The warning regarding tearing of the cable cannot be overemphasized. I tore a brand new cable on installation and had to hang my head in shame after having to reinstall a broken screen until I got another new part.
This guide was a life saver. I had an issue with my machine randomly shutting down. I took it into the repair centre who diagnosed a logic board failure and it “wasn’t worth repairing”. That is not an answer to me. I sourced a refurbished logic board and installed it. But my problem didn’t go away. I then realised I had over enthusiastically cleaned my keyboard and shorted the power button, which kept causing the machine to shut down. I learnt this after ‘jump-starting’ my Mac without the cover and it ran for days without issues. After reconnecting the cover, my problems started again. A new cover from iFixit sorted everything out.
This is an awesome guide. My girlfriend’s MacBook Pro was diagnosed with a logic board failure by the repair centre. The repair cost was going to be more than a new 6-core Mac Mini.
I tinkered with the device, and thanks to the help of the iFixit community, a battery fault was diagnosed. Installed a new battery and the problem was solved!
