This was an incredible breakdown of the problem! I love how you walked us through each step so clearly and didn't stop until the issue was fully resolved. Really appreciate the attention to detail - definitely learned a lot from this!
All diagnosis is educated guesswork until you finally get there. I bet the commentors who say you were lazy and should have taken the board out are not trying to fix quickly where time is money. A bit unlucky that the thermal camera showed that mosfet getting hot due to the capacitor exactly at the back of it. Really great you show these ones. 👍
What is really ridiculous is that the service center sends a very expensive bill by charging to replace the entire motherboard (CPU+GPU included) when only one capacitor is shorted. My ASUS laptop is no exception and I had it repaired cheaply at a private center.
It's the difference between module and component repairs. The modern approach is module-based: don't look for a faulty element, just replace the whole board. Faster and easier, but much more expensive.
13:59 - You are not wrong, you are lazy to take board out and we know it :D Eventually you fix it. For celebrating 400k subscribers, I wish Sorin makes a video, not about repairs, to make a video compilation with funny situations from previous videos... there are a lot of them... burning fingers on chip, or that Predator turning ON and scaring Sorin, or introducing Little Friend for first time... etc... even I would like make such video if I get permission to use his videos...
it doesn't matter because the voltage was only 1V or less. Data or control line can take 1V without any issues. THIS is exactly why he sets the voltage at 1.0V......
Thank you, Sorin, for the rich content. I have a question regarding my TUF laptop, which is identical to the one in your video. The issue is that it won't turn on initially, but after several presses of the power button, it eventually powers up. I’ve already replaced the power button, but the problem persists. What could be the likely cause? Thank you!
Sir! i have a question! How to make with your power supply when you check short point, the current UP and the volt Down! sorry my english not good, thank you Sir!
Yes, the fans were quite clogged with dust and fluff. I was waiting for a coment from Sorrin on that. What are the opinions on doing additional work like that if not asked for by customer?
@@melvilib I would remove the dust for free, just not to get the device back for repairs in a few months (dead from overheating and with much more serious problems) :) But the replacement of the thermal grease after disassembly? That's a good question. The liquid pads on MOSFETs and coils probably survive the disassembly, but the grease on CPU and GPU - will not. So it's a good question what to do. I'd ask the customer. And probably put the "phase change" Laird or Honeywell on both boss chips. The cheaper one (like MX4 and alike) depends on the total repair costs - maybe even for free. But TBH, I don't make living on repairs, just doing it sometimes for fun and for friends and can spend some ph-ch paste. In Russian service workshops it's a separate job ("dust, thermal pads and paste refresh - "servicing") and is always paid as unavoidable "collateral job". he same as diagnostics (if a customer confirms to repair, it becomes free, otherwise - it's paid one). But it's up to a workshop owner of course. As for me, I would agree to pay for cleaning and replacement of the thermal interface if not doing it myself (and I probably won't touch it if there's the liquid metal).
Thank you Sorin for the lesson, never stop at First difficulty or First fault diagnosi, bye Francesco Timpano from Florence

Sorin your a genius... Catching that ....amazing. Your the best in the business and I'm proud calling you my tutor! 🎉
Excellent fix Sorin, as always!
One more happy customer. Thank you Sorin.
Very nice laptop indeed! Thank you Sorin for all the nice videos you post on this channel.
To find the positive of the capacitor we do it with voltage or with continuity to ground, to find out where to inject voltage
No positive and negative capacitor , is smd capacitor not polarised , respect the sens injection curent gnd and plus

Good job mate 👏
Great job as usual, keep up the good work. Ps don't forget to replace the capacitor😂
The heat spot on that mosfet was not so sharp, I knew it was on the other side
Sorin didnt replace the capacitor. Now the laptop is gonna interfere with netflix radio edition 🤣
Yes , i like your videos !! Thank you Sorin ! ❤❤💞
I use to check diode value to see whether the MOSFET / the MOSFET package is shorted. So we can confirm it before going to trial n error method
good grose, Sorin, please get a macro lens for that thermal camera
Damn, another capacitor ....... what a surprise ..🤣😂..!! Seems that these caps do not have the reliability that they should. Great work.
Hi sorrin, what will happen if voltage goas to data line or control line accidentally 😮
it doesn't matter because the voltage was only 1V or less. Data or control line can take 1V without any issues. THIS is exactly why he sets the voltage at 1.0V......
Lesson to learn: don't be LAZY !
Take the board out and check both sides...
Not everytime it's easy pizza time...
Have a nice weekend!
👍. Sometimes its hard to differentiate components that get hot on the back of board
Sometime you get lucky witjout taking board out. Sometimes not!
You are the best engineer.
Can I have a Link to your thermal camera?, please
Tricky Pizza... LoL😄

Sorin you are getting older but still diagnosed the problem and did replace the capacitor in different video 😂
Why couldn't you check the mosfet directly after removing it from the board? These mosfets look much different from regular mosfets.
thanks for sharing.
Even though youre getting an older youre still a professor ❤
Now this is a nice laptop tricky pizza yes
Sorin, what's the best way for people outside the UK to reach you and avail of your services? Thank you!
Sir! i have a question! How to make with your power supply when you check short point, the current UP and the volt Down! sorry my english not good, thank you Sir!
Very Nice! 😎
The customer probably closed the lid with something between the screen and frame or the laptop took a hard impact in that spot.
In that case, the probability to get the broken screen is much higher than to break a 1x1.5mm capacitor.
what temp do you use? thanks in advance
Nice one 🎉
what will happen if remove one mosfet from the cpu ?

is no shorted, does crazy..
Another faulty chineese capacitor... It's good that it hadn't taken anything else. And I hope someone had removed that ton of dust from the fans.
Yes, the fans were quite clogged with dust and fluff. I was waiting for a coment from Sorrin on that. What are the opinions on doing additional work like that if not asked for by customer?

Ooh yes😊
11:12 that's def a dog bite
Perfect
Even if there are only two horses in the race you have to put your money on one of them 😉
A happy ending
Why the laptop can work without a capacitor
The Fans are dusty xD
👍👍👌👌
Лови лайк 👍
If I sent an item for repair I would like components replaced the faulty capacitor must be there for a reason!
I would think having a missing capacitor would put more stress on the remaining ones. But what do I know. 😊
He explained like a 1000 times why that is not true
🎉
Ha ha, you are getting younger.
🍕
🍕...
we have pizza ! lol
We have picture 👍
Longitudinal crack on the capacitor... Very interesting.
Hello🤝👍👍👍👍👏👏👏👏👏👋👋👋👋👋
Crack😊
Tube can coz trouble damage board u said dead
eating too much pizza will kills you change your diet🤣🤣🤣🤣
👍👍👌👌
