Hibernate uses no power, but takes a lot longer to restart. Hibernate does something similar, but instead of storing everything you’re doing in RAM, it creates a special file on your hard drive to store everything and then shuts down the computer completely. This means when you wake it up, it will return to a working state quickly and all your apps and data will be where you left them before it went to sleep. Sleep mode puts your computer in a low-power usage state, but keeps everything right where you left it by keeping the active memory (RAM) powered. To minimize the use of power when you aren’t using your computer, you can set your computer to either go to sleep or hibernate after a period of inactivity. Unless you’re still using a computer that’s over a decade old, the power savings from turning it off every night is negligible, as long as you have it set up to go to sleep when it hasn’t been used for a specific time.ĭisplays can be one of the more power-hungry components, so running a screen saver that keeps changing what’s on the screen will use more power then setting your screen to go black or better yet, just turn off the display when you know you aren’t going to use it for a while. Laptop computers typically use a fraction of the power that a desktop computer requires so even if it’s plugged in all the time, the consumption is pretty minimal. Not only are they more efficient, individual internal components can be designed to go to sleep when they aren’t being used in order to reduce heat and extend the life of the component. There was a time when computers, especially those using tube style monitors (CRTs), consumed quite a bit of electricity, but today’s computers are much more efficient. For just about everyone else, it can get more complicated.

If you use your computer for a short period every day, turning it off when you’re done probably makes sense. Q: Should I turn off my computer every night or leave it on?Īlthough this may seem like a simple question, the answer for each person will be different depending upon how often you use the computer and how many automated tasks the computer is set up to perform.
