![]() ![]() Oh, and apparently this seems to be a problem frequently experienced by owners of 2012 13-inch Macbook Pros (my model exactly). It is in Italian, but what the tech does is pretty clearly demonstrated, and someone in the comments section explains it in detail.īasically, you insert something non-conductive underneath the bottom RAM slot, and that stabilizes the RAM so that the laptop stops this lines, freeze, shut-down, 3 beeps thing.ĭo yourself a favor and watch this video!

At first, the 3 beeps would sound if I moved my laptop to another room, but soon, I only had to look at it wrong and then I’d get lines across the screen, everything would freeze, then my laptop would shut down.
