The client/owner must contact Dell.  There is no "generic" password.

Login any available computer which can allow you download. Insert a blank CD . Find Windows Password Key and download it, burn the iso image file to the cd. When finish, insert the disk to your computer, restart your computer, set the bios so that the computer boot from CD. Then you can clear your account password without knowing the current password.

There is an algorithm program out  created by russian hackers  which will generate a new admin password based on the service tag of a dell machine but for security purposes I cannot reveal it in case you are not who you say you are and have a stolen machine

Your best bet is to contact Dell Tech support with proof of ownership and they will unlock it for you

There is no other way to do it since the code get burned into the machine's PROM and shorting jumpers or removing the CMOS battery will not clear it!

op is not referring to a windows password but rather a password set in the BIOS

You need to call Dell, verify your system ownership and they'll generate the  master password for the system.

The call is free only in warranty - if you're out of warranty, there's a charge for the call.

I have the same problem... i wonder if i have to call dell support so that they can create a system password for me... Thank you for all your time and attention..

Hope you have a nice night.. Centrar Standar Time here..
