Clearing Notebook & Desktop BIOS Passwords


What is a BIOS Password?

BIOS level passwords are designed to be the first line of defense against unauthorized access to a system. If set, a user will be required to enter a password before a system has even begun entering Windows. While passwords at this level can provide excellent security benefits, it’s not as straight forward to reset as other passwords may be if they are forgotten.


How to Unlock

Depending on your systems model, unlocking can be performed through several different means. Many Dell Desktops and older notebook systems can have BIOS passwords reset by removing CMOS batteries and adjusting password jumpers (see Article ID: 600157 & Article ID: 52016 below) while modern notebooks and tablet systems will require you contact Dell Technical Support for a ‘Master password’ to be generated.

If contacting support for a master password you will be required to verify your ownership of the system before a password can be generated. Due to the value Dell places on our customers' privacy and security, Dell will not provide a BIOS or hard drive password unless ownership of the system has been properly verified. To make the process as simple as possible have as much of the following information available as possible before contacting support:

·         First and Last Name on the Account

·         Company Name (if applicable)

·         Phone Number (including area code)

·         Street Address, City , State and ZIP

·         Email Address


Transferring Ownership

If your system was purchased recently or the original account information does is not up to date with your details you can request Dell update the systems records by completing an ‘Ownership Transfer’ form.
