MacBook Pro 13" Unibody Mid 2012 (2.5 ghz) Hello, Thank you for reading my question. I have a MacBook Pro Mid 2012, a month ago it started with the beep code and I reseated the Ram. The Macbook worked just fine again. Some days later I had to transport the MacBook in my hands while it was on and I saw some graphic failures on the display and the system froze. I had to restart it and everything was fine. It happened about 10 times the last days/weeks. When the failure occures it´s always when I´m applying force to the housing of the MBP. Now, I think I figured out whats the problem: The Ram socket on the downside has a connection problem when im applying force to the housing or the socket itself. If I use the other socket there is no problem. I also tested the other Ram module. It is the socket. After all this trying and figuring out what it could be I still don’t know what to do now. Do you know this failure? and what could I possibly do to fix it and use 2 RAM modules again (now Im only using 1 because of the bad socket). Regards, Alex
Sadly, there is little you can do to fix this your self. It sounds like you isolated the problem down to the socket which is part of the logic board. The only option here is to replace the logic board which is expensive! The other direction here is to live with the single RAM module and get a bigger module to offset the other sockets missing memory. That is of course one that still will work in your system.
Hey everyone, after having this problem, i found out the problem might not be the soldering at all. read on… I have a MBP 15" early 2011, had the logic board replaced in the apple program for the video chip, after that, i started to get kernel errors once in a while, all was pointing to RAM, but could never actually find a defective stick and tried many, after a while of seating and reseating the sticks and a fresh install os the macOs it stopped for almost a year with no problems i thought i was done; only to begin crashing, powering off and beeping this week. i’ve been reading forums about this problem and after watching this video https://www.youtube.com/watch?v=xpagfXra… I’m having exactly the same problem as this. So I took it apart again, and what did i find… apparently, as i said, and for everyones happines it migh not be the soldering at all!! It seem the CLIPS that hold the stick closest to the keyboard are worn and do not have enough pressure so they do not hold the ram in place all the time, a little bump and the RAM stick springs up like half a milimeter and the problem appears. What did i do? Got a 1.5mm (.60 cal) piece of flat styrene about 3mm wide and 7 or 8 mm tall, put BOTH RAM sticks in place and with a little plastic tip/spudger push down the stick closest to the keyboard so the clip can make its full travel inward and insert the styrene pieces one in each side in the slots between the clip and where the screws for the bracket are and then push them towards the RAM contacts to make pressure inward so the clips are pressed firmly against the sticks (you wont be able to remove the sticks without removing this styrene pieces).
I did this, the MBP started with no problems, i can now shake it and won’t freeze and/or beep at all. I’ll try to make a video or at least a photo guide showing what i mean and post the link (it will be my first YT video so be nice hahaha) so it shows the fault and fix clearly.
I’ve got exactly the same problem. Reading around there seems to be at least a few people who have crashes when carrying the laptop (holding it on the left-hand side - which applies pressure to top of the RAM slot). I wonder how many people have had this problem and never realized it. Bottom slot is damaged for me too.
