Additional Steps
Reassembly Notes: The notched end of the metal
tube fits under the display bracket, and the tab on the
side fits inside the hinge opening.
The upper grounding tab of the cable attaches around
the hole for the left bezel screw in the display bracket.
Secure the LCD flex cable to the display bracket with a
piece of conductive tape near the hinge.
Secure the LCD flex cable to the LCD module with a
piece of Kapton tape next to the LCD connector.
Caution: Use compatible parts (page 2-11).
Reassembly Notes: The cable should protrude about
6 cm from the hinge. Secure the LCD flex cable to the
display bracket with a piece of Kapton tape near the
hinge.
Secure the LCD flex cable to the LCD module with a
piece of Kapton tape next to the LCD connector.
Caution: Use compatible parts (page 2-11).
Remove the motherboard only far enough to slip the
cover off the audio jacks.
Remove two screws from CPU module. Unplug CPU
module from motherboard.
Caution: Install both parts of a CPU thermal kit to the
new CPU. Stick the pad to the top of the CPU. Stick
the rubber spacer to the top back-right corner of the
board.
Reassembly Notes: Spread a thin layer of thermal
grease on the heatsink before installing the fan.
Place the vent in the side of the fan toward the side of
the heatsink.
Make sure the fan cable is positioned so it does not
interfere with contact points on the underside of the
heatsink.
Reassembly Notes: Install the hinge so the slit in the
housing faces into the display case.
Caution: If the display is attached to the bottom case,
install one new hinge before you remove the other to
avoid stressing the cables.
Caution: Use compatible parts (page 2-11).
