In the meantime I had the opportunity to test this on another HP Folio 13-2000 which is running Windows 7. The user wasn't affected by this bug only because the default settings for 'critical battery level' were set to 5 percent – so when the battery reached 5 percent the notebook would be sent into hibernation.
When I changed this setting to 2 percent (in Windows 7) I was able to reproduce this bug. So this really seems to be a firmware bug and not a kernel bug. I'm in contact with the Hewlett Packard support now and hope that they will fix their BIOS. I'm going to keep the UPower bug open since UPower still fails to update the status of the AC adapter but I'm going to close this bug since it seems to be the BIOS which is responsible for the reported inaccurate battery levels – not the kernel. Thank you very much for your help! Stefan. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
