Hi @Atom80 I'll be able to get the serial number and boot NVMe drive details to you tomorrow. I left the laptop in my room as no point bringing it with me to the office. (Currently working in Kazakhstan; +4 hours BST. Not due home until circa 23rd May ) The upgrades I did were as follows: Samsung 970 EVO Polaris 2TB M.2 2280 PCI-e 3.0 x4 NVMe Solid State Drive Kingston HyperX Impact 16GB (1X16GB) DDR4 PC4-21300 2666MHz 260-Pin SODIMM Module Wish I had a set of torx screwdrivers with me. I have an NVMe to USB caddy I could test the drive in. Cheers, John.
