My thinkpad t21 just died! It started 2 weeks ago when I would turn it on, sometimes the screen would not light up or come on. I could see in the shadow, if there was a light on the screen that it was booting up, because I could vaguely see the thinkpad logo, and then eventually my icons, but this was all while the screen was still dark!!! When or if it did come on it took about 20 minutes or even longer, before the screen would light up and I could see anything! Now, nothing! When I push the button for it to start up, the keys do not even light up, just nothing. The only light I see is from the battery light, because it is plugged in. What should I do? Do I need a new battery or is this computer now dead in the water?
