Power-On Password - Aptiva (SL-A) 2139/53/58/63


  Power-On Password


A power-on password denies access to the system by an unauthorized user when the system is powered on. When a power-on password is active, the password prompt appears on the screen each time the system is powered on.
The system starts after the proper password is entered. See 'Power-on Password' for more information about how to change, remove and set password in BIOS Setup.

In some cases, you might be required to service a system with an active and unknown power-on password. To clear a password from the system, follow these steps.

  1.  Turn off system unit.
  2.  Unplug power cable from the electrical outlet.
