No power to the laptop? Replace the DC-in Board.

  1. Remove the following 10 screws securing the lower case to the MacBook Pro 13" Unibody:
    • Remove the following 10 screws securing the lower case to the MacBook Pro 13" Unibody:

    • Seven 3 mm Phillips screws.

    • Three 13.5 mm Phillips screws.

    Compare the short screws carefully before reinstalling them. The shouldered screws go in the holes on the front edge.

    Before I started removing any screws I took a piece of paper and drew the bottom of the laptop and put a piece of double-sided tape in the spot where each screw goes. That way when I took out the screws, I could put them on the tape so I knew exactly which screw went in which spot. I did the same thing for dismantling the inside on another sheet of paper, then a third sheet for the screen after getting the front glass off.

    I use a similar technique: I print out the iFixit manual for the job, and Scotch-tape down the screws/brackets/cables I remove at each step next to the component descriptions. That way, when I'm reassembling, the bits are taped right next to the photo of where they came from.

    That's exactly what I do for all my repairs! It's the best way to keep track of all of the parts ' original location and to make sure that you don't miss any parts during reassembly.

    Great idea and one I use often

    Thomas Overstreet -

    Excellent idea! Thanks for sharing it here.

    I used a 00 that fit but the screws were very tight so I used a tiny paintbrush with some wd40 on it and put it around the edges of the screws. Worked like a charm

    • Slightly lift the lower case and push it toward the rear of the computer to free the mounting tabs.

    In the introduction you should link fixers to this excellent doc: https://www.ifixit.com/Misc/HD_Software_...

    It is really critical, super easy, and free(!) to clone your existing drive onto the new one you will install. I ran into one error, but SuperDuper! support replied immediately on how to fix it...Thanks ifixit and SuperDuper! (I ponied up the $28 for the software anyway, I was so impressed!)

    why is step 3 necessary?

    Just to disconnect any power source to avoid damages by short-circuits.

    How do you get that battery connector back on? Do you just press it in back in place after you're done?

    Horace Chung - Antwoord

    yes. I usually plug it in before I screw it down so I can lift the battery a bit and have enough slack to be able to go straight down on the connector, otherwise it comes in on a bit of an angle, which can't be good (though not necessarily bad).

    This step almost finished me, and I did extensive damage to the battery plug. Fortunately, I later replaced the battery, and the replacement came with a new plug! :) Newbies need to know - 1. The battery plug is like a thin lip on a thicker lip, so you need to pry BETWEEN 2 thin lips to get it off, else you are trying to yank out the socket. 2. Mine was initially VERY tight, and trying to get it out broke the plastic on all sides of plug, even though I was as careful as possible. Luckily, this didn't hurt functionality and I later replaced the battery. AFTER disconnecting once, it was never so tight again,

  4. Use a spudger to pry the fan connector out of its seat, and straight up off the logic board. It is useful to twist the spudger axially from beneath the fan cable wires to release the connector. The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

    I just soldered it back on. . . I tried to clean the pads with braid first, but it didn't do much so I don't think that's necessary. I first supper-glued it in place with the pins on the pads and then I put a tiny dab of solder on each pin/pad. Plugged in the fan and i works!

    Just the answer I was looking for Ron! Awesome work buddy!

    lucasjmenzie -

    i recommend not to use the spudger. you damage more than by unpluggin the plug by hand. just simply pull the cable close to the plug of the old fan softly upwards out. the plug than comes easily out. put the new fan in and push the new plug by hand in. it is much easier than using a spudger. i also started with a spudger but nearly broke the plug out, so i watched a youtube tutorial and learned about it…

    If you only want to replace the DC-in board, stop here and GOTO 17 (and DO NOT 4 and 6).

    When the Logic board is loose, lift it up on the Harddrive end and shift slightly towards the HD, so that the USB connectors at the outside come free from under the case rim and the board can be lifted up a bit. Then there´s enough room to move the DC in board, pull the cable out with a pair of tweezers, wriggle it out from under the microphone cable and wriggle the new connector in. It can be pushed into the socket with tweezers or a small screwdriver. This worked perfect for me.

    Be careful not to bend the logic board, but otherwise I think there´s much less risk of messing anything up with all the connectors and bits and pieces that need to be loosened and fastened.

  10. In this step you will disconnect the camera cable. Most machines will have a small self adhesive plastic retainer stuck to the logic board to keep the connector in place. Before disconnecting the cable, be sure this retainer is moved out of the way.

    • Pull the camera cable connector toward the optical drive to disconnect it from the logic board.

    • This socket is metal and easily bent. Be sure to align the connector with its socket on the logic board before mating the two pieces.

    There is a small piece just below this connector which is just an adhesive block to keep the connector from coming out. It is easiest to peel it up first with a fingernail or spudger then remove the cable. Likewise reinsert the cable before reapplying the adhesive safety stop.

    I couldn't reconnect this cable correctly, so my camera is not working anymore.

    It doesn't matter to me, I didn't used the camera that often...

    But the Ambient Light Sensor uses the camera to control keyboard lighting, so I wasn't able to see my keyboard in the dark anymore... :(

    If you have the same problem, after a couple of google hits I've found this app: https://www.macupdate.com/app/mac/22151/...

    Problem solved! YAY!

    PS: be careful because WIFI passes through this cable as well!!!!

    Look at the photo intently. The connector is inserting not in parallel, but at a slight angle. The bottom corner of the connector is slightly ahead. It is important! Singular metod to insert it.

    When reinserting the keyboard ribbon cable, make sure you push it in all the way (two plastic tools are helpful - one to push it down flat, the other to coax it all the way in). For 3 days after replacing a top case, my MacBook Pro 13" wouldn't start up. I thought the main logic board was fried too. However, reinserting the keyboard ribbon cable again, this time perhaps 1mm farther in, and it started up again! I did the same for the "keyboard backlight ribbon cable" (i.e. reinserted it just to make sure). Really not sure which completed the circuit so is would start, but I suspect the keyboard ribbon cable.

    I usually use a piece of sticky transparent office tape and stick it over the flat cable a bit further away from the mating part then pull on it. There is no better way to force the flat cable into a stiff connector without damaging the fragile cable.

    Leo Bodnar - Antwoord

    As others have stated, if the keyboard ribbon cable isn't fully inserted the MBP will not power on. Leo Bodnar's recommendation to use a piece of transparent office tape did the trick for me. Many thanks Leo!

Conclusie

To reassemble your device, follow these instructions in reverse order.

84 andere personen hebben deze handleiding voltooid.

Reassembling: Make sure, the cable of the DC-In board is on the logic board-side of the screw hole when putting in the logic board. Otherwise the display data cable bracket won't fit in and you have to remove the board again.

So I hope, the DC-In board was really the cause of my problems. I changed the battery and the charging cable before and still had problems. At this moment my macbook loads again, but I don't know if its because of the board or again just luck. Thank you very much for the guide.
