HP Compaq 6005 Pro Business PC USDT - Password Security and Resetting CMOS

This computer supports security password features, which can be established through the Computer Setup Utilities menu.
This computer supports two security password features that are established through the Computer Setup Utilities menu: setup password and power-on password. When you establish only a setup password, any user can access all the information on the computer except Computer Setup. When you establish only a power-on password, the power-on password is required to access Computer Setup and any other information on the computer. When you establish both passwords, only the setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to the information on the computer by resetting the password jumper.
  caution:
Sliding the CMOS switch will reset CMOS values to factory defaults. It is important to back up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup.

Resetting the Password Jumper

To disable the power-on or setup password features, or to clear the power-on or setup passwords, complete the following steps:
  1. Shut down the operating system properly, then turn off the computer and any external devices, and disconnect the power cord from the power outlet.
  2. With the power cord disconnected, press the power button again to drain the system of any residual power.
      warning:
    To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
      caution:
    When the computer is plugged in, the power supply always has voltage applied to the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.
    Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. See the Safety & Regulatory Information guide for more information.
  3. Remove the computer cover or access panel.
  4. Locate the header and jumper.
    note:
    The password jumper is green so that it can be easily identified. For assistance locating the password jumper and other system board components, see the Illustrated Parts & Service Map (IPSM) for that particular system. The IPSM can be downloaded from http://www.hp.com/support.
  5. Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.
  6. Replace the computer cover or access panel.
  7. Reconnect the external equipment.
  8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current passwords and disables the password features.
  9. To establish new passwords, repeat steps 1 through 4, replace the password jumper on pins 1 and 2, then repeat steps 6 through 8. Establish the new passwords in Computer Setup.

Clearing and Resetting the CMOS

The computer’s configuration memory (CMOS) stores information about the computer’s configuration.
The CMOS switch resets CMOS but does not clear the power-on and setup passwords.
  1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.
  2. Disconnect the keyboard, monitor, and any other external equipment connected to the computer.
      warning:
    To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
      caution:
    When the computer is plugged in, the power supply always has voltage applied to the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.
    Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. See the Safety & Regulatory Information guide for more information.
  3. Remove the computer cover or access panel.
      caution:
    Sliding the CMOS switch will reset CMOS values to factory defaults. It is important to back up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup.
  4. Slide the CMOS switch.
    note:
    Make sure you have disconnected the AC power cord from the wall outlet. The CMOS switch will not clear CMOS if the power cord is connected.
    note:
    For assistance locating the CMOS switch and other system board components, see the Illustrated Parts & Service Map (IPSM).
  5. Replace the access panel.
  6. Reconnect the external devices.
  7. Plug in the computer and turn on power.
    note:
    You will receive POST error messages after clearing CMOS and rebooting advising you that configuration changes have occurred. Use Computer Setup to reset any special system setups along with the date and time.
