|... take a good look @ the socket where the ac/dc adapter plugs into the laptop I remember fixing one when the middle section "pin" split (like a reed) and peeled back touching the outer connection.|
... one section of the split bent backwards and was shorting the connection turning it off.
... I managed to just bend it back into shape, be carefull not to snap it!
... there is logic to this madness!
the element of surprise Grrrrrrrr
