Sleep Timer for Your Computer:
The Ultimate Guide

One of the common complaints about computers is that their battery life isn't always the best. As a result, people may find themselves frequently needing to charge their devices. When this happens at an inconvenient time, it can throw a wrench in your plans. There are several ways to help extend your computer's battery life, but a simple one is using a sleep timer.

What is a sleep timer?

A sleep timer is a function that dictates how long your computer will sit idle before going into power-saving mode. Your computer is considered to be idle if there is no movement occurring on the screen.

So, for example, you could instruct your computer to have a five-minute sleep timer, which means after five means of idle time, it will automatically go into power-saving mode. This can help prolong your battery life.

How to use sleep timers for your computer

Depending on whether you are using a Mac or Windows PC, the process for setting a sleep timer looks a little different. Here are directions on how to do it for both Mac and Windows.


  1. Click on the Apple icon on the top left of the toolbar.
  2. Go to System Preferences-then Energy saver-then Power adapter.
  3. On a Mac laptop, two tabs will pop up: Battery and Power adapter. Each has its own settings. An iMac will only have one option since your device is always plugged in.
  4. Using the Computer sleep slider, set how quickly you want your device to go into sleep mode after idling.
  5. Set the sleep mode for your monitor using the Display sleep slider. This will turn your display off after a certain period of inactivity.


  1. Press Windows key + Q, which will open the search menu.
  2. In the search menu, type "Sleep."
  3. Several options will appear. Click on "Power and sleep settings."
  4. Once that window opens, scroll down to "Sleep" This will give you several drop-down menus.
  5. Click on the drop-down menus to open them and then choose how long you want your device to sit idle before going to sleep.
  6. Once you have selected your sleep timer, close the window, and your settings will be saved.
