Evidently, /sys/class/power_supply/ADP1/online always contains the same value. Interestingly enough, though, if the box is suspended to RAM and resumed, the status of the AC adapter is correctly updated, but the value read at that time remains in /sys/class/power_supply/ADP1/online until the next suspend/resume cycle regardless of what's going on with the AC adapter. 2.6.27.7 works correctly on this box so the recent EC patches don't seem to cause this regression to happen. Any other ideas? Rafael
