Chassis Intrusion
An integrated chassis intrusion alarm displays the status of the system chassis intrusion monitor. If the chassis has been opened, the setting
changes to Detected and the following message appears during the boot sequence at system start-up:
Alert! Cover was previously removed.
Use System Setup to reset the alarm so that future intrusions are detected.
Security Cable Slot and Padlock Ring
On the back of the computer are a security cable slot and padlock ring (see Figure 3 ) for attaching commercially available antitheft devices.
Security cables for personal computers usually include a segment of galvanized cable with an attached locking device and key. To prevent
unauthorized removal of your computer, loop the cable around an immovable object, insert the locking device into the security cable slot on the
back of your computer, and lock the device with the key provided. Complete instructions for installing this kind of antitheft device are usually
included with the device.

Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. However, they are not foolproof. If
your data requires more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption
programs.
NOTE: Antitheft devices are of differing designs. Before purchasing such a device, make sure it works with the cable slot on your
computer.
