Edge LED
The Edge LED (labelled
LED
, see position
(8)
in section
page 15]) is a user-programmable yellow/green Duo LED.
It can be controlled via Linux in the directories:
/sys/class/leds/edge_green/brightness
/sys/class/leds/edge_yellow/brightness
For example, you can switch the LED to steady green by entering the
following command in the terminal:
sudo sh -c "echo '1' >> /sys/class/leds/edge_green/brightness"
The green light can be switched off again by entering:
sudo sh -c "echo '0' >> /sys/class/leds/edge_green/brightness"
