Is it on?

It was a little chilly here in the UK today and as Oliver has a bad cold, I kept him in his pj's and his dressing gown. Isn't he cute? He wanted to sit at the computer and he was tapping away on the keyboard, then grabbed the headphones and put them on (the pc is not on!). I'm not sure if he was hoping that if he put the headphones on, he would hear something or it would turn the computer on.
