Welcome to the Microsoft Q&A Forum!
I’m really sorry you’re dealing with a pen that’s connected but not writing, that can be frustrating, especially when you need it to work right away. Here are some focused troubleshooting steps to help you move forward:
1. Test Touchscreen Functionality
Try using your finger on the touchscreen. If touch isn’t responding, the issue is likely with the screen or digitizer rather than the pen itself.
2. Try a Different Pen Tip (Nib)
A worn or loose nib can cause the pen to be detected but unable to write. Replacing the tip often resolves this quickly.
3. Run Windows Update
Check Settings → Windows Update and install any pending updates, as these may include touchscreen or pen driver fixes.
4. Reinstall Pen & Touch Drivers via Device Manager
Open Device Manager → Human Interface Devices, uninstall HID‑compliant pen and any Surface Digitizer entries, then restart the device to reinstall fresh drivers.
5. Run the Surface Diagnostic Toolkit (SDT)
This Microsoft tool automatically checks hardware, firmware, and driver issues and can fix many pen/touch problems.
Download Surface Diagnostic Toolkit here.
6. Reset the Bluetooth Module
Turn Bluetooth off → wait 10 seconds → on, then re-pair your Surface Pen to refresh the connection.
7. Perform a Two‑Button Shutdown
Hold Power + Volume Up for 15 seconds, release, wait 10 seconds, and restart. This resets deeper Surface firmware components.
8. Test the Pen on Another Surface Device
If it writes on another Surface, your laptop’s touchscreen or digitizer may need service. If it doesn’t work elsewhere, the pen hardware is likely at fault.
Hope this helps. Let me know if there's anything else I can help you with!
