1. Remove the bottom plate

To access this notebook’s internals, you need to remove the two rubber feet. Then, undo all 7 Phillips-head screws you see, and pry the bottom panel with a plastic tool. To do the last thing, you need to slightly open the lid of the laptop.

2. Battery

This device is equipped with a rather small 41Wh battery pack. It lasts for less than 7 hours of Web browsing, or about 5 hours and 30 minutes of video playback. You can remove it by undoing 4 Phillips-head screws.

3. Memory and storage

Thankfully, you see two SODIMM slots, which work in dual-channel mode, and support up to 64GB of DDR4 RAM. Storage-wise, there is one M.2 PCIe x4 slot, which only supports Gen 3 drives. In addition, there is a 2.5-inch SATA drive bay without the necessary mounting accessories.

4. Cooling system

The cooling comprises a single chonky heat pipe, a long heat sink, and a fan. Additionally, the graphics memory and the VRMs have heat spreaders mounted on top of them.
