Here it is:
ACPI: Failed to switch the brightness

but when the backligth is really dim and I press the function key for 
brightness, I get a message saying somethng about wrong value for it. I will 
write it when it happen. ( I don't want to stop/start the laptop until it goes 
wrong. Every forth, fifth time).
Thanks
Thierry
