Dell CF1B BIOS password: models and recovery

CF1B is the four-character ending after the dash on a Dell BIOS password screen. It is part of the device code, not the recovery password. Use the complete on-screen code to check recovery options.

Where to find the full BIOS code

  1. Read the System Number on the Dell Admin password screen, sometimes headed Dell Security Manager. Use the screen rather than only the Service Tag sticker.
  2. For example, XXXXXXX-CF1B has two parts: enter XXXXXXX in the code field and choose CF1B as the suffix. Do not add the ending twice.
  3. If the code is missing or unreadable, send support a photo of the password screen before ordering. Send the screen photo on WhatsApp.

A Windows sign-in, BitLocker recovery key or HDD password is a different request. Compare the password screens.

Check the screen before continuing

For an Admin password that prevents changes to Dell BIOS settings. Not for System/power-on, Windows, drive or BitLocker passwords. Online service: no device shipping or remote access to your files. Recovery password for access to Dell BIOS settings and a PDF guide, sent by email after payment.

FAQ3
My Latitude 5400 shows 8FC8 instead of CF1B. Which guide applies?

Use the 8FC8 guide. Latitude 5400 and 5410 appear with both endings; the four characters on your screen decide which one to check.

Can I choose the suffix from the laptop model?

No. The same model can show different endings. Use the suffix on your own password screen, even when your model appears in another guide.

What if there is no recovery option for my code?

Check the full code and the type of password first. Dell Support can advise on recovery after verifying ownership; for a company-managed laptop, ask the IT administrator. Master Password Lockout can prevent reset by recovery password.
