Power Management problem when battery charge level is critically low

[Sergio Belkin]

On Ubuntu Hardy Heron, I have a problem:
When my laptop (Lenovo 3000 C200 8922 A15) reaches a critical low
level of battery, system doesn't shutdown cleanly, so after power on
again, I have to wait to fsck make its task. That's is too annoying. I
don't understand if it's a powernowd problem. So I enabled
laptop-mode, but it's not working, this the current
/etc/laptop-mode/laptop-mode.conf,:
