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.
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.
