Details

Description: Since a recent reboot (I had updated from 3.17.something to 3.18.something before), my laptop battery is no longer detected correctly.

acpitool -B (via aur) gave

Remaining capacity : 43110000, 100.0%
Design capacity : 0
Last full capacity : 0, -1.000% of design capacity
Capacity loss : 101.0%
Present rate : 0

Altough being connected to power for several hours before, my laptop will switch off immediately when plugging the powercord.
After that, I cannot normally turn it back on for some reason, I have to first remove the battery, then plug the cord back in and then re-insert the battery.
This is all very strange and did not happen before recent reboot.

linux 3.18.6-1
acpitool 0.5.1-6

I attached dmesg log just in case.
