Function keys in my Toshiba Satellite P55W-C5204 are not working, after I made a factory reset (but without deleting my files) Before that I could use all of them, combined with FN. Now, the keyboard does not lighten up, when I press FN+Z, or I cannot mute my laptop by pressing F11 etc. After the reset I got a file with names of all deleted applications. One of them is probably the one that causes all the trouble. It's TOSHIBA Function Key versin 1.1.16.6401. The newest version I found on Toshiba support pages is 1.1.15. Is there any way I could get those functions back? I cannot find ver. 1.1.16... anywhere. Help me, please
