I have this bag with 3.5.0-36-generic. Everytung is O'K on AC power, but my Acer 5750 hangs within 30 min on battery power.

It was rock-solid on both AC power and battery power before upgrading to 3.2.0-12. It remains fine on AC power. I believe the battery in the system to be healthy - it is relatively new and holds a 3hr charge. The other hardware seems fine too, and given that the freezes started after a kernel upgrade I suspect a software (power management?) problem rather than a hardware problem. To reproduce: 1) Unplug from AC power 2) Wait 2-30mins Symptoms of the freeze include: * Mouse is frozen * Internal keyboard is unresponsive; can't switch to a VT either * USB devices plugged in after the freeze do not get powered on * Network connections dropped; the machine doesn't respond to ping after the freeze I haven't seen anything in syslog that I can attribute to the freezes.
