That chip the sic 632 is commonly used on sapphire polaris gpus. If you have them laying around you could easily have one for a donor.
That's correct, it can also be found on some nvidia gpus as well. Was that the discrete graphics power delivery circuit on the motherboard?
That's what i was about to type until i saw your comment haha
Rx570 hs it
Only real electronic engineers like yourself have the skills to diagnose and repair down to component level these days, in the mid 1970s I was a TV engineer doing component level repairs. Today it has become just a case of board replacement or “panel bashing” as we called it. Great to see real repairs still happen in a proper workshop.
Good progress from last asus video , that's how you supposed to do it when cpu getting hot checking voltage on coils will tell you if a line is shorted tho to be save use 0.5v not 1v (alternatively you can point negative multimeter probe on current sensing resistor (big low ohm resistor just after 2 protection mosfets) and positive proble on all coils and the one with similar resistence to current sensing resistor will be shorted) now saying that cpu may be still dead in this case its a 50/50 scenario....if aftet replacing that drmos you'll get error code 2 red 1 blue that's means cpu died ....also you can check svid alert# signal and svid_data svid_clock with oscilloscope to confirm if cpu died.....
6:29 "the short is gone" Epic smile👍
That was not just lucky but experience sir! Good job!!
A real technician doing work ,I will say what everyone is thinking since most technical support are forced to abide by a insanely limiting insurance contract or using inexperienced guess work without it training or troubleshooting which would allow for repairs without fixing the actual problem of the system not working or turning on it's very annoying.
Very nice fix again, the coil you removed to measure also looked much more brown/discolored then the other coils but amazing how good you are at fixing things. keep up the good work en nice learnfull video's.
Trust me, the job is done, even without the chip, it still going to work 💯 except when in intense usage mode, when the m processor requires more power to work. I have fixed many similar issues like this in the past. Am taking from experience thank you
Your videos keep people motivated. Thanks
I build a lot of pcb's for myself and I learned from watching you how to get rid of shorts on SMD IC's. Originally I was struggling a bit to start but with a bit of practice I can do it well now. The drag method works well.
This guy is exactly how you think an engineer would look like, sound like and behave like!
Very good job. I love those videos where you explain us so much. We all learn a lot from you. Big thank you
Am glad you made this video. I had a bus accident with my M17 r3. After the accident, I turned it on but to my greatest surprise it came up but the screen was broken so i used the HDMI port to my TV. Everything was fine, only that it was not charging when I plugin my charger. It refuse to charge until the battery ran down and the laptop went off. It not been able to charge up till now. Could this be a DC IN POWER JACK problem cos I was told the laptop can work like a desktop without the battery? No sign of charger going into protection mode like you showed in your video.
Always good to see you smile when you find and solve.
i appreciate your work. That chip has dual mosfet with pwm. The upper mosfet was short. So 19v directly goes to cpu and create short. May be the lower mosfet and upper mosfet inside the chip short cause the problem.
Muy bueno , siempre guiarse por lo mas obvio , si vemos un color diferente al resto puede ser un buen sintoma para detectar el componente quemado
Always love these. Also I love the outro song lol
It’s like a little celebration party of the completed job!
I thought it's a RIP when the thermocam pointing to CPU
exactly what i thought especially after seeing the other laptop video, he said "no fix" after seeing the cpu hot under the thermal cam
The CPU work with low voltage that why he should remove the Quartz oscillator for the CPU or go for low voltage it is depends of the datasheet of the CPU some work with 1.8v but maybe less
You really get a kick When you have fix some and get Happy .. really Nice to see you videos
Your experience in this field prove your expertise. Nice always watching your videos. Good day!
Great video no luck involved shows your experience and knowledge
Yo Alex ,we seriously need those T shirts in the store.Like " the short is gone " or "better than factory" " this is the real hiroshima"
That smile is so good if enything watch these vids for the smile its so happy :D
Yes,what a luck.In many cases the CPU or PCH are shorted and that`s game over...Nice video as always!
nice laboratory! congratulations bro!👍
T-shirt: "and the short is gone"
👍, these buck converter circuit should have protection because once the mosfet goes bad a direct 19v will be going to the cpu, assuming the customer tried replugging that short pop 19v will be damaging the chip nad then dead, thats the common way you will destroy the device, so we must be careful , even at injecting voltages😅,
Love to see your smile when you figure out what's wrong ^_^
Any chance of 4k/1440 content in the future? Keep up the good work. ✌
Well done! If you hadn't noticed the discoloration on the chip and the coil you could thought that the laptop was unfixable? This is obviously experience but I ask because the thermal cam pointed the CPU.
you're number 1 greetings from Italy
I would add a paint marker spot to the replaced parts on any
job so that the customer can see exactly what was replaced. Also a good
reference for repeat work so that you know what you did the last time it was in
the shop. You might buy one of those airplane seat cushions for your BUTT that
is spot welded to your chair. I know that you spend a lot of time in that chair
or "the thrown of genius" that you make all of your diagnostics in.
Maybe get a treadmill for your aerobic work out to keep your brain well
oxygenated. So, when you are working on something that you can't figure out,
jump on the treadmill and get the blood pumping so that you can think more
clearly. I do that by just taking a brisk walk.
Great show today!!

Literally my exact model and my exact issue. What's this cost? I'll mail this to you right now lol
Dear Alex Im a little confused , why in another video after injecting voltage and seeing that the cpu got hot on the thermal cam instead was diagnosed as a "no fix"? hopefully somone can clarify for me
i have the same dought
the cpu got hot with no other signs of damage in the other video, however on this one he spotted the chip that had obvious signs of overheating on it.
I lost a big portion of the recording in the previous one where i explained why the CPU was faulty. When I was editing I realized that I didn't record that part so i made it a short video to shows that sometimes we do get laptops with a CPU short.
@@NorthridgeFix it would be such a great idea to further expand over the cpu short topic in a future video. Thanks Alex, really appreciate you
@@NorthridgeFix thank you for your reply, got it, as you said many times visual inspection always important, in this case the thermal cam kinda deceived
Great work indeed. . Applause. . Would you please make a separate channel .how to dissemble whichever devices you are working at. Thanks. . dissemble is one of the most and difficult job indeed. Anyhow. . Thanks
Theres no luck in your work my friend, its all about experience,
Man, he's so quick
I like that, your way to presentation .and keep going may God bless you.
Thank you for the video. Why did you keep investigating after you saw the CPU heating up? Usually in your prior videos after voltage injection you see CPU heating up you would usually say CPU is a problem, motherboard cannot be fixed. Curious to know. Thank you :)
because this is how you're supposed to do it. Of all the ones before where he just abandoned them when the CPU heated up, at least some of them could've been fixed just like this. I don't know why he didn't do this before, just trying to save time I guess
@@danandrei96 I guess CPU side MOSFET fixes are usually tricky and you cannot really inject too much voltage i.e you will most likely burn the CPU rather than fix the circuit at that point.
I’d have to watch his videos on the laptops to confirm but typically when a CPU is still short, after you remove the upstream problem, the CPU is usually dead. Or, when you can’t find another problem upstream of the cpu, then the cpu is the problem
Good learning friend, thanks for the teachings, I have an alienware 15 R2 that does not turn on at all, when checking I found the power jack connector burned out, the white one where the connector pins go, physically you can't see burned or burst transistors, I have to check to find the short or the fault, thank you very much.
Probably the cpu hasn’t survived getting 19v straight to it. At least one phase is burned, so it will turn on but won’t get into OS. Just my educated guess.
Very good friend!
I have the same issue on my Alienware :D same pop when I plug in the power. I tried to Messure the connector but really don't know how to work with the voltmeter. Can you repair my board pls? :) Your Video gives me some hope. A new MB is to expensive even on Ebay.
If there is a table of equivalence for different used ships in motherboards that would be helpful, instead of searching donors or waiting long time to receive the exact model.
Would love to see how you mounted your magnifier on the anglepoise arm to your desk as I am having some difficulties with mounting mine as its a very heavy Luxo ex military and all I have is one of them silly friction clamps. The clamp is of metal and quite strong and just want some ideas as I don't like the idea of dropping a very heavy lens and fluo tube onto my workspace lol
great work mate
Nice find!
Always good videos from you i love you channel , when regulator voltage is very hot 3.3v and 1.8v is dead reg ? for 10 sec is hot !!
OMG! that was quick!
Amazing find 👏
Good work 👍 see you next video ☺️📸
good job mate.
Magic!
Really nice fix.
Nice like always
Great video 👍
the job is done😊😊😊😊
Thank you for sharing
Thats not luck its hard work and experience💪
You are the best
Regards
Amazing! Keep going
Why was the short present when the board was hot ? And disappeared when it cooled down???
Awesome job bro keep rocking 👍👍👍
Nice job
Good job
Nicely done. I hope I could figure out what's wrong with my laptop. Turning on for 3secs and off and repeats 3times. Sigh.
Well done
I don't understand. The Thermalcam shows the cpu as hot spot and you said there was a short on it. How and why you looking for another short sorgent?
Seemed Easy but possibly only though experience.🤩🥰🥰
Sir thanks nice work
Good job 👏
You are awesome sir🤗
good job
Thanks .....
Great video
great job
thanks
Good job SIR
How much did you charge them to fix this? I have a Alienware area 51M R2 and no one can figure out my problem and I've been without my PC for ages
What is the most common cause of that chip going bad? Overcurrent? Overheating?
My m15 r3 is on the way, hope you can fix it :)
Very helpful
I have a same problem I can't find the IC and coil in my local market where can I find the parts . Please suggest ! I really need your help.
Good Job
Why did CPU get hot but not 632 chip. We see it's already discolored from heat but when you inject it's not hot? Confused.
Love your videos ! :)
how do you know were to inject the voltege do you have the schematics to the componnets
like on the mosfits ? or do you put 1.2 volt on any leg
He just follow the the wires for example he know the input or charger he can put it in this point or sometime you put ground to ground and inject low voltage to the + of capacitor if the the other leg is connected to ground it must be a big chemical capacitor with polarity and voltage writed it should be a voltage filter capacitor
Did this actually work afterwards?
I just performed this same repair and afterwards I had the 2-1 flash code indicating bad processor.
After searching around, I found this video and saw you do exactly what I did and get the exact same results, but then the video ended without showing the thing actually working.
So I'm interested to hear if this actually worked after replacing the SiC632 IC or if you successfully fixed the short - as I did - but found later that the computer itself was destroyed.
Thank you!
most likely cpu is dead and game is over
i have the same problem with the same board same chip but when i turn it over in the same spot there's something that melted off theres 3 little i dont know what u call them but one is gone how much would you charge to fix?
Good job sir
Mr. Alex, my laptop has a similar problem. It won't charge and the charger goes into protection mode. I bought another charger and this one doesn't have protection. This way I found out that 2 chips are broken because they started to get really hot. (right near the DC_IN) The problem is that I don't know where to get them from to replace them. They're shorted from ground to source: TPCA8057 1N DFN5X6-8 and AON7380_DFN3X3-8-5. What should I do? :(
I didn't really understand the diagnostic method @ 2:50 can some please explain the theory behind this diagnostic method.
Thank you
Which brand of laptop has fewer problems?
Nice
so, why the CPU was shown on the thermal cam and not this IC ?
Hi sir I recently got a alienware x17r2 and as I plug in my whole laptop shuts down and unable to boot up, this is just 1 month old, is this Normal? And how much to fix it ?
GREAT VIDEO,WHEN YOU SAY DIODE MODE DO YOU MEAN CONTINUITY MODE AND WHY DO YOU PUT POSITIVE ON GROUND .
awesome skills... that not luck
I have a alienware m17 with same problem. I'm from North Carolina, how can I send mine to you
Hi. I love your work usually. But you didn't show the display turning on after the MOSFET replacement. 99.99% of the time, when AW laptops have a bad MOSFET or VRM etc, it will kill the CPU. There is no 2nd guess. I've got 20 AW laptops with me all with blown MOSFETs and VRM... result CPU are all DEAD. And I can also confirm this this with my old friend at AW in Athlone (Ireland).
Anyone know why Alex removed the coil to show that the chip was shorted? If the coil is unlikely to be the problem, why not remove the chip?
