启用睡眠模式的电脑应在设置中指定的时间到期后进入睡眠模式。如果没有发生这种情况，则令人担忧，因为您的系统出现问题。

当Windows 10^{(Windows 10)}无法睡眠时，您可以按照一些方法来解决此问题。这些方法包括确保启用睡眠模式以及正确配置电源设置^{(power settings)}。

此外，在您开始之前，有必要检查您的BIOS设置以确保您的 PC 已启用挂起或睡眠模式。如果在BIOS^(BIOS)中禁用了该功能，则以下修复均无济于事。戴尔^(Dell)有一篇关于如何在 BIOS 中启用睡眠模式^{(enable sleep mode in the BIOS)}的好文章。如果您有不同的计算机制造商，只需谷歌^(Google)制造商名称和睡眠模式即可获取说明。

启用睡眠模式^{(Enable Sleep Mode)}

检查PC 上睡眠模式的状态。^{(sleep mode)}您或其他人可能出于某种原因关闭了该模式，或者它可能已被第三方应用程序更改。

1. 打开“开始^(Start)”菜单，搜索“编辑电源计划^{(Edit power plan)}”，然后在搜索结果中选择该选项。

1. 在以下屏幕上，确保将计算机进入睡眠状态^{(Put the computer to sleep)}旁边的下拉菜单未设置为从不^(Never)。
   

1. 如果该选项设置为Never，请选择下拉菜单并设置 PC 应休眠的时间。

查找阻止 PC 睡眠的程序^{(Find the Programs Preventing PC Sleep)}

您安装的程序可能会导致您的 PC 无法进入睡眠模式，并且通常很难找到导致此问题的程序。

幸运的是，Windows 10 包含一个命令^{(Windows 10 includes a command)}，可让您查看阻止 PC 进入睡眠模式的程序。

1. 启动开始^(Start)菜单，搜索命令提示符^{(Command Prompt)}，然后选择以管理员身份运行^{(Run as administrator)}。

1. 在用户帐户控制^{(User Account Control)}提示中选择是。^(Yes)
2. 在命令提示符^{(Command Prompt)}窗口中，键入以下命令并按Enter：powercfg /requests
3. 命令提示符^{(Command Prompt)}现在显示阻止您的 PC 进入睡眠模式的程序列表。

1. 退出命令提示符^{(Command Prompt)}窗口中显示的程序。然后，查看您的 PC 是否成功进入睡眠模式。如果是这样，您可以阻止该程序^{(prevent that program from starting up)}在 Windows 启动时启动。

如果此处弹出其他内容，例如 srvnet，请务必阅读我们关于如何解决该问题的深入指南。^{(in-depth guide)}

关闭所有打开的程序^{(Close All Open Programs)}

如果您的 Windows 10 PC 即使在关闭特定程序后仍无法睡眠，请关闭所有打开的程序^{(close all of the open programs)}，看看这是否有任何区别。

您可以通过在程序的文件^(File)菜单中选择退出^(Exit)选项来退出大多数程序。对系统托盘上的所有程序也这样做。

关闭所有打开的应用程序后，请等待 PC 通常进入睡眠模式的时间。如果它毫无问题地进入睡眠状态，则说明您的某个程序存在问题，您需要从 PC 中删除有问题的程序。

要检查导致问题的程序，请一次关闭一个程序，然后查看睡眠模式问题是否仍然存在。更准确地说，最好执行Windows 10的干净启动^{(perform a clean boot)}。即使您关闭了任务栏中所有打开的应用程序，这也会关闭任何可能正在运行的后台进程。

更改电源选项^{(Change Power Options)}

Windows 10 的电源设置可能会干扰睡眠模式的工作并导致您的电脑绕过睡眠模式。在这种情况下，请检查并确保电源设置不是这里的罪魁祸首。您甚至可以重置设置以确保安全。

1. 访问“开始^(Start)”菜单，搜索“编辑电源计划^{(Edit power plan)}”，然后选择该选项。
   
2. 在以下屏幕上选择更改高级电源设置。^{(Change advanced power settings)}

1. 在打开的电源选项^{(Power Options)}窗口中，展开多媒体设置^{(Multimedia settings)}选项并选择共享媒体时^{(When sharing media)}。
   
2. 确保将On battery和Plugged in选项都设置为Allow the computer to sleep。然后，选择应用^(Apply)，然后在底部选择确定。^(OK)

1. 如果您修改了任何其他选项但不记得这些选项是什么，您可以通过选择“恢复计划默认值”^{(Restore plan defaults)}按钮来重置所有设置。

关闭屏幕保护程序^{(Turn the Screen Saver Off)}

当您的 PC 拒绝进入睡眠模式时，禁用屏幕保护程序^{(screen saver)}是值得的。然后，如果您想要恢复屏幕保护程序，您可以随时打开它。

1. 打开开始^(Start)菜单，搜索更改屏幕保护程序^{(Change screen saver)}，然后在结果中选择该选项。

1. 在打开的窗口中，从屏幕保护程序^{(Screen saver)}下拉菜单中选择无。^(None)

1. 选择应用^(Apply)，然后在底部选择确定^(OK)以保存更改。

防止设备唤醒您的 PC^{(Prevent a Device From Waking Your PC)}

Windows 允许大多数连接的设备（例如鼠标和触控板）唤醒您的 PC。如果您错误地移动鼠标或触摸触控板，这可能会阻止您的Windows 10 PC 进入睡眠模式。

要从始终停止睡眠模式解决此问题，请禁用允许连接设备唤醒计算机的选项。

1. 打开开始^(Start)菜单，搜索设备管理器^{(Device Manager)}，然后在结果中选择设备管理器^{(Device Manager)}。

1. 在打开的窗口中，选择鼠标和其他指针设备^{(Mice and other pointing devices)}。
   
2. 从展开的菜单中，右键单击您的设备并选择Properties。

1. 转到电源管理^{(Power Management)}选项卡并取消选择允许此设备唤醒计算机^{(Allow this device to wake the computer)}选项。

1. 选择底部的确定^(OK)以保存更改。

How to Fix a Windows 10 PC That Won’t Sleep

Sleep mоdе-enabled PCs should enter sleep modе after the expiry of the ѕpecified time in ѕettings. If this doesn’t happen, it’s a cause of concern as something is off with your syѕtem.

You can follow a few methods to get around the issue when Windows 10 won’t sleep. These methods include ensuring sleep mode is enabled and that the power settings are configured properly.

Also, before you get started, it’s worth checking your BIOS settings to make sure your PC is enabled for suspend or sleep mode. If that feature is disabled in the BIOS, none of the fixes below will help. Dell has a good article on how to enable sleep mode in the BIOS. If you have a different computer manufacturer, just Google the manufacturer name along with sleep mode to get instructions.

Enable Sleep Mode

Check the status of sleep mode on your PC. You or someone else may have turned off the mode for some reason or it could have been changed by the third-party app.

1. Open the Start menu, search for Edit power plan, and select that option in the search results.

1. On the following screen, ensure the dropdown menus next to Put the computer to sleep are not set to Never.
   

1. If the option is set to Never, select the dropdown and set a time after which the PC should sleep.

Find the Programs Preventing PC Sleep

Your installed programs can cause your PC not to go into sleep mode, and it’s often difficult to find what program is causing this issue.

Luckily, Windows 10 includes a command to let you view the programs that prevent your PC from entering sleep mode.

1. Launch the Start menu, search for Command Prompt, and select Run as administrator.

1. Select Yes in the User Account Control prompt.
2. On the Command Prompt window, type the following command and press Enter: powercfg /requests
3. Command Prompt now displays a list of programs that prevent your PC from going into sleep mode.

1. Quit the programs shown in the Command Prompt window. Then, see if your PC successfully goes into sleep mode. If it does, you can prevent that program from starting up when Windows boots.

If something else pops up here like srvnet, make sure read our in-depth guide on how to fix that issue.

Close All Open Programs

If your Windows 10 PC won’t sleep even after closing specific programs, close all of the open programs and see if this makes any difference.

You can quit most programs by selecting the Exit option in the program’s File menu. Do this for all of the programs on the system tray as well.

Once you’ve closed all your open apps, wait for the time after which your PC usually goes into sleep mode. If it sleeps without issues, there’s an issue with one of your programs, and you need to remove the problematic ones from your PC.

To check what program is causing the issue, close one program at a time and see if the sleep mode issue persists. To be even more precise, it’s better to perform a clean boot of Windows 10. This will also shutdown any background processes that might be running even after you close all the open apps in the taskbar.

Change Power Options

Windows 10’s power settings can interfere with the workings of sleep mode and cause your PC to bypass sleep mode. In this case, check and ensure that the power settings aren’t the culprit here. You can even reset the settings just to be sure.

1. Access the Start menu, search for Edit power plan, and select that option.
   
2. Select Change advanced power settings on the following screen.

1. In the Power Options window that opens, expand the Multimedia settings option and select When sharing media.
   
2. Ensure both On battery and Plugged in options are set to Allow the computer to sleep. Then, select Apply and then OK at the bottom.

1. If you’ve modified any other options but you can’t recall what those were, you can reset all the settings by selecting the Restore plan defaults button.

Turn the Screen Saver Off

It’s worth disabling the screen saver when your PC refuses to enter sleep mode. Then, if you want the screen saver back, you can turn it on anytime you want.

1. Open the Start menu, search for Change screen saver, and select that option in the results.

1. In the window that opens, select None from the Screen saver dropdown menu.

1. Select Apply followed by OK at the bottom to save your changes.

Prevent a Device From Waking Your PC

Windows allows most of your connected devices, like your mouse and trackpad, to wake your PC. If you mistakenly move your mouse around or touch the trackpad, this can prevent your Windows 10 PC  from entering sleep mode.

To fix this from always stopping sleep mode, disable the option that allows connected devices to wake your computer.

1. Open the Start menu, search for Device Manager, and select Device Manager in the results.

1. On the window that opens, select Mice and other pointing devices.
   
2. From the expanded menu, right-click your device and select Properties.

1. Go to the Power Management tab and deselect the Allow this device to wake the computer option.

1. Select OK at the bottom to save your changes.

Disable Hybrid Sleep

Windows 10 offers a feature called hybrid sleep that combines both sleep and hibernation features into one. If this is enabled, it’s worth toggling it off to see if you can enter the normal sleep mode.

1. Search for Edit power plan in the Start menu and select the Edit power plan option.
2. Select Change advanced power settings on the following screen.
3. On the Power Options window that opens, expand the Sleep option.
4. In the expanded menu, select Allow hybrid sleep and ensure both On battery and Plugged in options are set to Off.

Run Power Troubleshooter

In some cases, it’s difficult to recognize the reason your Windows 10 PC won’t sleep. In these situations, one thing you can rely on is one of Windows 10’s troubleshooters.

Windows 10 comes with many troubleshooters that automatically detect and fix issues on your computer. For your specific problem, you can use the power troubleshooter.

1. Open Windows 10’s Settings app by pressing Windows + I keys at the same time.
   
2. In Settings, select Update & Security at the bottom.

1. Select Troubleshoot in the left sidebar on the following screen.
   
2. On the right pane, select Additional troubleshooters.

1. Select Power and then select Run the troubleshooter.

1. Allow the troubleshooter to detect and fix power issues with your PC.

Install Windows 10 Updates

Last but certainly not least, ensure you’re running the latest version of Windows 10. Older Windows versions are known to cause issues, and your issue might be related to running an older Windows version.

Luckily, Windows 10 makes it easy to update your PC. As long as you have an active internet connection, you’re just a few clicks away from installing the latest Windows update on your computer.

1. Open the Settings app by pressing Windows + I keys simultaneously.
2. Select Update & Security on the Settings window.
3. From the left sidebar, select Windows Update.
4. Select Check for updates on the right pane.

1. Reboot your PC and see if sleep mode works as it should.
