I have a problem. I just got back my computer from a repair shop, and all they could do was reload it back to factory settings. Anyway, now I have problems. First i used to have bars that pop up when I adjust the sound or brightness, and had a pop up saying whether CAPS is active or not. Now none of those happen. Also, my hotkey to disable my touchpad(which I need to do) won't work. Anyone know how to help? PS i have a dell inspiron.
