We had a call from a customer with 3 surface pros that were no longer charging. We discovered it was a known problem. The fix is to go into the “Device Manager” and uninstall the battery. Make sure to not remove the AC device. Restart and the correct driver will re-install. There is one more step to run a fix. This will keep this issue from coming back. We found the fix on this page.
