When the notebook is operating in Windows desktop, hold the function (fn ) key down while pressing the f7 and f8 keys to increase or decrease the brightness of the display and more details visit the below link
Decrease Brightness (fn+f7) The fn+f7 hotkey decreases the brightness of the notebook screen. The longer you hold down the fn+f7 hotkey, the more the screen dims. Decreasing screen brightness conserves power.» To increase screen brightness, press the fn+f8hotkey.
Increase Brightness (fn+f8)The fn+f8 hotkey increases the brightness of the notebook screen. The longer you hold down the fn+f8 hotkey, the more the screen brightens.» To decrease screen brightness, press the fn+f7hotkey.
Compaq says to DECREASE the screen brightness for your specific model, use the fn key in combination with the F7 key (basically, hold down the fn key and press and release the F7 key). That most likely means that the Function key to INCREASE the screen brightness is usually on one side or the other (F6 or F8). Also, look for what the other User suggested; the function key should have a picture of a sun or sunburst. Hope this helps.
