This goes with seeking professional help. Check your warranty. When you buy a computer, the vendor warranty covers a certain period after purchase. This can be accomplished by going to the vendor website and checking using your machine type/ model/ serial number or service tag. If it is within warranty submit the claim. If it is not within warranty, look into reactivating or extending the warranty. Going the warranty route can save you money on parts, labor and frustration. It can also provide a rote for further or future repairs if needed.

The points that are mentioned above make sense, but something like a keyboard's backlight does not need professional help initially unless the problem is constant. Try a simple hack which I do when problems like this occur. Simply close your laptop and open it again. Sometimes the switch that tells the computer your lid is closed can get stuck. Closing and opening the lid can sometimes fix this.
