Introdução

We disassembled this computer on October 15, 2008.

This teardown is not a repair guide. To repair your MacBook Unibody Model A1278, use our service manual.

Apple boasts that, "The new MacBook packaging is 41 percent smaller than the previous generation" and is made from recycled material.

  • Smaller packaging, they say, means fewer planes to transport the same number of products.

It looks like a MacBook Air from the top, but it's about 25% thicker than the thickest part of the Air, and almost 6 times thicker than the thinnest part.
  • It looks like a MacBook Air from the top, but it's about 25% thicker than the thickest part of the Air, and almost 6 times thicker than the thinnest part.

  • To be fair, though, it's about 12 percent thinner than its predecessor (0.95 in vs. 1.08 in) and 10 percent lighter (4.5 pounds vs. 5 pounds).

  • In the box:

    • 85-page user's manual

    • Restore DVDs

    • 60-watt AC adapter

    • AC adapter extension cable

    • Cleaning cloth

  • As with previous MacBooks, there's no video adapter included. There's an empty spot in the box where it would fit nicely, but there's no adapter to be found. Apple offers the DisplayPort adapter for $29 extra.

Adicionar comentário

  • There's a new Mini DisplayPort (fourth from the right), and a complete lack of a FireWire port.

  • It may be hard to tell from the image, but there are now 8 lights on the battery indicator, and it's conveniently located where you can actually see it.

Adicionar comentário

  • Opening the battery latch.

  • For those hurt by the financial crisis, a coin is no longer required.

Adicionar comentário

  • The hard drive is on the left, and the battery is on the right.

  • The new MacBook uses the same hard drives as previous MacBook models.

  • Shameless plug: If you're not ready for a new machine, you can upgrade the hard drive in any Apple laptop. We have free guides for most models that make hard drive replacements easy.

Beautiful computer . Even in 2017

  • The battery is 45 watt-hours compared to 55 on the previous generation. It's also almost 20 percent lighter (302 g vs. 402 g).

  • Still, Apple claims that you'll get 5 hours of wireless productivity (with the display brightness set to 50 percent).

Adicionar comentário

  • The hard drive is held down by a single Phillips screw.

  • Like the last black MacBook, the standard hard drive on the 2.4 GHz model is 250GB SATA and 5400 rpm.

Adicionar comentário

  • Disconnecting the hard drive.

  • To replace the hard drive, you'll need a T6 Torx screwdriver to transfer the hard drive mounting screws to the new drive.

Adicionar comentário

  • The bottom panel is attached by 8 screws:

    • One 3 mm Phillips in the top left corner.

    • Four 3.5 mm Phillips along the bottom.

    • Three 13.8 mm Phillips along the top.

what type of screws are those, i'm missing those threws

step 10

  • Removing the bottom panel provides access to the RAM, optical drive, display hinge, fan, and logic board.

  • It looks like the only really hard part to replace will be the upper case and keyboard.

Adicionar comentário

  • Removing the RAM

  • 2GB (two 1GB SO-DIMMs) of 1066MHz DDR3 SDRAM are included. Apple will upgrade the RAM to 4GB for an extra $150.

  • Apple claims this machine maxes out at 4GB RAM, but the Montevina chipset appears to support up to 8GB.

  • Shameless plug: You can upgrade your existing MacBook or MacBook Pro to 4 GB. We'll also be offering the RAM for the new Unibody machines in the near future.

It's been tested... 6GB max. Why? Who knows, but the computer will not recognize 8GB (and a 4GB chip for this machine is still stupid expensive...)

fairleymac - Responder

Nope, not true. I am currently running 8 GB (2 x 4GB Corsair) in my Late 2008 Unibody MacBook.

Given, it was probably adjusted in some later update in the 5 years since you posted that comment. Still, useful to know.

Kevin K - Responder

Yes Kevin it id useful for me I have late 2009 Macbook Uni.

Ice - Responder

  • We've now exhausted the installation instructions Apple printed on the back of the battery cover.

  • Disconnecting the subwoofer and optical drive cables.

I am having a hard time disconnecting the subwoofer cable from the logic board. Does it pop straight off? Is there a trick?

pjohn07 - Responder

Be very careful here. Mine had a small piece of foam on too. Peal this off carefully. Don't peel from the corner of the plastic square. Slide wire side gently away toward optical drive. If possible hold down very thin sides of retaining clip while pulling away.

  • The optical drive is held in by the following 4 screws:

    • Three 2.5 mm Phillips.

    • One 3.7 mm Phillips.

  • Apple gives the following specification: 8x SuperDrive (DVD±R DL/DVD±RW/CD-RW).

Adicionar comentário

  • The optical drive, now SATA.

  • The optical drive shows a manufacture date of October 2008. That drive sure got from the factory to us fast!

Adicionar comentário

  • Removing the logic board.

  • This may be the most beautiful laptop we've disassembled. Apple has a right to be proud of their engineers and manufacturing team.

I'd love some more detail on which screws need to be removed in order to remove the logic board.

This is a teardown, and should not be used as a repair guide due to many missing steps. The repair guides for this machine can be found here.

If you were to double or triple the resolution of the huge image, then we could read the part numbers and perhaps help in mapping out the circuit

Tom Dowad - Responder

are there different types of logic boards that I can replace mine with? and where can i get them

matt - Responder

  • The bottom of the logic board.

  • Part numbers found thus far:

SN802043 is the actual part number (The numbers 87K JR7C G4 are different on each IC batch produced). This part is hard to get (unless you live in USA) and is not listed in Texas Instruments website http://www.ti.com If anybody in UK has this part, please Add a comment.

  • Removing the right speaker and subwoofer.

  • The new MacBook received a welcome speaker upgrade. In the second image, the old plastic MacBook's speakers are on the left, and the new MacBook's speakers are on the right.

Adicionar comentário

  • The elegant new glass and Aluminum display assembly.

  • Amazingly, the new display assembly weighs slightly less than the previous MacBook's plastic display assembly.

could this be replaced with a newer macbook air 13.3inch screen thereby increasing this macbooks resolution?

Calum Macrae - Responder

  • All major components - only 4.5 pounds, not bad for a full-featured, metal laptop.

  • Looking for more pictures? We've also disassembled the new MacBook Pro.

My comp turns on and the screen turns white and stays white. If I hook it up via hdmi it works fine through my tv. Need help on what it could be

Joey c - Responder

Apple will help you. Simply ask them (Customer Service) for a reply.

Ethan Zuo -

While disassembling my MacBook 2008-11 model as seen in these pictures, I was careful to lay out and label each part to reassemble after attempting to repair from water damage. When I lifted the hard drive a small black rectangular bracket about 1/2 wide with a small square on the back and an extruding piece against the black hollow square tha appears would go over a screw hole; dropped to the floor. It has part number ZYI-4 as best I can make out. Does anyone know where this goes? I cannot figure it out. Thanks!!!!
