Check 2 If any other devices except to the AC adapter are not connected to the USB Type-C
adapter, go to Check 3. If any devices are connected, remove all the devices except
to the AC adapter and check the DC IN/Battery indicator again. If the indicator
lights, there is no problem. If not, go to Check 3.

trouble. If the indicator still does not light, the battery pack may have any trouble.
