Hey all,
Use of the Recovery process may not be necessary for this topic:
If your specific symptom is:
Keyboard and Touchpad stop functioning, and the "Surface Hot Plug - KIP" is yellow alert marked in Device Manager, below are the steps to resolve the issue. This is usually a result of a user accidentally ejecting the keyboard from the USB devices within the Task Bar menu. Note: though typing and touchpad do not function, backlights and Caps and Fn keys do still light up.
**Resolution:**
Need to disable and reenable the Surface Hot Plug - KIP in Device manager:
- Detach typecover from device, and open Device managers
- You may need to activate the on-screen keyboard- go to start>settings>accessibility>keyboard : toggle on "on-screen keyboard" for a working on-device keyboard.
- Within Device Manager, under system devices, open the yellow alert driver "Surface Hot Plug - KIP" > under "driver" tab, click "disable device" and then click "enable device" > click okay and device will need to restart.
After restart reattach typecover and it should now fully function.
If this is not your specific symptom, you should follow StevenK's guidance above, or contact the Surface support team.
Thanks,
