You are actually timing how long until it automatically shuts down due to running out of charge, not just going from the estimated time remaining, right? Those estimations aren't reliable with old batteries. > I'm left wondering: > 1. could a fifteen your old battery still have 80% capacity? Discharge/recharge cycles are quoted as the key factor for battery aging, so it might fit if the battery was never used much. > 2. should a new 4400 mAh battery last more than 4.5 hours? Was the screen on/off for both the old "little over one hour" test and the new tests? I don't know what's normal for a T400s, but details like that and whether you were using it or just letting it sit would be important for getting a real answer. -- __ __ #_ < |\| |< _#
