    Hello all! First posting here but a long time subscriber to Windows Secrets (and the Langa List before that).

    I have an HP2730 that was turned in by one of our users. The BIOS password is set on it but is unknown to us and the user apparently doesn't remember what it was. Normally, with most other computers, we'd just remove the battery and CMOS battery and let it sit overnight and the next morning put everything back in and start fresh.

    Not so this little devil (we've tried every permutation of this that we can think of, without success). The BIOS password is apparently stored in an EEPROM and therefore, non-volatile. HP apparently has some sort of crack that they will run against the system for $89 but they don't guarantee it'll work. If it doesn't work, they will replace the motherboard for an additional cost. (Apparently the $89 is for only trying the crack, not applied to anything else.)

    Given my new-found access to this board, I thought I'd run it up the flagpole and see who, if anyone, salutes.

    Thoughts?

    That's damn good security, but I wonder what sort of crack they had in mind??

    See if How to Break a BIOS Password - wikiHow helps.

    Thanks for those tips. We tried taking the battery out (overnight) without success.

    But we'll give these latest ones a try.

    It's turned into a sort of quest now.

    You might want to take a look here for information on manufacturer created backdoor passwords. perhaps that is what HP wants $89 for ??


    If there is no joy there, take a look at this Google search for other possibilities. HTH

    Some motherboards have a 3 pin Bios reset jumper that you can short it by removing the jumper from the 1st & 2nd pins & place it on the 2nd & 3rd pin for a few seconds & replace it to the original position. The Bios should go back to the original factory settings. Otherwise just remove the battery & replace it with the polarity reversed - turn it upside down. That will do the trick. If that doesn't work - start praying.
