Powers supply / chargers isn't the issue.
It wont turn on from battery when button is pressed.

Please read and try to understand the issue first.

Hi guys,

I have pretty much just finished repairing this laptop after 3v rail shorted around 8 components.
Now I have the machine booted up with all voltages present.
Display etc etc works, I can get to BIOS without issues.

BUT - the problem is this.

Battery connected and is healthy. Wont turn on unless charger is connected.
Then I can remove the charger and it will continue to run from battery.

But if I turn off the laptop, it wont boot from battery. Have to stick in the charger again to trigger it.
All MOSFETs are good,...
