Recently i bought a used laptop for typing when i'm on the go; its a Dell CPi. I can't get it to fully boot because it demands some sort of password. what it exactly says is this:

"This computer system, #VMSVZ**-D35B, is protected by a password authentication system. You cannot access the data on this computer without the correct password.

Please type in the primary or administrator password and press <Enter>"

I have no way to prove to the Dell corp. that i bought this from them (because i didn't), and this thing is immune to internal battery removal. Anyone have an idea of how i can get by this?
