I’m in possession of a Lenovo ThinkPad T-410 that I got from my old job of about 4 years ago. It USED to power on and work just fine. Now?…even with the power adapter plugged into it, it just does nothing. No power, no lights whatsoever. What could be the problem? I already tried the “Remove-Battery-And-Hold-Down-Power-Button” routine with negative results. Is there someplace I can ship it to have it looked at? I mean its not a critical issue, but its got sentimental value to me, and I wouldn’t mind giving it a second life as a backup.
