Oh Great LJ Brain Trust...

My IBM ThinkPad X31 hangs when I unplug it. It may or may not dim the screen for a few seconds first (dimming the screen is in my power saver settings). Then the screen goes blank, the disk (as far as I can tell by ear and by the indicator light) shuts down, and the computer does not respond to anything except holding down the power button long enough to just plain shut it off.

It works fine on battery as long as it was booted on battery. It won't transition.

This has been going on for only a few days. For the first two years I've had it, it has never exhibited this problem.

Is there a way to make it STOP doing this?

edit: Dangit, I was going to try swapping batteries and removing the new memory and all, but now it HAS stopped. I can't get it to do it at all. Which means I can't trust it. ObSheesh: Sheesh.

Both docked and undocked -- and now it QUIT so no more troubleshooting and no trusting it! Grf! (A battery swap would have been an *easy* thing to try, too. We've got several compatible ones in the house, between the two of us. Cool idea.)

I think I'm gonna go with quasigeostrophy's opinion that the mobo's bad. The kind of "it's dead, Jim" you're describing sounds like either a bad charger board (which is usually integrated) or a bad mobo itself.

You might see if this link will give you some guidance about POST error codes. If the ThinkPad is anything like the Empire's portables, there will be error codes that come up even when you can't power on the system properly.
