Hi, GrahamHolden3!
Thanks for reaching out to Microsoft Community and posting your concern. We are sorry to learn about your Surface Pen that doesn't ink on your Surface Laptop 2. Thanks for pointing out that the pen cap works as it helps us isolate the issue.
First thing to test is LED light functionality. If the LED light doesn't turn on, this is a power issue. May we also know if multi-touch works on the screen? Can you zoom in and out with your fingers?
For the meantime, you may need to do the following:
· Check for Windows Update:
Go to Settings > Update & Security > Windows Update > Check for Updates
Please restart your device to apply the updates.
· Run Surface Diagnostic Toolkit and make sure to complete the tasks.
· Reinstall drivers.
Please do these steps in exact order to troubleshoot the issue:
- While the Surface Pen is paired on your Surface Book, open Device Manager.
- Click View on top and check Show hidden devices
- 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 > Surface pen pairing > Uninstall device
Surface Touch Servicing 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 Settings > 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
If this answers your question, please let our Community know by marking this post as an answer. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
