Hi,
This can be software or hardware driven issue. Here are some solutions you can try:
Force shutdown your device
- Press and hold the power button on your Surface for 30 seconds and then release it.
- Press and hold the volume-up button and the power button at the same time for at least 15 seconds and then release both.
The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds. 3. After you release the buttons, wait 10 seconds. 4. Press and release the power button to turn your Surface back on. You should see the Surface logo.
Clean the connectors on your Surface Book
If you're using a Surface Book, try cleaning the connectors between the Clipboard and the keyboard.
- Detach the Clipboard from the keyboard.
- Clean the pins on the connector with a pencil eraser. Rub the eraser back and forth across the pins.
- Wet a cotton swab in rubbing alcohol. Clean the pins on the long, narrow part of the charger that you plug into your Surface. Rub the cotton swap back and forth across the pins. After you are done cleaning the connector pins, make sure that the pins are dry, and then reattach the Clipboard to the keyboard.
