I am running crunchbang (#!) linux on my netbook (which uses an ubuntu core).
When I start my netbook (running on battery) I am prompted to reset my Bios settings. This causes some problems with my clock, since it is reset to factory default settings. Which in turn causes problems with fsck and my OS doesn't boot properly on normal mode.
What I did so far was loading the OS in recovery mode, letting fsck fix some timestamps in manual mode and eventually it will let me through to the OS. Logged in I updated my clock and I don't get other errors.
The strange thing is that if my laptop is plugged into AC (not using the battery) and I in a previous session had updated the clock and all, it wouldn't prompt me to reset the Bios settings. But as soon as I boot it from battery it prompts me again. Which could mean it is a hardware problem. Some capacitors leaking power. But it is only on start up, I don't have strange drift rates or jumps in my clock after I updated it manually with a server.
I am unsure what causes my problem, whether it might be simply a hardware failure or due to some bug in my OS. Has anyone experienced the same problem?
