Overview

The password features provide a basic level of security for the data on the system. However, these features are not foolproof. If the system's data requires more security, it is the user's responsibility to obtain and use additional forms of protection.

The system is shipped with the system password feature set to Not Enabled, which allows the user to enter the system setup program and assign a password.

If system security is a concern, operate the system only with system password protection.

The user can assign a system password whenever using the system setup program. Once a system password is assigned, only those who know the password have full use of the system.

When the System Password category is set to Enabled, the computer system prompts the user for the system password just after the system boots.

To change an existing system password, the user must know the password.

If the user assigns and then forgets a system password, the user must remove the computer cover and change a jumper setting to disable the system password feature. Note that the setup password is erased at the same time.


Assigning a System Password

With a system password assigned, the status shown in the System Password category is Enabled. With the system password feature disabled by a jumper setting on the system board, the status shown is Disabled By Jumper. The user cannot change or enter a new system password if either of these options is displayed.

With no system password assigned and with the password jumper on the system board in the enabled position (its default setting), the status shown in the System Password category field is Not Enabled. Only when this option reads Not Enabled can the user assign a system password, using the following procedure:

  1. Turn on (or reboot) the system, and press <Del> to enter the system setup program.
  2. Press <Alt><p> to move to Page 2 of the system setup screens.
  3. Press <Tab> or <Shift><Tab> to highlight the System Password category.
    Highlighting the System Password category causes help information related to the current password status to appear in the Help window.
  4. If the current status displayed is Not Enabled, press the left- or right-arrow key.
    The category heading changes to Enter Password, followed by an empty 7-character field in square brackets.
  5. Type the new system password.
    The password can contain up to 7 characters.
    As the user presses each character key (or <Spacebar> for a blank space), a placeholder appears in the field.
    The password assignment operation recognizes keys by their location on the keyboard, without distinguishing between lowercase and uppercase characters. For example, if there is an "M" in the password, the system recognizes either "M" or "m" as correct.
    Certain characters are not valid. If an invalid key character is entered, a beep will sound.
    To erase a character when entering the password, press the <Backspace> key or the left-arrow key.
    To escape from the field without assigning a system password, press <Tab> or <Shift><Tab> to move the highlight to another field, or press <Esc> at any time before completing step 7.
  6. Press <Enter>.
    If the new system password contains fewer than 7 characters, the whole field fills with placeholders and the category heading changes to Verify Password, followed by another empty 7-character field in square brackets.
  7. To confirm the password, type it a second time and press <Enter>.
    The password setting changes to Enabled. The system password is now operational; exit the system setup program and begin using the system.

Using the System Password to Secure the System

The system password is used to protect the system. When the system is turned off and then on, or the reset button is pressed, the following prompt appears on the screen:

Type the password and ...


- press <Enter> to leave password security enabled.


- press <Ctrl><Enter> to disable password security.


Enter password:

After you enter the correct system password and press <Enter>, the system boots and the keyboard can be used to operate the system as usual.

If a wrong or incomplete system password is entered, the following message appears on the screen:

** Incorrect password. **


Number of unsuccessful password attempts: 1

Enter the password again. If an incorrect or incomplete system password is entered again, the same message appears on the screen.

The third time an incorrect or incomplete system password is entered, the system displays the following message:

** Incorrect password. **


Number of unsuccessful password attempts: 3


System halted! Must power down.

The number of unsuccessful attempts made to enter the correct system password can alert the user to an unauthorized person attempting to use the system.


Changing an Existing System Password

To disable an existing password, perform the following steps:

  1. Boot the system and type the password as usual, but press <Ctrl><Enter>.
  2. Enter the system setup program and confirm that Not Enabled is displayed for the System Password category of the system setup program.
    Reboot the system and press <Del> to enter the system setup program. Then press <Alt><p> to move to Page 2 of the system setup screens. If Not Enabled appears in the System Password category, go to step 3. If Not Enabled is not displayed for the System Password category, press <Esc> to exit the program and reboot the system. Then repeat steps 1 and 2.
  3. Assign a new system password.
NOTE: When the Password Status category is set to Locked, the system password cannot be changed or disabled at boot time by pressing <Ctrl><Enter>. To unlock the system password, the user must enter the setup password and then change the Password Status category to Unlocked. See Password Status.

Disabling a Forgotten Password

If you forget the system password, you will be unable to operate the system until disabling the password. Disabling the password involves going inside the computer and changing a jumper setting (twice) on the system board.

To disable a forgotten password, perform the following steps:

  1. Turn off the system and remove the cover.
  2. Move the jumper plug on jumper A to pins 2 and 3 to disable the password(s).
  3. Turn on the computer. Powering up the system with jumper A set to the disabled position erases existing password(s). Before assigning a new system password, you must reset jumper A to the enabled position.
  4. Turn off the computer.
  5. Place a jumper plug on pins 1 and 2 of jumper A to enable the password features.
  6. Replace the computer cover.
  7. To assign a new password, follow the procedure in Assigning a System Password.
