What's the most simple way of going about this? I've looked at various hacks on Google, but they seem quite complex and involve using 3rd party software etc. Why would I want to do this? I occasionally move room to room with my laptop, and when I do so, I have to be careful how I carry the laptop since the lid is open. Was much easier to do this when I could just close the lid, like on my old Windows laptop. Ta.
