Hello! As the title says, my MacBook Pro is unable to read the RAM, and this is the third time it has happened. Each time I got the error (three beeps/sleep light blinking thrice), I had moved my Mac from one place to another (moving rooms, etc). I got the RAM upgraded after the first time and got it fixed again (took it put and put it back in) after the second. I am currently having the problem again. Before this happened, I moved my laptop to another table. It kept restarting, so I turned off. When I tried to turn it back on, it started beeping again. I have yet to open it up. Is there anything I can do to stop this from happening again?
Well it s 90% likely a RAM issue. Please tell us the type of RAM you install and how much. See if you can go under the Apple in the left hand corner to about this Mac, click on the Memory and tell us what it reporting. Open the machine up and remove the RAM and then reseat it. Moving from one table to another really doesn’t help. If after reseating, it it continues, we want to test the slots and the RAM. So remove one stick and restart and see if it persists. Now move it to the other slot and test. Do this with the other stick and let us know your findings. MacBook Pro 13" Unibody Mid 2012 RAM Replacement
