I changed the system board on my Dell Latitude D420 because of the on-board Ethernet port only working some of the time. After replacing the system board it is required to enable TPM again and activate it for Windows login.
First you will need to enable TPM in the BIOS.
- Open BIOS Settings: Reboot or start the computer you are working on and tap the button to enter the setup of your computer. On my Dell D420 laptop it is F2 to enter setup and typically is similar on other computers.
- Navigate to Security: Use the arrow keys to navigate to Security and expand the menu by clicking the right arrow. Now navigate to TPM Security and highlight it.
- Modify Setting: Now modify the TPM Security setting to read On.
- Save Settings: Move out of the TPM Security setting and exit the BIOS settings. You should be prompted to save the settings but this could depend on your BIOS and it may save the setting automatically.
After saving then reboot, open the Embassy Security Center, and then configure it.
- Launch Embassy Security Center: Launch the Embassy Security Center application so you can configure the proper settings.
- Enroll: Click on Windows Login in the left navigation of Embassy Security Center. Click on Enroll/Update Fingerprint. Your previous settings should already exsist and all it takes is enrolling again.
- Save Settings: Apply the settings and then close the Embassy Security Center.
- Test: Now reboot the computer and make sure that you are prompted for your Password or Biometric information for the computer to boot again.
That should be it. Your computer is now protected again and if someone steals it they will not even be able to boot the computer without your password or biometric information.Tags: biometric, BIOS, d420, Dell, Embassy Security Center, Ethernet, TPM, windows
