Battery management in Fedora?

Hi I'm using Fedora 8 and my battery is always fully charged to 100% which is not a good thing when I mostly plug my thinkpad in AC mode. Is there the Power Management software for Unix like the one in Windows provided by IBM? If not then is there anyway to restrict how much charge I can control for the battery in Fedora 8?

Thanks

Haven't found one. I control charging by physically removing the battery.

TP Smapi works well on Fedora (haven't tried on F8 but should work). Install first kernel-devel (yum install kernel-devel or something like that) and then just compile the smapi kernel module. then try it by loading tp_smapi modulle (modprobe tp_smapi). There is a page on think wiki that explain how to set battery charging tresholds... Works fine for me in F7...

Well on my machine (T40), it loads, and there's stuff in sysfs, but setting start_threshold or stop_threshold doesn't seem to do anything.

I wrote the following lines in my /etc/rc.local and it works fine for me... What does not work for you ?

#TP Smapi battery tresholds
echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
echo 70 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

Running those does not do anything. Well I haven't tested the start threshold, but the stop threshold definitely is not doing anything.

Try tu put these line in your /etc/rc.local and reboot... It should be working if tp_smapi is loaded....
