Updating Bitlocker After Motherboard Replacement

This article provides instructions on how to update the TPM for BitLocker after a motherboard replacement. This is required when you have BitLocker enabled on a drive and you have had the motherboard replaced, and on boot-up, you are prompted to re-enter your BitLocker Recovery Key.

  1. Re-enable and activate the TPM in the BIOS.
  2. Boot the computer and enter the recovery key.
  3. Log in with an administrator account.
  4. Under Control Panel, open the BitLocker applet.
  5. Click on Manage BitLocker.
  6. Select suspend BitLocker.
  7. Restart the computer.
  8. At this point, you should no longer need to enter the recovery key. After restarting, log in as an administrator once more.
  9. Go back to Manage BitLocker and re-enable or unsuspend BitLocker. This will update the TPM chip with the correct recovery key.
