Hello, wondering if someone knows what's wrong.
This problem occurred recently:

The laptop runs on ac without the battery just fine.

If I boot up the laptop with ac and battery installed, only the battery is detected, then removing the battery and just using ac the laptop won't boot. Turning the psu off and on it boots.
So it seems the psu shuts itself off when connected to the laptop with the battery installed.

Is this a battery or psu problem? or motherboard ?
Help appreciated
