NOTE: This system uses two types of chassis. One chassis uses a cover with
a built-in support beam. In the other chassis, the support beam is attached to
the chassis and must be removed to access internal components.
To remove the computer cover and support beam from a desktop or mini
tower system, follow these steps:
1.
Observe the “Warning for Your Personal Safety and Protection of Your Equip-
ment” found earlier in this chapter. Also, observe the safety instructions at
the front of this guide.
2. If you are working on a mini tower system, lay the computer on its right
side with the chassis foot off the edge of the work surface to allow the
computer to lay flat.
