This board is WORSE!Ĩ20-3330 2012 will fit but require you mess with the LVDS cable to get it into the connector, which is slightly different. Short story before dan calls my sentence noise, 820-2850 is junk to be avoided at all costs. You can just chop up the connector and splice the wires from your battery onto the connector of an older battery, but this is a pain in the 820-2850 also have rampant kernel panics due to issues with VRAM pgood signals and other that is too much to mention here. This board is bad.Ĩ20-2850 2010 will fit, but only if you get the older battery.

The boards available have already been used for 2-3 years, and the replacement chips are harder to find new, so more people will be advertising 'repairs' for this board that don't actually work more than 2 months, because they are not using new chips. It will fail every 2 to 3 years, and only get worse as time goes on. Mine was a 15in display, but I don’t see why this process couldn’t work with a 13in (you can never research too much).ĭefinitely cheaper than purchasing an altogether new system and the upgrade/repairability factor of my unibody (A1826) makes me think I'll have it around for a while longer.Ĩ20-2915 2011 is what you have. I don't think anything in my system (aside from the magsafe adapter, battery, speaker, and display) is the same as when I first purchased it. So YES, it is totally possible to interchange the unibody logic boards (at least early 2011 to later 2011 or 2012) if you are so inclined.

Needless to say, I was very happy with my current array of upgrades: 2.3 GHz > 2.6 GHz, USB 2 > 3, bluetooth 2.1 > 4, Radeon 6750M > GeForce 650M, RAM: 16GB and the HDD(s). Even the cables to the fan that I had broken (I pulled instead of lifted). The rest of the ports, cables and screw holes lined up perfectly. Turns out super glue is non-conductive so it was perfect solution to hold down them down so I could apply some thermal paste. I cannibal-ised my old system, popping off the screw-holders used on the old circuit board and super-gluing them to the new one in the same position. It could have been the supplier I chose or possibly these models don't heat up as much, but the new board didn’t have screw holders like the old one did.Įither way, I came up with a solution. Apologies for the slight distortion, I imagine the photographer was at a slightly different angle when he/she took the photos:Ī minor issue popped up when I was re-applying the heat sinks on the USB controller and the platform controller hub (assuming the heat sinks are necessary on the 2012s). This is an overlay of the two logic boards using photos of the iFixIt teardowns (with a grain-extract filter thanks to Gimp) and there seem to be no real connection issues. I placed my order for a logic board but I was still a bit worried so I got board (hehe) and decided to see if there were any significant differences. For the life of me, I can't see why this 'upgrade' wouldn't work, and the iFix it forums have instilled some modicum of confidence in me… I decided to try it!

I was actually amazed that there wasn’t more information about this kind of thing on the internet (with all the menial stuff like hacking your xbox and tricking out your iphone).

I heard from a repair shop guy on e-bay who said the upgrade wouldn't work (but I think he was just trying to sell me his repair services). The iFixit teardowns and logic board replacement guides for both models (2011/2012) seem identical along with all of the tech specs about the wattage/voltage/etc. I found a decent deal online but I couldn’t find anyone who ever tried it. figure that one out) and the upgrade from USB 2 to USB 3 ports.

This is a slight edit considering I browsed through my old answer and even I found it a little confusing: I had a logic board accident with my early 2011 MBP, model a1286 and was thinking of replacing it with a Mid-2012 (non-Retina) board for the CPU/GPU boost (I'm a gamer and a Mac user.
