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 Penryn 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

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, also serving as a northbridge.
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.
Can you label the connectors as to what they go to? Where I work we have to disable the iSight and in some cases the wireless interfaces.
Some of these:
CY8C24794-24L is a SoC with a lot of bus interfaces, a LOT of analog interfaces and CapSense touch capabilities. This chip is very versatile and function cannot be determined by it's typenumber. It might run fanspeed, touchpad, backlight, temp. sensors and lot of other functions I cannot even think up at the moment.
RTL8251CA is the 10M/100M/1G bit ethernet chip.
H5RS5223CFA are the GDDR3 videomemory chips.
ISL6236 is the power supply controller.
There are also two small hinge parts on top of these six screws that need to be taken off. Big step missing here. Disassembling the hinges and separating the display from lower case is complicated procedure that needs more pictures/directions.
