Hi there everyone,

Can anybody please help me,I set my keyboard backlight to dim but everytime I turn on my laptop again after shutting it down the backlight is at full brightness.I know this doesnt sound like that big of an issue but its bothering me alot.I have windows 10 and updated Dell software that comes with the computer.

Any help will be greatly appreciated.
