Whether NVMe slot available in motherboard

[okayalexa]

I want to upgrade/add m.2 nvme ssd drive on my laptop, is it compatible on HP 14 cm0123au? Is the slot compatible?

According to the HP Maintenance & Service guide, NVMe, PCIe, SATA3 and NVMe M.2 SSD drives are compatible.

Before pulling the trigger on a purchase, I would open the notebook to take a look and verify that the M.2 slot is present.

I just took a look at the Crucial Memory website.

According to them, there are only SATA3 2.5" SSD drives that are compatible. I would believe I Crucial website.

 Hello thanks for reply,

Using software,  I check some configuration of laptop, it says something about PCI express 3.0 x4, does that mean it will support NVMe? Or I'm getting it wrong.

 PCI express 3.0 x4 is just an indicator of the number of lanes that the PCIe Express slot uses.

I was poking around and found a thread where one of our member HP Experts was asked the very same question.  It does appear that the Maintenance & Service guide is giving conflicting information. 

Crucial Memory states that they guarantee SATA3 SSD as being compatible, not NVMe. I would tend to believe what Crucial memory states over the Maintenance & service Guide. They test what works.
