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?
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.
To reset BIOS Administrator Password- If your Dell does not have a password reset jumper, or if removing the battery does not reset BIOS security try this-- 1)Unplug computer 2)remove jumper labelled PSWD 3)Replug power back. 4) with jumper out, boot to BIOS (F2) 5) BIOS is now unlocked. 6) change Administrator Password (under Security) 7) Start operating system. 8)Reinstall jumper. 9)reset time and date-- FAILURE to reset date and time will cause internet connection loss
Thanks a lot this was the only solution worked for me. Even though I was not able to change the admin password but it was disabled so I was able to update the bios without requiring to enter admin password.
I recommend everyone to try this and it will most possibly work.
