A INSIDE THE SYSTEM UNIT
This appendix provides step-by-step instructions on obtaining
access to the inside of the system unit for the purposes of
maintaining or upgrading the system. Details of all relevant
motherboard jumper settings are included.
Warning
Turn off the computer and unplug all power cords before removing
the top cover.
Anti-static precautions
Static electricity can cause permanent damage to electronic
components. You should be aware of this risk, and take
precautions against the discharge of static electricity into your
computer.
Anyone can generate static electricity by moving on a chair,
brushing against desks or walls, or simply walking across an
ordinary carpet. Items handed from one person to another, or
being wrapped or unwrapped, can acquire a static charge. Air
conditioning systems can also result in ambient static. Clothing
made of synthetic fibres is particularly likely to generate static
electricity; this static electricity is often completely unnoticed
by the wearer, but can be sufficient to cripple or impair an
electronic component.
Your computer is at risk from static discharge while the top
cover is off. This is because the electronic components of the
motherboard are exposed. Memory modules, cache upgrades
and OverDrive processors are other examples of electrostatic
sensitive devices (ESSDs).
All work that involves removing the cover must be done in an
area completely free of static electricity. We recommend using
a Special Handling Area (SHA) as defined by EN 100015-1: 1992.
