Hello, Tjsem!
Thanks for reaching out to Microsoft Community and posting your concerns with your Surface Pens that stopped working on your Surface Book. We are sorry to learn about this and we appreciate you letting us know so we can help you out.
You mentioned that you performed some troubleshooting steps and the issue is still present. Since the pen cap functions and inking is the only issue on your pens, may we know if you are able to zoom in and out using your fingers on to your screen? We need to know if it has something to do with the multi-touch feature preventing your pen to write.
In the meantime, check the steps below. You may have performed these steps, kindly complete them in the same exact order.
- Verify that the pen's LED light is coming on by pressing and holding the pen cap for 3-7 seconds.
Once on, please do the next step.
- Run Surface Diagnostic Toolkit and make sure to complete the tasks.
If your pen still does not ink, please reinstall the drivers of the pen and touch.
- While the Surface Pen is paired on your Surface device, open Device Manager.
- Click View on top and check Show hiddendevices**
- Expand Human Interface Devices> HID-compliant pen > Uninstall device
Surface pen settings > Uninstall device
Surface pen****integration > Uninstall****device
HID-Compliant touch screen > Uninstall device(if you see 2 of these drivers, uninstall both)
Intel (R) Precise Touch Device> Uninstall****device
- Expand Firmware> Surface****touch> Uninstall****device
- Expand System****devices> Surfacepenpairing> Uninstall****device
SurfaceTouchServicing****ML > Uninstall****device
Note: If prompted with a checkbox stating "Delete the driver software for this device", leave it unchecked then hit Uninstall. Do this for all drivers asked to uninstall
- Restart
- After Restart, check in Setting****s> Devices, if the Surface Pen is still paired on the device. If it is still paired, remove and add the Surface Pen again.
- Test the Surface Pen
We hope this helps you out. Otherwise, don't hesitate to update us so we can further assist you.
