Power lekunda panichestundhaa,e battery charging cheyyala.

The question is to reduce voltage from..19v to. 5v 3.3v. Or 3v why don't we use simple ragulator or resistors??

You are a good master, thank you very much sir

@Pavithralaptopcare I'm curious... What about case where 3VALW is shorted by lower mosfet and bios got corrupted(SPI chip containes garbage data) and after solving both problems pc turns on by itlself and shuts off right away in a loop? Is that also faulty PCH or can be sth else?

Thank you so much man, the video was so informative!

Good video. But whats the difference of Boost capacitor in PWM section. Here volt increase toward DC side , but in PWM towards AC side. Why?

Hello, same here the sd card board was the issue, clean the oxydation with flux and reflow both capacitor and realtek chip. Quivk diagnose, turn on, it make beep , unplug the flzx between motherbard and the sd card board, and the beep sound disappear.

👍👍👍👍
