  1. i find it hard to believe that you installed windows 7 over xp without ever entering the existing bios password. the bios password is asked during every startup.
    to remove a bios password, you must enter the existing password first. it won't work otherwise.
    you could ask the owner of the pc.

    Hi

    I expect you will have to take your laptop to a Dell authorised dealer (or someone) who has the CD containing the password reset program(s)
    (and prove you own the laptop)

    With most Desktops the password is held in cmos memory and can easily be reset to blank

    With many business class laptops the power on passwords are held in eeprom or similar chip and require a model specific program to clear them.

    The hard disk power on password is even more difficult to crack, theoretically only a special program which erases the hard disk can clear the password


    Note on Dell laptops there are passwords for booting the PC, accessing the hard disk and another against changing any BIOS settings
