Removing the Cover and Support Beam: Dell™ Dimension™ XPS Rxxx Systems

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. 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.
2. Loosen the cover-mounting thumbscrew that secures the cover to the back of the computer.

NOTE: The thumbscrew is captive and stays in the cover when loosened.

WARNING: To prevent cuts, keep your hands clear of the metal edges on the chassis and fan guard as you slide back the cover.

3. Face the front of the chassis. Use your thumbs to press in both cover release latches while pushing the cover backward. Move the cover back about an inch, and then lift it straight up off the chassis.
   If necessary, use both hands and work one side at a time.
4. If your chassis has a support beam attached to it, pull up the front end of the beam until it snaps free from its fastener. Lift the front of the beam until the hinged tabs on the back end of the beam clear their slots.

Replace the computer cover and support beam on a desktop or mini tower chassis as follows:

1. If you removed the support beam from the chassis, slip the beam’s hinged tabs into their slots and lower the beam. Then place the lock tab into its fastener, and press down on the front end of the beam until it snaps into position.
2. Position the cover on the chassis approximately one inch back. Slide the cover forward until it locks into place.
3. Tighten the cover-mounting thumbscrew on the back of the chassis.
