How to Prevent Your Computer from Sleeping

Adjusting Power Settings
One of the most straightforward ways to prevent your computer from sleeping is by adjusting your power settings. On Windows, you can access power options by searching for “Power Options” in the Start menu or Control Panel. From there, you can choose a power plan that best suits your needs or customize an existing plan.
For instance, you can change the “Put the computer to sleep” option to “Never” or increase the time until the computer sleeps. On a Mac, you can access power options by going to System Preferences > Energy Saver. You can then adjust the slider to “Never” or customize the time settings for the computer and display to sleep. By making these changes, your computer will stay awake for longer periods, even if you’re not actively using it.
Using Software or Apps
There are various software or apps that you can use to prevent your computer from sleeping. For example, Caffeine is a free program for Windows and Mac that keeps your computer awake by simulating keystrokes at regular intervals. When you activate Caffeine, it will prevent your computer from going into sleep mode until you turn it off manually.
Another option is Amphetamine, a similar app available exclusively for Mac. It allows you to create custom profiles for different scenarios and applications to keep your computer awake. You can also schedule when you want Amphetamine to activate or deactivate, so you don’t have to worry about forgetting to turn it off.
Some web browsers, such as Chrome and Firefox, also have extensions that can prevent your computer from sleeping while you’re using them. These extensions are handy if you’re working on a task that requires you to keep a browser open for a long time, such as downloading a large file or streaming media.
Keeping the Mouse or Keyboard Active
Another way to keep your computer from sleeping is to keep the mouse or keyboard active. On Windows, you can go to “Control Panel > Hardware and Sound > Power Options > Edit Plan Settings” and choose “Change advanced power settings.” From there, you can find the “USB settings > USB selective suspend setting” option and set it to “Disabled.” This will prevent your computer from suspending the USB devices, such as a mouse or keyboard, which will keep them active.
On a Mac, you can go to System Preferences > Keyboard > Keyboard and enable “Prevent computer from sleeping automatically when the display is off.” This setting will ensure that the computer doesn’t go to sleep mode when the screen is turned off. You can also download third-party apps like Mouse Jiggler, which moves your mouse cursor slightly every few seconds to prevent your computer from sleeping.
Disabling Sleep Mode Completely
If you need your computer to be active at all times, you can choose to disable sleep mode entirely. However, this option can consume a lot of energy, and your computer may become overheated if you use it for extended periods. Disabling sleep mode can also impact your computer’s performance and lifespan.
On Windows, you can disable sleep mode by going to “Control Panel > Hardware and Sound > Power Options > Change plan settings > Change advanced power settings.” From there, you can find the “Sleep” option and set it to “Never.” On a Mac, you can go to System Preferences > Energy Saver and move the “Computer sleep” and “Display sleep” sliders to “Never.”
Remember to only disable sleep mode if you have a specific reason for doing so, and keep an eye on your computer’s temperature and performance if you choose this option.
Updating Your Operating System and Drivers
Updating your operating system and drivers can also help prevent your computer from sleeping unexpectedly. Sometimes, outdated drivers or software can cause your computer to go to sleep mode, even if you have not set it to do so.
On Windows, you can check for updates by going to “Settings > Update & Security > Windows Update.” On a Mac, you can check for updates by going to System Preferences > Software Update. If there are any updates available, make sure to install them to ensure your computer is running smoothly.
You can also check for driver updates on your computer’s manufacturer’s website or using a third-party driver updater tool. Keeping your drivers up-to-date can help prevent unexpected sleep mode and improve your computer’s performance.
