My friend has a Lifebook AH550 running Windows 7 Home 64 bit. I recently cleaned up her computer, removing a bunch of spy ware and bloat that had gotten installed over time.
Later I noticed that the Brightness Controls on the keyboard were no longer working. When you Press Fn + F6/F7, the brightness settings would be displayed on the screen but the green bar would not go up or down and the brightness of the screen didn't change at all. I found the Lifebook AH550 software page (http://support.fujitsupc.com/CS/Portal/supportsearch.do) and reinstalled several items including the Hotkey utility and the Intel Video Driver (the lifebook uses an Intel integrated video card, not the ATI/AMD card).
Does anyone have any recommendations on how to fix this problem? Is there a certain driver that I need to absolutely make sure I install to fix this problem?
FYI I also have installed ALL Windows 7 updates.
