Anyone who has ever used a notebook or netbook computer understands that battery charge percentage reporting is not even near an exact science. If your notebooks and netbooks are like the ones I’ve used over the years, you’ve probably found your notebook or netbook completely shuts down way before your battery charge gets to 0%. I’ve had some units that failed with a charge over 20% and power management set not to do anything at that relatively high level. So, imagine my surprise when my Acer Aspire One running Ubuntu 9.04 Netbook Remix kept running about 20 minutes after the battery charge indicator hit 0% (see screenshot above).

I spent quite a bit of time learning about how UNR manages battery power on my Aspire One. And, I’ll be sharing that both here and over on MobileContentToday over the next few days.
