Error Macbook Pro (2012)

[RickM123]

Hi Everybody,
Since a few days my Macbook Pro (2012) gives some kind of error when I pick my macbook up on the bottom. Check the screenshot in this post.
I think it has something to do with the working memory slots.
Do you guys know how I can fix this?

What model (Retina or not) and size (13" or 15") do you have? There can be a problem with the 2012 Retina 15" models - take a look at post #6 of this thread:

Its caused by the logic board shorting because it in some way flexes and touches either some part of the topcase or bottom case. I've heard of people having multiple ship out repairs fail, but hey, if Apple messes up enough usually they replace the computer meaning you'll get a brand new one for the cost of a repair.

I had this issue on a MBP 13" mid-2012. Nothing else I tried worked, until I removed the memory stick from the slot closest to the keyboard and left it empty. Have not had the issue since.

Was this really an option to you? I have just 8 gb of RAM in total, so when I remove one of the slots it's really slow.

Just to be clear, you have a 2012 non-retina MBPro with removable RAM and drive, is this correct?

Could it be -possible- that when you put a little pressure on the back cover (by picking it up), contact is being made with the RAM DIMM? Not much "deflection" would be necessary to make things go awry.

I've been seeing a number of posts from folks who have non-retina MBP's, and have "memory slots go bad" on them. I'm wondering if this could be a problem with "movement" or "flexion" of the back, pushing on the RAM DIMMs? (I could be completely off-track here).

Here's what I'd suggest for you:

First, remove the "topmost" DIMM (the one that is "closest to the cover").
Even if it's slow for now, close it back up and run that way for a day or two. Do the screen errors go away after you do this?

If so, I would consider doing this:
1. Buy ONE 8gb DIMM, and put it into the LOWER slot. I would leave the topmost slot EMPTY. That should give you enough RAM to do most things.
2. Do you still have the original platter-based hard drive inside? If so, REPLACE IT with an SSD. Things will IMPROVE GREATLY (I cannot overemphasize this). It's easy to do (since you already have had the back off, it's child's play).

IF running with the single (lower) RAM DIMM solves the screen glitches, the SSD will breathe new life into the MBPro and remake it into a good performer for the next 2-3 years.

Additional EDIT:
The 2012 MBPro 13" models also have a problematic hard drive ribbon cable. If the cable starts to go, communication is lost momentarily between the drive and the motherboard, and it will mimic the symptoms of a bad OS or failed drive (but it's just the cable).
Apple (for a time) had a free replacement for this cable. Not sure if that's still in effect.
Do you have a brick n mortar Apple Store near you?
If so, make an appointment with the genius bar, and let them check the cable for you (perhaps test the RAM at the same time).
