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
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 :)
nice to hear from you again mr. sorin
As a DIY myself, this is one of my go to channel every time I had problem with my home repairs. Good work sir.
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 see u again >> miss u BOSS
I was watching old videos from you again as am entering the try to fix ground as hobby. Love to see you back
Good to see you back Sorin!
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

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.
1h of skill and good vibes 😎 greetings from Germany
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.
One of your student from Nigeria, I'm inspired with all your lesson thank you sir.
You always remove chips and components so quickly and with precision !
Best wishes from Bulgaria!
unbelieveble patiance and dedication. Good job
Hi from Greece ! Thanks for videos!
Your a generous man and a great teacher, thank you
I always learn something new everytime I listen to you. Thanks
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.
Thank you and welcome back Mr Sorin, watching from Davao city Phillipines. Stay safe.
It is nice how you explain things and troubleshooting!
Good to see You Sorin !
You are a master
I like the way how you share everything without hiding the information instead of selling it
Thank you
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!!
Thanks so much mr Sorin
Always a pleasure watching your brain at work
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.
This is a very important lesson Mr Sorin thank you
Bravo Sorine foarte educativ super tare!!!!!
Thank you for being a good teacher!🙏😘
Excellent, as always. Thanks for the video and knowledge...
Our teacher and instructor is back, welcome sir,
Great job and thx a lot, very calm and relaxing explanation on many things..love from Bosnia and Herzegowina
The great Sorin is back!
sorin you are a great man and teacher keep it up. thank you from philippines.
You're a great person Mr. Sorin I learned a lot to you. Thanks a lot. Godbless you always.
Great to see you again
Thanks Sorin for all you do for us, god bless you, keep you healthy and away from harm
always cool mr.sorin , when you host your show ..love it
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 ☺️
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
This is going on to my saved videos.
This one was a pretty good lesson Sorin
Very nice explanation of power bus . Thanks :)
Very nice and informative .. your videos are very much educational for us ... Thanks for educating us.. God bless you
Saw the repair sticker and found this repair shop is literally so close to where I live! That is amazing!
Where is it?
you are really the best teacher
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 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
Nice repairing chanel and you're my best youtuber 👍
Great video, nice explanantions... thank's Sorin 🙂
Greetings from Poland👍
Thanks for posting despite the curveball at the end there haha. It was interesting and informative, regardless. Good seeing ya again.
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?

This is great.thanks Sorin
Excellent, second video i watch from your channel, u will have a subscriber from Colombia living in Bolivia Country, thanks!
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
I didnt notice i spent an hour on this video lol. Very informative
Hello hello master! Good. To see you again.
thank you,thank you and thank you. inspiration for me.
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 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.
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.
Best repair Chanel good luck master
Greetings from Poland 🇵🇱🙂
Really Hard video to do, and what a massive result in the end!
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.
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|
good video sorin!
thank you sir, great work
Thank you for videos 🙏🏼
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.
Great video
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.
27:52 Sits back, says "this is a nice laptop", and smoke a Bob... I like this guy
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.
When i see Sorin's video first i like then i watch...
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
Hy Sorin! it would be great if the "shop workflow" series continued.
Another great video
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?
Great work.....
You did a great job :)
Great 👍, ... love from Aden
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.
The best electronic teacher
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 😍😇🙏🏽☝🏽💻
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
Usually I use 3.3v as a voltage for current injection ( if the cap burns.. no way to fry something with a 19v voltage )
Superb video sir thank you ❤👌
Well done Detective Sorin . ; - )
Thank you!
Thank You for your lessons :-)
