Bios password reset on a Dell XPS 1530. Bios reset software will not work for you cannot boot from disc while a bios password is implemented. Removing CMOS battery overnight does not work either.

BIOS passwords can be reset in two ways:

1. using software 2. using hardware.

I would first try resetting using software, here are two software apps to reset or retrieve BIOS passwords.

If you are not used to working inside computers, start with "Removing the computer cover", then go to "System Setup" and click on "Clearing Forgotten Passwords".

Another method is to unplug the power cord and remove the CMOS battery for a 1/2 hour or so. For details on how to do that, try this website:

Most laptop or notebook computers feature enhanced BIOS security, and BIOS passwords on laptops are hard to bypass. Several companies offer laptop security chip services that can be used to bypass the BIOS password on Dell laptops or notebooks and reset the security. They can provide a master password from the Dell Service Tag of your Dell laptop. This master password will allow you to bypass the existing password and enter the BIOS and reset the unknown password. To generate the master password they need to know the Dell Service Tag of your unit. Dell Master Password Recovery does not require soldering or disassembly of the laptop and supports most Dell models.

Dell BIOS passwords can also be reset by replacing the laptop security chip. Passwords can also be recovered from security chips that have been removed from laptop or notebook systems. These passwords may be required to attempt to unlock protected hard disks. Passwords recovered from these chips are the original BIOS passwords and may be the same as the hard disk password, but are not guaranteed to be the same and may not unlock the hard disk.These are usually damaged in the process of recovering the passwords and are not suitable for replacement into a computer.

usually the bios password is 0000 by default
