Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

The power button doesn't work, all three LEDs on the keyboard are lit up (but the power LED isn't), the whole system seems to be off but frozen in a state where it cannot be turned on again. It seems that the Linux kernel (or some utility) puts the system's BIOS into a state out of which it cannot recover. I have tried to narrow this problem down to the hibernation process (and not some other utility running before or after hibernation) by editing `/etc/acpi/powerbtn.sh` and replacing its contents with sudo pm-hibernate exit 0 so I know it is actually running the hibernation process when I press the power button. And every now and then it actually works, but just as often I have to kill the BIOS battery. I have looked for a newer BIOS version (just in case it's the mainboards power management going berserk) but I seem to already have much newer versions than available at http://www.asrock.com/nettop/overview.asp?Model=ION%20330&cat=Download&os=BIOS, where the newest version is from 9/7/2009: $ sudo dmidecode ... BIOS Information Vendor: American Megatrends Inc. Version: P1.10 Release Date: 11/24/2009 ... I have tried replacing the `nvidia` GPU driver with the OSS `nouveau` driver, but the problem still occurs. Any help further narrow down the cause of this bug would be appreciated. Thank you!
