What?

TPM is short for Trusted Platform Module.

It is a small component of the Trusted Computing concept. TPM can support public key operations and (temporary) key storage, to offload some encryption work and make storage of keys a little more secure.

It can be plugged into motherboards and laptops, and may be built in (fairly common in business laptops).



"Can't detect TPM device"

Means the BIOS is knows that you can plug in a TPM module, and looking for it, and you don't have one.

Some BIOSes can be told not to look for it. It's often under a header named something like 'Trusted Computing'

Some BIOSes will always look for it(verify), in which case you can just ignore the message.
