Hi,
If your Surface won’t wake up from sleep, try to simultaneously press the Windows logo key +Ctrl+Shift+B.
Here are some solutions that you can try to help resolve the issue.
Force shutdown your device
Press and hold down the power button until your Surface restarts and you see the Windows logo screen (this takes about 20 seconds), then release the power button.
Install the latest Surface and Windows updates
We recommend that you install the latest updates to keep your Surface performing its best. You can get updates now by checking Settings > Update & Security > Windows Update. You can find the details of the latest update on our Surface Book 2 update history page.
Clean the connectors on your Surface Book
- 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.
If none of the solutions work, I suggest that you bring your device to a Microsoft Store near you and have it checked by one of our personnel. You may also contact our Microsoft Support team for further assistance. If you're outside the US, contact our Global Customer Service.
