Tip 2. Going To Sleep

You can put your mac to sleep either by shutting the lid or by clicking on Sleep in the apple menu (top left hand corner of the screen). When this happens your mac writes everything from RAM to a file so it can remember what you were doing before it slept. It's sort of like you writing down everything your thinking about before you go to bed so you remember what you were thinking of when you wake up.

What's important though is that when your mac is creating this file it should be kept still because it's bad to move it whilst it's writing to disk. When your mac is ready to be picked up and carried about it will wink at you continuously (the pulsing white light on the front). The process of writing this sleep file takes only about a minute.
