MacBook Pro Unibody First Look

Step 1 — First Look

• The new, 37 percent friendlier-to-squirrels and tree-frogs MacBook Pro box. Yay for pallet density! Oh, and it’s heavier than it looks.
• Follow our updates on twitter: ifixitlive

Step 2

• Old on the left, new on the right.
• The keyboard is now more similar to the old MacBook than the previous MacBook Pro. While the unibody case is very cool, this is going to make keyboard repair difficult.
• That screen isn’t just glossy, it’s a mirror!

Step 3

• New, rounded bottom. And a much darker plastic wireless window.
• In the box:
  • 85 page manual (same length as MacBook manual– that’s some coordination!)
  • Cleaning cloth and two Apple stickers
  • 85W power adapter
  • Application DVD with iLife. Interestingly, this DVD refused to run on our older Leopard MacBook Pro.
  • OS X 10.5.5 restore DVD.

Step 4

• The holes in the speaker grill are significantly smaller, making the upper case surface feel smoother.

Step 5

• Ports, left to right:
  • Magsafe, Gigabit ethernet, Firewire 800, Two USB 2.0, “Industry-standard” DisplayPort, Audio-in, Audio-out
  • ExpressCard/34 slot, same as before.
  • Both audio in and out are hybrid digital / analog line minijacks. Very cool!
• Is the lack of Firewire 400 the beginning of the end for Firewire?

Step 6

• Removing the battery cover.
• Aww, look at the cute little Apple logo.

Step 7

• Remove the four T6 screws securing the hard drive.
• Replacing the hard drive is significantly easier on this machine than the previous MacBook Pro.
• This machine uses the same, industry standard SATA notebook drives as previous MacBook Pro and MacBook models.
• Shameless plug: Of course, you can upgrade the hard drive in any Apple laptop. We have free guides for every model that makes hard drive replacement easy.
• Kudos to Apple for making this easy. Keeping repair costs down is probably the most environmentally friendly thing Apple has done with this machine.

Step 8

• The first step to opening this machine is removing the bottom plate.
• Remove the following 8 screws:
  • Four 3.5 mm Phillips.
  • One 5.3 mm Phillips.
  • Three 13.8 mm Phillips.
• Let’s see what’s creating all that torsional rigidity that Jony Ive keeps talking about.

Step 9

• We’re inside!
• Disassembling this laptop is reminiscent of the old PowerBook G4 Titanium models, and very similar to the MacBook Air.
• You remove the bottom plate, and everything is screwed into the upper case. The case is now Apple’s custom-machined unibody enclosure.
• The interior is cleaner and flows together better than the previous Pro.
• Cable routing from various parts of the case to the logic board is simpler in this than the new MacBook because Apple had more room to play with.

Step 10

• Removing the two 1 GB DIMMs.
• Apple is sticking with 32-bit chipsets for their portables, so you’ll be stuck at 4GB RAM forever with this machine.
• Shameless plug: You can upgrade your existing MacBook or MacBook Pro to 4GB as well.

Step 11

• We’re going to remove the optical drive next.
• Disconnect these two connectors.

Step 12

• To free the Superdrive, remove the following 3 screws
  • Two 2.8 mm Phillips screws.
  • One 3.5 mm Phillips screws.

Step 13

• Liberating the optical drive from the confines of this beautiful machine.

Step 14

• The optical drive is SATA for the first time. Panasonic model #UJ878A.
• The superdrive in the last model was ATA, model #UJ857.
• You can see the different connectors in the middle picture. The new, SATA connector is on top.
• The rightmost photo is a shot of the new drive label.

Step 15

• Disconnect two connectors, one at the bottom right of each fan.
• Remove the following 6 screws:
  • Three 3.1 mm Philips screws.
  • Three 3.7 mm Philips screws.

Step 16

• Removing the two cooling fans.
• Apple has long used a unique fan design with a high number of fan blades. This allows them to achieve moderate airflow with low RPM. The slower the fan spins, the quieter it is.

Step 17

• There are a number of ribbon cables to disconnect from the logic board.

Step 18

• Remove the following 11 screws:
  • Seven 3 mm Phillips.
  • Two 4 mm Phillips.
  • Two 7 mm Phillips.
• While our circles make it look like there are a lot of screws, this machine appears to have fewer screws than the previous MacBook Pro. These screws all attach directly to the solid-piece upper case, which should simplify maintenance a bit.

Step 19

• Removing the logic board.
• We’re noticing a lot of hardware similarities between the MacBook Air, new Macbook, and this MacBook Pro.
• Apple has taken their new manufacturing approach to heart, and is using the flexibility it provides to standardize as much of their design as possible.

Step 20

• The top of the logic board, with the heatsink still attached.

Step 21

• Logic board top with heatsink removed.
• The large chip on top is the Intel 2.4 GHz Montevina processor. It has 3M L2 cache and a 1066 MHz bus. Markings: 5827B493 SLB4N AV80577P8600
• The other two large chips are Nvidia graphics chips.
• We’ll post part numbers as we identify them.
  • TDK 6T213HF 0836 e
  • LSI L-FW643-6 13859176

Step 22

• Logic board bottom.
• Part numbers:
  • H5RS5223CFA 11C 834A; LFXPW-AE 5MGC A827RR83; ISL6236 IRZ H832BL4; F2117LP 20H V AF00391 0823JPN; ISL9504 BHRZ H0832BBX2; CY8C24794-24L FXI 0831 A 05 KOR CYP 633912; REALTEK RTL8251CA 85983Q1 G824; ISL6236 IRZ H832BL4; NXP L0614 01 21 ZPD824
• We’d love help identifying parts and chips. If you have any information, let us know: kyle (at) ifixit dot com.

Step 23

• Here are the two Nvidia chips! They occupy a significant amount of the logic board. There’s no way both of these puppies could fit in a MacBook Air.
• The first chip is marked 37N3C2 0836B2 PB6623.S03 MCP79MXT-B2. This is the GeForce 9400M, which only runs 16 processor cores and 54 Gigaflops.
• The second, larger chip is marked U807B034 0827C1 NH7962.01W G96-632-C1. This is the GeForce 9600M GT, which has 32 processor cores and is capable of 120 Gigaflops.

Step 24

• Continuing the disassembly, we’re going to remove the display assembly.
• Remove six 6 mm T-6 Torx screws near the hinge.

Step 25

• Removing the lower display bezel.

Step 26

• Removing the Airport card.
• Disconnect the antenna connector and the data cable.
• Remove the two screws.
• The Bluetooth cable disappears into the display, and our sources tell us that it’s sandwiched between the glass and the metal case. This means that if your Bluetooth goes out, you may have to replace the entire display!

Step 27

• Airport card (the pink is a thermal pad).

Step 28

• The “unibody” upper case assembly.
• This case assembly includes the keyboard, glass trackpad, and ribbon cables.
• While the manufacturing of the case is sexy, our sources say that Apple is treating this as a single replaceable part. This means that if you break a key on the keyboard, you’ll have to replace the entire upper case. That could get very expensive.

Step 29

• In an attempt to save a lot of people a lot of money, we’re going to try removing the keyboard from the upper case.

Step 30

• The keyboard is secured by lots of tiny black Phillips #000 screws. We’re removing ALL of them.

Step 31

• OK, we got them all out. There are 56 screws on the keyboard, plus two on the power button.
• This is looking promising!

Step 32

• We got it off! Phew. It took about 15 minutes to remove all the screws.
• It looks like users will be able to repair their own keyboards after all! Great news for the heavy-handed and spill-prone.
• We plan on having these in stock.

Step 33

• Wow! What an incredible machine. We are very impressed by the ease with which the new MacBook Pro came apart. This machine should be a joy to work on.
• Bottom left: hard drive and battery.
• Top: Display
• Center: Logic board, fans, and sepakers
• Bottom-center: subwoofer, optical drive, RAM, and heatsinks.
• Right: Custom-machined unibody upper case and keyboard.
• Here’s a high resolution image.
• Looking for more pictures? We’ve also disassembled the new MacBook.
