Duration: 45 minutes

Steps: 27 Steps

Hey there, tech whiz! Just a heads-up, make sure you’re handling your device with care during this repair. Keep those tools steady and your workspace tidy. Let’s ace this fix together!

This nifty cable is the secret handshake between the left I/O board and the logic board. Let’s get them talking!

Step 1

– Pop the battery out by nudging the release tabs with your fingers. Lift that battery away like you’re lifting the lid off a treasure chest!

Step 2

– Unscrew the trio of matching Phillips screws from the memory compartment door. Let’s get this party started!

Step 3

– Gently hoist the memory door just enough to get a good grip, then whoosh it toward you and away from the body of the device. It’s like magic, but you’re the wizard!

Step 4

– Unscrew the two 2.8 mm Phillips party poopers hiding in the battery compartment near the latch.

Step 5

– Alright, gear up to unscrew the following 6 screws:

Step 6

– Unscrew the four 3.2 mm Phillips screws chilling on the port side of your device. Let’s keep it loose and breezy, you got this!

Step 7

– Twist your computer 90 degrees and unscrew the two 3.2 mm Phillips screws located at the back. Keep going, you’re doing great!

Step 8

– Give your computer a little twirl and spin it 90 degrees again. Now, take out those four 3.2 mm Phillips screws from the side like a pro.

Step 9

Take it slow, champ! Don’t just rip off the upper case like you’re opening a bag of chips. Remember, it’s still connected to the logic board by a delicate ribbon cable.

– Start by lifting the rear end of the case and wiggle your fingers along the sides to loosen it. As you make progress, gently rock the case up and down to detach the front part. This will help unclick some sneaky plastic clips holding it together.

Step 10

– Unplug the trackpad and keyboard ribbon cable from the logic board. Peel off any tape that’s in your way.

– Time to part ways with the upper case—lift it off gently.

Step 11

– Slide the iSight cable to the left and gently wiggle it out of its connector on the logic board. Easy peasy!

Step 12

– Pop those cables off like a pro! Use a spudger to gently lift the inverter, left fan, and left ambient light sensor cables. Just slide it underneath each cable and give it a little nudge upwards. You got this!

Step 15

– Hoist the left fan up and while you’re at it, gently peel the tape that’s hugging the fan to the heat sink. Keep it cool and steady!

Step 16

– Unplug the hard drive and ExpressCard connectors from the left side of the logic board. You’re doing great!

Step 17

– Unplug the three antenna cables from the Airport Extreme card.

– Apple made it super easy with a handy label showing where each colored antenna cable goes. Don’t forget to check this when you’re hooking them back up!
