low voltage and the current is only 1 amp it could be the last straw that broke the CPU's back. As you say the CPU is probably already dead, but I think you would stand a better chance of success by just changing the FET with a cooked inductor before trying the thermal test. But I suppose you also want to make a video which shows the thermal effect of the short circuit.
Hi alex first i want to thank you alot for share with us always your experience that i already learned many many from you and second i have a question about the coils in general and if it affects or get damaged by hotair or not ??
I'm wondering, would you ever considering replace the CPU (or GPU, or PCH) in these super expensive laptops for a super expensive fee? Of course you need one of those fancy BGA rework stations. Is the investment on those machines (BGA rework) a well justified decision ?
Thanks for another interesting video. A shame that Dell still has this problem with those Alienware laptops, not the cheapest! Are you using a different mic, I do not hear backgroundnoises anymore.
Someone should tell Dell about this issue and remind them to put (at least) the CPU into a socket if they don't want to address this heat issue. At least I have a BGA machine to replace my CPU if anything goes wrong :) Though this knowledge and capability lead me into destroying an old Macbook Pro by installing a Core 2 Extreme quad(QX9300) instead of a P8600 Core 2 Duo CPU, thus making a small home furnace this way :) It worked until the heat made its GPU solder balls melt and crack. Boy it was insane fast though :)
Yep, there are circuits to protect components from over-voltage/over-current but yet they don't use them. It's almost as if they don't want their products to be repairable. 🤔 Nah, they'd never do that deliberately.... right? 😅
Not really. All mosfats are prone to overheating. Chronic mosfat failures associated with a specific model are indicative of insufficient cooling. Part of that is design, while user error plays a role as well. When you use your gaming device on a flat surface without enough ventilation, there's always a good risk of failure.
Could be batch quality related during chip shortage corners were cut. Could be design related, the chips being used out of spec, ie at a current/voltage too high at a high temperature, the user overclocking outside of spec, environment too hot or air/fan exhausts blocked or clogged with dust etc. Mosfets are also sensitive to voltage spikes. If you use an unfiltered powertool running in the 2+kW like a table saw for example on the same phase as the laptop it might die. So a dirty powerline could reduce the longevity of modern electronics. But the main reason is using mosfets in confined spaces where a lot of heat is generated such as a laptop. High end gaming and laptops isn't a very good combination. It's a bit silly really. Get a desktop, you can swap out the faulty component at a fraction of the cost of replacing a laptop. Desktops/towers are much better at handling heat dissipation and getting the heat out, if designed and built correctly.
Hey Alex, if it's a cpu issue would you offer cpu replacement pricing for your customers? Or is it that cpu replacement is not possible? Just curios. Thanks.
It's so nice to watch Big Boss assemble the equipment too! Electronics repair involves a large amount of work to disassemble and assemble the equipment, which often takes more time than the repair itself. Congratulations to you both!

This is where right to repair comes in. CPU needs to be replaceable. I have a M18x R1 with replaceable CPU and GPU. Sad they went away from that.
I'm learning so much, you are a master, I am but an apprentice.
Who's gonna pay my bills? You?
I just loved that comment :D

Love the videos! Keep sharing and stay safe... :)
I'll stick to my 300-dollar laptop from Walmart. It's served me well the past 9 months of constant daily abuse. I never worry about it being stolen at work.
Big boss looks happy in his new cave!
Great job despite, Alex! One question: Why didn’t you desolder after removing the bad MOSFET? Thank you for your tutorials, I really enjoy learning from them, although I never soldered SMD circuits.

are u ask prepare pad? doesnt need if solder tin good enough
Thank you for the knowledge you share with us it means a lot to me ،،🇲🇦
Thanks for the good educational videos
My M17 R4 CPU fan broke a few months after warranty. It was doing an horrible and very loud agressive sound. Since Dell could not provide the parts, I finally found a replacement online. Reading the maintenance manual, it was about 25 steps to unplug the motherboard, then 25 again to build it again. Finally, I just use a vibrating tool and destroyed the broken fan. Only 3 tiny screws were holding the fan with some fancy tape... I mean, why aren't the 3 tiny screws accessible from the opened panel? Anyways, now the fan is OK and holds with duct tape; there you go planned obsolescence; no need for big boss precious time... Ahh yeah, also, the monitor broke and was replaced, and now the ethernet port is broken and require a foreign object for the cable to touch the pins. The spacebar on the keyboard is almost not working anymore. At least, the CPU and GPU are awesome and do process quite a lot.
The only failure in my book, is not having a socketed cpu, again nice work Alex, it's a pity you couldn't just swap out the bad cpu.
Legit question, I'm not nearly as tech savvy as you, why would you not change the inductor as well?
please make a video about your repair tools and why you use them thanks alot am a big fan
very good deduction ...
Now what would it take to solder a new processor to it?
SO, for someone who owns one of those laptops, is there a recommendation to keep it working? Maybe get those all changed to a higher quality component? What would be the cost?
11:52 Thank you Alex

I think it's more to do with putting the wrong type of battery in. See the note at the end about the 2 red, 1 blue error.
nice share …strong team …smart experience …i hope you the best in your life حفظكم الله
Want to see more videos of big boss assembling
I have the Alienware R3 . So far no problems . Running Windows 11 .
Big boss is invaluable. Every shop needs a big boss. Can you clone big boss? 😊
In circumstances where there is a known short circuit on vcore and you know from experience which is the likely FET due to the heat marks on the inductor, it may be better to just remove that FET and check for a short without doing the thermal test.

Grazie.
i like the big boss time lapse
Thanks
thank you!
For someone who has an Alienware 17 R4, is there anything we do can do prevent these problems? Gets a fan, do better thermal paste etc?
why do the mosfets blowup that often? the laptop costs about 1200$?
6:46 correction on what does that tell you, me well dell ur shit , hear me shit 😂😂😂
Good job mate 👍
Hi. Is that a new type of tweezers you are using? Looks different from the one on the shop.

Someone should tell Dell about this issue and remind them to put (at least) the CPU into a socket if they don't want to address this heat issue. At least I have a BGA machine to replace my CPU if anything goes wrong :)
Though this knowledge and capability lead me into destroying an old Macbook Pro by installing a Core 2 Extreme quad(QX9300) instead of a P8600 Core 2 Duo CPU, thus making a small home furnace this way :)
It worked until the heat made its GPU solder balls melt and crack.
Boy it was insane fast though :)
BigBoss have interesting screwdriver. Can you share model and you opinion?
Why they do not protect the CPU against over voltage I will not know. Thanks Alex for all the videos (even the NF adds, to hear what is new 🙂)
if they do that, then how is the CPU going to get broken? no more sales.
Yep, there are circuits to protect components from over-voltage/over-current but yet they don't use them. It's almost as if they don't want their products to be repairable. 🤔 Nah, they'd never do that deliberately.... right? 😅
nice video has always, maybe if you find a dell alienware laptop with a shorted capacitor it will work after the replace :)
fuck netflix. i can watch this guy repair stuff all day like a reality show :D
thanks for your video. i hope this isn't my issue
🎉 thanks
impressed "Big Boss" did a repaste. other channels I watch skip repaste. how? lol. good job.
Has Dell / A/Ware done anything to address this failure issue? What is the fail rate per...100? Does A/W give a replacement mobo? Thank you Alex!
Thanks for your videos
Why do mosfets fail so much in so many devices? Component quality issue?
Not really. All mosfats are prone to overheating. Chronic mosfat failures associated with a specific model are indicative of insufficient cooling. Part of that is design, while user error plays a role as well. When you use your gaming device on a flat surface without enough ventilation, there's always a good risk of failure.
Could be batch quality related during chip shortage corners were cut. Could be design related, the chips being used out of spec, ie at a current/voltage too high at a high temperature, the user overclocking outside of spec, environment too hot or air/fan exhausts blocked or clogged with dust etc. Mosfets are also sensitive to voltage spikes. If you use an unfiltered powertool running in the 2+kW like a table saw for example on the same phase as the laptop it might die. So a dirty powerline could reduce the longevity of modern electronics.
But the main reason is using mosfets in confined spaces where a lot of heat is generated such as a laptop. High end gaming and laptops isn't a very good combination. It's a bit silly really. Get a desktop, you can swap out the faulty component at a fraction of the cost of replacing a laptop. Desktops/towers are much better at handling heat dissipation and getting the heat out, if designed and built correctly.
because the method to monitoring current balancing per phase a little bit of black magic using parasitic resistance of inductor
aging
This company is doing this intentionally, by which people will new one again 😑
Is it worth reballing and soldering another CPU?
Or would it be too complicated?
I would love to see it once 🙂
NF have lot repair order. reballing need more time. he can if needed.

Hey Alex, if it's a cpu issue would you offer cpu replacement pricing for your customers? Or is it that cpu replacement is not possible? Just curios. Thanks.
