FAQ
• What happens if my system is not plugged AC in while WU start updating BIOS?
Before update starts, if AC is not plugged in and remaining battery is below 50%, a message will
be displayed up to 30 seconds. If an AC source is still not plugged in, update will fail. On
following boot, system firmware device in device manager will be yellow-banged.
