TDEPowersave always reports running on AC power, even when running on the battery, and doesn't give the low battery warnings. This started when I upgraded to R14; it worked fine in 13.2. It's a big problem because, when runing on battery, the machine just dies with no warning when the battery is dead.
This is on an HP laptop running Debian 7 (Wheezy) and R14 from Slavek's repo, updated this morning.
