When my HP G56 laptop was just a little over one year old I went to turn it on and it won't do anything. When I have the charger plugged in the light where it plugs in does not light up. I have tried several things and nothing has worked. Hopefully someone else has another idea or they can tell me if I need a new motherboard since that is what the guy at Best Buy Geek Squad thought after trying a few things. This is my elderly mother's computer and she rarely even uses it and mostly to play installed games. It is very frustrating that it barely worked a year.
This is what I have tried so far:
Using another power supply to make sure mine is not dead.
