Hi DefJam1974,
Thank you for reaching out to Microsoft Community.
Just to confirm, aside from this strange battery phenomenon, is your Surface Pen working like the inking and erasing function?
Please do these steps to troubleshoot the issue:
1: Run Surface Diagnostic Toolkit and check Windows Update
2: Update drivers and firmware
Check what is the current OS Build of your Windows version by going to Settings > System > About.
Go to Download driver and firmware for Surface, choose Surface Pro 7 then click Download on the next page.
Choose the .msi file that matches your current OS Build and click Next.
After downloading, run and install the .msi then Restart.
If issue still persist, please try this steps below:
- While the Surface Pen is paired on your Surface, 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 have 2 of these drivers, Uninstall both)
Intel (R) Precise Touch Device> Uninstall device
Note: If prompted with a checkbox stating "Delete the driver software for this device", leave it uncheck then hit Uninstall.
- Expand Firmware > Surface touch > Uninstall device
Note: If prompted with a checkbox stating "Delete the driver software for this device", leave it uncheck then hit Uninstall.
