Question

I was using my computer all day fine, went to work for a couple hours, and come home to my computer not turning on. The adapter is plugged into the wall, I've tried several outlets, and nothing happens when I turn it on. Even with it plugged in, no lights are showing that it's plugged in, like it usually does. I need help please!!
