I just tried the below from https://windowsreport.com/detach-surface-book-from-keyboard/ and it then started charging battery 1. To perform a two-button shutdown on your Surface Book, do the following: Turn your Surface Book off. After your Surface turns off, press and hold the volume-up button and the power button at the same time for at least 15 seconds, then release both (The screen might flash the Surface logo, but don’t release the buttons for at least 15 seconds). After you release the buttons, wait for 10 seconds, and then press the power button again to turn on your device. One you performed a two-button shutdown, try to detach your Surface Book from the keyboard, and it should work without any problems. In case you’re still unable to detach it, try some of the following solutions.
