Alienware 17 Does Not Turn Off Properly

Hi there,

So ever since last week, sometimes, not all the times, my laptop does not turn off properly. The screen goes off, the fans go off, but the light on the power button stays on. And when I try to turn my laptop back on again, I press the ON button and nothing happens. So I have to press and hold the power button to shut it off, then press it again to turn it on. Other than this issue, it works fine as far as I can tell. I did some research online and looks like it might be a BIOS issue, but I am not sure.

Any idea what would cause this?
