DRIVER_POWER_STATE_FAILURE (0x0000009F)

What is DRIVER-POWER-STATE-FAILURE?

Stop code 0x0000009F indicates a driver failed to handle a power management state change properly. This BSOD is triggered when Windows transitions power states (sleep, hibernate, resume) and a driver does not respond correctly to the IRP_MN_SET_POWER request. Very common on laptops after Windows updates change USB, network, or GPU driver power management behavior.

Common Causes

• USB driver not completing power transition
• Network adapter failing to enter/exit sleep
• GPU driver power management conflict

Step-by-Step Fix Guide

• 1
  Update all device drivers, especially USB and network

  powercfg /energy generates a detailed power analysis report identifying drivers that fail power management requests.

• 2
  Disable fast startup in Windows power settings

  Disabling Fast Startup forces a complete shutdown cycle that resets power state tracking and avoids many resume-related BSODs.

• 3
  Check Device Manager for power management conflicts
