I have a 2010 macbook pro that recently just started turning off on me. I can sometimes get it turn on and when it does about 15 seconds into boot it powers off. I tried the smc reset and it seemed like it worked. But my fans would be at max and it didnt seem to register a charge. Im not sure what could be wrong with, ive barely used it. My battery is fine last time i checked it was at 88-90% life wise.
