Removing the Microprocessor Thermal-Cooling Assembly
CAUTION: Before performing the following procedures, read the safety instructions in your Product Information Guide.
NOTICE: To prevent damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface.
NOTICE: Disconnect the computer and any attached devices from electrical outlets, and remove any installed batteries.
Remove the captive screw that attaches the display cable to the system board.
Disconnect the display cable from the display cable connector on the system board.
Release the display cable from its routing clips and slide it out from beneath the tab on the
palm rest.
Release the two antenna cables from the two antenna-securing clips.
Disconnect one antenna cable from the display by holding the two gold antenna connectors
and gently pulling them apart. Then disconnect the other antenna cable. (The gold antenna
connectors on each cable are keyed to ensure that they are correctly reconnected.)
