I changed my bios admin password with help from Dell. I have an Inspiron 15 3537 Laptop and had restart problems, so went searching, found bios info, called Dell Tech. They tried to help me, but would not give me the bios admin password.
Yesterday, I found this link, read the info about not giving passwords out in the forum and scrolled down and found the option to email, so I did.
I told the gal who helped me my problem, she asked for my Service Code number and other verification info, then she asked for my error numbers. One of the error numbers was my service code number, (find it on the bottom of the Inspiron, white sticker), which was in the bottom rectangle of the popup error box. The other number was 16 digits and was listed above the service code number. Note...I found the error code numbers a few weeks ago, and thankfully wrote them down from one of my bios errors while trying to set a new password.
She told me Dell would email me my Password to unlock my BIOS within 24 hours. I received it this morning.
To reset the password, shut down the Inspiron 15, to restart in bios, press and hold F2 until it loads in the long rectangle box.
The InsydeH20 Setup utility will open.

On restart, I received error message and selected RESTART.
It restarted properly..
There you go.
I hope I have helped someone with my instructions.
I was at the point that this was a no-fix problem. I learned more about the bios than I think I needed to know, but guess I could say it was quite a learning experience at my age of 69. Love computers, internet, technology and was born too soon!
