, you can either clear it through the BIOS settings if known, use a master recovery code from Dell Support, or use a third-party generation tool like bios-pw.org. Unlike older desktop models, modern Latitude laptops like the 5520 often rely on software-based release codes rather than physical motherboard jumpers for security. Method 1: Resetting if Password is Known
If you have the current password but want to remove or change it, use the internal BIOS utility:
Enter BIOS: Restart the laptop and press F2 repeatedly at the Dell logo.
Navigate to Security: Locate the System Security or Security section.
Clear Password: Select the System Password or Setup Password option.
Remove: Enter the current password, then leave the "New Password" fields blank and press Enter.
Save: Press Esc, then select Y or "Save and Exit" to confirm. Method 2: Resetting a Forgotten Password
If the password is lost, you must generate a release code based on your system's unique identifier.
Generate an Error Code: Turn on the computer and enter an incorrect password 3-5 times until a "System Number" or "Service Tag" and a hash code (e.g., 8FC8) appear on a black or gray screen.
Contact Dell Support: Provide your Service Tag and the error code to Dell Technical Support. After verifying ownership, they will provide a specific release code.
Third-Party Generators: Sites like bios-pw.org allow you to enter your Service Tag and hash to generate a master password for free.
Entering the Code: When back at the password prompt on your Latitude 5520, type the release code carefully. You must hold the Ctrl key and press Enter to submit the master code; clicking "OK" with the mouse may not work. Hardware Considerations
Motherboard Jumpers: While some Dell manuals mention a "PSWD" jumper, this is typically for desktops. Laptops like the Latitude 5520 may not have an accessible jumper for this purpose.
CMOS Battery: Removing the coin-cell battery generally does not reset the BIOS password on modern Latitude series laptops, as the password is stored in non-volatile memory (NVRAM). How to Reset, Remove, or Recover BIOS Passwords | Dell US
If you search eBay or AliExpress for "Dell Latitude 5520 BIOS password reset," you will find vendors selling a small USB device or a "dongle." These are not USB drives. They are specialized hardware tools that act as a Raspberry Pi Pico or an Arduino programmed to inject a key sequence.
How these dongles work: They emulate a USB keyboard. When plugged in during boot, they send a specific key combination (usually CTRL+ENTER or a vendor-specific hex code) to force the BIOS into recovery mode, wiping the password hash.
Legitimate use: Dell authorized service providers use a tool called the "Dell BIOS Recovery Tool" (DBRT).
Risk: 90% of third-party dongles are scams for the 5520. Because the 5520 uses encrypted SPI flash, a simple USB dongle cannot decrypt the password. Do not pay $50 for a USB stick.
If you manage to guess the password or receive a master code from Dell, you must fully disable it to prevent being locked out again.
Q: Can I just reinstall Windows to remove the BIOS password? No. The BIOS password is independent of the hard drive. Even with a new SSD, the password remains.
Q: Will updating the BIOS remove the password? No. Updating the BIOS preserves EEPROM data, including passwords.
Q: I see "Admin Password" and "System Password" – what is the difference?
Q: My keyboard is not working on the password screen (Latitude 5520 specific). The 5520 has a known firmware bug where USB-C docks interfere with keyboard input on the password screen. Disconnect all docks and USB hubs. Use the built-in laptop keyboard only.
If the above methods do not work, you can contact Dell support to reset the BIOS password. Here's how to do it:
