Short answer: No.
Unlike older Dell Latitudes (E6440, E6540), the 5520 lacks a physical PSWD or RTCRST jumper. Dell has moved to a fully embedded controller (EC) managed password system.
If you cannot provide proof of ownership to Dell, the situation becomes significantly more difficult. There are hardware programming methods involving an external programmer (like a CH341A) and a clip to read the BIOS chip contents.
Dell provides a BIOS password reset tool that can be used to reset the password. Here's how to use it:
If you are the original owner (or can prove ownership with an invoice), Dell will reset the password for you.
The Dell Latitude 5520 is a robust business laptop featuring modern security protocols designed to protect sensitive data. However, if you have acquired a used machine or simply forgotten your BIOS password, you may find yourself locked out of the system firmware. dell latitude 5520 bios password reset
Unlike older laptops where removing a CMOS battery would reset the password, the Latitude 5520 stores the password in non-volatile memory. This means the password survives power loss. This guide outlines the official methods to regain access to your system.
The Latitude 5520 has Secure Flash and Boot Guard. If you corrupt the Intel ME (Management Engine) region during flashing, the laptop will never boot again—even with a soldering iron. You will have a $500 paperweight.
Bottom line: Unless you are a professional board repair technician, do not attempt this.

, 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: If the above methods don't work, you can
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. Dell provides a BIOS password reset tool that
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
