DELL BIOS / CF1B

Dell CF1B BIOS password recovery solution

CF1B is the suffix to select when those four characters appear at the end of your Dell BIOS password prompt. BIOS Zone accepts recovery requests for this suffix in its Telegram bot.

ABCDEFG-CF1BIllustrative format only. This is not a working code.

Read C–F–1–B: letter C, letter F, digit one, letter B. The third position is 1, not the letter I; the final character is B, not 8.

Read the password screen

Keep the final B when transcribing CF1B. If the screen is difficult to read, resolve that uncertainty before requesting recovery rather than selecting a suffix from the model list.

Choose the page that matches the screen, even if the same model appears elsewhere. The model list gives context; use the displayed code for your request.

The same model can show a different suffix

Latitude 3510 also appears in these model lists. Open the page matching the ending on your own screen.

Request a recovery password

In the bot, choose the suffix and send the seven characters before the dash or the full displayed tag. Review support status and price, then pay. The bot sends the Recovery Report PDF automatically after payment confirmation.
