Anybody knows if it's possible replace the laptop's SSD with another M.2 but pcie? I have read in some forum on internet that's possible but i'm not sure because i bought a Samsung SM951 e i tried to mount but the notebook does not see it!!!!
The laptop's M.2 connector is it compatible with pcie? Can i replace my SSD with one pcie?
I updated BIOS to rev F.25 but nothing. Is there some BIOS configuration to do so that the notebook can see the pcie SSDs?
Thanks for replies and sorry for my bad english

Can you identify where you tried to put the mSSD by reference to the Manual here:
See p. 28.
It uses M.2 SATA drives and if the drive you installed is a PCIe type it will not be recognized. AHCI type drives only as far as I can see. I know only the very most recent desktop motherboards will boot from a pcie M.2 mSSD.

probably the manual is outdated because after various tests the computer has recognized the SSD one time
after I have disabled the TPM (trusted platform) in the BIOS.
Anyway i read in this and in other forums that someone has substituted the original SSD with one pcie with no problems.
In this moment i can't make other tests because the SSD is not mine and i returned to the owner.

M2 SSDs depending on the controller in the SSD can run either off the PCIe bus without an existing system board controller or will use the Intel SATA controller requires the PC be in RAID mode. Most HP consumer level PCs are not provisioned in the BIOS for PICe boot devices but that doesn't necessarily mean that it will not work.
Booting via PCIe with some M2 SSDs requires UEFI mode which means using Windows 8.1 or Windows 10 to ensure that you have the proper drivers in the installation media. This would be one possible way around the BIOS restricting boot device paths. If the w8/w10 installation media was booted in UEFI mode and discovers the M2 SSD via the Custom installation process the you have a chance to make the PCIe device boot. The boot menu selection after a successful installation would then indicate the presence of the Window boot loader maybe two if your original boot device booted in UEFI mode. I recommend that you unplug the main boot drive when attempting to install another OS.
There was one post on the destop forum some time back where a SATA to PCIe adapter was used to load Windows to a PCIe device.
I believe this was done in UEFI mode but I could be wrong.
Checking the the M2 SATA manufacturer might give you some suggestions. You might find the below message interesting.

i have just replaced the SSD that come with the laptop with a samsung SM951 pcie.
The old SSD:
The new (samsung sm951):
I can confirm that the laptop's M.2 connector supports pcie

I was told by HP the m.2 of Spectre X360 would only work with PCIe AHCI, not with PCIe 3.0 x4 NVMe of the 950 Pro.
What BIOS version are you on?
Can you confirm the generated heat (5W average power consumption) combined with the limited cooling capacity is not causing throttling all the time?
