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.
