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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1098697 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: http://www.divnut.com/HP_ENVY6_1006sa/HP_ENVY_6_48hr_discharge_2012-12-08.png The gradient looks OK, so nothing wrong with the battery. Left a further 48 hrs and the Sleekbook would not start on battery alone. http://www.divnut.com/Ubuntu/HP_ENVY_6_96hr_discharge_2012-12-10.png 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 http://www.divnut.com/HP_ENVY6_1006sa/Battery_check_281212_15pm26.png Conclude its a Ubuntu kernel issue?
