standby/sleep issues. can anyone help?

by k20z3kid / January 15, 2009 10:02 AM PST

If I put my computer to sleep either through the start menu or if I do it by closing the lid the computer stays asleep until I plug the AC adapter in. Once I plug the AC adaptor in the computer wakes up. This is getting quite annoying because sometimes I just want to plug the laptop in without waking it up so that it can charge. But now I have to make sure the AC adapter is plugged in before putting it asleep in order for it to stay asleep. Can anyone guide me as to how to fix this? From my recollection the laptop did not do this before. I tried rescue and recovery back to an early point and its doing the same thing. Next step is a full factory restore. I hope someone can tell me how I can fix this so I do not have to do a full restore.

The laptop is a thinkpad SL400 with windows vista.

Check power options in control panel and look at you sleep mode options and make sure sleep mode is set correctly other wise there may be OS issues. i had the same issue and i reinstalled vista and it fixed issue

Cheat? (3 ideas here.)

1. Not a fix. Set the machine to sleep in 5 minutes.

2. -> Did ANYONE run a registry cleaner? I encountered your issue and it occurred every time we reloaded the OS and they ran the cleaner. We never could figure out anything but to say "don't do that."

3. INVESTIGATE with the MCE power state tool noted at
(MCE standby tool)

Good luck, happy hunting.
