When I registered it at hp.com after entering my serial number, the site told me the model number - which I expected to be 2AP18AA. But instead I got 4FJ23AA.

Hardware version in system help tells 'D'.

Though the code 4FJ23AA suggests a later version than 2AP18AA, I'd like to know for sure: Is it a later or an earlier version than 2AP18AA?

Anybody with a similar number?
Anything known about this model?

A quick google search for 4FJ23AA and it looks like the prime family has had a model number bump.
