  • The first thing to try in another known good power supply.

    Will the laptop heat up plugged in, just sitting or are you using it, gaming?

    Are the air exaust ports on the bottom clean and clear? Air intake not bocked?

    Another thing that can happen is the fan gets clogged between the fan and the heatsink and you can't tell by looking in the intake.

    Worst case is you have a problem with the voltage regulator on the motherboard.

    BUT WEHEN MY LAPTOP IS OFF AND I PLUG IN MY CHARGER ..THE ETHERNET PORT LIGHT COMES ON ...IS THAT NORMAL

  • Charging the battery has a byproduct of heat. How hot is it getting and is is just sitting,OFF, charging or are you using it and are you playing games while you are using it?

    Has the ETHERNET PORT LIGHT always come on when you are charging?
