Brightness Keys Issue

Hello Archers,

I have a Fujitsu TH700 laptop convertable and when I first turn on the laptop and boot into arch the brightness keys (Fn+F6 and Fn+F7) work fine but after I suspend to ram and power back up the keys no longer do anything.  Volume still works, muting works, touchpad on/off works   its just those two keys that stop working.  I checked xev before and after and before the suspend it shows keycodes but after the suspend the keys produce nothing in xev.

I can post any information that might help just ask for it.

Thanks.

Same problem on my Fujitsu P771 laptop.
Is here any way to fix it?
acpi_listen doesn't help. it display nothing when I press these keys after suspend.
