2.20 USB Type-C adapter Troubleshooting
On some models, a USB Type-C adapter (USB-C to VGA/LAN adapter) is bundled.
To check if each function of the USB Type-C adapter work properly or not, follow the steps
below.
2.20.1 USB Type-C port (power delivery charging)
To check if the USB Type-C port is malfunctioning or not, follow the troubleshooting
procedures below as instructed.
Procedure 1: Connection Check
Procedure 2: Replacement Check
Procedure 1 Connection Check
Check if the USB Type-C port charges the power with an AC adapter (USB-PD type). How to
connect the AC adapter and the USB Type-C adapter is as follows;
1. Connect the power cord to the AC adapter (USB-PD type). Then connect it to the USB
Type-C connector (power delivery charging) on the USB Type-C adapter.
2. Plug the power cord into a live wall outlet.
3. Connect the USB Type-C adapter to the USB Type-C connector on the PC.
4. Make sure that the DC IN/battery LED glows.
If the DC IN/battery LED glows, power delivery function is working.
If the DC IN/battery LED does not glow, make sure that the power cord, USB Type-C adapter
and PC are connected firmly each other. If connection is loose, reconnect it firmly and return
to Procedure 1. If the problem still occurs, perform Procedure 2.
Procedure 2 Replacement Check
Check 1 The power cord or the AC adapter may be faulty. Replace them with new ones. If
the problem still occurs, perform Check 2.
Check 2 USB Type-C adapter may be faulty. Replace it with a new one. If the problem still
exists, check the PC condition.
