I undestand some of you are reporting that after ugprading the video driver the adjustment brightness keys are not working properly for the E420s / E420 / E520.
Appreciate if you could let me know here. Also please try uninstalling, power manager, power management driver and hotkeys, reboot then install them back.
If problem persist, just post here or hit the "Me Too" button.
Solved! Go to Solution.

I am sorry for the lame question, but where exactly do i find the hotkey patch to uninstall it.
What i uninstalled, was the Interface driver?! I think that is what controlls the hotkeys or am i wrong.
Uninstalled every thing, installed again. Screen brightness can still NOT be adjusted with the F7 & F8 keys.
Only from the Power Options in Control Panel.

I experience the same issue as well.
If you release an updated driver, is it possible to incorporate the current ATI driver version?

Will there be any solution for this ? The problem exists, when system uses Radeon graphics only.

Nope, new BIOS does nothing.
But if I put brightess to maximum and press F8 (increase brightness) it shows me that brightness is full (15).
And same thing with minimum brighness pressing F7. (Not sure if that was there in the other BIOS)
I still can't change it though.
