Hard Drive Cable

Mein Problem

MacBook Pro 2012 question mark on startup. Initially I thought it was the hard drive but I was able to boot the MacBook Pro from an external enclosure.

Meine Reparatur

It went very well until I had to attach the sensor bracket cable back into the ZIF connector. It was very difficult as it is very small.

Mein Rat

I would suggest not using the adhesive backing until it is attached. It is a lot easier to insert the ribbon cable back in when it is not attached to the bracket. Make sure it is a tight fit.
