Hi All, My 13” MacBook Pro late 2011 was just fine until one day it was off and would not turn on. The indicator on the charger was/is solid green, however, the charger has been tested and works on other systems. All 5 green lights flash on the battery indicator 5 times. I bought and installed a replacement battery but the symptoms did not change.I replaced the RAM with the original RAM (I installed 2x4gb the year I bought it) but the symptoms did not change.The logic board gets warm in the center when the charger is plugged in.No fans ever spin, white light on the front never comes on, and I never hear any sounds from the laptop whatsoever.There has never been water damage. I and a more experienced friend inspected the motherboard and found none. Does anyone know what the issue may be? Is it possible that the magsafe inboard connector is bad? Thank you all!
Brandon Hughey try a few of these things first:
you also want to remember that your logicboard has some “power-on pads”. Those will allow you to start your board bypassing the button etc. They were actually intended as debug power button. Going by your computers description, your logicboard should be a 820-2936-B Let us know if this is right and if you can post some pictures of your board with your question. It will make it easier to identify. Adding images to an existing question
