1. Remove the bottom plate

This laptop’s bottom panel is held in place by 8 captive Phillips-head screws. After you undo them, the two on the back will lift the backside of the panel by a couple of millimeters. This will allow you to easily start the prying process.


2. Battery

Our unit was equipped with the larger 54Wh battery pack. To take the battery out of the machine, remove its connector from the motherboard. Undo all 4 Phillips-head screws, and lift it away.

Here, you will see two SODIMM slots. According to Dell, they support up to 32GB of DDR4 RAM in total and work in dual-channel mode. Storage-wise, there is only one M.2 PCIe x4 slot.
