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. -- 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: [HP ENVY Sleekbook 6-1006sa] High Battery discharge rate when Laptop is off. Status in “linux” package in Ubuntu: Incomplete 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.
