keyboard My dell laptop keyboard backlight wont turn on

[Shammikit]

so i have the dell inspiron 15 5558 core i3 laptop.I firstly didnt know this keyboard was backlit, after finding it out from some websites i found it.how ever i dont see a way to turn it on.some say to check mobility center but it doesnt refer to anything about keyboard backlight. i checked BIOS settings and the backlit keyboard was enabled and set to full brightness. i guessing a driver is missing.is there a driver to get this running.my os is windows 8.1

the BIOS says its fn + f10 key but this does not work.

the driver to the keyboard according to device manager is taken as standard ps/2 keyboard
