MacBook Pro 15インチ Retina Display Early 2013のMagSafe DC-Inボードの交換

Thank you for this guide, my room flooded and my laptop got wet. the entire display had a water bubble, but i kept it under 2 fans for a month, and the water dried out except for a little spot at the bottom of the screen. But, my computer stopped charging, and i didnt see any lights on the charger turning on. the laptop worked as long as connected to power, but wasn’t charging my battery. When my battery power eventually hit zero, my laptop wouldn’t switch on anymore. Took it to an apple store, they quoted me a price of $1350, when a new laptop starts at $1200. I found out the problem was the magsafe port, ordered the part and the screwdrivers needed, followed this guide, and in about 3 - 3.5 hours and parts cost under $50, my laptop is working properly again with no problems. For a first timer, the whole process looks daunting, but it was kind of fun and not at all as problematic as I thought it would be. Thanks again.

OMG! It is entirely possible to both remove and replace the MagSafe Connector without removing the logic board, making this 5 or 6 steps instead of 33!!

Once you remove the lower case (and disconnect the battery if you feel you must—I’ve been inside my MacBook a dozen times and no longer find that necessary, although it probably is safer to disconnect it), you can skip skip straight to Step 28 and remove the display data cable. Move that out of way and remove the two screws securing the MagSafe Connector.

Now, with a little finesse you can lift the MagSafe board and slide its connector out of the logic board. I nudged it out a bit with a screwdriver from the part that was visible (on the other side of the logic board) and gently pulled the five wires and it slid right out. It didn’t put any stress on the wires at all.

To give myself some wiggle room I also removed:

one screw from step 30 (5.2 mm Raised Head T5 Torx screw)

two screws from step 16 (4.4 mm T5 Torx screw and 5.0 mm T5 Torx screw with 2 mm collar)

I’ve read this all through and at first it looked daunting, but the above comment which reduced it to many fewer steps got me interested. What is the most difficult part (I really don’t want to damage anything, rip off delicate connections etc.)

I’m hoping my magsafe connector is fried, as not expensive to replace. What visible evidence is there showing it has failed? Does it have to show signs of burning, or can it fail with no obvious damage?

Charger was getting very hot and no LEDs lighting up.

I replaced the power adapter and cleaned all magsafe contacts, the outer two were black (the ground terminals?) but plastic surround not melted. Laptop works fine with charger connected, but only shows 2% charge which never changes. If I take out connector, laptop closes down quickly. I hope the logic board is OK……

thx . useful info

This is the first time I opened my MacBook Pro. Thanks for your procedure. The keyboard ribbon from the Step 24 is so thin. It is like thinner than X-ray film. I was afraid to remove the ribbon from the socket. So, I skipped this step and follow other steps till ‘Step 30’. I didn't remove the logic board as shown in Step 31 and 32. Instead, I removed DC board screws and then DC board from the hole. The cable from the DC board connected at bottom corner of the logic board. I hold the MacBook Pro vertically and lift the logic board slightly and removed the DC board ‘plug’ from the socket. Next, I plugged in the new DC board and followed this procedure in reverse order ( from Step 30 to Step 1). Everything went fine.

Important Note: When lifting logic board, please do it carefully and very slowly. Don’t be hurry and don’t break anything. Use magnifying glass or Magnifier in your iPhone to see the tiny parts big and clearly, before removing them.
