Security Cable Lock

Passwords

Computer Tracking Software

If Your Computer Is Lost or Stolen

NOTE: For information on how to secure your computer while traveling, see Traveling With 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

NOTE: Passwords are disabled when you receive your computer.

A primary password, an administrator password, and a hard drive password all prevent unauthorized access to your computer in different ways. The following table identifies types and features of passwords available on your computer.

Type of Password Features

•Protects the computer from unauthorized access

Primary/System

 

• Gives system administrators or service technicians access to computers for repair or reconfiguration

Administrator

• Allows you to restrict access to system setup in the same way a primary password restricts access to the computer

•

Can be used instead of the primary password

 

 

 

Hard drive

• Helps protect the data on your hard drive or external hard drive (if one is being used) from unauthorized access

 

 

NOTE: Some hard drives do not support hard drive passwords.

NOTICE: Passwords provide a high level of security for data in your computer or hard drive. However, they are not foolproof. If you require more security, obtain and use additional forms of protection, such as smart cards, data encryption programs, or PC Cards with encryption features.

If you forget any of your passwords, contact your system administrator or contact Dell (see Contacting Dell). For your protection, Dell support staff will ask you for proof of your identity to ensure that only an authorized person can use the computer.

Using a Primary/System Password

The primary (system) password allows you to protect the computer from unauthorized access.

Access User Accounts from the Control Panel to create user accounts and add or change passwords. After assigning a primary password, you must enter it each time you turn on your computer.

If you do not enter a password within 2 minutes, the computer returns to its previous operating state.
