Hey There, I am Sofia Carter. There are various causes for the HP Laptop Not Charging problem. The two-in-one AC adapter, which can be found in many PC chargers, connects to your computer with one end and the wall with the other. You can have a faulty or damaged cord if both are firmly connected yet your PC's charging light is still off. It's also possible that your computer is configured to enter sleep mode or to shut down quietly after a specific period of inactivity.
