Gaming laptops classic disease - Shorted CPU/GPU mosfet - Msi gaming laptop repair 

GPUs are actually way more resistant against shorted high-sides than CPUs. So there is always a way higher chance it actually survived. Recently i had a really challenging case on my bench where the the DrMOS was welded with a few board layers and it was necessary to dremel the short out of the board. After the restauration of the tracks and replacing all related DrMOS it turned out the GPU is working absolutely fine, like from factory.

تحياتي استاذ سورين انت ملك الصيانه وشكرا لشرحك الجميل اعتذر لكتابتي باللغه العربيه

"This is a nice MSO laptop" , opens it and it's disgusting lol, that was a laugh out load moment for me anyway. Some people have no shame, you'd at least clean it before taking it to get fixed etc. Minging doesn't come close, I'm not surprised you put gloves on for that one.

Thank you sir, you have really boost my knowledge .

Hello Sorin! On my laptop (Lenovo Legion Y720) the HDMI/DPort port is only driven by the Nvidia video chip, the integrated Intel can only show picture on the built in screen. Learned it when i replaced the old battery to a identical looking one and the laptop kept shutting down when HDMI was connected/game started. The problem was the BMS in the new battery it was only able to deliver 5 amps while the original did 9.

Salut. Am fix un laptop ca acesta, a facut scurt de la mufa monitorului.. Sper ca specialistul care mi-l repara sa fie la fel de profesionist ca dvs! Spor la treaba!

Thank you very much dear teacher Sorin. Thank you 🙏😊🙏🙏

great video sorin ....a standard charge for just opening the laptop is the way to go ..then if gpu or cpu are gone you still get paid ..customers pay for your knowledge and experience ....and labour ....

I love the videos of gaming laptops..a follower from Libya..greetings..

Good job mate 👍

Good job mister

If you measure voltage (mV) across coil while applying power supply to find a short you can exactly find one that is under load and a co0rresponding mosfet is dead.

Thanks for another great video. Upgrading my cheapo microscope. Have been looking at the amscope microscopes. I have been meaning to ask you on your other videos. What microscope do you use?

great video as usual , but i have a question why they do not design power supply such that if the control chip detect over voltage situation due to shorted high side mosfet it also energize the low side mosfet to create a dead short and save the cpu ( in this case the charger will probably cut out due to very low resistance short)

md Sorin....specialist of computer hirurgy :)

there is some rly sensitive ppl i also had in my life so many times little scratch which was from opening laptop and trey cry... so now i tell them its not made to be dissembled and little scratch like that sometimes happen sometimes not depend how hard is laptop to disassemble it some are just screws some are painful plastic clips which will leave tracks of opening for sure...

Nice one

the tools to detect shock me, even I saw it on cellphone repair it have similar

personally, would jump mosfet with a wire if power on one side only, to pass power on, if there is a short after the mosfet then i look at inductors that should be always powered on at the rail and not to ground, if grounded that's the short issue

how do you know exactly where to look :) you're genius .

nice bro...from phillipines tech

you could use your own nvme with windows and test the gpu, with the gpu-z test just to see does it work

I always clean the laptops.even after a mundane job like hdd to ssd.The speed will make it look like new,so the cleaning will add some wow effect on the customer.Its the "good as new" experience for them.Never I had complaints about scratches.However I'm sure someone will say that in the future.Its inevitable .

Why don't you use your own test SSD? I have a sata and PCI-e one and planning to get an external USB one too. Way faster than having the customer test it or ask for the password and have problems later. Multi phase VRM high side shorts can kill GPUs, but in my experience they are way more likely to survive than CPUs.

welcome aboard agent sorin with those black gloves 🧤🖤😂

Hot hlue for hinges is not the best solution. Use 2 component epo compound. And clean hinges with air and loosen hinge nuts a bit. Msi has not learned since.. cx620 had same kind of issues with hinges and all theze gamings are even worse.. hinges have so little supporting material, sometines i have to use soldering iron to fix the base to its place before using epo.. yesterday had to repair sony vaio s rumbling cooling solution but first the case.

Im scared of that happening, i litrally bathed the mofets with k5pro

Sorin put transparent plastic film at the screen around the screen and dont scrach the plastin. I dont know if i explend good. Just put some platic film around the display

Hello, I bought MSI Gaming laptop 4 years ago, bought the warranty for a year. After like 14 months, something on my GPU shorted out. It caused massive BSOD crashes somehow even after disabling GPU in device manager. I sent it to MSI Tech Center in my country, explained to them to inspect my GPU because it's not working properly and they sent it back with a lovely word "Repaired" One advice for people reading this comment? If you want to game, buy PC, not a laptop. And definitely not MSI, if not overheating then shortening chips/mosfets.

Omg jaja... Scratches hidden under the dirt xD

Pleas order that tship and do secand part

Hi Sorin I understand this point driver chips is gone even you replace it not worth to fix gpu problem BUT YOU KNOW IF YOU DISABLE THE GPU POWER OR DISABLE THE GPU THEN WE CAN GET DISPLAY FROM INTEL (if you leave it like that it will enable the driver question mark in device manager and pop up the message every single time in every update) or if you do modification in the bios?

verry creat sorin and pump your glove

Is it possible to turn off option to switch to nvidia GPU in Bios?

Fine graphic laptop video sir update videos sir

Why don't you use some live boot, like medicatusb or whatever else, to test laptops w/o need to use customer's operating system?

What caused the issue ? What model laptop is this ? Awesome video by the way. Fantastic job

So if the current drops it means it's a short in the mosfett?

Could the GPU have died due to one of the fans not running, causing that part of the motherboard to overheat? Any idea what all that white-specked stuff is that looks like it has fallen out of the keyboard, leaving a white-specked silhouette of the keyboard on the screen? Just wish I could afford a decent Flir thermal camera! Great stuff.... KW.

4:17 in which video you use this method?

How are you gonna test if the GPU is still alive? It would be interesting to see the test process as well. Thanks! 😊

Hie my boss, been watching your clips for a while. What courses can I take to be at your level, from beginner, to learn about those small components!

I have a similar MSI laptop, and have anxiety of spilling drinks over it (comes from one time I almost burned my apartment with electrical device) what if I spill liquid (tea) accidentaly on the keyboard - can it short circuit and catch on fire? or it has some kind of a fuse I understand that the first thing to do is to disconnect the charger and hold power button for emergency shut down but still is there a chance that a fire will start so quick there is no time to react

Sorin, HOW you can be sure that GPU is good? You let us wondering. Why? Will you find the same laptop and use chip from it to check or there is some other way to check GPU?

Salut,in bios ar trebui sa apara placa video daca functioneaza,cel putin la Asus apare

Wow that is one filthy beast

Oh No Sorin got his Hitman Gloves On...

name of the screw driver u r using

Lots of star dust in that laptop!

I had the same problem on Acer Nitro. One of the DRMOS was blown with a hole in it. After removing that DRMOS the laptop came on with yellow mark on Nvidia graphic. I thought "hey, looks like it is still alive". I ordered the chip for 20 pounds and after soldering it blowed up.... Right now I'm not gonna repeat that decision again 😊

Hi Sorin! Tested your method with hot glue for hinges. I dont know... its isnt holding... dont know why. may be because all stands were broken. By the way did you know that hot glue is very easy to remove with alcohol? few drops and its just pops out of a surface! So i made it my way: covered hinges with capton tape, mounted bolts and nuts, soldered peace of rigid wire to the nuts, filledarea with overheated hot glue and sadwithed all that. Now its like new, you can unmount hinge and nuts are firmly holding its places.

Hello, for the business purpose it's good to use a term or camera but for learning purpose we need to see how to find this short thanks

at first i thought you are saying: this laptop is dirty 😂😂😂

can we know the mosfet model number pls?

MSI I have one of this(gv62)

why I never see mini pc repairs , are they more reliable ?

Hi Sorin! I have a Lenovo Ideapad Gaming 3 with Ryzen 5 4600H and GTX 1650, my gpu seems to be dead, no output from hdmi port and in the device manager it appears an Error code: 43. What shall be done? Can it be repaired or shall I replace the complete mobo or just buy a new machine?

The middle mosfet again.

light games can also maybe make the gpu go 100% stress if no fps limit settings are in place is not that hard to learn some basics of how to monitor and how to set settings for less stress and heat for example lower temps and and stress in games just by limiting the fps and resolution and quality settings and power settings maybe an example for this video will go like this so as a speculation example maybe now the gpu can only do around 50% usage at max core clock speed and needs to be limited depending from app to app also light games can also maybe make the gpu go 100% stress if no fps limit settings are in place also even on hard games the gpu can stay at around 50% and it can maybe be ok also 100% usage at more less core clock speed is not really maximum stress also games tend to chaotically stress the gpu depending on the complexity of the scene as some levels may be light and some may be heavy also this example is more of a speculation for the video as of how stuff maybe correlates more or less

Cum putem afla daca gpu e bun? In acest caz.

Your think they would clean it before sending in for repair,I certainly wood

Can you help me sir please ? I gave my properly working gaming laptop to just put thermal paste but after i got my laptop when i plug in , my graphic card acts so weird and fps shuttle when i plugged in but properly fine when i plug out

Got same Msi gaming laptop when charger in charger light turn off cut off

It makes me sick as an IT Security Tech is that people complain when you clean their laptop during repair. I get alot of dirty/filthy laptops in for basic upgrades or diagnostics and i refuse to work on them until they are clean. I use a microfiber cloth with just plain water to completely clean the unit before i begin my repairs. I have NOT gotten a complaint yet but if i do, i'll tell them that i cleaned the laptop with items that will not cause ANY damage. I just can't work on a filthy laptop.

I have questions I want to buy a laptop it's have a i7 13620h they told me if pch burn you most change the motherboard completely is it true??(asus zephyrus g16 4060)

Why don't the manufacturers have a "protection circuit" to protect the CPU/GPU from getting nuked by excess voltage or current.

Hi I have an MSI GE75. My screen has been damged so I had to replace it And when I did that I forgot That it was plugged in So When I attatched the new screen I saw a quick flash in the place of attatchement and I heard a small pop noise and everything went off. When its plugged in it doesn't show anything and everything is dead. If you know what is dammaged plz help me. I had to work to get that laptop the entire summer to help me with studies. sorry for my bad english, its a 3th laguage for me.

what model of thermal camera is it?

i think this mosfet failed for msi asus gaming laptop so what you propose for me in brand ?

i bought hp victus 1yr ago...and now my nvidia graphics card is not working nor showing up in task manager or device manager....is there any chance this is the problem for my laptop...here we dont have good technicians like you....😢

Sorin, laptop-ul ăla parcă a stat în cotețul găinilor. Cum poți folosi asemenea aparat pe care trăiesc o mulțime de vietăți microscopice?

Next video, testing the gpu.

Omg

its quite simple......there is no "gaming laptop" on the market that can handle to amount or powerdraw/heat over a long peroid of time! to small, to hot, too much generated heat on a small surface. Its like a small city car, with a v8 engine! you can drive few ours with this, but in longterm, it will not last long! if u want a "Gaming Pc" use at least a ITX CASE and usual ITX Parts! Consider, good Mainboards has a 14 or 20 Phase Vcore. Laptops has just 4 maybe 6! it cant go well in long term

At 3:16 you say “I don’t think the main power rail should have 36 Ohms”. My question is: How many Ohms should it be, roughly? Please let me know, I want to learn. Thank you kindly sir.

0:48 lol

Those mosfets like to blow

I have a laptop asus tuf f15 and its gpu is not working. Service center told me that my gpu is dead but my gpu is showing in device manager as hidden is it dead or what

I have MSI KATANA GF 66 11UC My laptop repairer said that its CPU is short circuit and we cannot change the CPU or repair it. My laptop was on charging and it was shut down but in the morning when I tried to turn it on its keyboard lights started blinking as I pressed the power button. Please give me any solution 🙏

Why is it always the middle Mosfet? :)

wow , this one was very dirty . customer should clean keyboard

We should start changing cpu and gpu and pch for these laptops

PLEASE HELP Hi , I been watching your videos , I love them. I have a msi laptop very similar to this video. I bought it and put a hdd in it , got it working nicely but never had the opportunity to even play a game on it 😢One day it worked fine , the next time I went to turn it on and nothing , no power or nothing. I had a bad charger port so I generically fixed it , got power to the board but the laptop still wouldn't turn on. I put new thermal paste on whole I had it opened up and as I was putting it back together I noticed a cable not connected. I connected it and the laptop turned on but had a black screen. I turned it on and off a few times no problem but still black screen. I pressed some buttons on the keyboard and it shut off again and I can't get it to do anything again. Can you please check it out if I send it to you or something please

Looks like half of Peru in that keyboard....

This laptop is dirty, lots of dust.😮

Update. I got the laptop to turn on but black screen . Update the laptop went dead again no life at all. Update, I got it to turn on again and screen to come on but it's stuck in bios . Any help ??

me watching in the same laptop be like 🥵🥶

If would like to not know what was the laptops problem from the start . Is it a good idea to not include it in the title ?

Sorin, I see you usually working without gloves, why this time ?

gpu cant repear !!

connect Hdmi to external monitor ,if worked your GPU shall be fine

It's not a technician job to clean customer devices its by choice some pple are just too nasty i couldn't have my laptop looking like that and if so I'd clean it before sending it to repair very disrespectful

Just so that you can be as grossed-out as me, that flaky stuff that fell out of the keyboard and onto the screen... yeah that's skin flakes from the user.

te am prins :D

Give the customer a brush and a alcohol 🧻and they clean themself before you take it. Bacteria 🦠 clean

Yikes, the keyboard/display was filthy. Gamer needs to lay off the donuts and hot pockets.

You should wear mask also!

good grose... what disgusting people are out there, that doesn't even clean their shit before they send it out for repair.... man, i don't want to see that home where this thing is used. 10th gen isn't that old, how tf can you break this hinge so fast... just terrible... But Sorin, the integrated Intel Graphics is in the CPU since Core i series started. It's not in the nothbridge anymore.

ngl imma get old and repair my laptop myself my country laptop repair shops are nothing but fckin scams i already got scammed like 7000 rs already

Lptop is a health hazard. Are you sure you don't want to clean it?
