Amazing thinker! Even that I am not an electronic technician myself (just able to fix the very simple issues with my and my friends home computers, not at the motherboard component level of course), I still love to watch how he demonstrates his way of making logical conclusions. Also his opinions on the general subjects and the way he expresses his point are just brilliant! Great respect to this guy and thank you. Sorry for my English...
I am starting in component-level motherboard repair. I found in one of my own laptops almost the same issue (core vcc is not shorted but both coils that feed the cpu doesn't receive any voltage, MAX8770 is not giving the signal to the mosfet...) I can't believe I stepped into this video
I don't understand why someone would troll about mosfet/transistor. The last letter in mosfet is transistor. By definition a transistor can be used to amplify or switch.
One of my old laptops broke recently, and i tried to recover the harddrive and failed but even before it seemed that the integrated graphics was locked to a lower frequency despite no heat problems. When i took it apart it seemed some mosfets had come out from drops. How would i go about fixing this?
I have problem with semince pc hmi the core voltage is 0. 977 v. The mother board dosnt boot after i off and on the hmi unit the unit start boot and cpu voltage core becom 1.074 vand the unit work ok but after half hour the hmii freeze and back to mesur the voltage return to .0.977 please help me which point to check. Romany from egypt autmotion manger Note: found two smd ccapcitore has over heated i remove it but dont install new one is ther about 30 cpictor
I am facing a problem of overheating with the processor vcc coil, knowing that the device is working and there is a slow performance, in your opinion what is the problem? The mosfets and control ic have been changed
My desktop motherboard (ASUS M5A99FX PRO R2.0 rev. 1.01) has 16 of those mosfets! Replacing them all would be a bitch. How would I test which is bad? Half of them are 4937N, and the other half 4955n. There's more code after that but I think only these first parts matter? The VRM chip on the board is an ASP1000C. Am I at least getting the numbers right? Got this dead board with a CPU related issue (CPU_LED lit, not booting) and am trying to figure out board repair for the first time. CPU itself is good, but I'm reading all kinds of shorts to ground with the multimeter on beep mode, including both pins of all the capacitors by the inductors right next to all those mosfets. Any hints or pointers? I'm just theory crafting right now tho, don't even have a hot air gun yet.
If my electronics teacher took a look at a broken macbook, he would say that it doesn't work because vcore doesn't have 3.3 volts on it. Well, at least he knows that there transistors inside PCs today.....

2 years later and your editing style and knowledge has held up, thank you!
Some good tips - thanks Louis!
You are the Top of the Top louis, thanks a lot Man
Very instructive - thank You ;)
Oldie but a goodie. A great reference video for Vcore problems
Thanks dude, very good videos.
Thank you as always.
very interesting Thanks so much !!! learned more about macbook pros this week alone than all my 36 years on this earth.
Well explained thanks again
I'm impressed. Now you have another subscriber.
Thanks again and again

Love the way you ended the video. "Isn't that a pretty sound" 😊

Excellent! Maybe you could shorten the explanations, as they sometimes are a little repetitive, but I like your style. So everything is okay

i've learn it fixing power suplies
