Edit Step 1 Logic Board  ¶ 

  • Use the flat end of a spudger to lift the right fan connector out of its socket on the logic board.

  • It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.

Edit Step 2  ¶ 

  • Remove the three 3.4 mm (3.1 mm) T6 Torx screws securing the right fan to the logic board.

  • Lift the right fan out of its opening in the logic board.

Edit Step 3  ¶ 

  • Pull the camera cable out of its socket on the logic board.

  • Don't lift upward on the camera cable as you disconnect it. Pulling upward on the cable may damage both the cable and the logic board. Pull the cable parallel to the face of the logic board.

Edit Step 10  ¶ 

  • Use your fingernail to flip up the retaining flap on the keyboard ribbon cable ZIF socket.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

  • Use the tip of a spudger to pull the keyboard ribbon cable out of its socket.

Edit Step 12  ¶ 

  • Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-In side of the computer.

  • Pull the display data cable straight out of its socket on the logic board.

  • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

Edit Step 13  ¶ 

  • Use the tip of a spudger to flip up the retaining flap on the keyboard backlight ribbon cable ZIF socket.

  • Be sure you are flipping up the hinged retaining flap, not the socket itself.

Edit Step 14  ¶ 

  • Remove the following nine screws:

    • Seven 3.4 mm ( 3.1 mm) T6 Torx screws on the logic board

    • Two 8 mm T6 Torx screws on the DC-In board

Edit Step 15  ¶ 

  • Carefully lift the logic board assembly from its left side and work it out of the upper case, minding the optical drive cable and the I/O ports that may get caught during removal.

  • If necessary, use the flat end of a spudger to separate the microphone from the upper case.

  • Pull the I/O port side of the logic board away from the side of the upper case and remove the logic board assembly.

To reassemble your device, follow these instructions in reverse order.

Of course, this is not the right fan but the left in the picture.

Need a better picture of the zif connector. You lift the lock from the side farthest from the flat cable, and it lifts toward the cable. When reinserting be sure to get the cable all the way or you may have only half the keyboard working.

I could use some advice on reinserting the ZIF cable firmly in its socket. I can get it started, but getting it far enough in to make contact is difficult, given its flexibility. Any tips on manipulating it?

I used a piece of sticky tape that I attached to the ZIF cable, then pulled firmly on the tape (attached to the cable) to get the ZIF cable to seat properly. The tape held to the cable, the ZIF cable seated properly, and the keyboard worked.

robertemcgee,

The metallic flap controlled by the plastic handle looks like it could easily break... a safer route is to grab the shielded cable after rotating the metal flap out of socket and gently pry it out of the socket by applying force parallel to the logic board. It will probably take a few minutes but you could save yourself some gray hairs.

This is the hardest step IMO

Indeed this s the hardest step.its not clear from the instruction that there are two elements to this component. The connector and also a metal retaining clip that needs to be rotated off the connector first.

I had a little difficulty pulling the motherboard before the battery. I'm not sure why you would want to do it in the order listed here, but doing steps 23 and 24 first helped the board come out easier.
