Removing the System Board
CAUTION:
To guard against electrical shock, laceration by moving fan blades, or
other unexpected injuries, 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 "Removing a PCI/PCI
Express Card" on page 121).
4 Remove the processor and the heat sink assembly (see "Removing the
Processor" on page 148).
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.
