As I remember, I have this bug on my HP ENVY DV7 on all linux systems,
from Fedora to Debian, independently of installed Desktop Environment. I
have also preinstalled Windows 8 with no such effect. It's really

  High Battery discharge rate when Laptop is off.

Status in “linux” package in Ubuntu:

Bug description:
  I have a HP ENVY 6 1006sa Sleekbook running Ubuntu 12.10. Fully
  charged, unplugged Mains adaptor powered down. 48hrs later re-powered
  charge now only 65% ! The Laptop battery is discharging when the
  Laptop is powered off:


  The gradient looks OK, so nothing wrong with the battery. Left a
  further 48 hrs and the Sleekbook would not start on battery alone.


  While my Sleekbook is in warranty I'm dual booting Win 7 and Ubuntu
  12.10 (Unity desktop). I've done a  Win 7 and Ubuntu 12.10 battery
  drain 'when off' comparison:

  Win7: 4% per 24hrs ,
  Ubuntu 12.10: ~17% per 24hrs.
  (The measurement includes power on and boot to OS to make the measurement)

  Did a longer Win 7 test for improved accuracy:  10% depletion in 7.5
  days or 1.3% in 24hrs.

  Updated the Sleekbook BIOS from F.04 to the latest F.12 – No Change.

  Did a Win7 HP Battery diagnostics check: OK


  Conclude its a Ubuntu kernel issue?
