Cap lock light flickers when on and turns off when on

My caps lock light (green one) flickers on and off while I have caps lock on. I think it just started today because I just noticed the flickering. I don't know if there is a way to fix it or if I should just bring it in to an Apple Store because I still have my limited warranty. I bought this Mac recently around dec/jan so it wouldn't be a wear issue, I hope so. It is a small issue but with the amount of money I paid I don't want any issues. Please let me know if I sound crazy for wanting to bring my concerns to the Apple Store or if there is any solutions to this problem. Thanks!!
