It is most likely the Tantallon capacitor on the logic board. It will need to be replaced by someone who knows how to remove the old one and solder on a more capable one . All the 2009/2010 17”machines have this weak spot, and will eventually pack it in. But the fix is easy, if you know how to solder and read the schematics.
