Are you certain that the touchpad wasn't disabled accidentally from the Fn key? There are secondary features assigned to each of the Function (F1-F12) keys, usually in BLUE. On of them is to disable/enable the touchpad (toggle-type function, do it one time to disable, the next to enable). You press and hold the "Fn" key (next to the Windows key at bottom let of keyboard, then press the associated Function Key.

This is due to the special keys in the bios being enabled, enter the bios and enable the function keys if you need those keys more than the special keys (which can also be accessed by holding down the Fn key, lower left).

1 - Function Keys f1 through f122 - Configurable Function key fnDisable fn in the BIOSTo disable, or enable, the function key (fn) in the BIOS, do the following steps.

1. Press the power button to turn on the computer.
2. Press the f10 key to open the BIOS setup window.
3. Use the right-arrow or left-arrow keys to navigate to the System Configuration option.
4. Use the up-arrow or down-arrow keys to navigate to the Action Keys Mode option, and then press the enterkey to display the Enable / Disable menu.
5. Select the desired mode:
   • Disabled : Requires pressing fn key + f1 through f12 to use the action as indicated on the action key.For example, if Disabled , pressing fn + f11 will mute the sound as indicated on the key on this model PC. Alternatively, pressing f11 only will minimize and maximize a web browser if open.The action keys may vary depending on the model of notebook.
   • Enabled : Requires pressing only f1 through f12 to use the action as indicated on the action keys.For example, if Enabled , pressing f11 only will mute the sound as indicated on the key on this model PC. Alternatively, pressing fn + f11 will minimize and maximize a web browser if open.The action keys may vary depending on the model of notebook.
6. Press f10 key to save the selection and restart the computer.

The function key (fn) option can be reset at any time.

Have you tried using the function keys? There is a row of keys at the top labeled F1 though F12, they also have symbols. Find the one that looks like one of these, press and hold the function enable key that is like at the bottom of your keyboard and then select the button you found in the top row.

Hi
To fix an unresponsive touchpad on your laptop/desktop XP Home, XPPro:
Reactivate it by using the Function key on the keyboard and the Fn key.

This process is different for each computer manufacturer.
If unsure which Function key enables and disables the touchpad, try each one at a time and then
attempt to use the touchpad after each one.

A...Locate the "Fn" key of the laptop keyboard.
The "Fn" key has different colored text or the key is a different color.
B...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.
C...Press both the "Fn" and touchpad Function key at the same time 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.
Note: Mac computers use "F2" to enable and disable the touchpad.
Please take time to rate me

Hi slimmerkitty...

I am unable to find a photo of your laptop's keyboard, so I cannot be certain which function key will enable your wireless adapter.

However, most laptops are very similar, so this solution should work for your problem.

1) Locate the secondary function key (probably labeled "FN") on your keyboard.
2) Locate the key which controls your wireless adapter as a secondary function. It will have the following image on the key: http://cdnsupport.gateway.com/s/Mobile/2007/Phantom/WirelessIcon.gif
3) While holding the FN key, press the wireless key
4) Your wireless adapter is now enabled. If you are still having wireless issues, the problem was not that the hardware wireless adapter was disabled.

pressing the fn key simultaneously press the keys marked with othr colours like orange \ or blue ..... these keys wil function whn the fn key is pressed...!!!
