  Cannot adjust the brightness in a Acer Aspire E1-570-6889.
  The brightness key works and the brightness configuracion in the system configuration allows to adjust the brightness but the display does nothing, it is always at full brightness.
  I may try some things esporadically since it is not my laptop, but I may take a long time to try them :-(.
  Thanks.
