Your Acer Nitro may use a two stage AC adapter that requires a secondary push to ensure it is fully inserted. You should hear a slight click when the adapter is properly connected and the charging indicator light will illuminate. Once connected, you should orient your adapter horizontally as shown in the image below.
Note: Your system may not power on if your AC adapter is not properly connected.
