How does the stand charge the computer?
If the stand doesn't come with an AC charger, how does it charge the computer? I assume you use the AC charger that comes with the computer? What's the purpose of the magnetic pogo pin connector (to hold the computer in place on the stand)?
Yes, the AC adapter that comes with the computer can plug into the computer or into the screen. Plugging it into the stand removes the need to plug and unplug the computer if taking it to another room for use. Magnetic pins make it easy to always get the computer in the right place in the stand.
