To turn off, or not to turn off?

“Should I turn off my computer when I’m done using it?” The short answer is: “it doesn’t matter”. Your computer is just a machine and is happy to run 24x7. But there are two reasons why you may want to shut it down at night or at least periodically: (1) Energy use – even in sleep mode a computer and monitor draw a small amount of power; (2) Updates – some operating system updates can only be fully applied with a reboot. My usual advice is to shut down or restart your computer once a week, and any more frequently is entirely up to you.
