Description of problem:  g-p-m does not correctly calculate the remaining charge of a laptop battery, or does not correctly calculate the capacity of the battery.

Version-Release number of selected component (if applicable):
gnome-power-manager-2.25.1-2.fc11.i386

How reproducible:
Always.

Additional info:
g-p-m is giving the following problems:
1) I receive warnings saying that my battery has a capacity of 0% and is either old or broken. Yet it is not, since it was only since the last update to 2.25 that I have received this error (and I have since run for over an hour without AC power);

2) The g-p-m icon reports "Laptop Battery Fully Charged (nan%)", or, when running off battery power, "Laptop Battery Discharging (nan%)". There is no indication of how much charge is truly left in the battery (I'm guessing this percentage calculation must have a division by zero error?);

3) I no longer have a "Hibernate" option in my shutdown box;

4) It no longer responds when I unplug the power cord. I need to restart the computer for it to realise that it is now running on battery power.
