A:AnswerThe Surface Laptop 4 has a USB-C port. It can be used to charge the laptop if you’ve got a spare USB-C adapter that puts out at least 65 watts, and it also supports video output using an adapter or special cable. But there’s only one USB-C port, and it doesn’t support the Thunderbolt 4 interface.
The MS docking station adds a video port and hdmi for multi monitor support.
A:AnswerMemory is soldered on the motherboard and there are no additional slots. The SSD is upgradable but challenging to install. Also you will void the warranty, so keep the old drive if you need to take it in.
Hope this helps.
