You are searching to activate the password authentication system in BIOS? Or to access to an already password protected system?

To activate the BIOS password system you just have to check in your BIOS settings for "Protect BIOS with password" or something similar.

To reset bios you can find in your PC/Laptop manual for the jumper config to reset BIOS or if it still works you can remove for a minute the BIOS battery.

To activate password auth in windows please tell wich windows.

Well , I Try to reset de BIOS unpluged the batery of bios, but is not a password BIOS is another kind of password, I get this computer in a Garage Sale so i dont know the data of the owner, so i cant contact the dell company.. is a white screen to the beginnin of the laptop startup, even if you enter the F2 key..
so i dont know if there is a Generic password from the company or i have to get into the motherboard of my computer.. what do you think..?
Did you tried booting on a bootable CD-ROM? Like Windows installation disc. To see if the password authentication is after BIOS process. If you can boot up with a bootable disc I suggest you reinstalling a new Windows!

Maybe the authentication system come from a third party software that is used to lock access to installed OS or maybe you're just facing an other OS than Windows! Like a Unix.

Nop, I can´t boot with a CD, because the boot secuence in Bios start with HD first, I already try to boot with a cd that contains a routine that flash the Bios password, but its not the first drive for Boot..
I cant reach the bios settings because this password came in first place.. so the question is How to get ride of this password..?
You will have to find in the manuals the reset BIOS jumper. If you can't access BIOS before the authentication screen then its a BIOS enabled protection.
