if so, try this

Here is the solution I found on another website...

(0) Save all your open documents and stuff and close their respective programs

(1) Navigate to the following directory: C:\Program Files (x86)\Toshiba\System Setting

(2) Double-click on the "System Settings.exe"

(3) Scroll down in the left menu until you find "keyboard"

(4) Click on the "keyboard" menu option and change the default "special function mode" to "normal f1-f12"

(5) Click the "apply" button and allow your computer to restart.

All done!!
