Laptop mode lowers LCD brightness when on AC [SOLVED]

I have configured laptop-mode to turn LCD brightness to half of max value when on battery. Everything works fine. When disconnect my laptop from the power source it automatically lowers LCD brightness and when back on AC it comes back to max value. The problem I have is when coming back to AC and only if I leave the laptop unattended for awhile and then move the mouse or touch any button it lowers LCD brightness to what its supposed to be when on battery!!
I don't know whether this is a bug or a misconfigured file. Here is my laptop-mode LCD brightness configuration:

# Commands to execute to set the brightness on your LCD
#
BATT_BRIGHTNESS_COMMAND="echo 12"
LM_AC_BRIGHTNESS_COMMAND="echo 24"
NOLM_AC_BRIGHTNESS_COMMAND="echo 24"
BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video0/brightness"

Any help will be appreciated!!!
Thanks in advanced, José.

Do you have a DE that might also be trying to manage LCD brightness?

OK, seems it was some kind of a bug because after today's full system upgrade I'm not able to reproduce the problem I posted before, Thanks sad clown for your help!!
