[Bug 1098697] Re: High Battery discharge rate when Laptop is off.
I have Toshiba L755-1DR laptop and Ubuntu 12.04 64bit. I had battery
drain and it seems that disabeling "sleep and charge" in the bios fixed
it. I don't get battery drain anymore.
"Sleep and charge" gives power to one of the usb ports while the laptop
is off. I never had anything connected to the laptop while it was off,
so I guess the usb port leaks the power somewhere.

Title:
High Battery discharge rate when Laptop is off.
Status in “linux” package in Ubuntu:
Confirmed
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?
