It's isn't a very debian-specific question, but the os on the pc is debian:P
I just want to ask, that what could be the problem, when after shutdown, it doesn't start? The fans doesn't start, no nothing, i have maybe some clues: i installed before lm-sensors, and it wrote "ALARM" for some voltage values [about ~6 alarm captionsxD from the ~10] so... i don't have a backup psu, but i think that could be the problem.
what else could it be?
ps.: i could bring the pc to life, when i take out the bios battery for a few minutes:O so i'm not 100% sure that the psu is bad:S
