I have same problem with same model.
Charging ok, 3v and 5v ok.
I don't it ia BIOS problem, but I guess problem is SIO or ICH.

Voltage on power button drops to 0.5v and 3.3v comes back with no system effect.

It would be great if somebody confirms.

In this new laptop,

1. what voltage do you get at pin6 of U6000?
2. voltage at pin4 of U6000?
3. R6018 if open or high resistance?
