Thanks for the serial number, but it's usually safer not to publicly provide serial numbers if you have any concerns about that.
Anyway, if you were interested, showing this serial number is using the GL552VX motherboard that only supports SATA M.2 SSDs, so don't expect you can get any NVME M.2 SSDs working for this notebook. Thanks.
For those that are wondering it appears we can sell the GL552VX with 6th gen. Intel cpu or 7th gen. Intel cpu which is still considered to be the GL552VX model, but actually using a different GL552VXK motherboard and bios.
Anyway, the GL552VX with 6th gen. Intel cpu will use different motherboards to support SATA M.2 SSDs or PCIe M.2 SSDs, so the same motherboard cannot support both types of M.2 SSDs and you need to confirm the motherboard specs to know which will work.
Apparently the GL552VX motherboard with 7th gen. Intel cpu (which is really the GL552VXK motherboard using the GL552VXK bios) can support both SATA3 M.2 SSDs and PCIe M.2 SSDs with the same motherboard, so we need to check the motherboard specs carefully to know what will be supported and checking the bios model may provide some clues. Thanks.
