Okay so my macbook has been malfunctioning for pass couple of months. I initially took it to the apple genius since I needed an immediate fix (I am a student and needed the laptop to get work done). They charged me $70 bucks to replace the SATA. The problem with this is that it constantly fails. I had to go in five different time to have them fix it. The last session lasted three months before in fail again so I decided to open it up and have a look. All I did was just pulled the SATA cable out and then power on the laptop to see if it works. I repeated this process three times before it worked again. This failure seems to be random and is not caused by a faulty SSD or cable. Has anyone experience this and figure out a permanent fix? I hate having the uncertainty of my device not working when I need it and having to go through the hassle of taking it apart then reassembling it to have it either work or not work.
