Comment 23 for bug 127773

I am also having this problem on a Thinkpad Z60t. It worked fine until I restarted a service, and now doesn't recognize the battery at all.
I appears however:

zachary@ibm-2513:~$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: charged
present rate: 0 mW
remaining capacity: 63640 mWh
present voltage: 12439 mV

This is all true information, and doesn't seem to be making it's way to the Gnome-Power-Manager, which as someone mentioned before is a most likely a hal issue
