I have an ASUS laptop (ASUS X53S series) and I want to adjust the volume by using the FN key and F10 (mute), F11 (vol down), F12 (vol up).
Also F9 key is not working as well(this is for enabling/disabling the touchpad).
I have seen this question but didn't see any solution.
All the other FN buttons seem to work(changing brightness,turning off display,switching off wifi).
Is there any way to do so?
