Macbook Pro screen glitches, 3 beeps, NOT THE RAM

Just to make life easier.... here is the link for Apple product feedback. http://www.apple.com/feedback/macbookpro.html

The comment box has limitation on character so you need to be really concise. People need to give feedback as much as possible for Apple to pay attention to the defects of their product...

Hey!

I've been having the same problems with a mac book pro mid 2012 since I updated the original RAM to 16GB. The computer crashed on every test I ran with Rember. When I changed back to the original sticks, the problem was still there.

However, I noticed that the computer freezed (with weird colors on the screen) when the computer was physically moved! So I opened the computer again and made **** sure those sticks was inserted as far as possible into the RAM bay. The computer hasn't crashed since.

regards,

Riberr

exactly same problem with my Macbook pro 13' mid 2012. i7 2.9Ghz

I'm pretty sure I just started getting these problems. Have the same specs. Upgraded the RAM about two years ago I have one 4GB in each RAM slot. I also provided feedback to Apple. Really don't want to put more money into this computer.

My problem is when putting pressure on the bottom left of my computer or anywhere around that area it will freeze, sometimes glitch the screen, and then shut down. I only heard it beep three times on start up once and it was sitting in one place for a long time before that happened.

Have you checked your battery?

Same problem here...

Just sent feedback to apple. Hopefully something happens. Already replaced my RAM and SDD in the course of finding a solution. If anyone finds a solution other than removing one RAM from the slot, please report! I'd really appreciate any help!

Just FYI: I had a Macbook Pro before with a known issue with the graphic board. Apple knew about this issue and had a replacement program for the affected Macbooks. But since the issue with my old Macbook occured only 3 weeks after the program ran out i didn't get any support anymore.. I tried to talk to Apple about this but there were no gestures of goodwill. So I'm not very optimistic with this know...

How long did the replacement program run? Usually that is at least 2 - 3 years. Why didn't you take in your machine for a free repair?

And, have you checked your battery?

Thanks for the fast reply!

The replacement program ran for 3 years I think. But in my case the issue occurred about 4 or 5 weeks after the program ran out. I took my Macbook to Apple but they were not willing to accomodate in any way. Please don't get me wrong, I just think that if I buy a product that costs that much and there is a known issue like this, the company could at least be cooperating a little bit (even after an official program ran out).

I had my whole my whole Macbook Pro checked. They suggested the harddisk and RAM replacement. Battery was also checked.

I had the same problem, and it was resolved by removing the RAM closest to the motherboard as suggested... What is really peculiar is the fact that I can use both RAM slots again after i installed Linux instead of Mac os.. So we must conclude that it is a software problem disguised as a hardware problem... shame on you Apple!

Exactly same issue (three beeps with screen issue and shutdown), with the exact same fix, MB Pro mid 2012. Take the RAM out, replaced both still did not work. Left the bottom out just replaced the top and everything is back to normal. I ended up replacing the top with an 8GB so I did not lower my performance from my two 4GB I replaced.

Sadly on my less than four your old machine this is my third part failure and this machine is only used at home. The drive two years ago, something else the year before (another known issue) and I think I'm at least on my third charger. Disappointing to say the least.

I wanted to give my experience with this glitch so far-- I was trying to troubleshoot some crashing and visual glitches that were intermittent, I eventually heard about the GPU bug and thought that was potentially it, but I was getting the 3 beeps sometimes, and I was getting it specifically when I tried to enter diagnostic mode while holding D on the keyboard during startup. Despite this, I am still getting the intermittent visual glitches as well, and I was hoping my computer had the GPU issue since that is covered under the apple extended warranty program for my model of macbook pro, thankfully.

Well, I took it to the apple store and they ran their video diagnostic twice in a row, and it passed both times. The tech really wanted to help me get the free logic board replacement, since it was the 'simplest' for me and obviously free, but he said they couldn't do it unless they could see the computer's GPU fail in some way. I told the tech I think I could get it to happen if I put the computer under some stress, so I booted into OSX, did a few things, and within probably 5 minutes I got a grey screen of death, proceeded by an unresponsive image of the desktop as it was the moment before the grey screen, but with tons of visual glitches--- success!! That's what they needed, and once the tech saw that, he was more than happy to place an order for a new logic board for me. They didn't have any in stock, so I took the computer home. I had also ordered 2 sticks of 8gb of ram a few days before (only 60 bucks on amazon right now) and they just arrived. I ordered them when I first heard the beeps, not knowing it was the ram slot that might be bad and not the ram itself. I just replaced the 2 4gb sticks with 1 8gb stick on the first ram slot, and everything seems to be working fine tonight. So for now I have a working computer using only 1 stick of ram, and I will get a new logic board within a week or so, and then I will insert the other 8gb so my laptop will be better off than it started.

My advice for anyone who thinks they might have this RAM bug and are also experiencing visual glitches is to wait until the computer visually shows the glitch and take it to the apple store then, or be very confident that a visual glitch will happen while you are there, because even if the computer passes apple's GPU test, they can still do the free repair if there are any visual glitches during the visit. Whether my issue is the GPU or the ram I do not know, but the logic board replacement which should clear up a bad RAM slot issue as well. Let them know the bug is intermittent and it might take some time to reproduce, and you should get it fixed free.

Exactly the same issue with my 15" Mid-2012 MacBook Pro. Started happening a few months after upgrading to 16GB. Returned to stock 8GB and issue persisted. Took to apple store and a test identified my SSD was failing, replaced it but issue still persisted. Then I found this post. I get a variety of types of crashes, some bar code like, some feezing and other just a random reboot. All result in three beeps. It can take up to 15 restart attempts to get past the beeping and get the system back up and running. Unlike others, I can't seem to consistently replicate the issue with pressure, though it has happened when carrying my laptop about.

Like other have suggested, please report this issue to apple. http://www.apple.com/feedback/

One thing to note is that the MacBook Pro Repair Extension Program for Video Issues is only valid until the end of 2016. So bombard apple with feedback sooner rather than later.

My next steps:

Film the bar code graphical crash happening. Bring it to an apple store, show them the video and try to recreate it in store. I plan to then show them this forum thread and explain the extension program and just hope that they fix it for free as a gesture of good will. I am based in the UK and will let you know how it goes. I'm moving to Canada next month so if it fails I will try the same thing there too.

Hey everyone,

It seems to me like because this is such a long running problem, and all of these errors have occurred on our 2012 models (yes, mine included) and this thread has been going for over 2 years that maybe Apple were aware of a problem but because it is for a model computer so old they really can't do much about the issue.

My computer just had this problem last night while I was playing LoL which I do on my MacBook occasionally. However, unlike the screenshots on this thread my barcodes were pink and I wasn't sure if anyone else had the same problem as well. Also, the three beeps of death did not happen every time the glitched screen came and for me the beeps only happeNed after the fourth screen glitch and happens every second time now.

Also, for the last couple of months every now and again I would get a single barcode line, usually pink or green in a random area on the screen. This had absolutely no effect on how the computer ran as I could just swipe desktops and it would go away, however I'm beginning to think it may be related as it had the same barcode glitches, if anyone else had the American problems or experience with me please do let me know.

I Also think that this has a huge part to do with the overheating, as it only originally happened when I was on LoL in load in, whereas now it happens if I move the laptop suddenly or if my fan is going full blast and the computer is boiling hot. If someone has a similar experience as me and have a solution that would be a great help, and I will be investigating smilingeyes' solution as well, but probably with an alternative as I do not have any of that type plastic just lying around at home.

thanks for the help and time in the previous posts guys, and hopefully one day Apple will provide us with an explanation

Bumping this (is that still a thing). Curious if those who have gone with the "top slot only" solution to this problem have had it work LONG term.

I just removed the bottom slot module taking my computer down to 4G RAM, and so far today it looks okay. I will leave it like this a few days and report back. In the meantime, I wonder if a few of you others would as well. Thanks.
