HP TouchSmart 9100 Business PC - Clearing BIOS passwords

Clearing BIOS passwords

If a user has configured a power-on or setup password using the BIOS and then loses the password, they cannot access the BIOS in order to change or clear the password.
In this event, to clear the power-on or setup passwords—or to disable the power-on or setup password feature—users need to perform the following steps:
  caution:
Before attempting to remove or touch any parts from the motherboard, check that the power cord is disconnected from the electrical outlet. Failing to do so can cause hardware damage and even physical injury.
  1. Shut down the operating system and turn off the computer and any external devices.
  2. Disconnect the power cords of the computer and any external devices from the power outlet.
  3. Disconnect any external devices that are connected to the computer.
  4. Remove the chassis cover.
  5. Locate the BIOS password jumper header on the motherboard.
      caution:
    Removing the incorrect jumper can cause the system configuration to be changed or even cause irreparable hardware damage.
  6. Move the jumper to cover the middle and third pins for at least five seconds. This clears the current passwords.
  7. Replace the jumpers in their default positions.
  8. Replace the chassis cover.
  9. Reconnect the external equipment.
  10. Plug in the computer and turn on the power. Allow the operating system to start.
