A/2 LS PRO OWNER'S HANDBOOK
Inside the System Unit
Appendix A
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.
When installing any upgrade, be sure you understand what the
installation procedure involves before you start. This will enable
you to plan your work, and so minimize the amount of time
that sensitive components are exposed.
Do not remove the system unit cover, nor the anti-static bag
or wrapping of any upgrade, until you need to.
Handle static-sensitive items with extreme care. Hold expansion
cards and add-on components only by their edges, avoiding their
electrical contacts. Never touch the components or electrical
contacts on the motherboard or on expansion cards. In general,
do not handle static-sensitive items unnecessarily.
Keep all conductive material, and food and drink, away from
your work area and the open computer.
Opening the system unit
To remove the system unit cover:
1. Turn off both the system unit and the monitor.
2. If your AC power outlets have switches, set them to
their Off positions.
3. Unplug all power cords from rear of the system unit.
4. Remove the two screws that secure the top cover.
5. Grasp the handle beneath the security loop and tug it
rearwards slightly to loosen the top cover, then lift
the top cover off.
