Certain key combinations are not valid. If you enter one of these combinations, the speaker emits a beep.
To erase a character when entering your password, press <Backspace> or the left-arrow key.
4. Press <Enter>.
If the new system password is less than 32 characters, the whole field fills with placeholders. Then the option heading changes to
Verify Password, followed by another empty 32-character field in square brackets.
5. To confirm your password, type it a second time and press <Enter>.
The password setting changes to Enabled. Your system password is now set; you can exit System Setup and begin using your
system. Note, however, that password protection does not take effect until you reboot the system by pressing the reset button or by
turning the system off and then on again.
Using Your System Password to Secure Your System
Whenever you either turn on your system or press the reset button, or when you reboot the system by pressing the <Ctrl><Alt><Del> key
combination, the following prompt appears on the screen when Password Status is set to Unlocked:
Type in the password and
- press <ENTER> to leave password security enabled.
- press <CTRL><ENTER> to disable password security.
Enter password:
If Password Status is set to Locked, the following prompt appears:
Type the password and press <Enter>.
After you type the correct system password and press <Enter>, your system boots and you can use the keyboard and/or mouse to operate your
system as usual.
If you enter a wrong or incomplete system password, the following message appears on the screen:
** Incorrect password. **
Enter password:
If you again enter an incorrect or incomplete system password, the same message appears on the screen.
The third and subsequent times you enter an incorrect or incomplete system password, 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 you to an unauthorized person attempting to use your
system.
Even after your system is turned off and on, the previous message is displayed each time an incorrect or incomplete system password is entered.
Deleting or Changing an Existing System Password
To delete or change an existing system password, perform the following steps:
1. Enter System Setup by pressing <F2>, and verify that Password Status is set to Unlocked.
2. Reboot your system to force it to prompt you for a system password.
3. When prompted, type the system password.
4. Press <Ctrl><Enter> to disable the existing system password, instead of pressing <Enter> to continue with the normal operation of your
system.
NOTE: To escape from the field without assigning a system password, press <Tab> or the <Shift><Tab> combination to
move to another field, or press <Esc> at any time before completing step 5.
NOTE: If you have assigned a setup password (see " Using the Setup Password Feature "), the system accepts your setup password as
an alternate system password.
NOTE: You can use Password Status in conjunction with System Password and Setup Password to further protect your system from
unauthorized changes.
