Clearing Administrator Password -Optiplex 760

This question is answered
OK I have followed the instructions on Dell's website:

http://support.dell.com/support/edocs/systems/op780/en/sm/sm_usff/bios.htm#wp1163645

I need to change/delete the administrator password because the systems
guy has passed away and I need to change the boot order on one of the machines so that we can
perform a clean install of the operating system.

I removed the jumpers as described in the instructions but nothing
changed.  I also removed the bios battery CR2032 and this too didn't
change anything.

Can I remove the battery and leave the machine un-powered for 24 hours
to wipe everything that is hard coded in the bios?  Or can somebody tell
me where else is the power coming from to keep remembering the
passwords?  There must be a way of wiping everything to get me going.

I thought I will flash the bios if this would work but I can't boot from
any media because the first media it looks for is HD and I can't change
anything without the Administrator password.

Please note: this question is about Bios' Administrator Password (NOT Windows Administrator Password).

I posted a similar question on Microsoft Newsgroup but they don't have a clue about this.

Thanks.

  • Hi,

    Welcome to the community

    If you try the steps on the link you provided it should work right away. Did you perform the steps on clearing the CMOS settings? You can try to remove the Coin Battery for a long period of time. Remove all cables attached to the motherboard. Including Rams. Then re-try again. If same thing happens, possible motherboard issue.

    Let me know if you need further assistance, glad to help!

  • Hi

    I have a similar problesm on my DEll Optiplex 780. I removed the coin battery for 10-15 minutes and it did not clear the password. Which cables do I need to remove?

    Thanks

  • There is a blue Jumper next to the main Power Adapter coming from the Power Supply . The Jumper is labeled pswd1 . Unplug the jumper and boot the computer. You will get a message on the screen password disabled.
