For step 5 and 6, maybe a reference could be added to a screwdriver for the Tri-wing screws - this seems quite difficult to find (and in the right size...).
Else I agree to what was said before - an excellent guide!
ifixit does it again. Thanks so much for making this resource available. Macbooks are so expensive and its great to be able to fix them and keep em going.

where's a good place to find decent condition logic boards My son was in Afghanistan and there for a long fricking time. While he was gone I had gotten him a MACBOOK Pro 15 loaded anyway It was made in mid-2012 He didn''t even get to use until he was home in 2015 and I hadn't used it. after a couple months he got the froze gray screen with apple logo. Called apple did every single thing possible. Finally they said bring into service center. I did they said would have to go in for repair and wasn't a retina display so I would have to pay . They couldn't tell me exact cost but esitmated at oveer $500.So I googled and I guess it's the graphics which you'd need to replace LB what do you think? Is there another fix? I can do work on windows stuff all the time just never Mac this will be my first. So need good sources if you can help I'd appreciate it. Russ
I have what appears to be a slightly different mainboard from all 15” unibody models. Could anybody help me identify my mainboard and maybe point me to the fuse for the LCD display back light ?
holy moly!!!!! i did it!!!! thank you TEAM iFIXIT!!!!! my mbp15 uni mid-2012 is once again a laptop, once again a computer, once again a tool for my art. Apple Store was going to charge me a lot, more than a replacement logic board, “if they could get one”. since i had done the fan on a 2009, RAM on the 2009 and this machine, and tightened up the screen hinge on this one (i bought it “refurbished”, turns out it has broken battery mounting lugs and was missing a hinge screw), so i figured, wth, lets do this. weeks of hemming and hawing, and i finally ordered the board for ~ $350. spent the morning working on it, forgot to latch the keyboard ZIF, so i had to backtrack, but otherwise, it works. the only thing was that i have to do a whole new backup (Time Machine), in progress now. now iʻm saving money to get a new battery and 1TB SSD, which should be a breeze after doing the logic board. gonna rehab my partnerʻs old white machine (2004?) sometime. one happy and relieved kitty girl here!!!!!
