The Dell Latitude D420 is a business notebook computer with an Intel Core processor. A fingerprint reader is one of the optional components available for the Latitude D420, and if you have one installed, you will notice the scanning pad between the left and right mouse buttons. The software needed to use the fingerprint reader is coded into the hardware of the Latitude D420. To use the fingerprint reader, you must install the software from within the Latitude D420 motherboard set-up, before Windows loads.

Skill level:
Moderately Easy


  1. 1

    Restart the Latitude D420 if Windows is currently running. If the computer is off, press the power button.

  2. 2

    Tap the "F2" key repeatedly immediately after turning the computer on. After a moment, you should see the motherboard set-up screen for the Latitude D420.

  3. 3

    Highlight "TPM Security" under "Security" using the keyboard arrow keys and press "Enter."

  4. 4

    Highlight "On" and then press "Enter."

  5. 5

    Press "Esc," select "Save/Exit" and press "Enter" to restart the computer. As soon as the computer begins restarting, tap the "F2" key again until the motherboard set-up software appears.

  6. 6

    Highlight "TPM Activation" under "Security" and press "Enter."

  7. 7

    Highlight "Activate" and then press "Enter." The computer restarts. As the Latitude D420 restarts, tap the "F2" key again until the set-up software appears.

  8. 8

    Highlight "Wave EMBASSY Trust Suite" and then press "Enter."

  9. 9

    Press the "Esc" key, highlight "Save/Exit" and press "Enter." The computer starts. This time, allow Windows to load. Windows will now have a new program folder called "Wave Embassy TRUST Suite" on the Start menu. Launch the "Getting Started Guide" under the "Wave Embassy TRUST Suite" folder to learn how to use your Dell Latitude D420 fingerprint reader.

Tips and warnings

  • If the motherboard set-up software does not appear when you tap the "F2" key and Windows begins to load, do not shut the computer off, as turning the computer off while files are in use can result in data corruption. Allow Windows to load completely, and then restart the computer again.
