Comment 39 for bug 1088146

I don't think this bug is related to the battery or even the upower package.

There is something non-volatile about this computer that only disappears when all power is removed. Not even a reboot fixes the problem. Maybe a BIOS problem, I don't know...

I'm trying several things to identify the source of the problem. One of those things requires some changes in the BIOS settings, but I'm not sharing them yet because it may brake something. Please don't mess with your BIOS.

There is one test that I challenge everyone to try: Boot the live cd of Ubuntu 13.10 (Saucy Salamander) several times.
This version is powered by kernel 3.10 and includes some fixes to this laptop. The display dimmer finally works out of the box. I haven't investigated very much about what else works out of the box with this version, but I noticed that all boots worked flawlessly. 32bit image is here: http://cdimage.ubuntu.com/daily-live/current/saucy-desktop-i386.iso

Anyone here is using Ubuntu 32 bit? You can check it with this command: uname -i
