[Mactel-linux-users] battery status sometimes lost after suspend

[Mildred Ki'L. <ml....@on...>]

Hi,

Since several days, I have regularly some problems with the battery
status (the little thing that tells me if my battery is full or near
empty). At boot it works just well. Sometimes, after suspend, the
information is lost (so I don't know the battery level).

The kernel just says 0:

$ cat /proc/acpi/battery/BAT0/state                                                                                    ~
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            0 mW
remaining capacity:      0 mWh
present voltage:         0 mV


I haven't made extensive tests for now, so it's just some introductory
message and I want to know if someone else have similar problems. I
suspect some of these may have an effect:
- very long suspend time (I juwt woke up my laptop from 24h of sleep
  and I just noticed again the problem)
- if the state of the power has changed during the sleep (example,
  the laptop was charging before sleeping and I plugged the power cord
  before it woke up, or during the sleep, it has been charged but the
  power wasn't present both at sleep time and wakeup time or other
  strange combinaison)

Until now, I assumed that to fix it I had to reboot under Mac OS X to
reset the battery state, I know it works but i haven't recently tested
if just normal reboot from linux to linux is enough or not ... have to
test again.

My linux kernel:

$ uname -a
Linux kylae 2.6.27-ARCH #1 SMP PREEMPT Sun Oct 12 15:16:25 CEST 2008
i686 Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz GenuineIntel GNU/Linux

My laptop: MacBook2,1
