Verify that the power adapter is firmly plugged into the outlet, and that the power supply is firmly connected to your computer.

Check that your computer is set to charge the battery, and that it is not set to run solely on battery power.

If the connections seem secure, ensure that the charging port is free of dust, debris, or any other obstruction.

Try using a different power adapter as the one you’re currently using may not be working correctly.

Check that your battery is in good condition by verifying the level of charge. If the battery is too low, it cannot charge.
