1. Remove the bottom plate
This machine’s bottom panel is held in place by 9 captive Phillips-head screws. After you undo them, you need to pry the bottom panel. We found it the easiest to start from the back.
2. Battery
Inside, we found a 64Wh battery. By the way, some options include a larger 97Wh unit, which takes the space dedicated for an optional 2.5-inch SATA drive. To take the battery out, you need to unplug the connector. Then, undo all three Phillips-head screws, and remove the unit from the chassis.
3. Memory and storage
Memory-wise, there are two SODIMM slots. They can fit up to 64GB of DDR4 RAM. As for the storage, besides the optional 2.5-inch slot, there are two M.2 PCIe x4 slots. One of them supports Gen 4 drives as well.
4. Cooling system
Finally, there is the cooling. It comprises two very long heat pipes, which lead to a side-mounted heat sink. The heat is then blown away with a single fan, which has a pretty thick profile.
