Test the AC adapter using the UEFI Hardware Diagnostic tests

If the computer starts and you would like to test the AC adapter, use the following steps:

1. Make sure the power cord and adapter is connected to the system and wall outlet.

2. Press and hold the power button until the computer turns off completely.

3. Turn on the computer.

4. Immediately press the F2 key repeatedly, about once every second, until the UEFI Hardware Diagnostics screen is displayed.

5. In the UEFI Main menu, select Component Tests.
