Laptop motherboard, diagnose & and repair tutorial

[@eugrafcmg]

I fixed my very first motherboard using your lessons, you made me so proud of myself! Thank Sorin for all you do for us!

[@noaha8915]

Living the dream dude! Congrats.

[@eugrafcmg]

Sorin, above two comments are bots made to scam people. I've tried to report them but you can add filters for your chanel so words like "Flixzone" won't appear.

[@krystelfreeze4906]

Did you have to buy any tools? I was trying to fix my laptop but a chip was burned last night due to the broken DC jack. Now I dont know if It is safe to replace the DC jack and to test on the mainboard one more time

[@eugrafcmg]

@@krystelfreeze4906 try to learn from this channel and do something when you ready. If you just want to fix ones with no tools why these guys don't work with bare hands?

[@TheSpeedbones]

Same for me

[@rbraam7943]

This guy is brilliant! So honest let’s you see what he does. I have a background in electronics, but fixing laptops is very very different from theory. He goes from problem to solution in the most straight line using his immense experience. I’ve learned so much already!

[@scottpeeler1569]

I have no idea if I'm actually learning something or not, but it feels like I know more than when I first started watching this a few months ago! Thanks guy

Excellent, second video i watch from your channel, u will have a subscriber from Colombia living in Bolivia Country, thanks!

[@paparazzo80]

I simply love what you do,though not understand many things relating this,but watching your vids makes me a bit happy.Sadly I got covid and my health prognosis is not good,but all I wanted before I die is to meet you and you teach me repairing laptops...keep the vids coming master Sorrin.

[@westhenry9360]

You ain't gonna die please... That's too negative to say.. Where are you from ? Hope you don't mind chatting me up?

Thank you and welcome back Mr Sorin, watching from Davao city Phillipines. Stay safe.

[@epicnaturals4763]

You should do a video explaining the components and what they do on flight controllers and electronic speed controllers for fpv drones. It's a rising hobby and i love the way you explain things!!

My name is Solomon I am a Nigerian I repair computer but I want to understand the mother board of the computer. Thank you very much sir for the classes.

[@whatdapakq]

sorin you are a great man and teacher keep it up. thank you from philippines.

[@1matejus]

if i saw well the GPU has 3 phases, removing one mosfet the GPU works in two phases and so also gets feedback from the other two coils, the GPU will work but at full load it will run out of current one phase less current is missing

[@Mustafay3sil]

I thought the very same thing and was about to ask on discord server and saw your comment.

[@Dmiliunas]

i think the same. i was under impresion gpu had 4 phases. Sorin simply disconected one phase and laptop will work fine untill gpu ask for more power, then two things will happen, either laptop crashes, or gpu will be limited and throttle back. I had Desktop GPU with burned phase. had to remove both low and hi mosfets, driver and coil. gpu worked fine but showed lower scores on benchmarking.

Thanks Sorin for all you do for us, god bless you, keep you healthy and away from harm

[@jubzlightknob9560]

hello sir, i think that laptop has dual graphics, removing that dual mosfet for graphics power supply disabled the graphic chip (nvidia/radeon) and the laptop automatically switch to intel display , that’s why the laptop has still display you may check it on bios setup or device manager ..as always you are my first laptop motherboard repair teacher,im forever grateful 😍😇🙏🏽☝🏽💻

[@eliemazraani1685]

Your a generous man and a great teacher, thank you

[@monsentertainment3682]

Thank you for being a good teacher!🙏😘

[@salviereypayacda5934]

I didnt notice i spent an hour on this video lol. Very informative

[@4Relax]

It is the same like in the pc grapics card if you have 4 phases you can run with only 3 only problem is shorter life time of the other 3 phase. I test it on benchmark and it is working normaly but i will put mosfet back because of less stress to other 3 phase. I learn so many things from this channel.

I've seen your first video last year November and I was like wow this guy is demn supper good with fixing laptops, on march this year I came across the video were u were advising on opening a repair shop , and I liked the words u said "just do it" I've managed to buy most of the tools now , I'm still learning from u all the way to Swaziland

[@zambattmovcon7827]

looking forward to buying some tools as well bro

Hi from Greece ! Thanks for videos!

well done asus. great design ( as said on the video). i own 3 asus products, my zenfone 6 had faulty mic jack and a scratch on a new screen. i'm happy they took responsibility and repaired everything for no cost.i love the new asus rog zephyrus model with keyboard pulled back.

I have a lot of faith in Asus products. I've just replaced an 11 year old motherboard for the only reason that the water cooling system had a leak and killed it. Rock solid products.

Thank You so much Sorin i've learned a lot from your video its more than a year since ive subscribed to your channel and so far I have improve on laptop repair skill. Thats why im so grateful to come across your chanel been watching all your videos almost everyday, I even save it on my harddrive for my references :) Thanks so much more power to You and Your Channel. God bless.. keep on sharing ... its me Erick from Philippines

Good to see You Sorin !

[@SleepToTheSounds]

You always remove chips and components so quickly and with precision !

[@koloxd3]

Great to see you again

[@tanishqbhaiji103]

Sorin, you don’t have to replace the mosfet on modern Multiphase converter it can detect and not use the Missing rail, it will work but it is not ideal for law phase count or high power draw. Buildzoid from Hardcore overclocking channel always does this.

[@BurgmanRC]

Mr. Sorin, what you take out from the apple board is not a dual mosfet it is a mosfet with shotky diot inside. Dont trow it away it is a quite expensive part 😁

[@seckinseckin3919]

We use this low side mosfets always as a diode.. check buck converters

[@sodiumtechnologiesug366]

This is great.thanks Sorin

[@noaha8915]

[@asv5769]

Thank you for this video Sorin. It is very educative, especially because of the example where power management chip via current sensing input resistor did not see short and thus shut down input Mosfets. In this case resistance was high enough not to trigger input Mosfet but internal protection in the charger kicked in.

[@mattstroker3742]

Hello hello master! Good. To see you again.

[@djakeanddewchannel970]

always cool mr.sorin , when you host your show ..love it

[@Vasilis_Parlamentas]

Hello Sorin! Because you removed that dual MOSFET you cancel one of the 4 GPU power phases. So either the super io regognise that and work that GPU with only 3 phases meaning that maybe laptop cannot overclock that GPU or push it to the limits. OR laptop will crash when some heavy application (like games) force that GPU to work under full load and needs all 4 phases.

[@seidumomoh7791]

Sorin is the best

[@argee99]

Excellent, as always. Thanks for the video and knowledge...

[@milskater]

good video sorin!

[@dciking]

From stabbing many GPU input inductors in my repair attempts and sanity checks with known-good cards, 0.8Ω is normal for the GPU Vcore resistance. 1.2Ω (older cards) to 0.6Ω is typical, depending on the GPU.

[@josephwilson3573]

I am an electronics technician with a 2-year associates degree in electronics technology with over 25 years experience in both board and component level. I live in the State Of Maine, U.S.A. If a tech is in business to repair computers in this case to component level, it is always a great idea to have a good stock of components, and Mouser Electronics LLC is an international distributor, and possibly Digikey in Thief River Falls, Minnesota. Use ESD protection such as Faraday Shields, and a grounded bench mat, and a grounded wrist strap, since as little as 12 Volts of static electricity can damage permanently components! Follow my good advice, and you always will get great results!

[@georgypushkarov9510]

Good video!But i think here is a switching graphics and now the discrete is not working ,only that in cpu.

[@basharatullahrahmat971]

My Zephyrus hasn't turned on again for 7 months now after changing to discrete graphics. Do you think it's has to do with that setting? I took it to 3 techshops to fix and none of them could.

[@seckinseckin3919]

You sure it is automaticaly can turn discrete to UMA ? I know the only way to change it with hand operation, changin some parts
