    Do laptops have CMOS batteries?

    Yep, well this one did. It reset the date back to 2007, but not the password.

    If it is anything like a D520, the only answer is to speak to DELL; you will have to prove ownership & then they will talk you through the process to clear the password. At least it was free, which I understand is not the case for other manufacturers .....

    ring dell and ask for the master reset code for your machine

    sometimes you might need to fax them some information but they are pretty quick


    i have used them a few times

    There are some CMOS/BIOS clearing utilities on the UBCD that i have used to clear passwords before.
