"Broken power button, jump start?"に関する回答I would say if your warranty has expired, you have nothing to lose, i.e. you cannot damage a damaged LogicBoard, or if you mess it up (or not) Apple will offer you a replacement of the LB anyways. This jump start saved me about 400USD, what was the offer of Apple as they said, "we have to replace the LB is necessary, no other way" !?!?! Try it, maybe with an friend who has more knowledge of electronics And just jump start it. My old MBP now works perfectly, my wife uses it, just said her not to turn it off
"Broken power button, jump start?"に関する回答Had the same issue with my 2010 MBP. All but Power button is working. I have jump started the machine, thanks to this link You just have to touch the two pins with a flat screw driver. Try this by touching the pins with the screw driver a few times. This saved my old MBP Broken power button, jump start?
