Hi Grace BX,
Thank you for posting in Microsoft Community.
I understand that you’re experiencing issues with your Surface Pen not writing on your Surface Pro 7 after a Windows 10 update. I am here to help and let us work on this together.
Allow me to ask some questions so we can further isolate your issue and formulate appropriate troubleshooting steps.
For the meantime, kindly try the following steps below:
- Force the device to shut down and restart. Press and hold down the power button until your Surface shuts down and restarts and you see the Windows logo screen (about 20 seconds), then release the power button.
- Run Surface Diagnostic Toolkit and check any pending updates available including optional updates. See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com)
- Uninstall reinstall the touch driver.
- In the search box on the taskbar, enter device manager, and then select Device Managerin the list of results.
- Expand the Human Interface Devicescategory.
- Right-click Intel(R) Precise Touch Device, select Uninstall device, and then, in the Uninstall Devicedialog box, select Uninstall.
- Right-click HID-compliant touch screen, select Uninstall device, and then, in the Uninstall Devicedialog box, select Uninstall. If you see two HID-compliant touchscreen drivers, right-click the first, select Uninstall device, select Uninstall, and then repeat the process for the second driver.
- From the Actionmenu, select Scan for hardware changes.****You may also need to restart your Surface. It will automatically download and install the touchscreen driver when connected to the internet.
- Remove and reseat the pen tip (either by fingertip or extraction tool). Test on known app.
- Reseat the AAAA battery in the pen, and test on known app (Change the battery in Surface Pen). Open pen and remove and reinstall the same battery to ensure good connection.
I hope the provided solution works for you. I look forward to hearing from you.
Kind regards,
Lavenia
