Ruth,
My contact gave me the following for you to try (this is only for non US typecovers for SP4). Please let me know if you try these and results either way:
Workaround #1
- Power+volume up to boot into UEFI settings.
- Choose Devices.
- Toggle Type Cover Port off and then on.
Workaround #2
- Check Settings > Ease of Access > Keyboard and ensure that Filter Keys is disabled.
- Check BIOS and make sure Type Cover is enabled in Devices.
- In Device Manager, click on the View menu > Show Hidden.
- Under HID (Human Interface Devices), scroll down and find Surface Pro 4 Typecover Integration > right-click - Uninstall. (chose option to delete driver/software.)
- In Device Manager, under Keyboard, if you do not see the type cover, no need to do anything else. I; if you do see it, right-click, uninstall (check to remove software).
- Shut down (hold shift for a clean shutdown).
- Hold power and volume up for 30 seconds. The device will flash to EFI and back until it eventually powers off fully.
- Power on the device. Now the keyboard should work, and all the drivers should be re-installed that we removed earlier.
