Inspect the port and adapter
Examine the charging port on your laptop for any visible obstruction or damage. Also, inspect the power adapter for loose connections.
Clean the port
Use a dry cloth to carefully clean the charging port. Do not use liquids or powders to clean the port.
Use a different power adapter
Try connecting your laptop with a different power adapter – if it works, then you must replace the old one.
Have a technician replace the charging port
In case the above steps do not fix the issue, you must take your laptop to a technician for further inspections and repairs.
