I have a ThinkPad T400 with Windows Vista Ultimate.

When I try to go to Standby, I often get a DRIVER_POWER_STATE_FAILURE stop code.

At first, WinDbg flagged it as the Citrix Deterministic Network enhancer. After downloading the latest version from Citrix, WinDbg flags the latest memory dump as VMNetSrv.sys.

However, I already have the latest service pack of Virtual PC 2007.

Does anyone have any suggestions?

Ideas for resolving sleep problems:

  1. Look in your BIOS for the suspend ACPI options and try to switch modes among "S1 and S3", "S3" etc.
  2. Turn off Hybrid sleep, see explanation here (for vista, but is the same)
  3. The hibernation file is sometimes disabled by disk cleaning, to restore do in cmd run as administrator "powercfg -h on".

Note: Any of the above manipulation that doesn't help should be undone.

In Windows 7 you can use the following command to troubleshoot sleep problems and return a detailed report:

powercfg -ENERGY

Unfortunately, I've tried all of those measures and I'm using Windows Vista. Perhaps this would be a good reason to use W7... – Zian Choy Feb 2 '10 at 16:14
