Securing Your Computer
Security Cable Lock
NOTE:
Your computer does not ship with a security cable lock.
A security cable lock is a commercially available antitheft device. To use the lock, attach it to the
security cable slot on your Dell™ computer. For more information, see the instructions included
with the device.
NOTICE:
Before you buy an antitheft device, ensure that it will work with the security cable slot on your
computer.
Passwords
Passwords prevent unauthorized access to your computer. When you first start your computer, you
must assign a primary password at the prompt. If you do not enter a password within 2 minutes, the
computer returns to its previous operating state.
When using passwords, observe the following guidelines:
• Choose a password that you can remember, but not one that is easy to guess. For example, do not
use the names of family members or pets for passwords.
• It is recommended that you do not write down your password. If you do write it down, however,
ensure that the password is stored in a secure place.
