Brightness settings stop working after hibernation or sleep Windows 7

Hey guys. So i have an Asus ROG G751JY laptop. So when i put it to sleep or hibernate, the screen brightness controls (Fn+F5 and F6) dont work. The animation pops up on the screen but it doesnt do anything. Hibernation doesnt resume etheir but thats for another thread. Any ideas here?

Hello Nikak mate one of my machines is a G750JM ROG and I find most little irritations like that are fixed with a simple run of these
SFC /SCANNOW Command - System File Checker
Disk Check < if necessary include the /f and /r in the command line as per Option2
Run these in safe mode and the sfc often best run for two to three runs - you can leave out the /r switch if you think it not necessary.

Edit Forgot try updating the NVidia driver too

Ok first, my Nvidia driver is using the most current driver available for the 980M, second, sfc wont take those switches.

"windows resource protection has found corrupt files but was unable to fix some of them." "Details in cbs log...."

i ran it like 6 times and it says the same thing every time.

Windows 7 Does not reload after hibernation/sleep
This happens very frequently. It happens on and off. I am running Windows 7 professional on Dell Inspiron E1505 and when my computer goes into hibernation ( it doesn't matter if it's on battery or plugged in), sometimes I can reload the computer physically. Sometimes or most times, it shows a black...

Windows enters standby/hibernation even with power settings adjusted.
Even with my power settings adjusted, my computer will still periodically go into sleep every half an hour to an hour or so without attendance. Its annoying mainly because I play xbox live, which is bridged through my pc, and I get disconnected because of this. Any reasons why it could be doing...
