1. Remove the bottom plate

To take this laptop apart, you need to undo 10 Phillips-head screws. After that, pry the bottom panel with a plastic tool and remove it from the chassis. Keep in mind that you may need to apply more force in the area around the side vents.

2. Battery

Inside, we see a reasonably big 80Wh battery pack. Should you ever need to remove it, you can do so by unscrewing all 6 Phillips-head screws. Don’t forget to unplug the battery connector.

3. Мemory and storage

In terms of upgrade options, there are two SODIMM slots for memory expansion hidden beneath a metal shroud. They support a maximum of 64GB in total and work in dual-channel mode. Additionally, you get two M.2 slots, one of which can hold PCIe Gen 4 drives. To access all of the storage ports, you need to remove the metal cooling plates.

4. Cooling system

Cooling-wise, there are three rather big heat pipes. They are split between the CPU and the GPU and connect to a total of four heat sinks. Moreover, Lenovo has installed two heat spreaders, that manage the temperatures of the VRMs and the graphics memory.
