SYMPTOMS

You may receive a "STOP 0x0000009F DRIVER_POWER_STATE_FAILURE" error message in Windows.

CAUSE

This behavior occurs when drivers do not handle power state transition requests properly. The error message most often occurs during one of the following actions:
  • Shutting down
  • Suspending or resuming from Standby mode
  • Suspending or resuming from Hibernate mode

RESOLUTION

To prevent the error message from occurring, update or remove the offending driver. This behavior is not limited to device drivers; it can also occur with file system filter drivers (for example, drivers installed by an anti-virus, Remote Control, or backup program). To isolate the driver that is causing the problem, use the following steps:
  1. Check to be sure your computer and all devices are on the Hardware Compatibility List (HCL) and have WHQL signed and certified drivers. You can use Sigverif.exe to check for unsigned drivers.
  2. Check for driver updates that may be available for your hardware.
  3. Update software that uses filter drivers (for example, anti-virus, remote control, and backup software).
  4. Uninstall any non-critical devices and software to help isolate the device/software that may be causing the problem.
  5. Install Windows in a new folder. Add drivers and restart as you proceed to isolate the driver that is causing the problem.
