The front panel of the S200N only carries a lid latch.

The ASUS S300N, besides the lid latch, has a block of buttons for controlling CD playback on its front panel: stop, play/pause, next and previous. These multimedia buttons can be locked (as I already mentioned above) by pressing the Key Lock button – the CD player indicator will signal about that.

At the rear panels of both sub-notebooks there’s a battery compartment: additional for the ASUS S200N (it already has an integrated battery; if you don’t use the additional battery, you may want to cover this bay with a special gag) and main for the ASUS S300N. The S300N also has a Kensington lock hole here.

At the bottom of both notebooks, you can find round covers of the memory slots (this slot is empty on the ASUS S300N), a battery module and vent holes.
