Here's something I found which may (or not) be of help "the secret power button code to revive your dead Thinkpad. After assessing the situation (totally dead laptop) he warned me: “Okay, this is going to sound totally bizarre, but I want you to give this a try…” He then had me unplug the AC adapter and take out the battery. Then, you push the power button 10 times in a row at one second intervals. Next, you push and hold the power button for 30 seconds. Then you put the battery back in and push the power button… and she lives. The computer came back, good as ever."
