Hibernate and Sleep result in machine limbo / crash

I have a:



T400 2765-PCU
ATI Radeon HD3470
Windows 7 Pro

Hibernate and Sleep used to work. Then I recently updated things via System Update and Windows Update. Now if I try either, they both result in a blank screen and machine limbo. The screen powers off but the hard drive, power lights, and fan stays on. If I just let it sit the machine will eventually reboot after about 7 minutes. Otherwise I can force poweroff by holding down the power button.

Some of the things I have already tried:
  • Updated all drivers to current using System Update - no dice
  • Tested using both the integrated graphics and the ATI card: same result - Hibernate and Sleep both cause machine limbo.
  • Rolled back power management driver to dated 11/18/2009 no dice
  • Rolled back ATI Radeon Driver to 8.641.1.1000 dated 8/24/2009 - no dice
  • Uninstalled all the ATI Catalyst software - no dice

I understand this is a fairly common problem with Thinkpads. Any help would be appreciated!

Re: Hibernate and Sleep result in machine limbo / crash

hey cooljw,

could you use msconfig and disable all startup items. then try to hibernate/sleep the unit.

there might be a program that is running in the background that is causing this. at the same time, do go to and crosscheck with your system and update any drivers/software that might be outdated.

Hi, the same was/is happening in my T400. I found out, that the cause was Skype. When I close Skype before putting the mashine to sleep - it works
