New Motherboard, New Problems

One of our information security auditors recently had the motherboard on his laptop replaced to fix the "shutdown on its own" issue he'd been having for a while.  When he got the laptop back, his BIOS level fingerprint logins (to unlock the hard drive and BitLocker key) were no longer working.  Also, the x64 VMware machine he uses for audits would no longer boot.  The VM issue was pretty clear.  The CPU virtualization setting in the BIOS was disabled and needed to be turned back on.  The fingerprint issues, however, took a little more digging to figure out.  Eventually we realized the TPM on the new motherboard was not activated.  Once we activated and initialized the TPM, then turned BitLocker off and back on (without decryption), all the pre-boot login information unlocked by the fingerprint started working again.
