Function key doesn't work


Hello, if the key is broken (Won't work at all) there is no way to fix it unless you replace the keyboard. You can however look for the: ATK / KB Filter Utility for Asus machines and that will give you access to some of the hotkey functions without having to use the fn key itself. You can find that here: http://support.asus.com/Download.aspx?SLanguage=en&m=ATK_package&os=30

Unfortunately the fn key is not part of standard bios's as far as I know for most machines so you can't remap it to another key. You might be able to switch the [fn] function around though so you don't have to press the [fn] key to use the hotkeys.

It will look something like this: http://cdn4.thetechjournal.net/wp-content/uploads/2012/10/action-keys-bios-as7d889we79we7r9ew5rty321u32.jpg

To get there hold [F2] whilst powering on the machine and you should see something similar to that pic. Once done save and exit.

Please bare in mind that if you do this you will only be able to us the hotkeys in windows unless it's a keyboard specific command, e.g [Ctrl] + [Shift] + [F4].

Hope that helps

Fn not working


Hi Dimitar,
We often hear users telling us that they not able to use Fn keys such as the fn for wireless, sleep, etc.
In fact, you need to install power management software and drivers whereby it has hotkey driver included in it. Hotkey driver is the key to make sure the Fn keys work.

Briefly press the fn key, and then briefly press the second key of the hotkey command.
- or -
Press and hold down the fn key, briefly press the second key of the hotkey command, and then
release both keys at the same time.

Trying using the "numlock" key it should undo the Fn hot keys. If your notebook is in hibernate state, using the power-up switch on the notebook will activate you notebook. This will ask you for a password, if you have been using one to logon to you notebook. The FN+F4 or F5 will toggle between a blank screen and a display.

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.
