Removing the Computer Cover
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
Rotate the cover release knob in a clockwise direction, as shown in the illustration.
Slide the computer cover forward by 1 cm (½ inch), or until it stops, and then raise the cover.
CAUTION: Graphics card heat sinks can become very hot during normal operation. Ensure that a graphics card heat sink has had sufficient time to cool before you touch it.

Chassis Intrusion Switch
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTE: The chassis intrusion switch is standard on the ultra small form factor computer but is optional on mini tower, desktop and small form factor computers; it may not be present on your computer.
Disconnect the chassis intrusion switch cable from the system board by using two fingers to squeeze
the release mechanism on one side of the connector as you pull to disconnect the cable connector.
Slide the chassis intrusion switch out of its slot in the metal bracket, and then push it down through
the square hole in the bracket to remove the switch and its attached cable from the computer.
NOTE: You may feel a slight resistance as you slide the switch out of the slot.
Replacing the Chassis Intrusion Switch
Gently insert the switch from underneath the metal bracket into the square hole in the bracket, and
then slide the chassis intrusion switch into its slot until you feel it snap securely into place.
If you are using a computer stand, attach it to the computer.
Resetting the Chassis Intrusion Detector
Turn on (or restart) your computer.
When the blue DELL™ logo appears, press <F2> immediately.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop. Then shut down your computer and try again.
Select the Chassis Intrusion option and then press the left- or right-arrow key to select Reset. Change
the setting to On, On-Silent, or Disabled.
NOTE: The default setting is On-Silent.
Save your BIOS settings and exit system setup.

If your AC power cable has a green ground wire for connection to an
electrical outlet, connect the metal ground connector to the grounding
source (often a screw) on the outlet (see the following illustration):
Loosen the grounding source.
Slide the metal ground connector behind the grounding source, and
then tighten the grounding source.
