It is possible to upgrade graphic card in any clevo laptop that has MXM slot? As I understand it should looks like upgrading graphic in a PC - it does not matter what CPU/bios/board you have, if you have PCIE slot you can put inside newest graphic card and it will work (maybe not in a full speed mode, but it will work). Are there some whitelists/bioses/CPU restriction in clevo laptops? I understand that heatsinks should also be changed when adding a new GPU, but EVERY MXM slot GPU will work? Does clevo laptops have CPU nests (CPU is not soldered/glued)? Desktop CPU are welcome but mobile are also accepted.
