MBP 13" mid 2012 2.9Ghz here.
Still a great machine, and as I use it as my main workstation (also for photography post-production with photoshop and lightroom) I modded it a little bit: expanded RAM to 16Gb, and most of all, added a SSD disk for the system, and an optibay for storage disk (initially the original 750Gb HDD, now I got a 2Tb disk).
I've had a long series of issues with this machine, especially after the optibay.
I once had to change the disk cable connecting the SSD as I was getting a frozen system and the damn spinning beach-ball.
Around January I started having stability problems, and troubles with high percentage CPU usage.. and I tracked all down to being a failed (no brand) optibay adapter. Solved by getting an OWC one.
I think about in the same period I've lost one key on the keyboard: the n key, and only that, doesn't work. I thought it could be related to the optibay issue maybe, but it looks like it isn't. Haven't found a way to fix it and I do have to paste the n each time I need it (pretty annoying).
Another problem I have is... sometimes I have sudden shutdowns. I think there are 2 causes for this
1) Sudden Motion Sensor might have caused troubles on occasions (the mbp was often shutting down after a quick movement). I think I fixed this disabling SMS.
2) the SSD disk cable might have issues again - I realised this because today I had opened the MBP while it was playing some music, just to remove the bottom in order to fix a broken rubber feet, and it shut down immediately when I slightly touched the disk cable. Also it shuts down sometimes when there's too much pressure on the bottom-right corner of the mbp (ie: I rest my wirst there, or I grab it from there to move it), basically where the cable is. I guess too much handling of the cable (when I was having the issues with the optibay adapter I had made many tests mounting and dismounting disks) might have weakened it.. but also I realised it lays over the optibay adapter, exactly over a little circuit where there's a little soldering bump, and I can see signs of the bump on the cable.. so I guess I better get a new cable and put something soft between the cable and the bump.
All this is just to describe all the little troubles and frustration I've had so far.
Last problem I'm having since a couple of days is the cmd+v I use for pasting the n doesn't work anymore... or better: it works rarely with the left "cmd" key, and always with the right one. The v itself works fine, so as both cmd keys (I can see a feedback in the virual keyboard even when I press the left one, plus it works for cmd+c). I find this very strange... and I really don't get it. Any clue? Do you think it could be related to the cable problem? Or with the n key problem? I would love to fix all these little troubles, including the n thing, as I think the computer would still work well for a few years...
Thanks for any help!
