T400 System board issues

2009-05-05, 15:06 PM
Has anyone else been having issue with the T400 and the System Board.  I have had 5 now that stop booting.  All you get is the power light, battery light and the plug light when plugged in.  Hit the power and nothing comes up.  I tried removing the battery and same thing minus the battery light.

I've been having the exact same problem with my T500. I replaced the original system board, and it worked for about 45 minutes, then started exhibiting these symptoms, again.

I am also facing the same problem. Looks like Lenovo is loosing it credibility and integrity, it previous used to have, especially for Thinkpads.


I am already living with WiFi problem for my T400. Now this System board issue. Really tech support also not good at all.

I have found that if you remove the palm rest, unplug the Bios battery for about 5 minutes, plug everything back in, it will fire right up. Its not a permanent fix though, but it at least gets it going again.
