Hey folks,
yesterday, I tried to fix some power saving issues that annoy me for quite a long time but I wasn't successful at all. Hopefully someone can help me to fix some power related problems:
(by the way, I'm using a Lenovo 3000 N200 laptop)
1. I use gnome-power-manager to monitor the remaining battery capacity. Unfortunately gnome-power-manager somehow lost it's feature to find out the discharging rate and therefore can't estimate the remaining battery time anymore. This leads to notifications that tell me in bold characters that they don't know anything at all.
2. Additionally, my laptop is not shutting done anymore when the remaining battery capacity becomes critical. I enabled the feature in gnome-power-preferences but it seems that it has no effect. I also use laptop-tools but I was not able to find a matching configuration option.
Is there anyone who can help me on that issues?

1) use "acpi", "yacpi" or similar applications.
2) use "sleepd-git".

acpi gives the following output:
Battery 0: Discharging, 40%, discharging at zero rate - will never fully discharge.

what about /proc/acpi/battery/BAT0/state?
maybe your battery is dying (check /proc/acpi/battery/BAT0/info). or you recently updated your kernel and there have been changes in the acpi module for your system.

[2beers@laptop ~]$ cat /proc/acpi/battery/BAT1/state
present: yes
capacity state: ok
charging state: discharging
present rate: 0 mA
remaining capacity: 1785 mAh
present voltage: 11100 mV
I think it may rather be a kernel module than a dying battery...

well, it worked before, didn't it? did you update the kernel in the meantime? if so, i suggest you roll back the kernel.

The problems with the battery discharging rate are quite old. I never got too annoyed to deal with them though. Since then there have been quite a lot new kernel versions, so downgrade is not really an option.
