Comment 3 for bug 633552

I tried matching the heuristics up with this properly, there are conditions where there's no time remaining and only a percentage, gnome power manager is supposed to take data of the percentage over time and estimate the time remaining, so in theory the time remaining would eventually be updated, hence why it says estimating.

The problem seems to be that some laptops don't make the estimation easy somewhere deeper inside of the code.

I'll try and improve the situation somehow
