Chosen Solution Please HELP! Fan Doesn’t stop and Loud, Power Button doesn’t work, battery indicator doesn’t and the battery is not recognized even though it’s working fine and I’m using it, all of these coming from the same problem source which is definitly from the broad, Anyone knows what is it? So I bought this macbook pro mid-2012 A1278, and I tried a different board to check that all other components are working good, battery is perfect, DC power port is good, battery indicator is good also, so I open the macbook by either removing the battery and connecting the power cable and starts automatically or just unplug the battery and connect it again which prompt the macbook to start also automatically and runs fine on the battery but the OS doesn’t recognize it and it says 0% charged even though it’s not true, also when I connect the power cable it doesn’t light up even though when it works!...
