[ the default setting for most TPMs for excessive wrong passwords is to completely lock down the TPM until it’s administratively cleared from the BIOS.]

And in some cases...

“If the manufacturer of your computer has already placed a certificate in the TPM, and that certificate has expired, then when Windows 8 activates the TPM, your computer’s motherboard will brick itself.”

It never ceases to amaze me how stupid some supposedly-educated people are when it comes to certificates. There’s no such thing as a non-expiring certificate, so unless you’re setting it to expire in 50+ years, it’s going to blow up your system at some point.
