    Yes, some times it might. But still if the keyboard backlight is not working than the keyboard might be faulty. or try to install the keyboard drivers and check.

    I bought it online, and it got delivered today only. And it's not working from the time it is delivered.

    Try the below simple step and check
    power drain: Just check the back of the unit, you can find a pin hole , unplug the charger and turn off the unit. 
    now put a paper clip in the small pin hole and press and hold it for 30 sec.

    BIOS default: After power drain is done, power on the unit, but as soon as you power on the unit keep pressing 
    the F2 key so that it take you to BIOS page. Press F9 and press Enter than press F10 and press Enter. the unit 
    will restart.

    I was messing with my computer's registry to tweak my UI; and a few things went 'off'.

    I ran an SFC scan to restore my 'Services'. This ended up disabling my keyboard back-light.

    Did a BIOS 'Reset to Default settings', 'Save & Restart', and that got the keyboard back-light working again. I hope this helps.
