What You'll Learn
Keyboard, mouse, or network adapter
If your Windows 10 PC is waking up from sleep mode, your keyboard, mouse, or network adapter could be the culprits. Here's how to manage each of these devices in relation to sleep mode:
Keyboard and Mouse
Sometimes, your computer will not wake up from sleep mode because your keyboard or mouse has been prevented from doing so. To allow your keyboard and mouse to wake up your PC, you need to confirm that they are allowed to do so:
- Press the Windows logo key and R at the same time, then type "devmgmt.msc" and press Enter.
- Double-click on "Keyboards" and select your keyboard device.
- Click on the "Power Management" tab and check the box "Allow this device to wake the computer". Click OK.
- Expand the category "Mice and other pointing devices" and repeat the process for all your mouse devices, including your touchpad.
If you use a Bluetooth keyboard or mouse, your computer might not receive Bluetooth signals while it's asleep. You can address this by updating your Bluetooth driver or getting a newer Bluetooth adapter with better power management.
Additionally, you can try disabling hybrid sleep and enabling wake timers:
- Press the Windows logo key and R simultaneously.
- Type "powercfg.cpl" and press Enter.
- Click on "Change plan settings" and then "Change advanced power settings".
- Double-click on "Sleep", set "Allow hybrid sleep" to Off, and set "Allow wake timers" to Enable.
- Click "Apply" followed by "OK", and then restart your computer.
If you're still facing issues with your mouse waking up your PC, there is an option to disable the mouse from waking up the computer. However, this doesn't always work due to a bug in Windows.
Network Adapter
If your network adapter turns off after your Windows 10 PC recovers from sleep mode, you can try the following:
- Go to Device Manager and select the 'Power Management' tab in the network adapter's properties.
- Disable the option for the adapter to turn off to prevent it from sleeping.
Alternatively, you can try restarting the network adapter using PowerShell:
- Use "Get-NetAdapter" to list the network adapters and note the Ethernet adapter name.
- Use "Restart-NetAdapter" to restart the adapter (must be run as Administrator).

Scheduled tasks
The Task Scheduler in Windows 10 is a built-in tool that can automatically start programs or scripts at pre-defined times or after specified time intervals on a chosen computer. It allows users to automate tasks, such as running programs, scripts, or batch files, at specific times or intervals.
To create a scheduled task to wake up your Windows 10 PC, you can follow these general steps:
- Open the Task Scheduler.
- Create a new task with a descriptive name, such as "Wake Up".
- Configure the task to "Run whether user is logged on or not" and select the "Run with highest privileges" option.
- Set the "Configure for" option to "Windows 10".
- Switch to the "Triggers" tab and create a new trigger.
- Select the "On a schedule" option and set the desired frequency (daily, weekly, monthly, etc.).
- Go to the "Conditions" tab and ensure that "Wake the computer to run this task" is selected.
- Move on to the "Actions" tab and specify the tasks to be performed after the PC wakes up, such as an antivirus scan or an online download.
It is important to note that some users have reported issues with the Task Scheduler not reliably waking their computers from sleep mode. One possible solution is to enable "Wake Timers" in the advanced power settings. Additionally, checking the BIOS settings and ensuring that the High Precision Event Timer (HPET) is enabled can also help resolve this issue.
Another approach is to use third-party power management programs or reliable backup programs like AOMEI Backupper Standard or Qiling Disk Master Standard. These programs can automate the process of waking up and putting your computer to sleep, without the need for complex scripts.

Windows Update
If your Windows 10 PC wakes up from sleep by itself, it can cause inconveniences and unnecessary power consumption. There are a few ways to diagnose the problem and keep your computer down for the night.
Firstly, Windows may tell you a USB device is waking your computer. To find the offending device, you can remove all your USB devices the next time you put your computer to sleep, and see if it wakes up on its own. If it doesn't, leave one device plugged in the next time you put it to sleep. Keep doing this until you find the offending device. Once you find the problematic hardware, open the Start menu and search for "Device Manager". Find the device in the resulting list, right-click on it, and select Properties. Then, click on the Power Management tab and uncheck the "Allow this device to wake the computer" option. Click OK and reboot your device.
Another reason for your computer waking up from sleep could be Windows Update. To solve this problem, try using Windows Update's built-in tools to more meticulously schedule updates and reboots. Set your Active Hours and defer updates until you have time to install them. In Windows 10, head to Settings > Update & Security > Windows Update to pause updates or change active hours.
Additionally, you can open the Start menu, search for "Edit Power Plan", and click on "Change Advanced Settings". Head to Sleep > Allow Wake Timers and change Battery and Plugged In to Disabled.
If you want to know exactly what woke your computer up, open the Start menu and search "cmd". Right-click on the Command Prompt entry and choose "Run As Administrator". Type the following command and press Enter. This should give you a clear answer.

Outdated device drivers
To resolve this issue, it is recommended to update the device drivers to the most recent version compatible with your system and operating system. This can be done manually by downloading and installing the latest drivers from the manufacturer's support site. However, if you do not have the time or technical skills to update the drivers manually, you can use a driver update tool such as Driver Easy or DriverFinder, which can automatically recognize your system and install the correct drivers.
In addition to updating device drivers, there are several other steps you can take to prevent your Windows 10 PC from waking up from sleep mode unexpectedly:
- Disable specific devices from waking the computer: In the Device Manager, locate the device (such as the keyboard, mouse, or network adapter), open its properties, and uncheck the "Allow this device to wake the computer" option.
- Disable Wake-on-LAN: If your PC has multiple network adapters, repeat these steps for each adapter.
- Change power settings: Go to Sleep > Allow Wake Timers and disable the "Battery" and "Plugged In" options.
- Run a command prompt: Open Command Prompt as an administrator and use the powercfg command to identify which tasks, applications, or devices are causing the PC to wake up.
- Disable scheduled tasks: In Task Scheduler, locate the Reboot task, right-click it, and choose "Disable" to prevent scheduled tasks from waking up your PC.
By following these steps and ensuring your device drivers are up to date, you can prevent your Windows 10 PC from randomly waking up from sleep mode.

Fast startup
While this feature can save valuable seconds from your PC's boot time, it may not always work perfectly. For example, updates may not be installed with Fast Startup enabled, and it can also interfere with some system updates that require a full shutdown. It can also cause issues with Wake-on-LAN, and some users have reported that power buttons on their keyboards don't work with it enabled.
To disable Fast Startup, press the Windows logo key and R at the same time, then copy and paste powercfg.cpl into the box and click OK. Then click "Choose what the power buttons do".
