Erasing a lost or forgotten password (clearing CMOS) - ThinkCentre A50, S50

This section applies to lost or forgotten passwords. For more information about lost or forgotten passwords, go to Access IBM.

NOTE: Some models have a POV daughter card installed on the system board. In these models, the password is stored in the EEPROM on the POV card and cannot be erased. See "Identifying parts on the system board" for the location of the POV card.

To erase a forgotten password

  1. Turn off the computer and all attached devices.
  2. Remove the cover. See "Removing the cover".
  3. Locate the Clear CMOS/BIOS recovery jumper on the system board. See "Identifying parts on the system board".
  4. If necessary, see "Installing PCI adapters" to remove any adapters that impede access to the Clear CMOS/Recovery jumper.
  5. Move the jumper from the standard position (pins 1 and 2) to the maintenance or configure position (pins 2 and 3).
  6. Install the PCI riser and adapters, if removed.
  7. Lower the drives and reconnect any cables that were disconnected.
  8. Close the cover and connect the power cable. See "Closing the cover and connecting the cables".
  9. Restart the computer, leave it on for approximately 10 seconds, and then turn off the computer.
  10. Repeat steps 2 through 4.
  11. Move the CMOS/BIOS recovery jumper back to the standard position (pins 1 and 2).
  12. Reassemble the computer and close the cover. See "Closing the cover and connecting the cables".
