Thank you for posting in the Intel® communities.
I understand that you would like to know if the Intel® Optane™ Memory works with your laptop.
I'd like to let you know that for specific laptop models compatibilities with the Intel® Optane™ Memory, it is recommendable to contact the manufacturer and confirm with them the support of the module. Even though you have an M.2 slot available, it doesn't mean the Intel® Optane™ Memory will work. There are other details like the processor, the motherboard's chipset or BIOS version that will be required for the module to work properly. This information is sometimes available when dealing with Desktop computers, but when dealing with laptops, this information is usually not available. That's why we recommend to contact the manufacturer.
However, after doing some research about this laptop model, I found a thread in the Lenovo* site where another user tried to install the Intel® Optane™ Memory with no success. Apparently he got an unsupported BIOS error which means the BIOS doesn't support the module. Based on that information, I'd say that your laptop is not compatible with the Intel® Optane™ Memory. You can check in the following link what this user posted in the Lenovo* site: https://forums.lenovo.com/t5/Lenovo-IdeaPad-1xx-3xx-5xx-7xx/Ideapad-320S-14lkb-80x4-installation-of-...
I hope you find this information useful. If there is anything else I can help you with, let me know.
Have a nice day.
