crwdns2890332:0MacBook Pro logic board fuse?crwdne2890332:0I have the same issue and I have already replaced the upper case exactly following the steps on MacBook Pro 13" Unibody Early 2011 Upper Case Replacement . But the issue remains. The LSI dots are all white. I think the logic board is in good shape. Since I have already replaced the upper case with keyboard, I don't know what is the problem now. When I press the power button. The front white light was turned on, but the screen keeps off and the fan spins faster and faster. The fan noise will not stop, until I manually power the machine off. Can I examine the logic board myself? How to reset the logic board? BTW, I found @Mayer's comment about jump start. Could you please provide a picture of the power pads to be shorted please? Thanks a lot!
