Change What Windows Does When You Close Your Laptops Lid

By default, most laptops automatically go into sleep mode when you close the lid. This is usually great, as most of us shut our laptops, throw them into our bags, and then expect them to be running in an instant when we get them back out at the next stop. Sometimes, though, you might want to leave your laptop running while the lid is shut

Note: Do NOT put your laptop in its bag while its running, as it will almost certainly overheat.
