Manufacturing Mode activated and can’t be disabled

To deactivate Manufacturing Mode on a Dell laptop, follow these steps carefully:

🛠️ Method 1: Disable via BIOS Setup

1. Restart your laptop.
2. Immediately press F2 when the Dell logo appears to enter BIOS/System Setup.
3. Once inside BIOS, press Alt + F to disable Manufacturing Mode.
4. If prompted, enter your Service Tag (usually found on a sticker on the bottom of your laptop).
5. Save changes and exit BIOS.
6. Restart your laptop to confirm the mode is disabled.

If the message “Manufacturing Mode is Detected” still appears, repeat the steps above.

🧩 Common Cause: Missing Service Tag

Manufacturing Mode is often triggered when the Service Tag is not programmed in BIOS. If the tag is missing or not saving:

• Try updating to the latest BIOS version from Dell’s official support site.
• Re-enter the Service Tag in BIOS and apply changes.
• If BIOS refuses to save the tag, it may indicate a motherboard issue or firmware bug.

🧪 Alternate Shortcut

Some users report success using:

• Fn + X during boot to exit Manufacturing Mode
