Problem: Charger is plugged in and working normally (light shows up on charger tip when plugged into SB), but Windows says "plugged in, not charging" next to the battery icon.
Solution: Try the default troubleshooting first but if that fails (and uninstalling/reinstalling of battery device drivers doesn't help):
Force shut down your SB (hold down volume up and power button for ~15 seconds).
Even after the device turns off, keep holding down both buttons until it turns on again and then let go.
It should boot into bios, make no changes to the bios and exit, reboot back into Windows.
Hopefully Windows reports that your batteries are charging again.
完美解决~~
