i know there've been like a million posts like this, but
i have a a21m thinkpad, like 5 years old.
i shut my computer down when i left for vacation. apparently, it was really cold while i was gone (i don't know if that is significant or not). when i got back, the battery indicator light was actually green (it's usually orange, and recently it:s been flashing orange--i guess the battery:s pretty much dead), and when i pressed the on button, nothing happened except that the indicator light flashed once, still green, and this other light flashed (that shows the computer is thinking or something?). and that:s all that happens. help!
