    I happened to be walking down a street and found a mid 2013 Macbook Pro someone had thrown out. I didn't expect anything to work on it. The bottom panel was detached and seriously dented. I booted it as soon as I got home and it turned on! However at first it seemed as though the battery didn't hold a charge and the backlight for the screen is completely dead. I managed to reset the admin password and noticed that the cable from the battery to the logic board had been detached. So I plugged that back in and the battery works! From what I can see, everything else works too (wireless card, ports etc.). What a find!

    Now the only thing that remains non-functioning is the screen. I'm using an external LCD which works fine, but I'm hoping I can turn this former piece of garbage into a fully functioning laptop. I'm wondering, does anyone know how I can repair this screen and is there a possibility that it's simply another cable that's become detached. As a reference, there is no physical damage to the screen that I can see. It's fully intact and it works, with the exception of the backlight. I'm thinking it could be a logic board problem too (hopefully that's not the case), but either way I'm ecstatic to find a near fully functioning laptop.

    I'd say find some repair shops in your city and call around for a price. Indeed, an excellent find.

    If push comes to shove, hook up an external drive and it'd make for an awesome little Mac Mini-esque home server.

    Nice find! In this case I think iFixIt is going to be your friend.

    Probably thrown out because the screen was toast.

    Nice, good for you! My neighbor recently gave me a mac mini with a dead hard drive, I replaced it with a 240gb ssd and since I did that the machine is powerful enough for what I need it for. Thank you Patrick (my neighbor).

    Thanks for the input guys. A quick update, I ended up getting a pretty decent deal on a logic board repair from a local shop. It's now a fully functional laptop and in great shape!

    Awesome. I got a MacBook from one of our kids who discarded it because it was flakey and missing a key. I replaced the hard drive after reading up on the procedure, bought OSX, and got the Genius Bar to help me flash the OS to it while on a business trip, then got a new key from somewhere on the net. The thing has worked fine for three years through all the subsequent OSX updates.

    Check voltage on pins 3-4 of LCD connector. What do you get? 0v means usually blown fuse, 8v means blown feedback via most times,bad bkl_en resistors, bad led driver. over 30v means someone screwed up replacing the screen and didn't plug the backlight ribbon in.

    edit, just read that you already replaced the board. :(

    what did you do with the old board?
