A 14-inch laptop with that much upgradability is rare these days.
1. Remove the bottom plate
To get inside of this laptop, you have to undo 7 Phillips-head screws. The two in the back corners remain attached to the panel and gently lift it so that you can start the prying process from there.
As far as the power away from the plug goes, Dell provides the machine with a 53Wh unit.
3. Memory and storage
Interestingly, this is probably the best-equipped thin and light notebook when it comes to upgradability. There are two RAM SODIMM slots that work in dual-channel, and support up to 32GB of DDR4 memory in total. Also, the memory works at 3200 MHz. And not only that, but there are two M.2 PCIe x4 slots for extremely fast storage options. One is placed above the battery, and one to its right side.
4. Cooling system
Above the CPU, you can see a metal bracket, which makes direct contact with the 45-degree mounted heat pipe. Then, the thick heat pipe drives the heat to the heat spreader, which then dissipates it, thanks to the fan.
