Padlock Ring and Security Cable Slot
Use one of the following methods to secure your computer:
l Use a padlock alone or a padlock and looped security cable with the padlock ring.
A padlock alone prevents the computer from being opened.
A security cable looped around a stationary object is used in conjunction with a padlock to prevent unauthorized movement of the computer.
l Attach a commercially available antitheft device to the security cable slot on the back of the computer.
Antitheft devices usually include a segment of metal-stranded cable with an attached locking device and key. The documentation that comes with the
device contains instructions for installing it.
Password Protection
System Password
NOTE: When the administrator password is enabled, you must know the administrator password before you can reset the Chassis Intrusion setting.
NOTE: Before you purchase an antitheft device, make sure that it works with the security cable slot on your computer.
NOTICE: Although passwords provide security for the data on your computer, 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.
