BitLocker prompting for recovery key.

If Your Trusted Platform Module (TPM) enabled Dell system has a motherboard replaced due to a No Power on Self-Test (POST) issue and you have BitLocker enabled within the Operating system, you will be required to enter their BitLocker Recovery key when booting to the Operating system.

NOTE: The BitLocker Recovery key may be enabled automatically after the motherboard replacement. For information on recovering or saving the BitLocker Recovery key, reference the following Dell Knowledge Base article: BitLocker is prompting for a Recovery key and you do not have the BitLocker key. If the motherboard is being replaced on your computer but the computer will still boot to the operating system, it is advised that you find your BitLocker Recovery key prior to the motherboard replacement. If your computer is equipped with the Trusted Platform Module (TPM) capability, it is also advised that you decrypt the hard drive before the motherboard replacement following the steps provided in the following Dell Knowledge Base Article: Automatic Windows Device Encryption/BitLocker on Dell Systems.
NOTE: This does not require an operating system reinstall or a hardware replacement.

This can affect systems with Windows 7 or Windows 8 or Windows 10.
