[Bug 1098697] Re: [HP ENVY Sleekbook 6-1006sa] High Battery discharge rate when Laptop is off.


So, this issue has been downgraded to Low importance and the status
changed to Incomplete because somebody has noticed that Dave is not
running the latest version of the BIOS on his HP ENVY laptop.

This is a generic problem affecting all makes of laptop. The BIOS on my
Toshiba Tecra M2 does not support the "Sleep and Charge" feature, so
that's not what's causing the battery drain. Let's remind ourselves that
this problem did not exist until a kernal update caused it to happen
with all flavours of Linux. It does not exist when Windows is the
operating system. We do not seem to be getting any closer to the root of
the problem.

  [HP ENVY Sleekbook 6-1006sa] 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
