IBM T40, power-on/supervisor password and "lock settings against changes" in BIOS setup

Discussion in 'IBM Thinkpad' started by Andrej Komelj, May 30, 2004.

  1. I have power-on and supervisor password set on my T40 Thinkpad
    notebook. Both passwords are set to the same keyword (yeah, stupid
    me...). In addition, I have enabled the "lock BIOS settings against
    changes" in the BIOS setup utility. As a result, I am unable to reset
    my supervisor or power-on passwords, as the setup utility does not
    allow me to perform any changes. It appears the "lock settings"
    feature works too well. :)

    When entering the BIOS setup utility, I get a (supervisor?) password
    prompt. By entering the password, I get access to settings menus but I
    am not allowed to make changes to ANY of them. Is there any way to
    change the settings?

    Dredge the depths of your memory to try to remember if you _did_ in fact set
    both PWs the same.

    What you're seeing would be the normal result of being in the BIOS with the
    correct POP, but not being able to change anything because you haven't
    entered the correct SP!

    Open the laptop and get to small battery supplied power to bios memory and
    disconnected it for 10 seconds .Reconnected it and power up.

    Hi Andrej,
    please try to locate and download the HW Maintenance Manual for
    Your T40 from www.ibm.com support sites.

    That will clear the Power On Password (POP), but will have _NO_ effect on
    the Supervisor Password (SP) and will result in a completely unusable

    Sorry for piggybacking; the original article never showed up here. Also,
    this is likely quite old.

    Check out the links near the bottom of
    http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/README.thinkpad . Replacing
    the EEPROM may be the only way to regain access to the BIOS.
