1. Remove the bottom plate

This notebook’s bottom panel is held in place by 8 Phillips-head screws. Two of them are captive and lift the panel gently, so you can start the prying process from there.

2. Battery

Our unit is equipped with the smaller of two battery options. It has a capacity of 41Wh and lasts for about 8 hours of Web browsing, or 6 hours and 30 minutes of video playback. To take it away, unplug the SATA cable, and the battery connector, and undo all three Phillips-head screws keeping it attached to the chassis.

Two SODIMM slots work in dual-channel mode. Storage-wise, you get one M.2 PCIe x4 slot, which supports Gen 4 drives. Also, there is a 2.5-inch SATA drive bay, which is only available with the smaller battery option.

4. Cooling system

Which now comes with a 120Hz refr[...]
