1. Remove the memory module cover.
2. Ground yourself by touching the unpainted metal surface of an I/O 
connector on the computer’s back panel.
3. To release the memory module from its socket, carefully spread apart          
the inner tabs of the memory module socket just far enough for the 
memory module to disengage from the socket (it should pop up slightly)                
(see Figure 7).
4. Lift the memory module out of its socket.
To replace a memory module, perform the following steps:
1. Align the memory module’s edge connector with the slot in the center of 
the memory module socket. 
Memory modules are keyed, or designed to fit into their sockets in only 
one direction. The slots on the system board are notched so that the 
memory module can be firmly seated only one way.
2. With the module at a 45-degree angle, press the memory module’s edge 
connector firmly into the memory module socket.
3. Pivot the memory module down until it clicks into place.
4. If you do not hear a click as each end of the memory module snaps into the 
tabs, remove the memory module and reinstall it.

5. Remove the two M2.6 x 6-mm hinge screws that secure the left hinge to 
the bottom case.
6. Carefully disconnect the display-assembly interface wire connector, 
located on the left side of the display assembly, from the system board.
The female connector attached to the display-assembly interface wire is

remove the wire from under the hinge, remove all three M2 X 4-mm 
screws attaching the left hinge to the display-assembly top cover (see Fig-
ure 11). For models that do not route the interface wire under the left 
hinge, the wire is removed without removing the left hinge.
7. Carefully disconnect the display-assembly inverter wire connector, located 
on the right side of the display assembly, from the system board.
The female connector attached to the display-assembly inverter wire is 
keyed to fit into the male connector one way only.
