So on my keyboard the function keys also have the volume options, video playback options, and a battery meter menu option on top of them. Recently, if I were to click the increase volume icon, the image for the volume doesn't show up. Same thing for the screen light dimming, and more annoyingly, the battery meter menu. The volume and dimming options still work, however the menu for the battery options does not come up. I used to be able to disable charging to my battery from that menu, and no matter how many times i press it, it does absolutely nothing. Any solutions? Drivers that need to be reinstalled?
