The next two steps show how to install Expansion Cards.

You can charge and use your laptop without Expansion Cards. To charge, plug a USB-C cable directly into any unused Expansion Card slot. The slot's USB-C port is recessed, so not all cables may work.

All official Expansion Cards work fully in all slots, so you can install them however you wish!

You don't need to unlock the latches to install the Expansion Cards—only when you want to remove them.

The Expansion Cards should click in place, and the front edge should be flush with the laptop.
