MacBook – A1502 Late 2013 MacBook Pro will not boot, one exception

batterybootmacbook propower

The ONLY time it's booted since it's been in my possession was when it was in the Apple Store, when it ran the Apple Diagnostics.

What I've tried is:

  • resetting the SMC (no reaction)
  • using power on pads, which makes the MagSafe turn green for 2 seconds, and back to amber.
  • unplugging the battery and plugging it back in
  • plugging the MagSafe while battery is unplugged
  • unplugging keyboard from macbook and power on pads

Regardless of what I try, when I plug it in, it does the same thing. Fans won't spin up, and when I leave the MagSafe plugged in for about 10 minutes, it's noticeable that heat is coming from the part where the MagSafe usually is.

I don't want to throw it out and get a new one, I really want to get this one working, since new MacBooks are too expensive.

Any suggestions?

Good news, after a couple of months I FINALLY figured out the problem. After watching a Louis Rossmann video, I saw something about jtag connectors. I removed the jtag connector and the fans now spin. Along with that, it says the battery is low on the screen.

I'm assuming something at apple was able to turn it on. But now without the jtag connector it actually is working.
