Macbook Pro screen glitches, 3 beeps, NOT THE RAM

Just had the same thing happen to my MacBook Pro. It's a 13" mid 2012 with 2.5 Ghz (the logic board is MLB, 2.5Ghz). I was running fine this morning then the screen just corrupted (as per everyone else's screenshots). I tried to reboot and got the 3 beeps issue. Had to do a 10 second power button + cmd + ctr + shift. It then restarted but since then it's barely usable. It's only 16 months old!

Took it straight to the Apple Store (as it's my work machine and I need it urgently). They couldn't even run their test suite without it crashing. They're going to replace the logic board as it looks like a GPU issue. The quote is 4,486 HKD which is a 580 USD!! That's over double what some of you guys have been reporting. Whilst I'm obviously annoyed that this seems to be a general hardware issue with MacBooks and Apple should be recalling them, I'm even more annoyed that I'm getting charged > 2x for a repair. The cost of living out here certainly isn't 2x that of the US (if anything many things are cheaper!). Plus the components are likely all manufactured in China anyway!

I'll be lodging a complain for sure about the price. I wonder if there's anything we can do about the fact lots of people are facing the same problem. Any ideas on a head count for this? And what sort of head count actually embarrass Apple enough to do a recall?!

I brought my machine into an Apple store yesterday and they were unable to find anything while running their tests. I'm going to try and change out the ram to see if this is an issue. Really it seems to me the ram is fine however there must be a loose connection somewhere as this issue with screen lines and shutting down only occurs when I move or pickup the laptop. Very strange, I'm using it now and typing on it just fine on a table.

Confused and a little bummed.

Replaced the RAM in my machine and have not been able to replicate the screen freezing, grabbed 2x8gb PNY Sticks (replaced the Samsung memory I had in there). If the issue comes back I'll let you know!

Hi, rutheone

how is your macbook? did the problems happened again or everything is fine until now?

Having the same situation here. Macbook Pro 13" mid 2012. 8GB of RAM, i7 2.9GHz and 1TB HDD.

Really upset. Screen freezes and this weird lines show up just like this print screens.

Yesterday i changed the 2x4gb sticks to new ones. Until now, nothing happened but i hate this random issues. I can't know if it's fixed or isn't. I guess all i can do is wait to see.

Sorry for any mistakes in the text, not a native speaker.

All the latest guys on this thread. As far as most of us are aware changed the ram doesn't help anything. The problem seems to be 1 or both of the ram sockets. I solved my same problem by taking out the bottom ram completely. I only upgraded the ram to get more power. I have had no problems since I done this. I know it's not perfect but at least my mbp works again problem free for now. Open up the back and see which socket is causing the problem. Hope this helps.

Since replacing the ram I've had two hard restarts (your mac has restarted because of a problem - screen) and then it boots. I've yet to see any lines on the screen come up like it did in the past. I can pick up the laptop without this issue occurring unlike before it would freeze and give me the lines instantaneously.

The ram seems to have helped however with these two hard reboots I'm beginning to wonder if it is my SSD (no reported issues on amazon of the model I have and it has a ton of reviews).

I did call Samsung about the ram that was in the machine and they said because it was OEM, they couldn't warranty it and to call Apple.

If this happens again I may throw back in the old hard drive (and I shudder saying this, it was so slow) and see if that helps.

My last resort is to replace the logic board, but I'm not going there just yet.

Mid 2012 MacBook Pro.

it seems to be the RAM sockets since using it with only one stick of ram seems to be the best solution right now. From what I've read from everyone here it seems to be the socket closest to the board.

Hi everyone.

So glad to find this thread finally. I've been looking in French forums for one month without finding any answer relevant to my problem. I have the same MacBook Pro mid-2012 and the problem happened about one month ago (I have the MBP since 14 months). Then it became worse and worse. The first time the freeze with 3 beeps happened, I brought it straight to the closest genius bar to check. They said it was RAM and asked me 300€ to repair it. I refused and brought it to the Chinese store to test my ram. He said everything was fine. Now, the problem is still going on and I see it's a really recent problem. I agree with people saying that when we press where RAM is (while using the computer) it will crash. I observed that sometimes when I plug my earphones (after one hour using while charging, so it's a bit hot), it will crash also. I am so desperate about this problem since I use it for working!! And I trusted Apple so much after using iPhone for 5 years, I thought would be really nice. Hope this problem can be solved soon!! Because even the Chinese don't know what to do.

I also noticed that my computer was crashing when I occasionally play LOL and become really hot (that was at the very beginning though but it occurs from time to time).

please find a better solution than removing one bar of RAM.

I have the exact same problem with a mid 2012 Macbook pro 13 inch!

Since I upgraded the software it started with simple freezes and restarts, and now the screen scrambles and beeps like its going to explode...

Hi!

Been having the same issue since Q3 of this year. It started from occasional static glitches (freezes) that leads to reboots, then not long lead to random reboots, blackouts with the 3 Beep warnings (RAM problem from what I learned). But after I get through, the laptop works. Having only the fear that it will reboot randomly and distract my work. I use my macbook for playbacks and documentation work. (Occasional games). I've had the issue of when moving from one place to another which "shakes" the device even the slightest makes the glitches then reboots, at times without having done anything, when closing the laptop to sleep and waking it up which in turn doesn't wake up but reboots, pressures on the lower left triggers the glitches.

I've modded my device to an SSD and 2nd HDD prior to the problems. Works fine the first 6 months then the problems occurred right after upgrading the software. Discovered the Ram Issue (3 Beeps) then decided to upgrade to 16gb (8gb/slot) but still experiencing the issues.

REALLY DESPERATE IN FINDING THE SOLUTION!

I've been in circles now for 2 months finding a solution.

Right now, I'm following the 1 slot fix. Hope it works somehow.

Hope some from apple fixes this.

Thanks!

Update:

Did the 1 Ram fix (Top Slot only). Shook my laptop, added pressure to the left side.

Not issues.

Yet...

Yet another person here with the same issue!! My macbook is from 2012 as well. About a year ago it started doing all the lines and beeping and what not and eventually wouldn't turn on anymore so I gave up on it. I just recently gained the confidence to do some troubleshooting and RAM switching. I too found that taking the bottom ram slot out (closest to keyboard) has worked so far for me.

I think this is ridiculous that this many people have the EXACT same issue and it isn't recognized by apple as it is clearly a flaw on their part.

I also have the same model (Mid-2012 13" MBP) and the same issue. Mine first happened 8 months after purchase, and they replaced the Logic Board and hard drive. Then 10 months after the first repair, the same problem occurred so they replaced the Logic Board and RAM. That didn't fix it either because 13 months later the same problem is happening. With two new Logic Boards, a new hard drive AND new RAM, obviously there is something clearly wrong with the actual manufacturing of this model rather than the individual parts. I would not bother paying $280 to replace/fix anything for the laptop as the problem will probably persist again eventually.

I have no idea what to do at this point as Apple won't give a full body replacement since they don't recognize the problem. How many people have to report this issue in the feedback forms for Apple to recall this absolute faulty product?

Are the RAM replacements and upgrades and such mentioned earlier in this discussion forum working? I feel skeptical even bothering to change any parts in my laptop as Apple themselves failed to fix the problem at hand after replacing the Logic Board twice.

I am exactly in the same situation you are. My computer is behaving exactly like this. I also bought mine in 2012 (October).

Did you manage to solve your problem, in the meantime?

I used the link you provided. I hope they decide to do something about this.

I just did the same, left one slot memory free (the closer to the keyboard), and issue has gone.
