Huh. I didn't know that. My particular laptop does have a "pro" CPU. However, I would be surprised to no end to learn that it supports ECC. This particular model sports an MBP-level price tag [0], but is absurdly cheaply built. Even for "customer facing components", that are easy to compare, such as the screen (terrible colors) and case (creaks if you look at it wrong). HP doesn't offer ECC RAM, not even as an upgrade, so I really don't think the additional lines are physically present. --- [0] I don't remember the specific number, but it was within 100 € of a 14" M1 MBP with 32 GB RAM and 512 GB SSD. That's counting a RAM (8 -> 32) and SSD (256 -> 512) upgrade which were made with components bought separately (though they were rather high-end).
