The connector from the main board, and you also have to undo the four Phillips head screws that are fixing the unit to the base. The capacity is enough for 8 hours and 20 minutes of web browsing, or 6 hours and 40 minutes of video playback. It lasts for 12 hours and 30 minutes of web browsing, or 8 hours and 20 minutes of video playback. Considering the modest capacity and the high processor frequencies under any kind of load, this result is very good. The memory here is soldered, but the maximum amount of 32GB of LPDDR5. 4800 MHz RAM in dual channel mode seems future-proof. In terms of storage, there are two M.2 slots. The one on the left is compatible with Gen4 SSDs, while the other one is for Gen3 NVMEs. The cooling solution looks potent. It has two fans, two heat pipes, a couple of heat sinks, and a massive heat spreader.
