A CF1B generator did not help?
Check whether the tool lists CF1B and whether you entered the complete code from an Admin/Setup screen. No result is not a diagnosis, and a result from a different code is not interchangeable.
What to check when a generator does not help
Where to find the full BIOS code
- First 7 characters
XXXXXXX- Last 4
CF1B
- 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.
- For example,
XXXXXXX-CF1Bhas two parts: enterXXXXXXXin the code field and chooseCF1Bas the suffix. Do not add the ending twice. - 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

If Windows starts and the password is asked only when you open settings: shut down, turn on, and tap F2 several times (Dell). The same password screen opens. System Number is on that screen, not inside the BIOS menu.

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.
