17 Inch MacBook Pro Not booting up
My MacBook Pro 17 inch will not boot up. I replaced the battery and the charger, still no results. The only time it will boot up temporarily, is when I unseat and reseat the battery cable to the motherboard. The laptop will boot up on its own then there is a light blue screen and a bar on the screen showing the laptop booting up. Then the wallpaper shows up like normal, but will then shut down again and cannot restart the laptop. Please advise.
