Hi Tom,
After Googling your issue, it would seem that you do not have a Wireless
switch to physically turn off your Wi-Fi signal.
In face, some posts I saw said that your computer comes with a Wi-Fi dongle,
so you may want to look into that.
In terms of a software switch, if your laptop does have wireless
capabilities, then the key combination is FN+F2.
On most laptops, the FN key is the first key to the right of the left
control key.
Hope this helps.
Scorpio
