Hi everyone,
I'm very happy with this laptop but there is an empty M.2 slot waiting to be filled. The connector seems to offer the right pins for a PCIe x4 SSD like the SM951 but someone at Notebookreview reported that this particular model dosent work. Is it possible that NVME is the problem and other PCIe SSDs should work? Could a BIOS mod help (like inserting BIOS modules)? Can I somehow determine whether the hardware supports PCIe x4 in this M.2 port?
I tried reading the PCIe configuration of the CPU with Linux, but can't interpret the result...

Maybe someone with a little bit more experience knows what that means.
