STOP: 0x0000009F


A device driver is in an invalid or inconsistent power state from either shutdown or going into or returning from hibernate or standby modes.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

  Sample Screen  

A problem has been detected and Windows has been shut down to prevent damage to your computer.


If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

The driver is in an inconsistent or invalid power state.

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 specifies the cause of the issue.

0x00000001 The device object that is being freed still has an outstanding power request that it has not completed (Windows 2000 and later).
0x00000002 The device object completed the I/O request packet (IRP) for the system power state request, but it failed to call PoStartNextPowerIrp (Windows 2000 and later).
0x00000003 A device object has been blocking an IRP for too long a time. (XP and later).
The device driver did not properly set the IRP as "pending" or complete the IRP (Windows 2000 only).
0x00000100 The device objects in the devnode inconsistently used DO_POWER_PAGABLE (Windows 2000 only).
0x00000101 A parent device object has detected that a child device has not set the DO_POWER_PAGABLE bit (Windows 2000 only).
0x00000500 The device object completed the IRP for the system power state request, but it failed to call PoStartNextPowerIrp (XP and Server 2003 only).

Parameter 2 depends on the value of Parameter 1.

Parameter 3 depends on the value of Parameter 1.

Parameter 4 depends on the value of Parameter 1.
