Hello, so my Dell G5 has the standard blue lit keyboard but it is not working at all.  Pressing F10 or fn+F10 does not do anything.  There is no option for keyboard brightness or settings in the Windows Mobility Center.  I checked my BIOS and I think it's up-to-date.  I am fairly new to this so I'm not 100% sure but the version is Dell Inc. 1.4.4.  What other solutions would be recommended to get the keyboard backlight to work again.  Thanks in advance.
