The BIOS controls the startup operation on your Dell PC; if you set a password to lock the BIOS, your laptop won't initialize the bootstrap process unless you enter the appropriate password. The feature is ideal for keeping out unauthorized users -- up until you forget your credentials. If you still know your password but want to remove the access restrictions from your Dell Latitude, you can do that in system setup. If you don't remember your password, however, you must enter a backdoor code to bypass the lock or consult Dell for support.
Step 1
Turn on the Latitude and then type your existing password into the prompt to unlock your PC.
Step 2
Press 'F2' repeatedly on the Dell logo screen to access system setup. If you set a supervisor password, type the password at the prompt and then press 'Enter.'
Step 3
Scroll down to and select 'System Security' using the cursor keys. Press 'Enter.'
Step 4
Highlight 'Password Status' and then press '+' or '-' to toggle the option to 'Unlocked.'
Step 5
Select 'System Password' and then press 'Enter' twice to clear the password. If you set a supervisor password, select 'Setup Password' and press 'Enter' twice.
Step 6
Press 'Esc,' then 'Y' to save your changes and exit the BIOS.
Step 1
Turn over your Dell Latitude and locate the 10-digit service tag on the bottom of the computer.
Step 2
Sign on to another PC and browse to the BIOS Master Password Generator for Laptops website (link in Resources).
Step 3
Enter your service tag into the available field and then click 'Get Password' to see the list of backdoor passwords for your BIOS.
Step 4
Write down the password listed next to 'Dell by Serial Number.' Turn on your Latitude and enter this password into the prompt to bypass the lock.
Tip
- If your service tag is only seven digits long, append '-595B' to the tag and write down the resulting password. Repeat for '-D35B' and '-2A7B.' Try each generated password to see which one works.

The basic input/output system acts as a bridge between the operating system and the PC's internal components. You can access the BIOS at boot using an administrative password, and change the settings associated with system hardware. The administrative password prevents unauthorized users from accessing the system or making changes to the BIOS. If an employee locked the BIOS without your permission, or if you forgot the password to log in to your computer, use a backdoor password to access system setup. Motherboard and computer manufacturers sometimes include these master passwords so that repair technicians can access the PC in case the BIOS is locked.
1.
Navigate to the computer or motherboard manufacturer's website on an alternate PC.
2.
Look up the computer or motherboard model and review the specifications, user guide or BIOS drivers to find out which BIOS manufacturer the computer uses.
3.
Turn on the locked computer. If the make of the computer is Dell, Compaq or Toshiba, type the name of the manufacturer and press 'Enter.'
4.
Try the master passwords 'BIOS,' 'CMOS' and 'PASSWORD.' If these don't unlock the BIOS, try using a password specific to the BIOS vendor: use 'phoenix' and 'PHOENIX' for Phoenix BIOS; 'AAAMMMIII,' 'AMI?SW' and 'A.M.I.' for AMI; and 'AWARD PW,' 'AWARD SW' and 'AWKWARD' for Award BIOS.
Tips
- Passwords are case-sensitive. For example, 'PHOENIX' in all caps is not the same as 'phoenix' in lowercase.
- Review the link in the Resources section to see other master passwords you can use to access and change the BIOS. If none of the listed passwords work, contact the computer or motherboard manufacturer for more assistance.
