The computer I picked up is a mid-2012 MacBook Pro by Apple it is the A1278 model with a logic board number of 820-3115-B, and it comes with an i7-3520M CPU and 8 GB of DDR3 RAM – however, the hard drive was taken out of the computer by the time I received it. It certainly didn’t look particularly promising, but I felt it would be a good way to test my skills in component-level repair – with a pretty nice prize if I succeeded.

It had a note attached to it citing several issues with the computer: the display doesn’t work, the battery doesn’t charge, one of the USB ports doesn’t work, and it won’t load an operating system.

A couple weeks ago, I picked up a dead MacBook Pro that was on its way to the recycle bin, and was curious as to whether I would be able to fix it.
