I fixed my very first motherboard using your lessons, you made me so proud of myself! Thank Sorin for all you do for us!
Living the dream dude! Congrats.
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.
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
@@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?
Same for me
IVE BEEN I REPAIR TECH FOR 27 YRS. IVE LEARNED MORE FROM YOU. THEN I DID IN MY FIRST 3 WEEKS IN SCHOOL. YOUR AWESOME.!!!
Great to see you again Mr.Sorin love from Romania!
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
The legend is back again :)
As a DIY myself, this is one of my go to channel every time I had problem with my home repairs. Good work sir.
1h of skill and good vibes 😎 greetings from Germany
So happy that you are back. I am watching your video's for couple weeks and yesterday I repaired my first dead laptop. Thank you so much!
nice to hear from you again mr. sorin
You are a master
I like the way how you share everything without hiding the information instead of selling it
Thank you
I am glad to see you again Mr. Sorin, greetings from Bulgaria.
You're great.
I would like to stay by the side of the LEGEND and absorb directly all this knowledge. Thank you for your time making these videos Mr. Sorin. I would like to have a teacher like you, or work with someone like you.
nice to see u again >> miss u BOSS
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
I thought the very same thing and was about to ask on discord server and saw your comment.
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.
@@Dmiliunas I'm glad you have the same opinion and knowledge

One of your student from Nigeria, I'm inspired with all your lesson thank you sir.
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!!
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.
You ain't gonna die please...
That's too negative to say..
Where are you from ? Hope you don't mind chatting me up?
Hey how are you doing, buddy?
u good?
Did you die?
Im a frustrated technician....way back 1994 i work as a technician.. now after watching u sir, dont even say what i want to say..im speechless...just wanna say thank you sir...from the philippines...
Thank you and welcome back Mr Sorin, watching from Davao city Phillipines. Stay safe.
I was watching old videos from you again as am entering the try to fix ground as hobby. Love to see you back
you are really the best teacher
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 am from egypt
Good follower since a year
Wating for complete labtop repair course from a to z with pen ,paper and schematics followed by some measurements on real motherboards..
I know it'll take long time but you will be the best
sorin you are a great man and teacher keep it up. thank you from philippines.
Our teacher and instructor is back, welcome sir,
Good to see you back Sorin!
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 😁
We use this low side mosfets always as a diode.. check buck converters
Thank you for being a good teacher!🙏😘
Nice repairing chanel and you're my best youtuber 👍
This guy has magic in his hands. 👌👌👍
Your a generous man and a great teacher, thank you
Wow don't think I understood most of what you said I'm still basic but have learned so much from you and in time I will understand this to thank you ☺️
someone with the money should buy thermal camera for this guy as a thank you gift for the service he is giving us for free all those years...
from the end of the world|
Saw the repair sticker and found this repair shop is literally so close to where I live! That is amazing!
Where is it?
The great Sorin is back!
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.
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.
Thanks Sorin for all you do for us, god bless you, keep you healthy and away from harm
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.
You always remove chips and components so quickly and with precision !
I didnt notice i spent an hour on this video lol. Very informative
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 😍😇🙏🏽☝🏽💻
This is going on to my saved videos.
This one was a pretty good lesson Sorin
Thanks so much mr Sorin
Always a pleasure watching your brain at work
27:52 Sits back, says "this is a nice laptop", and smoke a Bob... I like this guy
Sir please make a full video about shorting on circuits on the laptop repair section to explain because a very well experienced person like you teaching methods is different from others really awesome
Great job and thx a lot, very calm and relaxing explanation on many things..love from Bosnia and Herzegowina
Excellent, second video i watch from your channel, u will have a subscriber from Colombia living in Bolivia Country, thanks!
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
I always learn something new everytime I listen to you. Thanks
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.
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.
unbelieveble patiance and dedication. Good job
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
looking forward to buying some tools as well bro
Pure black magic, Sorin removes a component the laptop works, it knows its master. G
Best wishes from Bulgaria!
Greetings from Poland 🇵🇱🙂
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.
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.
I thought that i knew something about motherboards and electronics, today i found out that i know nothing 😂🤦
Greetings from Poland👍
Hi from Greece ! Thanks for videos!
Good video!But i think here is a switching graphics and now the discrete is not working ,only that in cpu.
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.
You sure it is automaticaly can turn discrete to UMA ? I know the only way to change it with hand operation, changin some parts
You're a great person Mr. Sorin I learned a lot to you. Thanks a lot. Godbless you always.
Usually I use 3.3v as a voltage for current injection ( if the cap burns.. no way to fry something with a 19v voltage )
It is nice how you explain things and troubleshooting!
Best repair Chanel good luck master
This is a very important lesson Mr Sorin thank you
Very nice and informative .. your videos are very much educational for us ... Thanks for educating us.. God bless you
welcome back Sorin , again great vid like alway`s
The best electronic teacher
It looks like the short could have been caused by whatever was on the board and not the component. Maybe the FET is still good. That kind of looks like a splash of solder.
Thanks for posting despite the curveball at the end there haha. It was interesting and informative, regardless. Good seeing ya again.
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!
Good to see You Sorin !
When i see Sorin's video first i like then i watch...
Element14 have plenty in stock in the UK
Thank you Sorin so much for one more lesson.its amazing.i like the way you present the lesson to all the students in your class.
Iam a beginner and iam requesting ,if you can do a video for how to inject amps with power supply to find a sort circuit or faulty component.
Thanks..
Greetings from New Guinea.
Excellent, as always. Thanks for the video and knowledge...
Why don't you buy the chip from mouser, farnell o digikey?
Make sure you put back the screws in the right places!!! They have 2 different lengths. If you missplace it, a dent appears on the front of the laptop. The owner already did this once, you can see a small bump just below the trackpad. As a second comment, could it be working because the laptop is using the integrated GPU and didn't need the discrete GPU yet? Anyways, nice find of the culprit and a very good diagnosing lesson! Thank you.
i think it working fine tough it will act weird as it gets more balasted so it will need an extra power from that line anyway good vid thanks for taking me along 👍😀👍
Yeah, thats is what I recon is gonna happen.
31:12 time very good ... can you explain better? When you measure the resistance to plus ? And not to minus ? You said that is hight side mosfet shorted .... because that... thanks...
@glyn hodges thanks
From Kenya,great video
Sorin is the best
Great Work! I request you to make a video on how we can diagnose the problem in motherboard with the help of voltage fluctuation in multimeter. For instance if there is short on power supply of 3v section how we will come to know on multimeter or for instance if there is short circuit on 5v section then how we can come to know on Multimeter. Thank you
i love you Respect from algeria 🕊️
always cool mr.sorin , when you host your show ..love it
Love your videos and thanks for teaching. Often you reach a conclusion without explaining how you worked it out. So when there was no voltage at the charging port how did you know the charging port wasn't the problem and hence to check for motherboard short? How did you know the charger wasn't bad when there was no voltage on the charger?
Very nice explanation of power bus . Thanks :)
Thanks so much Sorin.
I had one HP spectre 430 G5 in my repair shop last month, which the 19V rail 1st Mosfet got short (FDMC 4435BZ) after replacing the P channel FET one V-Core chip was getting hot. The computer now turns up but no display. the chip could not be found online.
@Sorin, I know it is 3 months later watching this video, but it was interesting. The MOSFET you are missing is very unusual. Leave it to Fairchild, the company of brainiac engineers who were the foundation of Silicon Valley, and started the semiconductor revolution. Looking at the data sheet, the same time you were looking it up, it is a 10 pin MOSFET. YES 10 pins( before we get into semantics, it is actually 10 contact points). Pin 9 (GND), and The High Side Drain HSD, Pin 10 are on the bottom side of the chip! The HSD is also connected to Pins 3 and 4.
Love you from Uganda
Great video, nice explanantions... thank's Sorin 🙂
Bravo Sorine foarte educativ super tare!!!!!
Great to see you again
Am an apprentice but I stopped going to the shop because of your nice lessons and am doing a lot on my own now. Thanks so much sir.
One thing I don't understand and I wish to get help in is how you identify and disconnect certain parts of TV boards and it still works. How can I know how to disconnect this parts how do I follow the links to know?
Maybe feedback is for balancing load on all mosfets. If one is missing power management chip rises load on other mosfets
This is great.thanks Sorin
9:59 You had some sparks going on there. Lol. Still have the battery plugged in.
