Understanding the Green Light on the Power Supply
The green light on the power supply of your HP laptop indicates that it is receiving power and is functioning correctly. When the light turns off unexpectedly, it suggests that there might be an issue with the power supply or the connection between the power supply and the laptop.
Possible Causes of the Green Light Turning Off
