FC12 battery information

[Robert Moskowitz]

I just got a BIG 9 cell battery for my HP nc2400.  Before I had an old 3 
cell battery that was only good for 1 hr.

So the system is charging and Fedora is reporting the battery is 100% 
charge.

The battery info is now reading 70.3 Wh with a design charge of 12.7 Wh 
(the old battery was labeled at 28Wh, but it was old).  The spec for 
this battery is ~84Wh.

What does it take to get FC to reread the battery info from the battery? 
  Oh, the system was in hibernation when I inserted the new battery.  I 
let the battery charge for ~20min before turning it on.
