    Hi everyone. I have a MacBook (a1342) that recently stopped powering on. I know the power cable was fine and since the MagSafe led wasn't working, I decided to replace the magsafe board. I just finished the installation and plugged in the cord. To my delight, the led powered on right away! Unfortunately, the computer wouldn't power on. I had resigned myself to next having to replace the logic board. I left the battery charging while I was looking around at forums. I read a post where someone had mentioned that if the keyboard ribbon is not inserted exactly right, the computer would not power on. I unplugged the MacBook and messed with the keyboard ribbon and it powered on immediately. I then plugged in the power cable but now the MagSafe led is not powering on! I am using the 80w charger from my pro but I'd always thought that wasn't a problem.

    Does anyone have any idea what might be going on?

    Thanks

    Hi,

    The reason you need to fix the keyboard cable is that the power button is connected via the keyboard, which is quite irritating in my opinion.

    Anyway, for troubleshooting, disconnect the keyboard ribbon cable and use the jumper to power up the laptop. The jumper is two small solder points right above the keyboard port. I use the back end of a screw drive bit.

    If that works, then the issue is most likely not the Logic Board or the MagSafe board. However, that still leaves you stranded.

    Hope this helps.

    Regards
    Raptor
