Many people find it convenient to be able to wake their computers from sleep mode by moving their mouse. However, some users have reported issues with their computers waking from sleep mode unintentionally due to slight movements of their mouse. While there are some software solutions to this problem, such as disabling Allow this device to wake the computer in Device Manager, these solutions do not always work. Some users have found that the only way to prevent their computer from waking due to mouse movement is to physically turn off their mouse or switch its input to a different device.

Disable Allow this device to wake the computer in Device Manager
Disabling "Allow this device to wake the computer" in Device Manager is one way to prevent your mouse from waking your computer from sleep mode. However, this method may not work for all computers.
To disable "Allow this device to wake the computer" in Device Manager, you must first open Device Manager (devmgmt.msc). Then, expand the relevant device category (e.g., "Network adapters" or "Keyboards") and double-click/tap on the device you want to disable. In the new window, click/tap on the "Power Management" tab. Finally, uncheck the box for "Allow this device to wake the computer" and click/tap "OK."
It is important to note that this method may not work for all devices, especially newer systems. For example, one user reported that disabling "Allow this device to wake the computer" for all devices in Device Manager did not prevent their mouse from waking their Asus laptop. This issue may be due to system updates or the use of different USB ports, which can cause the device manager to identify the mouse as a new device.
Additionally, some newer systems have replaced the traditional "Sleep" state (S3) with a new mode (S0 Sleep or Modern Standby), where the computer stays on but allows fewer programs to run. The Device Manager settings for allowing a device to wake the computer may only apply to the older S3 Sleep mode, and waking the computer with mouse movement may be a default feature of Modern Standby.
To completely prevent your mouse from waking your computer, you may need to physically turn off your mouse or switch its input to a different device. Alternatively, you can try to disable all devices related to the keyboard, as the mouse may still send a signal to wake the computer even when disabled in Device Manager.

Disable Modern standby on your computer/OS
Modern Standby (S0) is a newer sleep state and a successor to the legacy Sleep Standby (S3) mode. It replaces the standard sleep feature and puts your laptop in a lower power state when idle. In this sleep state, your system is kept awake under minimum power consumption to perform background tasks such as syncing email and notifications over the internet. It also features an instant on/off feature that gives you a faster transition between the on and off state, similar to your smartphone.
While there are other perks to using Modern Standby, not everyone prefers it over the classic S3 sleep mode. If, for any reason, you need to disable Modern Standby in Windows 10 and 11, you can use a registry script. This is the easiest way to get things done without having to navigate your way through the Windows registry. Before you attempt to make any changes to your Windows registry, it is recommended that you create a restore point. This should help you recover your system in case something goes wrong during the process.
- Press Win + R to open Run.
- Type notepad and click OK to open a new Notepad file.
- Copy and paste the following script into the notepad file: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power]"PlatformAoAcOverride"=dword:00000000
- Click on File and select Save As.
- Enter the File name as Disable_Modern_Standby.reg.
- Click the Save as type drop-down and select All files.
- Click Save to save the registry file.
- Next, double-click on the Disable_Modern_Standby.reg file and click Yes when prompted by UAC.
You can also use the Command Prompt to disable Modern Standby on your PC. This method uses the reg commands executed via the Command Prompt to modify the Windows registry. Here are the steps:
- Press Win + X to open Run.
- Click on Windows Terminal (Admin) to open the terminal with administrative privileges.
- In the Windows Terminal window, copy and paste the following reg command: reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0
Please note that disabling Modern Standby may not always work as expected. Some users have reported that even after disabling "Allow this device to wake the computer" in Device Manager, their computers still wake up from sleep mode due to mouse movement. This seems to be a bug in Windows, and there is no definitive solution other than physically turning off the mouse or switching its input to a different device.

Use the Sleep key on your keyboard
If you want to wake your computer from sleep mode, you can use the Sleep key on your keyboard. This is a dedicated key on some keyboards, and you can press it to put your computer to sleep and then press it again to wake it up. If your keyboard does not have a dedicated Sleep key, you can program one by following these steps:
- Open the Keyboard control panel.
- Type "keyboard" in the Start Search box, then click Keyboard or Microsoft Keyboard in the Programs list.
- In Windows XP and earlier versions, click Start, click Run, type Control keyboard, and then click OK.
- On the Key Settings tab, double-click the key that you want to change to access the Reassign a Key wizard.
- Select the "Start a Program, Web page, or file" option, and then click Next.
- To enable this key to start Sleep mode, run the following command: rundll32.exe powrprof.dll,SetSuspendState. Note that there are spaces before and after powrprof.dll.
If you are using a Bluetooth keyboard, it may be unable to wake your computer from sleep. In this case, you may need to press the power button to wake up your computer. Additionally, if you are using Windows Vista, ensure that you have updated to Service Pack 1 or a later version, as earlier versions may have issues with the Sleep key functionality.

Use the Power button on your computer
If you want to wake your computer from sleep mode using your mouse, you may first need to configure your computer's settings. This is because, on some computers, the default setting is that only the power button can wake the computer from sleep mode.
To change this setting, you can try the following:
- Open Power Options by selecting Start, then Settings, System, Power & Sleep, and Additional Power Settings.
- Select "Choose what the power button does", and then "Change settings that are currently unavailable".
- Under Shutdown settings, select the "Hibernate" checkbox (if available), and then select "Save changes".
- Now try moving your mouse to wake your computer from sleep mode.
If this does not work, you may need to change your BIOS settings. First, check if your computer supports Advanced Configuration and Power Interface (ACPI). If it does not, you will need to press the power button to wake your computer. If your computer does support ACPI, ensure that "Allow this device to wake the computer" is enabled in the Keyboard control panel item.
Finally, if you are using a Bluetooth mouse, you may need to customise your laptop's Bluetooth stack to allow wake functionality.

Download software to simulate mouse movement
Mouse Jigglers are a popular way to prevent your computer from going to sleep. They simulate mouse movements to prevent screensavers or sleep modes from activating. There are two main types of mouse jigglers: physical and software.
Software mouse jigglers are programs that you can download and install on your computer. One such program is called Mouse Jiggler, developed by Alistair J. R. Young. It is a free utility and tool app that simulates cursor movements, preventing the system from registering inactivity and avoiding automatic logouts or screen dimming. Mouse Jiggler offers a Zen Mode, which performs this task without visibly moving the cursor, ensuring that your workflow remains undisturbed. It is available for download on PC and Windows.
Another software jiggler option is Caffeine, which simulates the press of the F15 key (or Shift key) every 59 seconds to keep your machine active.
While software mouse jigglers are convenient, some sources advise against using them, as they may be detected as malicious by antivirus programs or interfere with your work.
Therefore, if you prefer a physical device that doesn't require any installation, you can opt for a USB mouse jiggler. These devices connect to your computer's USB port and simulate mouse movements to keep it awake. They are often designed to be undetectable, recognized as regular mice rather than unknown USB devices. Examples of USB mouse jigglers include the Phiginoo Mouse Mover, TECKNET Mouse Jiggler, and Rii Mouse Jiggler.
