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 the 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.
The 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. This
means that working surfaces, floor coverings and chairs must be
connected to a common earth reference point, and you should wear
an earthed wrist strap and anti-static clothing. It is also a good idea
to use an ionizer or humidifier to remove static from the air.
