asus laptop disabling mouse pad

The Issue:

If you use an Asus laptop for work, you have been frustrated at least one time with the enormous multi-touch and multi-featured touch pad it features after tripping on it with your hand while typing and ended up sending some data to the wrong place (or application I should say).  

You probably already have a secondary "decent" mouse plugged into it but you still having occasional unexpected clicks here and there while typing. 
Here is the solution with 2 different approaches:

for THE DAILY ROUTINE:

Most Asus laptops come with a function key to disable the touchpad; if so,
STEP 1 (and only) Press and hold the FN key and then press the F3 or F9 key depending on the model.

FOR THE LONG TERM:

If your laptop is normally fixed to your desk and you always use a secondary mouse, you may want to deactivate the touchpad completely: (assuming you have administrator rights, otherwise ask your IT administrator)
1. Click Start and then Control Panel
2. Double click on "mouse" and then click the Hardware tab
3. Locate the Mouse setting and change the status to "disabled"
*. If you want to revert this setting, follow same steps but in step 3 change the status to "enabled"
