What You'll Learn

Check for non-compatible devices
If you are experiencing sleep-wake issues with Windows 10, it could be because of non-compatible devices connected to your computer. Many manufacturers take time to roll out the required updates for their equipment to be completely compatible with the newer version of Windows. These devices can include your printer, gaming consoles, and other peripherals.
To check for non-compatible devices, you can try the following steps:
- Head over to the manufacturer's website and confirm the compatibility of the device. If the device is not compatible, disconnect it from your computer and check if the sleep problem persists.
- You can also try updating your drivers through the Device Manager. Right-click on a driver and select "Update driver". If Windows 10 doesn't find the drivers, check the driver manufacturer's website for the latest compatible drivers.
- Use the process of elimination by disabling devices in Device Manager to identify any non-compatible devices. Open the Start menu, search for "Device Manager", and locate the device you want to configure. Right-click on it, select "Properties", and open the Power Management tab. Uncheck the "Allow this device to wake the computer" option.
- Check your BIOS settings to see if your machine supports the deep sleep function. An outdated BIOS can become incompatible with the OS, causing the system not to wake from sleep. Updating the BIOS to the latest version may solve the problem, but proceed with caution as incorrect updates can damage your system.
- If you are unsure which device is causing the issue, try removing all your USB devices the next time your computer is put to sleep. If it doesn't wake up on its own, leave one device plugged in and continue this process until you find the problematic hardware.

Change wake-up timer settings
Wake timers are timed events that wake your PC from sleep and hibernation states at a specific time to perform scheduled tasks. They are important for things like required reboots after a Windows update. You can change your wake-up timer settings by following these steps:
- Open the advanced power settings of the power plan you want to enable or disable wake timers for.
- Expand open Sleep and Allow wake timers.
- Select Enable, Disable (the default setting when on battery), or Important Wake Timers Only (the default setting when plugged in).
- Click OK to apply the changes.
You can also change your power and sleep settings by going to Start, selecting Settings > System > Power & Sleep, and choosing how long you want your device to wait before turning off the screen and going to sleep when you're not using it.
Additionally, you can use Command Prompt and Windows PowerShell to find wake timers that wake up your system automatically. You can also use the Task Scheduler to establish your wake patterns and conditions, define wake triggers, and set expiration policies for temporary wake schedules.

Check for power requests
If your Windows 10 PC is not going to sleep or is waking up from sleep unexpectedly, you can check for power requests to identify the issue.
To see a log of all power requests in Windows 10, launch Command Prompt as an administrator. Then, execute the following command: `powercfg -requests`. This will present a list of active power requests. All categories should be empty. If they are not, make a note of what is prompting the power request. For example, in the log, you might see a "Caller_type" with process "synergyc.exe" and "request" type as "SYSTEM", indicating that this process is preventing the PC from entering sleep mode.
You can also use the command `powercfg -lastwake` to identify which device triggered the wake-up event. In the log, you will see the device that woke the computer, such as the power button or Ethernet adapter. If you identify a device that is causing unexpected wake-up events, you can open the device driver in Device Manager, right-click the driver, and choose Properties. In the Power Management tab, uncheck "Allow this device to wake the computer". Alternatively, you can leave this option enabled and select "Only allow a magic packet to wake the computer" to prevent everything except Wake-On-Lan packets from waking up your PC.
Additionally, you can try generating a Power Efficiency Diagnostics Report to find the problem. This report will help you identify the driver or utility that is preventing your Windows 10 PC from sleeping properly.

Use Windows Update tools
If your Windows 10 computer keeps waking up from sleep mode, there are a few settings you can tweak to fix the problem.
Firstly, you can use Windows Update's built-in tools to more meticulously schedule updates and reboots. In Windows 10, go to Settings > Update & Security > Windows Update to pause updates or change active hours. You can also defer updates until you have time to install them.
If you need to dig a little deeper into your settings, you will need a Pro or Enterprise edition of Windows 10 to access the Group Policy Editor. From here, find the following setting: Computer Configuration > Administrative Templates > Windows Components > Windows Updates > Enabling Windows Update Power Management to automatically wake up the system to install scheduled updates. Double-click it and set it to Disabled.
You can also open an Administrative PowerShell command prompt by going to Start, typing 'PowerShell', and then pressing Ctrl+Shift+Enter. This will allow you to run a command to find and remove the permissions of all tasks that can wake your PC.
Additionally, you can disable the machine's ability to wake itself up for tasks. To do this, open the Start menu, search for "Edit Power Plan," and click on Change Advanced Settings. Then, head to Sleep > Allow Wake Timers and change Battery and Plugged In to Disabled for all power plans.
Finally, you can also remove the ability of devices to wake up your computer. Go to the Device Manager in your Control Panel, and under the Power Management tab, remove their ability to wake your computer up.

Check hardware and power options
If your Windows 10 PC is acting up and not going to sleep or waking up randomly, there are a few things you can do to get to the root of the problem.
First, check if your machine has entered sleep mode. Sometimes, the cause of random hibernation or shutdown is overheating. If the internal temperature reaches a certain level, your PC will either enter hibernation mode or shut down to protect its hardware components. You can use a third-party app to monitor the temperature of your PC.
Next, check your hardware and power options. If you have recently upgraded to Windows 10 or have done a major update, specific power-related settings might have gotten corrupted. Open Settings > System. Then, under Power & Sleep Settings, click Additional Power Settings. From here, select 'Choose when to turn off the display' and then 'Restore default settings for this plan'. Your PC might also go to sleep at random if you set up the screensaver incorrectly. A screensaver utility allows your PC to go into a sleep state to preserve energy.
If you are using a Bluetooth device, the keyboard may be unable to wake the system. You can change the Power settings in Windows to not go into Sleep mode when plugged in. The Microsoft Bluetooth stack or your laptop’s proprietary Bluetooth stack may allow customization to allow wake-up by using Bluetooth devices.
If you are using the original version of Vista and have not updated to the latest available Service Pack, updating to Service Pack 1 or a later version may resolve this problem.
If you are still facing issues, you can run the Windows Power Troubleshooter to adjust your computer's power settings. The Power Troubleshooter checks your computer's timeout settings, which determine how long the computer waits before turning off the monitor display or entering sleep mode. Adjusting these settings can help you conserve power and extend your laptop's battery life.
If none of the above work, you may have to dig into the wake timers set on your computer. Open the Start menu, search for "Edit Power Plan," and click Change Advanced Settings in the Edit Plan Settings window. Head to Sleep > Allow Wake Timers and change Battery and Plugged In to Disabled. Repeat this process for all your power plans in the drop-down menu at the top.
