The battery inside has a capacity of 90.6Wh. It lasts for about 7 hours of either Web browsing or video playback. Furthermore, it is pretty easy to remove. Just unplug the connector, and undo two Phillips-head screws.

3. Memory and storage

To access the memory, you have to take out the metal bracket. It is held in place by one Phillips-head screw and a couple of clips. Once you remove it, you will have access to two RAM SODIMM slots, which work with DDR5 modules. As for the storage, you get two M.2 PCIe x4 slots, both of which can fit Gen 4 drives.

4. Cooling system

In terms of cooling, you get two heat pipes shared between the CPU and the GPU. The processor gets one more, while the GPU is treated to two additional heat pipes. Moreover, the graphics memory and the VRMs have a metal heat spreader, while two fans blow the heat away from the machine.
