1. Remove the bottom plate

There is a total of 11 Phillips-head screws you need to undo to get inside this notebook. The one in the bottom right corner is captive, and will gently pop the bottom panel so you can start the prying process from there.

2. Battery

Inside, you will find a 76Wh battery pack. It lasts for 9 hours and 30 minutes of Web browsing, or 8 hours and 30 minutes of video playback. To take it out, unplug the connector from the motherboard, and undo all four Phillips-head screws holding it in place.

3. Memory and storage

Memory-wise, you get 8GB soldered to the motherboard, as well as one SODIMM slot for DDR5 RAM sticks. The maximum capacity here is 24GB. In terms of storage, there is one M.2 PCIe x4 slot, which works with Gen 4 SSDs too. After you take the SSD out, you can proceed to remove the battery.

4. Cooling system

You will find the biggest improvement from last year in the cooling section. Now, it sports a vapor chamber, which will dissipate the heat from the CPU, GPU, VRMs, and graphics memory. It is being helped by two heat pipes and two fans.
