I have a Lenovo T61 which I purchased in July of 2008. Two years later I still have the same battery ( a 9 Cell), I always leave it in the optimize battery life setting and almost always leave the computer pluged in. This week I used the computer sans the powercord and was getting roughly 2 and a half hours depending on my screen brightness. The next day I turned on my computer (again sans power cord) and the computer would not turn on not even for one second. So I plugged in the computer. It now lists the battery as 73% charged but as in poor condition. My computer will not remain on at all if the cord is removed. I am well aware that batteries lose power over time, however I find it incrediably suspcious that a battery would have a 2 and a half hour charge one day and then die the next day. Is there a way reboot the battery? Or at the very least can someone explain the massive one day detriaton of the battery?

Yes, my battery is a 42t4530 and was not recalled. As such Mark_Lenovo always relplies that one must by a new battery. What Mark never addressed from the posts I have read is: How can a battary go from a near 3 hour charge to 100% dead in less than 24 hours.
What I did find was this
Hi, I had purchased a T61 in May last year. I purchased extra battery to get more juice for my machine (the ones that protrude at the back). I had almost 5-6 hours of backup when the battery was new. I maintain my batteries well and till last week I had 4 hours of backup, but suddenly one morning the battery went dead. The indicator is blinking yellow and battery went from 4 hours to 0 in a single day. I checked with recall program tool, and I am not a part of it, but I am sure that something is wrong with my battery and it is not natural decay of the battery. I have tried unplugging and putting the battery back in. The power manager gives message "A battery error has occured" Battery Details: Cycle Time: 157 Bar Code:1ZEA684FVX9 FRU part: 42T4530 Can someone help me on what options do I have? I called up customer care and they said I am out of warranty since April, so they cant do anything. But I am sure going from 4 hours to 0 in 1 day is not natural death of the battery.
As well as this

the sudden death of battery could be due to the safety circuitry kicking in.

Not necessarily age-related. A couple of blown cells would most likely trigger the shutdown when discovered by the aforementioned circuitry.
