Re: Hotkey

You may have a faulty keyboard driver, go to my computer icon, right click>properties>hardware tab>device manager, then go down list to keyboards, click + sign, right click on your keyboard type and select uninstal. Restart notebook and the keyboard will be installed automatically again and should work, if not, make sure you have the latest drivers. If still not working then there is a hardware fault, but i doubt it as the software is reporting the button is being pressed.

Adjust brightness on laptop

On the Panasonic Toughbook CF30 you can change
the Brightness UP by pressing FN + F2 keys
simultaneously to increase brightness and to decrease it
hold FN and press F1 to lower brightness.
This assumes that you have the HOTKEY driver loaded
first, which enables these function keys.
Good Luck!

How do i make my screen brighter on presario v2000

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+f8 hotkey.

I would like to change the screen brightness on my Tecra 8200 laptop, but can't find HELP on how to do this. Is there a 'hotkey'? Where can I get hotkey descriptions, if they exist?

Normally there's a Function button (Fn) and you can use that in conjunction with the brightness buttons on the keyboard (looks like a sun on most)

Hot Keys

Follow this procedure to enable the special buttons or function keys on the computer or keyboard in the Microsoft® Windows® XP operating system.
  • If software has been installed for use with a third-party keyboard or mouse, uninstall the software to ensure there are no conflicts.
  • On AMD™ or Transmeta™ processor-based computers, the function keys are hardware controlled and not controlled by a hot-key utility.
  • The volume button, brightness key, and disc eject button on some computers will not work if the HotKey Utility application is not running.
  • The Magnify button and the Fn keys will not function properly before the operating system has finished starting.
  • The setting may not be saved if the ESC key is used to close the Fn display. Press the ENTER key or allow the Fn display to close automatically to save the setting.
  1. Click the Start button, then click Run .
  2. In the Run window, next to Open , type MSCONFIG .
  3. Press the ENTER key.
  4. In the System Configuration Utility window, click the Startup tab.
  5. On the Startup tab, under Startup Item , ensure that there is a check in the HKserv checkbox. NOTE: If HKserv is missing, reinstall the HotKey Utility application and the Sony Utilities Library.

You have a blue key that says FN (stands for function) on the bottom left side of your keyboard, next to control and shift. The brightness and dimming hotkey is usually on the arrow keys or up on your f row, f1-f12 and you'll see like a sun and half sun in blue, same as the function key. While holding that function key tap keys you found and it'll brighten and darken. If it doesn't, you may need hotkey software installed, a new LCD (backlight may have failed) or inverter which powers the LCD.
