Hello!
I'm a new user here. I wish I can collaborate in the future and not only seek advice. I revive this thread as it is the exact model I have and I've downloaded the schematics. Huge Thanks for that!
My laptop is 99.9% dead: When I plug the AC cable the LED turns white for a few ms then goes out.
If I press the power button, the LED turns amber for as long as I keep the button pressed.
Below are my voltages with the AC charger plugged in, the only 'weird' value is 19V_DCBATTOUT which is around 17V.
Other tests I've done:
ACOK pin is 3.3V
Nothing gets hot on the thermal camera, just the ISL9538C increases a couple of degrees when pressing the power button but I can't see anything else of relevance.
BIOS chips, U2501 and U2503. They get 3.3V VCC voltage. But I don't see any SPI activity (SCK, DI, DO, CS) even when I press the power button.
Is my CPU dead, doctor?
