Running on about 1-2 hours sleep and just got back from work, put my new keyboard in front of me that I received in the post and I didn't plug it in for a while as I was reading more reviews about it, still using my old keyboard. Proceeded to find out if I activated one key first and pressed a few F keys it'd act as a multimedia function to my pleasant surprise. However, to much of my distress, this button did not work as stated, after two minutes of furious button-bashing... I realised it wasn't plugged in.
I need sleep.
