I'm running Dapper 6.06 LTS...
It's odd that my power managment icon showed up in the status bar of my
laptop until my last reboot, and now it no longer shows at all.  But,
when it was there, it seemed to work ok, except that I had to mouse over
it to know (in text) how much power was left on the battery.  It didn't
seem to be that accurate, though.  At one point, mousing over would say
"you have 3 hours 45 minutes of power left"... and then, 5 minutes later
- "you have 2 hours 12 minutes of power left"... and then, 10 minutes
later - "You have 3 hours 58 minutes of power left"...
