BSOD after sleep

The issue you're experiencing with the BSOD (Blue Screen of Death) after sleep, specifically the DRIVER_POWER_STATE_FAILURE with the bug check code 0x0000009f, indicates that a driver is in an inconsistent or invalid power state. Here are some troubleshooting steps you can take:

1. Update Drivers: Since the problem is related to the driver, check for updates for your device drivers, especially those related to power management and the graphics driver. You can do this through Device Manager.
2. Remove Recent Changes: If you recently added new device drivers or system services, consider removing or updating them. Identify any recent changes that might have triggered the issue.
3. Check Device Manager: Open Device Manager and look for any devices marked with an exclamation point (!). Review the event log displayed in the driver properties for any faulting drivers and update them as necessary.
4. Event Viewer: Check the system log in Event Viewer for additional error messages that might help pinpoint the device or driver causing the error. Look for critical errors that occurred around the same time as the BSOD.
5. Power Options: Temporarily disable power-saving features in the Power Options settings to see if that resolves the issue. Sometimes, driver issues can be related to the various states of system hibernation and power suspension.
6. Run Hardware Diagnostics: Since it's a work laptop, running any hardware diagnostics provided by the manufacturer can help identify if there are underlying hardware issues contributing to the problem.

If these steps do not resolve the issue, you may need to consider reinstalling the operating system as a last resort, but ensure to back up your data and software configurations first.

Thanks AI – have recently had a Windows update (since the issues began), all looks up to date. Couldn’t find specific power and graphics components to update in Device Manager, and no exclamation marks there either. I’d already removed all new components that I considered possible culprits. Power options – had tried all possible combinations already.

Event Viewer gave me great new details – every time there is an BSOD post sleep, a critical error is logged. The details are always the same:
