Well, I was only responding to someone else who had the problem. I've experienced it once though. I was on a plane and discharged a battery until the computer auto-suspended. I replaced it with my second battery and ran that to about 20%. When I got home, I completely charged the second battery. I then popped in the first battery to charge it and was surprised to see 100%. I turned it off and back on and it still said 100%. Furthermore, it wasn't charging. I was certain I had only charged the second battery, but just to be sure I popped it in. 100%, and I had only had time to charge one battery so I knew the first battery was still discharged. I put the first battery back in (still saying 100%) and let the computer sit. It seemed to be discharging as if full, then 10 minutes later it went from 3:02 left to 0:00 and suspended. After that, it recharged normally and I haven't had the problem again. Since it's possible for the battery to say 100% when it isn't really at 100%, that might account for why it seems to die with 30+% or an hour left. For some reason it thinks it's reached 100% charge when it's only at 70%. That stops the battery from charging futher. Then when discharging it estimates time from 100%, meaning the battery is drained when the computer thinks there's 30% left. I'm rather curious how the computer comes up with these numbers. -- John H.
