Hi @redill
The laptop supports up to a maximum of 32GB DDR4-3200 (PC4-25600) sodimm memory over 2 slots i.e. 2 x 16GB modules.
There is one M.2 PCIe 4.0 socket which takes an M.2 2280 NVMe SSD (up to 2TB) and you can also replace the existing sata HDD with a 2.5" 7mm sata SSD as well (up to 4TB). If you decide to upgrade the HDD to an SSD ensure that the SSD comes with a 9.5mm spacer, which is placed under the SSD so that it raises it to the correct height to align with the sata connector on the board.
Here's the maintenance and service guide for the laptop series that may help.
