Chapter 8. Additional Service Information Security features Security features in this section include the following: v Passwords v Vital Product Data v Alert on LAN Passwords The following section provides information about computer hardware and software-related passwords. v Power-on Password v Administrator Password v Operating System Password Power-on and Administrator passwords are set in the Setup Utility program. See Chapter 5, "IBM Setup Utility program," on page 19 for information about running the Setup Utility. 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 (all machine types)" on page 38 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 IBM 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. © Copyright IBM Corp. 2005 111
