Power-on password
A power-on password denies access to the computer by an unauthorized user
when the computer is powered on. When a power-on password is active, the
password prompt appears on the screen each time the computer is powered on.
The computer starts after the proper password is entered.
Removing a power-on password
To service a computer with an active and unknown power-on password, power-off
the computer and use the following procedure.
Note: On some models, this procedure will also remove the administrator password.
1. Unplug the power cord and remove the top cover.
2. Refer to “Identifying parts on the system board” on page 44 to find the Virtual
clear CMOS/BIOS recovery jumper.
3. Move the recovery jumper from normal to ROM recovery .
4. Power-on the computer. The system senses the change in the position and
erases the password.
5. Wait 30 seconds for beeps to sound, and then power down by holding the
power button for 10 seconds.
6. Return the jumper to normal position.
7. Reset the date and time and remind the user to enter a new password when
service is complete.
Administrator password
The administrator password is used to restrict access to the Configuration/Setup
Utility program. If the administrator password is activated, and you do not enter
the administrator password, the configuration can be viewed but not changed.
