Asus laptop, fn keys - Dell Latitude D600 Notebook

I have an ASUS laptop and I use fn f11 for volume down, fn f12 for volume up, and fn f10 for mute.
fn is the function key and is found on the left bottom of the keyboard between the ctrl and windows keys.

Connecting an External Monitor or Data Projector
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 ASUS and Dell = Fn + F8

Step 1:
Touchpad Not Working in Laptop b> Locate the "Fn" key in the lower right or left corner of the laptop keyboard. The "Fn" key typically has different colored text on it or the key itself is a different color. Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop. The key typically has an icon that resembles a touchpad with a finger touching it or a touchpad with a diagonal line through it. Press both the "Fn" and touchpad Function key simultaneously to reactive the touchpad on your laptop. Move your finger along the touchpad to verify that it works. Press the combination at any time to disable the touchpad again.

Hook a external keyboard to the laptop, if all functions checkout. The keyboard in the laptop will need to be replaced..

ASUS A42J IS THE WORST LAPTOP I HAVE USED EVER!!!!

On the bottom-left of the keyboard is the BLUE-coloured 'FN' key. Hold the FN key down (just as you would hold hold the SHIFT key) and touch one of the other blue-labelled keys, and release the FN key.

thats a good one for people with long fingers!

Try holding fn key and hitting scroll lock or num lock to see if that does it. sounds like you have somehow locked your fn key on.

Try the Fn key and F11 or F12 - that should turn up/down the volume on your Acer, depending on the model

Hope this helps - good luck!
