I used this site to disable WOL before shutdown: http://www.hecticgeek.com/2012/09/disabling-wake-on-lan-in-ubuntu-might- save-a-tiny-bit-of-power-on-your-laptop/
This did not work. I lose about 1% battery an hour when shutting the machine down from Linux. WOL is off in UEFI, and Windows shutdown works the way it should. My machine uses a Radeon R9 M265X graphics chip, so I'm not sure it's only a video driver issue. -- 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/1479322 Title: Acer Aspire M5 481T consuming power while turned off! Battery drains with system halted! Status in linux package in Ubuntu: Confirmed Bug description: Guys, I'm facing this problem just since I installed Ubuntu 15.04. The laptop came with Windows 8 installed and this problem didn't exists there. Everything seems to run just fine, but when I turn it off with 50% of battery for instance there is no energy after some hours and I can feel that the laptop is a little hot, but there is no noise like anything was on.. What could be happening? I've searched for some solution, already tried to include some options in grub config like noapic, nolapic, irqpoll, acpi=off and others without solution. Also tried to check WOL but it's ok too. What could be happening? How to solve this problem?
