Thanks for the response stevea , I tried it and i got :
[arif@MyLapZ560 ~]$ sudo modprobe thinkpad_acpi
[sudo] password for arif:
arif is not in the sudoers file. This incident will be reported.
[arif@MyLapZ560 ~]$ su
[root@MyLapZ560 arif]# modprobe thinkpad_acpi
FATAL: Error inserting thinkpad_acpi (/lib/modules/3.3.5-2.fc16.x86_64/kernel/drivers/platform/x86/thinkpad_acpi.ko): No such device
(in my laptop brightness keys are Fn + up and Fn + down).
I tried to change the brightness even it thrown an error , but it did nothing.
