The W840SU is a device by the taiwanese OEM manufacturer Clevo. It is sold as Schenker S403, Tuxedo Book UC1402 and Nexoc B401. A touch version exists as W840SU-T or UT1402. The hardware is configurable and includes an Intel Haswell Core i3/i5/i7, Intel HD 4400 graphics, a 7 mm harddrive, a mSATA device (storage, 3g/LTE modem) and a HDMI output.


Installing Arch Linux is straightforward and most of the hardware works out of the box.

Airplane Mode

Use xbindkeys to map the key 255 (NoSymbol) to some script that disables wifi and bluetooth and enables the airplane mode LED.

$ cat ~/.xbindkeysrc
"sudo /home/user/bin/"
   m:0x0 + c:255

Enable the LED with:

# echo 1 > /sys/class/leds/tuxedo::airplane/brightness

You can automate this by installing the AUR package clevo-airplane-modeAUR[broken link: package not found].


The webcam needs to be activated by pressing FN+F10, otherwise you do not see the device.

Sound mostly works out of the box. Using PulseAudio simplyfies configuration, switching outputs is possible.


The volume control for the microphone is mislabeled and reads Digital in ALSA.


The touchpad works out of the box with the synaptics driver. All current features are supported including two finger scroll, two- and three finger click and optional mouse buttons for the edges. Use synclient for configuration. Four finger recognition and three finger swipe gestures do not seem to work, though.
