You can bypass the warning and in my case the AC adapter provided enough power to use the laptop and charge it at the same time. When you get an alert, choose to just bypass it instead of ignoring it in the future. Check if the power supply is working and you can actively charge your laptop. After verifying that the PSU is working, you can instruct the BIOS to ignore this warning in the future.
