Louis is correct in the messages he dug up.
What happens is they have one motherboard for many different models and the recovery installs the proper drivers and S/W based on what it reads from the BIOS. For my Toshiba the same drivers are for many models. One might have a webcam or bluetooth, Different model number.
I have seen this issue in laptops where the person doing the motherboard swap did not set the proper information into the new motherboard.
When I replaced the Motherboard in my Toshiba I had to enter
Part number (AKA Model part Number)
If I hadn't done that then the recovery discs would not have worked. What they do is a set of recovery discs fits several models, IMO.
The recovery disc looks nto the Bios and confirms that the OEM string is one that it is for or else it says something like unsupported model.
Then when it finds a supported model it installs drivers and software based on what is proper for the model.
I've seen Dell somethung similar when they were here at work changing a motherboard under warranty.
I understand it works that way for Lenovo too.
You need to push HP, Back up your data before returning it for warranty. They should fix this problem even off warranty. It has to be a manufacturing problem or if they swapped the motherboard they didn't put the information into it.
If you could give them the information and software you could do it yourself. I'm betting they won't as they do not want it out there since it would be an aid to thieves.
Using that a Thief could change the serial number on the stolen motherboard and no evidence so no they won't release it is my guess.
So bottom line it is a HP issue that they need to fix.
