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! I followed the instructions yesterday and my laptop is back to its old, reliable self. I was just considering the necessity of purchasing a new laptop that I currently cannot afford AT ALL, when I came across this video: When I would press the power button, it would beep 3 times (repeatedly) but never. This is REALLY a pain because a laptop is supposed to be portable. Why is MacBook Pro beeping and not turning on Shut down the computer. If I tried to restart it, yes, that’s right: 3 BEEPS! 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. Or when the filter of the robot gets clogged, you hear three. I tried physically reseating my RAM and that worked for a while, but the problems reappeared and the frequency increased. If you do not hear both beeps, the schedule will not be set.
