My computer has suddenly hibernated itself when I am using it on battery. When turning it back on, Windows said that it hibernated due to the battery reaching critical levels. However, when I turn it on, the battery has 40% plus battery capacity left. Has anyone else had this problem? Is it a bad battery? I has happened about 3 times already.

I have a similar problem with my T500 although not to the same degree, the batter guage appears to be off in my own one by 10% so when it was at 15% it suddenly went into hibernation, difference was when I started it back up it said 5% so maybe a different problem.
I am currently doing a battery guage reset to see if that corrects it.
It could be a bad battery, however what is the condition reported in the power manager? -
what is the value of actual and design charge capacity on your battery (check under Thinkvantage Power Manager's battery section in advanced mode).
Also, did you update the battery firmware? -
Power Manager 3.30
Did not update battery firmware.
Remaining Capacity 52.33 Wh
Full charge Capacity 56.20 Wh
Cycle Count: 20
FRU part number: 42T4791
Sanyo
Manufacture Date: 2010-06-07
Design Capacity 56.16 Wh
Would updating the battery firmware fix this problem? -
Doesn't hurt to try, but I think that firmware update only updates the older batteries. Like it only updated my auxiliary 6-cell battery that I believe came from an SL410 in August 2009. I own a T410 with a 9-cell that I bought with the laptop, and a 9-cell seconary. It didn't update either of those as it said it didn't apply.
Otherwise, I'd try doing a recalibrate in Power Manager.
Also, you sure your laptop isn't set to hibernate in the power savings settings at some silly high percentage? -

Well your full charge capacity is higher than the design capacity which is a bit odd know?
I reset the battery guage and have found that my new capacity is 80Wh instead of 84 which is the design. I am pretty sure that is caused by when it was drained completely as I hibernated it but had that vista issue where it doesn't shut down properly due to the LAN I believe.
Have you let your battery drain completely before now? -
Sorry, the full charge capacity is 56.10 Wh. Just had a typo.
I did not try updating the battery firmware because it is not part of the affect list.
Maybe I'll call Lenovo and see if a replacement battery helps.
Any recommendation on the brand? Sanyo, Panasonic, Sony, LG? -
I haven't experienced anything like this though. Sounds like a dud battery to me, but what's the harm in trying the firmware update?
