I have a Lenovo T60 laptop which had a fine working battery a few months ago, but was unplugged since then. Now it won't hold a charge at all. When I check the winXP power manager it says:

The battery was completely discharged and needs to be charged. this may take up to 10 or more hours.

irrepable damage to the battery has been detected. replace the battery with a new one.

your battery can store 54% of its original full charge capacity.
How can a battery go completely useless? Even having it plugged in for 2 hours wont give it one second worth of charge, so I think there's a digital switch preventing it from charging. Is there any way for me to get it to charge? Just if it could hold a few seconds worth of charge would be all I really need.

(its a sanyo battery for t60 42T4504)

It's a possibility the battery is no good or something else. There is no way for you to tell what's going on, unless you're willing to get
a new battery and see if that works. If you do get a new battery, then get it directly from Lenovo.
Also lithium ion battery will always needs to be fully charge, but can't over charge it, and never drain down to 0%. If it's been left out for too long, then it loose ability to hold a charge. This is why it's pointless to buy a spare battery and keep it in storage. When the current one dies, the spare one will probably be dead as well.

Thanks for your reply. I'm unconvinced that a battery can go from "able to hold 2 hours of charge" to "unable to hold a single second of charge" after only 3 months of being left in a powered off laptop. There's gotta be some software process that refuses to provide charge to the battery due to the results of a diagnostic test that is below what it wants to see. I want to find a way to make that software process think the battery is good so that it would provide charge anyway. What process is the culprit and how can it be bypassed?
