Van toepassing: Windows 7 Service Pack 1Windows 7 UltimateWindows 7 Enterprise Meer

This article describes an issue that occurs when you restart the computer in x86-based version of Windows 7 Service Pack 1 (SP1). A hotfix is available to resolve this issue. The hotfix has a prerequisite.


When you try to restart the computer, the system may crash with a Stop error message that resembles the following:
STOP: 0x0000009F ( parameter1, parameter2, parameter3, parameter4 )

  • This Stop error indicates a DRIVER_POWER_STATE_FAILURE issue.
  • The parameters in this Stop error message vary, depending on the configuration of the computer.
  • Not all "0x0000009F" Stop errors are caused by this issue.


This issue occurs because the Trusted Platform Module (TPM) does not respond the power I/O request packets (IRPs) in time. Therefore, the system crashes.


To resolve this issue, we have released a hotfix for x86-based version of Windows 7.

Note This issue for x64-based versions of Windows 7 or Windows Server 2008 R2 is resolved in hotfix 2920188.
