Hi, Rhivinde!
Thanks for reaching Microsoft Community. We understand you have issues with the clipboard as it will not receive a charge. As you know, the batteries in the Surface Book may charge at different rates, depending on the power state of each battery. Whichever battery has less than 20% charge will be charged first. When both batteries are at 20%, the clipboard will charge to 85%, and then both batteries will charge to 100%.
May we know if you are using the charger that came in with the device?
Since the battery never charges above 50%, please check for the Battery Limit settings.
- Boot to UEFI and select Boot Configuration.
- Check if Battery Limit is enabled.
- Disable Battery Limit.
Please also force a shutdown and restart your Surface.
- Press and hold the power button until the screen turns off (about 10 seconds), then release the power button.
- Press and release the power button to turn your device back on. You should see the Surface logo.
If that doesn't work, use this two-button shutdown process to make sure your Surface turns off completely:
- Press and hold the power button on your Surface until the screen turns off (about 30 seconds), then release it.
- Press and hold the volume-up button and the power button at the same time until the screen turns off (about 15 seconds), 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.
Once they have been completed, please shutdown the device. Allow it to charge for about 45 minutes before turning back on.
We hope this helped.
Sincerely,
Janette_Z
