Unable to change the Display Brightness

In Compaq6720s, I am unable to change the display brightness.

If I click "Fn+F9" I could confirm the mute-mode toggling from the Control-Panel Sounds-and-Audio Devices Screen. Similary if I adjust brightness with Fn+F7, Fn+F8, where I could confirm the adjustment happening?

I need an explanation as to the secondary function of the keys on my NB305. Mainly the top row of 'F' keys, but the remainder of the keyboard as well. What do all these little symbols on the keys mean?


F1 through F12 are called function keys because they execute programmed functions when pressed. Used in combination with the Fn key, keys marked with icons execute specific functions on the computer. The function executed by individual keys depends on the software you are using.





1. Sound Mute: Pressing Fn + ESC in a windows environment turns sound on or off. Press Fn + Enter to simulate Enter or the enhanced keyboard's numeric keypad. 2. Instant security: Press Fn + F1 to blank the screen to prevent others from accessing your data. To restore the screen and original setting, press any key or press the Touch Pad. 3. Power save mode: Pressing Fn + F2 changes the power save mode. 4. Standby: When you press Fn + F3, the computer enters Standby. 5. Hibernation: When you press Fn + F4, the computer enters Hibernation. 6. Display selection: Press Fn + F5 to change the active display device. Hold down Fn and press F5 again to change the device. 7. Internal LCD screen Brightness: Pressing Fn + F6 decreases the display brightness in decrements. 8. Internal LCD screen Brightness: Pressing Fn + F7 increases the display brightness in increments. 9. Wireless setting: If your computer has both Bluetooth and Wireless LAN functions, you can press Fn + F8 to select which type of wireless communication you want to use. 10. Touch Pad: Pressing Fn + F9 in a windows environment enables or disables the Touch Pad function. 11. Press Fn + F10 or Fn + F11 to access the integrated keypad. When activated, the keys with gray markings on the bottom edge become numeric keypad keys (Fn + F11) or cursor control keys (Fn + F10). The power on default for both settings is off. Press Fn + F12 (ScrLock) to lock the cursor on a specific line. The power on default is off. 12. TOSHIBA Zooming Utility (reduce): To reduce the icon size on the desktop or the application window, press the 1 key while holding down the Fn key. (13. TOSHIBA Zooming Utility (enlarge): To enlarge the icon size on the desktop or the application window, press the 2 key while holding down the Fn key.

Another way to adjust the screen brightness is to hold down the Functin key (blue, Fn) and then repeatedly press the up or down arrows (which also show the symbol for screen brightness on the keys in blue.)
