Description Leonid Podolny 2009-12-05 14:16:32 UTC

+++ This bug was initially created as a clone of Bug #12187 +++

Latest working kernel version:2.6.31
Earliest failing kernel version:2.6.32
Distribution: Gentoo
Hardware Environment: MSI PR200
Software Environment:
Problem Description:

Some time after booting the laptop the system stops seeing the battery charge state.
The problem also appeared in kernels prior to 2.6.31, but it appeared so rarely (days after booting) that I can't really say what was the last kernel when it worked OK. In 2.6.32 it is wrong right after boot.

For example, with fully charged battery and power cable connected:

leonid@looptop ~ % cat /proc/acpi/battery/BAT1/state
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            unknown
remaining capacity:      unknown
present voltage:         10000 mV
leonid@looptop ~ % cat /sys/class/power_supply/BAT1/charge_now
-1000

This bug is actually a duplicate of B14446 -- it started working after I applied a patch from there.
