i saw Console.app but not found 'failed to load'
I'm not sure what you're saying. You need to look in system.log for debug messages related to ACPIBrightness and see if you can tell what is happening (or not happening).
and i edited dsdt. but max bright fail...
I can't help any further. It is now up to you to do some debugging... Good luck.
Note: Not all DSDT brightness methods work (for example, the ProBook DSDT tries to call back into Windows via WMI and fails).
