I can control the backlight of my netbook by means of the "/sys/class/
backlight/intel_backlight/brightness" key.

So:

echo 500 > /sys/class/backlight/intel_backlight/brightness

Will darken the screen and keep it so until I change it again by using 
the function keys or manually editing its value. 

Just note the name of the key can be different in your Acer netbook.
