Hi @Rauf-,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

The DRIVER_POWER_STATE_FAILURE (0x9F) stop code means Windows detected a driver that failed to transition between power states correctly, often during sleep, wake, or boot. Since it happens on both Windows 10 and 11, this points to a driver or firmware issue, not the OS itself.

Why It Happens

• Outdated or incompatible graphics/chipset drivers.
• Corrupted power management settings.
• BIOS/UEFI bugs after updates.
• Faulty hardware (less common, but possible).

Recommended Fix Steps

1. Boot into Safe Mode

• Interrupt boot 3 times → Advanced Options → Startup Settings → Safe Mode.
• If it runs in Safe Mode, the issue is driver-related.

2. Update or Roll Back Drivers

• In Safe Mode: 
  • Open Device Manager.
  • Update graphics (Intel/AMD/NVIDIA) and chipset drivers from HP Drivers & Software.
  • If the problem started after a driver update, roll back the driver.

3. Update BIOS

• Go to HP Gaming Pavilion - 17-cd0355ng | HP® Support.
• Download the latest BIOS and install it.
• If the issue started after a BIOS update, check if HP offers a rollback option.

4. Disable Fast Startup

• Control Panel → Power Options → Choose what power buttons do → Uncheck Turn on fast startup.

5. Run HP Hardware Diagnostics

• Restart → Press Esc → F2 → Run System Tests.
• If RAM or SSD fails, note the error code.

6. Check Power Settings

• In Device Manager → Network adapters, disable Allow the computer to turn off this device to save power.
• Do the same for storage controllers.
