Hi,
So i have this Asus G17 2023 which power on normally but there is no power led ON nor keyboard working.
There is 3.3 volt on power button and 5.1v on the keyboard.
THe charger led is working too.
Can you direct me what to check for that power led which i suspect is the reason why all other are not working....

Re: Component blow up, Asus GL704
update:
so, after injecting 1v2amps, i got the PCH heating up, so its shorted...
replacing PCH is it doable? with heat gun?Leave a comment:

Re: Component blow up, Asus GL704
thx, but after checking its not that chip, its th 822 resistor that goes hot,
after further inspection, desoldered the TPS51258a and injecting 19v found a Mosfet (PE616BA) pulsing which is connected to 3.3 rails, inspected it and its shorted to ground.
so i did inject 1v1A in that coil, the voltage drops to 0 with 1amps is drained but no heating present,
do i Increase the amps?Leave a comment:

Re: Component blow up, Asus GL704
hi all,
so i Soldered the RT8819A IC now no short in 5v rail but im back to the first problem which is the TPS51258a getting very hot when 19v is present.
so when I inject 19v 1amps, in the 19v main rail that chip heat up, but when I inject less than 1amps (500mA) the chip is pulsing, i observe it with IR cam it, but I have a 6 pin chip with marking 8KB RX (RX is vertical) heat a little.
can you help me identify this chip?
pic attached.

Re: Component blow up, Asus GL704
Update:
Removed the RT8819A IC, now im getting high resistance to ground and when i inject 1v there is no amps drain, ordered couple of IC, will update when they arrive, in meanwhile i will practice my QFN soldering.

Re: Component blow up, Asus GL704
Thx for reply
Im already doing what you suggesting, already fixed a 1070GTX MSI , was water damaged, did some mistakes burned some 0Ohm resistors and tracer but in the end managed to fix it.
but this laptop is making me crazy, no diagram no schematics, Im advancing with your help...
