Product: Pavilion
Operating System: Microsoft Windows 10 (64-bit)

I have an HP Pavilion - only a few years old.

When powered off and plugged in, the battery charges.

When powered on and plugged in ... it shows as connected to power on the task bar - however it runs from the battery and the charge is *not* maintained by being plugged in.

It discharges and the laptop shuts down when the battery charge hits zero (still while plugged in).

 

NB: Both the battery and the charger have been replaced with authentic HP spares - and the issue persists.

 

If I remove the battery, wait a minute or so, reconnect it, plug it back in and power it on - it all seems to work fine for a short time (20 minutes or so). Actually charges the battery while powered on. 

However then it stops charging - and runs from battery again until it fully discharges.

 

Any ideas?
