NVME SSD Drive not recognised by BIOS/EUFI

[DuncanRM]

Good Day

I have an interesting problem with my computer, the motherboard does have an NVME, not SATA, an NVME M.2 SSD slot just above the two RAM DIMM slots, I bought a 1TB M.2 NVME PCIe 3.0 SSD and plugged it in correctly, and securely. The drive is formatted correctly, but is not recognized by the computer at all, the BIOS does not see it, the system diagnostics does not see it, the only time the drive is visible to the computer is when I use an NVME to USB adapter and connect the drive to the computer via an external USB port. 

I checked the HP driver and software page for this laptop model, and no updates were pending, I then downloaded all the storage and SSD-related drivers and firmware updates that I could find, but still, the drive is not recognised by the computer when plugged into the M.2 NVME slot. I believe that the computer's firmware is unaware that it even has an M.2 slot in the first place, that HP 'forgot', if I may say, to code into the firmware the PCIe NVME bus protocol.

I did already try go into Disk Management and initialise the drive from there, but, the SSD does not appear anywhere to be initialised, when connected to the M.2 NVME slot, not in File Explorer, not in Disk Manager, not in the EUFI Diagnostics, and not by the BIOS or any Operating System installer, it is only recognised when plugged in through the USB port with an adapter. It's as if the slot is disabled and unavailable. 

Please let me know if there is a solution to this problem, I don't believe HP would install a slot for no reason.

Kind Regards

Hello DuncanRM.

Yes, this is indeed an interesting problem. I hate to break it to you, but HP does all sorts of things for no reason whatsoever -at least not an apparent to us reason. These are the company's systems and they can build them any way they decide to. We have seen slots that haven't been soldered-on, slots that only support SATA m.2, slots with only 2-lanes, you name it -we've seen it.

From your post I gather that you want the NVME to be used as auxiliary storage and not to host the OS. If you give the specifics about your system (HP manufactures many models) and the SSD you're trying to install we might be able to provide more insight on this matter....
