System Board Removing the System Board CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover. CAUTION: The heat sink assembly, power supply, and other components may be very hot during normal operation. Be sure that they have had sufficient time to cool before you touch them. NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components. 1 Follow the procedures in "Before You Begin" on page 101. 2 Remove the computer cover (see "Removing the Computer Cover" on page 103). 3 Remove any add-in cards on the system board (see "Cards" on page 115). 4 Remove the processor and heat sink assembly (see "Removing the Processor Fan/Heat Sink Assembly" on page 156). 5 Remove the memory modules (see "Removing Memory" on page 115) and document which memory module is removed from each memory socket so that the memory modules can be installed in the same location after the board is replaced. 6 Disconnect all cables from the system board. Note the routing of all cables as you remove them so that you can re-route them correctly after installing the new system board. 7 Remove the eight screws from the system board. 8 Lift the system board up and out. 164 Removing and Installing Parts
