1. Plug in your HP charger and let it charge for 15–30 minutes. Check whether the small light next to the charging port turns on.
2. Then unplug the charger and anything else connected (dock, USB devices), and hold the power button down for a full 30 seconds. Plug the charger back in and press the power button once.
