Windows 10: How do I reset BIOS to get rid of admin password

I have a dell latitude 7280 that I recently fixed, and I put an admin password in and I wrote it down but for some reason when I booted my laptop it wouldn't let me into windows with the correct password and just keeps saying invalid password, how would I reset BIOS to get rid of this password, I've tried dell manuals many times but it just won't work and I don't want to make a recently fixed laptop by me completely useless again after I spent a bunch of money on it

Resetting Bios Password

I am doing some spring cleaning, getting rid of old desktops, laptops, and routers. Regarding the computers, I am wanting to wipe the hard drives with Darik's Boot and Nuke software. When I booted up one old Dell desktop from 2001, I learned that it requires a BIOS password. Why I ever put one on is beyond me. Unfortunately, I have forgotten the password. The rest of this message will be about wanting to know if my understanding for resetting the BIOS password is correct.

Technically, this thread/message isn't about Windows 10 specifically. But it does relate to hardware, and I am hoping that it would apply to a significant number of computers, so I hope this message is okay.

I called Dell, and the technician said that I needed to reset the jumper on motherboard to reset the BIOS password. After opening the case on my old Dell computer and hunting on the internet, this is the what I think I have learned. I will present photograph of a portion of the motherboard.





I have put a red rectangular box around what I think is the jumper for the BIOS. I note that "PASS" is written on the motherboard beside those three pins.

I believe these are steps I need to follow. Please correct me if I am wrong.

1. Turn off and unplug the computer. (It has been off and unplugged for about ten plus years. I just plugged it in today. I am not sure if this information is relevant. Perhaps it helps with regard to the motherboard's battery.)
2. Open the case and locate those "PASS" pins again.
3. Switch the jumper from the current two pins to include the third pin and middle pin. Leave it there for 5 seconds or more. In other words, move the jumper over one pin for a few seconds.
4. Reset the jumper back to its original position with the original pins.
5. Plug in the computer, and attempt to boot it up.
6. Assuming it boots up, open CD tray and put in Darik's Boot and Nuke software and follow the steps.

Is there any information that I am missing? Do I have the correct location for the jumper? Are my steps correct?

Thank you for your help.
