这篇文章将向您展示如何找出是什么将您的Windows 10计算机从睡眠状态唤醒(Sleep)。将我们的 PC 置于睡眠模式(Sleep Mode)是节省能源并确保我们能够快速恢复工作的最佳方法之一。但是，如果 PC 在您将其置于睡眠模式后几乎立即唤醒怎么办？当然，这是一个问题，要找出解决方案，您首先需要了解Windows 10 PC 的唤醒源是什么。
Windows 10 睡眠模式设置
Windows 10 的“睡眠(Sleep)”模式通过将 PC 置于低功耗状态并在不使用时关闭显示器来帮助节约能源。与完全关机或重新启动不同，睡眠(Sleep)模式可帮助用户更快地恢复工作，并准确地从他/她离开的地方继续工作——包括任何打开的应用程序、文档和文件夹。Windows 10 还会自动将计算机系统置于睡眠模式(Windows 10 also puts the computer system into sleep mode automatically)。自动睡眠设置允许用户选择您希望计算机何时进入睡眠状态以及何时应该自动唤醒。
用更简单的术语来解释，当 PC 进入睡眠状态时，它会进入其大部分组件而不是内存被关闭的状态。这使用户可以快速将计算机唤醒到它进入睡眠时的相同状态。
Windows 10 PC的唤醒源可能是什么？
Windows 10 PC的唤醒源背后有不同类型的令人不快的原因：
- 混合模式已激活
- 病毒或恶意软件感染
- 由于来自硬件组件的驱动程序
- 连接到 PC 的外围设备
- 应用程序阻止Windows计算机正确使用睡眠模式
上述只是可能干扰您的 PC 睡眠的几个原因，在这里抓住真正的麻烦制造者至关重要。

为什么我的 Windows 10 电脑会自动唤醒？
您可以通过以下方法找出系统在入睡后意外唤醒的原因：
- 单命令行诊断
- Windows 事件查看器
1]单命令行诊断
此解决方案需要使用命令提示符(Command Prompt)，因为Windows不会在任何图形界面中显示此信息。跟着这些步骤：
1]以管理员身份启动“命令提示符” 。(Command Prompt’)在“开始菜单(Start menu)”中搜索“ cmd”，右键单击该程序，然后点击“以管理员身份运行(Run as administrator)”。
2] 现在，输入命令“ powercfg -lastwake ”并按 Enter 键。
请注意(Please note)– 命令的输出将根据唤醒系统的事件类型而有所不同。
在下面的屏幕截图中，您可以看到问题可归因于USB硬件设备。
其他来源也可能被视为网络活动或预定的唤醒计时器(wake timer)。下面提到的是其他用于发现Windows 10 PC 唤醒源的命令行。
设备查询命令：(Device query command:)
powercfg -devicequery wake_armed
唤醒时间查询命令：(Wake times query command:)
powercfg -waketimers
完成后，此信息将帮助您检测任何意外唤醒的原因。

2]Windows事件查看器
与第一个解决方案一样，这个解决方案也需要使用命令提示符(Command Prompt)打开Windows 事件查看器(Windows Event Viewer)，请按照下列步骤操作：
1]以管理员身份启动“命令提示符”。(Command Prompt)在“开始菜单(Start menu)”中键入“ cmd”，右键单击该程序，然后点击“以管理员身份运行(Run as administrator)”。
2] 现在在命令提示行中键入“ eventvwr.ms ”以打开“ Windows 事件查看器(Windows Event Viewer)”。
3] 在Windows 事件查看器(Windows Event Viewer)中，选择左侧栏中的“ Windows Logs > System”。
4]当您看到显示的日志时，单击右侧栏中出现的“操作”菜单上的“(Actions)过滤当前日志”。(Filter Current Log)
5] 这将打开一个新窗口，允许用户自定义在所选事件日志中显示的内容。
6] 在“过滤当前日志(Filter Current Log)”窗口中，找到“事件源(Event sources)”并从上下文菜单中选择“电源故障排除程序”选项。(Power-Troubleshooter)
您现在将看到按级别、日期和时间以及事件ID(IDs)列出的所有条目。您可以打开单个条目来检查Windows 10 PC 的唤醒源。
突然恢复睡眠的困难在Windows(Windows)设备上很常见，我们希望本指南可以帮助您了解导致问题的确切原因 - 实际上这将使解决问题变得更加容易。如果您在下面的评论部分有任何进一步的疑问，请告诉我们，我们将很乐意解决。

Windows 10 ‘Sleep’ mode helps in conserving energy by putting the PC into a low-power state and turning off the display when it is not in use. Unlike a total shutdown or reboot, Sleep mode helps the user resume work much faster and pick up exactly from where he/she left it – including any application, documents, and folders that were opened. Windows 10 also puts the computer system into sleep mode automatically. Automatic sleep settings allow the user to choose when exactly you want your computer to sleep and when it should automatically wake up.
Explaining in simpler terms, when a PC is put to sleep it enters a state where most of its components are shut off instead of its memory. This lets the user quickly wake the computer back to the same state it was when it went to sleep.

- Due to the drivers from the hardware component
- Peripheral devices connected to your PC
- Application preventing the Windows computer from using the sleep mode properly
Above stated were just a few reasons that could be interfering in your PC’s sleep, catching the actual troublemaker is crucial here.

1] Launch the ‘Command Prompt’ as an administrator. Search for ‘cmd’ in the ‘Start menu’, right-click on the program, and hit ‘Run as administrator’.
2] Now, type the command ‘powercfg -lastwake’ and press the Enter key.
Please note – The output of the command will vary depending on the type of event that woke up the system.
In the screenshot below, you can see that the problem can be attributed to a USB hardware device.
Other sources may also be seen as network activity or a scheduled wake timer. Below mentioned are other command lines to spot the wake source of Windows 10 PC.
Device query command:
powercfg -devicequery wake_armed
Wake times query command:
powercfg -waketimers
Done, this information should help you to detect the causes of any unexpected wakeups.
