Very interesting. Assuming the conclusions noted above are correct, this implies there was a production run as late as Jan '17. Perhaps the refurbished units, if done by HP, are issued a new serial number during the refurb. process, which would likely be needed for warranty period verification.

@ctrclckws - Can you check your unit at the HP warranty checker site to see what it says the warranty period is?
