Hi AndreasWichmann,
Greetings! Thank you for posting in Microsoft Community.
I'm sorry to hear that the type cover and Surface pen aren't functioning anymore. Just to confirm few questions:
- Does the issue on the Pen happens to all writing apps?
- May I also confirm the exact model of your pen? see: Identify your Surface Pen and features.
- Do you see an LED on the Pen?
- Does the issue happens to all keys and touchpad?
Please perform the methods below:
- Run Surface Diagnostic Toolkit and make sure to complete the tasks.
- Check the settings for new or remaining Windows updates.
- Try to go to device manager, look for Surface Hot Plug - KIP > check if there's an exclamation point.
- Run the System File Checker.
- Test the keyboard in the UEFI environment. The UEFI environment is outside the Windows system so any issues that persists on the UEFI could be potential hardware issues. Go to settings > Update & Security > Under Advanced Start up , click on Restart Now, once you're on the UEFI settings, Go to Troubleshoot > Advanced options > Click on Command Prompt > Type "notepad" > test the keyboard.
The free upgrade to Windows 11 started last October 5, 2021 and will be phased and measured with a focus on quality. Following the tremendous learnings from Windows 10, we want to make sure we’re providing you with the best possible experience. That means new eligible devices will be offered the upgrade first. The upgrade will then roll out over time to in-market devices based on intelligence models that consider hardware eligibility, reliability metrics, age of device and other factors that impact the upgrade experience.
We expect all eligible devices to be offered the free upgrade to Windows 11 by mid-2022. If you have a Windows 10 PC that’s eligible for the upgrade, Windows Update will let you know when it’s available. You can also check to see if Windows 11 is ready for your device by going to Settings > Windows Update and select Check for updates.
