I had problems with my HP test laptop, would run on mains power ok but not charge.  After some searching I found an answer on an HP forum (and it appears applies to multiple O/S).

The answer that worked for me was to uninstall all the ACPI drivers, power down the laptop, remove the power lead and battery, leave it a couple of minutes, plug in the power (leave battery out), boot system, shut down system, put battery back in then boot as normal.
