Padlock Ring and Security Cable Slot
Use one of the following methods to secure your computer:
Use a padlock alone or a padlock and looped security cable with the padlock ring. (For the location of the padlock on
the Dell Precision 670 computer, see " Inside Your Computer " and for the Dell Precision 470 computer, see " Inside Your
Computer .") 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.
Attach a commercially available antitheft device to the security cable slot on the back of the computer.
NOTE: Before you purchase an antitheft device, make sure that it works with the security cable slot on your 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
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.
System Password
NOTICE: If you leave your computer running and unattended without having a system password assigned, or if you
leave your computer unlocked so that someone can disable the password by changing a jumper setting, anyone can
access the data stored on your hard drive.
Option Settings
You cannot change or enter a new system password if the following option is displayed:
Disabled — The system password is disabled by a jumper setting on the system board.
