Thanks... This did the trick... Need to replace the keyboard then......

Hello, I am trobleshooting a laptop and I need to find the KB pins to short to power on the laptop - power button not currently working.

I got Acer Aspire A715-42G, no 19v going through the DC-IN mosfet. I also checked the components/power rails downstream and no short detected (gpu and cpu rails are at 2-10 ohms)
I have checked that there's no gate voltage on the DC-IN mosfet, so I checked if PUB1 has power.
Turns out there's no 19v going into PUB1 VCC caused by a burnt 10 ohm resistor (PRB12 - 19v stops here).
Replaced the part but it burned when I plugged in the charger - telling me there's something pulling high current.
I checked the resistance of PCB16 and it was fine.

I measured the resistance...

Hello there,

Wins J. from Philippines - IT and currently automation engineer in a semiconductor company.
Somehow, I got pulled into fixing laptops at board level when a relative asks me to repair their laptop (their typical mindset - an IT can fix everything), and since then, I became interested in board level repairs.
I want to learn more advanced techniques and troubleshooting, and repairing electronics is more of my past-time activity though - not intended to make it a profession.
