Two stopcodes are shown during the bluescreen error :

1. DRIVER POWER STATE FAILURE
2. APC INDEX MISMATCH

HOW TO FIX THESE ERRORS ?

Answer 1

Please check to see if your laptop is producing any minidump files, I will check those to see if they provide any insight into a potential cause of the system crashes.

Please do not upload a very large Memory.dmp file.

Open Windows File Explorer.

Navigate to C:\Windows\Minidump

Copy any minidump files onto your Desktop, then zip those up.

Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

Then post the link here to the zip file, so I can take a look for you.

Answer 2

To troubleshoot the blue screen errors you are experiencing on your Dell Latitude E7450 running Windows 11, you can follow these steps for each stop code:

1. DRIVER POWER STATE FAILURE (Stop Code: 0x0000009F)

This error indicates that a driver is in an inconsistent or invalid power state. Here are some steps you can take to fix this issue:

• Remove or Update Drivers: If you have recently added new device drivers or system services, try removing or updating them. Determine what changes occurred in the system that might have caused this error.
• Check Device Manager: Open Device Manager and look for any devices marked with an exclamation point (!). Review the event log in the driver properties for any faulting driver and try updating it.
• Event Viewer: Check the system log in Event Viewer for additional error messages that might help identify the device or driver causing the issue. Look for critical errors that occurred around the same time as the blue screen.
• Power Options: Temporarily disable power saving features in the Power Options settings, as some driver issues are related to system hibernation and power states.

2. APC INDEX MISMATCH (Stop Code: 0x0000001A)

This error typically indicates a problem with the system's memory or a driver issue. Here are some troubleshooting steps:

• Check for Faulty Drivers: Similar to the previous error, check for any recently installed drivers that may be causing the issue. Update or uninstall them as necessary.
• Run Memory Diagnostics: Use the Windows Memory Diagnostics tool to test your computer's memory. You can find this tool in the Control Panel by searching for "Memory" and selecting "Diagnose your computer's memory problems."
• Check for Hardware Issues: If you have recently added new hardware, consider removing it to see if the issue persists. Ensure that all hardware is compatible with your version of Windows.
• Event Viewer: Again, check the Event Viewer for any additional error messages that may provide more context about the APC INDEX MISMATCH error.

By following these steps, you should be able to identify and resolve the issues causing the blue screen errors on your laptop.
