  1. I know that this subject has been rehashed over and over here, but I still
    have a question....

    If I've never entered a password of any kind in my TP600, why am I asked for
    one to access the bios setup to reset the date/time after a cmos battery

    I've cleared any power on password according to the hardware maint. manual,
    and the "icon" that appears when asking for the password isn't the one for
    the harddrive password (the "icon" for the power-on and supervisor passwords
    being identical to each other, (thanks IBM)), so it appears to be a
    supervisor password that it is looking for. But there has never been a
    supervisor password (or any, for that matter) set on this laptop.

    I've already swapped out the system board to resolve this....it just bugs

    A couple of months back I ran into similar situation, whereby my Supervisor
    password was "altered", due to the removal of my CMOS battery. The
    prevailing theory put forth was that pulling the battery might cause an
    electrical spike that might impact chips other than the CMOS chip. Hence,
    whichever chip holds the SVP may have been corrupted by said spike.
    Perhaps this is what happened to you, although it's just a theory.

    In case you're interested in reading the reference thread for this, it can
    be found on Google - Subject: "Supervisor password", around the end of May.
