Dell Precision 490 - Manual (Page 11)

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
System Password
Option Settings
You cannot change or enter a new system password if either of the following two options is displayed:
l Set — A system password is assigned.
l Disabled — The system password is disabled by a jumper setting on the system board.
You can only assign a system password when the following option is displayed:
l Not Set — No system password is assigned and the password jumper on the system board is in the enabled position (the default setting).
Assigning a System Password
To escape from the field without assigning a system password, press <Esc> at any time before you complete step 5 .
1. Enter the system setup program (see System Setup ) and verify whether an Unlock Setup field is present under Security.
2. If the Unlock Setup field is present:
a. Use the arrow keys to navigate to the Unlock Setup field.
b. Press <Enter> to access the field.
c. Type in the administrator password and press <Enter>.
3. Use the arrow keys to navigate to the System Password field, and then press <Enter>.
4. Type your new password into the New Password field.
You can use up to 15 characters. To erase a character when entering your password, press <Backspace> or the left-arrow key. The password is not
case sensitive.
Certain key combinations are not valid. If you enter one of these combinations, the speaker emits a beep.
As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.
NOTE: Before you purchase an antitheft device, make sure that it works with the security cable slot on your computer.

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.
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.
