   * The **Fn+ESC** should be associated to the **disable touchpad** function (as per the blue label on the key), but it does not work. See this page for a partial workaround: **[[..:linux:sa:touchpad_disable]]**.

+===== Controlling backlight from the command line =====
+You can control the backlight level from the command line (root privileges is required to write):
+<code>
+cat /sys/class/backlight/intel_backlight/brightness
+cat /sys/class/backlight/intel_backlight/max_brightness
+echo 76800  > /sys/class/backlight/intel_backlight/brightness
+</code>
+You can use **xrandr** to simulate brightness control in software (the image is dimmed, but backlight remains actually the same):
+<code>
+xrandr --output eDP-1 --brightness 0.5
+</code>
+===== Power Supply =====
+The power supply of the Teclast F6 is a **12.0 V** rated at **2.0 A** (24.0 W). The coaxial jack has an outer diameter of **3.50 mm**.
