Hi, I recently upgraded my keyboard from a standard one to a backlit one, i have fitted both ribbon cables correctly and the right way up however the backlit features isnt working, just wondered if anyone knew if maybe a driver was needed?

p.s: the keyboard works

Maybe try using the keyboad commands. I think it is Fn+right arrow key.

Hi Chris-1301,

On studio 1555 the keyboard back light shortcut is Fn and the F6.

Also, I recommend installing quickset on the computer. I have provided a link below for quickset  for keyboard:

http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/studio-15?driverId=DFC1X&osCode=ww1&fileId=27310914273

There are three lighting states that are available in back lit keyboards .Use the Fn and the F6 to toggle between these lighting states.

  1.  Full keyboard/touch pad brightness.
  2.  No lighting
  3.  Half keyboard/touch pad brightness.


Please let me know if you have any other queries.
