I have exactly the same laptop model. If I remember correctly acpiwmi is 
not enabled for GENERIC kernel. If I compile a kernel with it I can 
control volume keys and keyboard backlight keys.
For me a bigger problem is GPU not initializing correctly from time to 
time. I see in your dmesg you have the same problem.
