Computers are designed to automatically enter sleep mode to conserve power and protect hardware, especially the battery. However, this can be frustrating and disruptive, especially when downloading large files or updates, or when you require quick file retrieval. To prevent your computer from entering sleep mode, you can adjust the power settings on your device, or use third-party software. This guide will explore various methods to keep your computer awake and prevent it from using battery power while asleep.

What You'll Learn
Use PowerToys Awake for Windows 11
PowerToys Awake is a utility tool for Windows 11 that is designed to keep a computer awake without requiring users to manage its power and sleep settings. This can be particularly useful when running time-consuming tasks, as it ensures that the computer does not enter sleep mode or turn off its screens.
By default, PowerToys Awake will keep the computer awake indefinitely, but you can also set a time limit for how long you want to prevent your computer from sleeping. For example, the command "PowerToys.Awake.exe --expire-at=17:00:00" will keep the computer awake until 5 PM of the current day, based on the computer's clock.
PowerToys Awake can be used directly from PowerToys Settings by toggling "Enable Awake" on. Once enabled, the application will manage the power and screen state of the computer. Alternatively, it can be executed as a standalone application from the PowerToys installation folder.
It's important to note that PowerToys Awake does not modify any Windows power plan settings and does not depend on a custom power plan configuration. Instead, it creates background threads that communicate with Windows, and once PowerToys Awake is exited, the computer will resume its standard power plan behaviour.
Additionally, PowerToys Awake offers a "Keep Screen On" switch, which will keep displays active while the tool is enabled and a custom power state is selected. This feature ensures that the connected displays do not turn off, even if the computer stays awake.

Adjust power settings to 'Never' for sleep mode
To prevent your computer from using battery power while in sleep mode, you can adjust your power settings. Here's a detailed guide to doing this:
Adjust Power Settings:
- Locate Power Settings: Go to your computer's settings and locate the power settings. The path to these settings may vary depending on your device and operating system. For example, on a Windows PC, you can access power settings by selecting Start, then Settings > System > Power & Sleep or Power Options. On a Mac, you can access power settings through the System Preferences.
- Select Sleep Settings: Once in the power settings, look for the "Sleep" or "Sleep Mode" section. Here, you'll find options to customize when and how your computer enters sleep mode.
- Set Sleep Preferences to "Never": To prevent your computer from ever entering sleep mode, set the sleep preferences to "Never." This option is usually found in a drop-down menu next to "On Battery" and "Plugged In" (for laptops) or just "Plugged In" (for desktops). Change both of these settings to "Never."
- Save Changes: After making these adjustments, be sure to click "Save Changes" or a similar option to ensure your new settings take effect.
By setting your sleep mode to "Never," your computer will no longer automatically enter sleep mode, even when idle. Keep in mind that this may result in increased power consumption, especially if you also set your screen to remain on indefinitely. Additionally, if you're using a laptop, preventing sleep mode while on battery power will drain your battery faster, so it's recommended to only set the "Plugged In" option to "Never" to preserve battery life.

Use third-party software to keep your computer awake
If you're looking to prevent your computer from using battery power while asleep, one option is to use third-party software to keep it awake. This is particularly useful if you don't have access to changing the power settings on your device.
There are several tools available that can help you achieve this. For Windows users, popular applications include Wakeful, Caffeine, Coffee FF, and Don't Sleep. These tools can simulate user activity, such as brief mouse movements, or override sleep settings to keep your computer awake. For example, Caffeine supports various command-line options, allowing you to change the time interval of the pressed key and disable the Taskbar icon. Coffee, on the other hand, checks your network connection and keeps your computer awake as long as you're downloading or uploading something. You can customize the download or upload threshold to suit your needs.
If you're a Mac user, Amphetamine is a highly recommended application that offers flexibility in keeping your device awake under various conditions. It even includes an option to disable itself when the battery reaches a certain percentage, helping to prevent accidentally running the battery empty.
By using these third-party tools, you can ensure your computer remains active without needing manual adjustments to the power settings. However, it's important to note that keeping your computer awake using third-party software on battery power can lead to faster battery drain, so it's recommended to only use this method when your device is connected to a power source.

Simulate activity with tools that mimic mouse movements
Mouse jigglers, also known as mouse movers, are devices that simulate cursor movement to prevent a computer from going into sleep mode. They are designed to keep a desktop or laptop computer in active mode by moving the cursor automatically every few seconds. This prevents the device from showing an idle status or going into inactive mode. These devices can be plugged directly into a PC or an external power source, or they can be used as software that simulates mouse activity.
There are various mouse jiggler devices available on the market, such as the Stageek Mouse Jiggler, which claims to be 100% undetectable by IT and has an on/off switch. Another option is to use software solutions such as Caffeine or Mouse Jiggler, which simulate the actions needed to keep the operating system alert and active. These utilities are free to use and can be downloaded and run as needed.
It is worth noting that while mouse jigglers can be useful for preventing a computer from going to sleep, they may also be detected by employers as some monitoring software can observe mouse movement and detect mouse jiggler usage. As such, it is recommended to communicate any monitoring practices to employees and obtain their consent, as well as comply with local privacy laws and regulations.
In addition to mouse jigglers, there are other methods to prevent a computer from going to sleep. One method is to open a fullscreen presentation or a blank website and leave an object on a key to simulate activity. Another method is to use Power Automate for desktop to create flows that simulate mouse movement and clicks.

Use hibernation mode instead of sleep mode
Hibernate mode is an excellent alternative to sleep mode if you want to prevent your computer from using battery power while it's inactive. Sleep mode uses very little power, allowing your PC to start up faster when you resume work. However, if you're stepping away from your computer for an extended period without access to a charger, hibernation mode is a better option.
Hibernation uses less power than sleep mode, ensuring your battery lasts longer. When you start your PC again, it might take a bit longer to resume, but you'll return to where you left off. This mode is ideal if you know you won't be using your laptop or tablet for a while and won't have a chance to charge the battery.
To enable hibernation on your Windows PC, first, check if the option is available. Open Power Options by selecting Start, then Settings > System > Power & Sleep > Additional Power Settings. Select "Choose what the power button does," and then choose "Change settings that are currently unavailable." Under "Shutdown settings," select the "Hibernate" checkbox if available, and then click "Save changes."
You can now hibernate your PC by selecting Start and then Power > Hibernate. Alternatively, press the Windows logo key + X on your keyboard, then select "Shut down or sign out" followed by "Hibernate." You can also set your PC to hibernate automatically after a certain period of inactivity or when the lid is closed. This can be adjusted in the Advanced settings for your power plan.
It's important to note that not all PCs have a hibernate option. For example, PCs with InstantGo don't offer hibernation. Additionally, if you have devices connected to your PC, such as monitors, printers, or scanners, you may need to reconnect them or update their drivers after waking up your computer from hibernation.
