MacBook beeping 3 times

I tried physically reseating my RAM and that worked for a while, but the problems reappeared and the frequency increased. 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. If I tried to restart it, yes, that’s right: 3 BEEPS!

This is REALLY a pain because a laptop is supposed to be portable.

I was just considering the necessity of purchasing a new laptop that I currently cannot afford AT ALL, when I came across this video:

It is in Italian, but what the tech does is pretty clearly demonstrated, and someone in the comments section explains it in detail.

Basically, 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.

Do yourself a favor and watch this video! I followed the instructions yesterday and my laptop is back to its old, reliable self.

Oh, and apparently this seems to be a problem frequently experienced by owners of 2012 13-inch Macbook Pros (my model exactly).

I agree with Machead3. Here is iFixit's article on replacing MacBook Pro RAM:Article. This is for the early 2011 model, but it should be very similar for any non-retina MacBook Pro. If your Mac is not an early 2011 model, iFixit should have an article for any model.

For MacBook Pro 2015 A1502 model the RAM is soldered to the logic board. What is my option when this MacBook is beeping 3 times continuously and not turning on. Please help.

If you tried new RAM and/or reseating it you may need a new logic board. Alternatively maybe just one slot is damaged. You maybe able to get more life out of it by just keeping one stick of RAM in if it works.

Just another guide for you, I’ve just done this {28 JUNE 2019}

solutions for 3 Beeps

1. Upgraded your RAM

2. RAM undetected

If any of your RAM goes undetected, also the chime doesnt happen and the only sound is of 3 concorrunt beeps then:

1. Press and hold the power button so the fan goes off.

2. Loosen the 4 screws mounting the RAM holder slot a bit.

3. insert small folded paper or old credit card cutting as plastic swag/cuff

4. Power your Mac. [If this works, Hurray!! Close off the lid and get back to work] If this doesn’t.

5. Tight the 4 screws, arm your Mac. This should make it work, i suppose.

6. If it does work, thank me @bakedsamosa and iFixit for simplifying the replacement.

7. Close the Lid already. Getting back into service Steve Job’s best creation.

Yes, I did have the same problem and i resolved adjusting the Memory Ram

Same problem my macbook could not start and beeps three times. i removed both Rams and put them back there and Voila it starts and no more beeps

After I checked on the ram the sound did not stop so I had to disconnect the internal battery and reconnect it. that worked for me.

I removed and replaced them a few times, both worked on their own in the top slot but if one was in the bottom it did not work. no signs of corrosion so not sure what is going on with the bottom slot

In my case is was RAM not making a good connection and this solution solved the problem :
Getting three Beeps, Not RAM error
I added a piece of foam between the RAM modules and the case that push the modules down gently.
