Re: IBM Thinkpad t42 battery problems
As frost said. If it's a T4X series, that's now pretty old. And that's how lithium batteries can behave when there at the end of their life.
Time to replace it my friend.
I'd try ebay, you can get reasonably priced compatible ones, but checked the sellers feedback, because you can get some good and some bad imports. I've had to buy compatibles for dells and a X40 IBM. The dell compatible was superb, lasted longer than the orginal, the X40 was about the same, but never calibrated properly (it would take minutes dropping from 100% to 60% but then 2 hours draining to empty).
Just look about, probably get a decent replacement for about £35.
Hope thats of some help.
