The only way I know of off hand to reset the bios and get rid of the password for the bios is to remove the cmos battery which will clear any password(s); and reset the bios to factory defaults. Im not as familiar with laptops as desktops; however; the cmos battery will definitely be on the system board. But you have to open it up by carefully taking the top case off; and in there somewhere should be the cmos battery.

Contact the person you bought it from and get the password.

You cannot reset a Dell BIOS password by any method without removing a chip on the mobo.

This is a security feature since BIOS-locked PC's are often corporate and buying one is risky since its probably stolen or it wouldn't be locked.

I would return it, insist that eBay give you your money back or complain to PayPal which should protect you.
