What browser/OS are you on? The LED doesn't blink for me on macOS with Chrome.

Edit: it seems like it's the HDD activity light? It blinks during boot.

I'm using Orion (Webkit-based) on macOS. It was blinking non-stop while just reading the Stickies. I couldn't get past that to do anything else because it was so distracting. It definitely wasn't HDD-related for me. It was constant.
