如果您的计算机自动从睡眠中唤醒^{(computer is waking up from Sleep automatically)}，则可能启用了 允许唤醒计时器^{(Allow wake timers)}选项。如果您想在Windows 11^{(Windows 11)}或Windows 10上禁用或关闭允许^(Allow)唤醒计时器，这里有一个很有帮助的分步指南。

即使您将计算机置于睡眠^(Sleep)模式，它也可能会唤醒以执行您之前设置的计划任务。同样，如果将更新设置为在预定义的时间安装，则 允许唤醒计时器^{(Allow wake timers)} 功能可以自动唤醒您的系统。此功能包含在电源选项^{(Power Options)}中，您可以根据需要打开或关闭它。

什么是Windows 11或 Windows 10中的允许^(Allow)唤醒计时器

有时，我们安排在预定义时间执行任务，或者Windows设置特定时间以自动安装挂起的更新。假设某项任务设置为在下午 6 点执行，但您在下午 5:55 将计算机置于睡眠模式。您的Windows PC 将在下午 6 点自动唤醒以在这种情况下执行任务。发生这种情况是因为允许唤醒计时器^{(Allow wake timers)}功能。

但是，如果您不希望您的Windows PC 使用“允许^(Allow)唤醒计时器”选项，您可以通过以下方式停止它。在执行这些步骤之前，您应该知道，如果您使用的是笔记本电脑，则需要在两个不同的位置更改相同的设置两次。由于笔记本电脑主要有两种模式（插入和使用电池），因此需要更改设置两次。

如何在 Windows 11/10 上禁用允许唤醒计时器^(Allow)

要在Windows 11^{(Windows 11)}或Windows 10上启用或禁用允许唤醒计时器，请按照以下步骤操作 -

1. 在任务栏^(Taskbar)搜索框中搜索编辑电源计划。
2. 单击单个结果。
3. 单击更改高级电源^{(Change advanced power)}设置选项。
4. 选择您正在使用的电源计划。
5. 展开睡眠^(Sleep)设置。
6. 展开允许唤醒计时器^{(Allow wake timers)}选项。
7. 单击On battery和Plugged in的^{(Plugged in)}Enable选项。
8. 选择禁用^(Disable)选项。
9. 单击确定^(OK)按钮。

在任务栏^(Taskbar)搜索框中搜索“编辑电源计划”，然后单击单个结果。它会在您的屏幕上打开“编辑计划设置” ^{(Edit Plan Settings )}窗口。之后，单击 更改高级电源设置 ^{(Change advanced power settings )}选项，然后从下拉列表中选择您正在使用的电源计划。

现在，展开 睡眠 ^(Sleep )菜单并单击 允许唤醒计时器^{(Allow wake timers)} 选项。如果您使用的是笔记本电脑，您可以找到两个选项 - 使用 电池^{(On battery)} 和 插入电源^{(Plugged in)}；如果您使用的是台式计算机，则可以找到 Settings。

无论哪种方式，单击相应的 Enable 选项并选择 Disable 选项以打开 Allow wake timers。

如前所述， 如果您使用的是 Windows 笔记本电脑，则必须对On battery 和 Plugged执行相同的操作。^{(Plugged in)}

最后，单击“确定 ^(OK )”按钮保存更改。

希望本指南有所帮助。

How to Enable or Disable Allow wake timers on Windows 11/10

If your computer is waking up from Sleep automatically, there is a chance that the Allow wake timers option is enabled. If you want to disable or turn off Allow wake timers on Windows 11 or Windows 10, here is a step-by-step guide that will be helpful.

Even if you put your computer on Sleep mode, it may wake up to perform a scheduled task that you set earlier. Similarly, if an update was set to be installed at a predefined time, the Allow wake timers functionality could wake your system up automatically. This functionality is included in the Power Options, and you can turn it on or off according to your requirements.

What is Allow wake timers in Windows 11 or Windows 10

At times, we schedule a task to be performed at a predefined time, or Windows sets a particular time to install pending updates automatically. Let’s say that a task is set to be performed at 6 PM, but you put your computer on Sleep mode at 5:55 PM. Your Windows PC will wake itself up automatically at 6 PM to perform the task in that situation. It happens because of the Allow wake timers feature.

However, if you do not want your Windows PC to utilize the Allow wake timers option, here is how you can stop it. Before heading to the steps, you should know that you are required to change the same setting twice in two different locations if you are using a laptop computer. As laptop computers have mainly two modes (plugged in and on battery), it is required to change the setting twice.

How to disable Allow wake timers on Windows 11/10

To enable or disable Allow wake timers on Windows 11 or Windows 10, follow these steps-

1. Search for edit power plan in the Taskbar search box.
2. Click on the individual result.
3. Click on the Change advanced power settings option.
4. Choose a power plan that you are using.
5. Expand the Sleep settings.
6. Expand Allow wake timers option.
7. Click on Enable option for On battery and Plugged in.
8. Select the Disable option.
9. Click the OK button.

Search for the “edit power plan” in the Taskbar search box and click on the individual result. It opens the Edit Plan Settings window on your screen. After that, click on the Change advanced power settings option and choose the power plan you are using from the drop-down list.

Now, expand the Sleep menu and click on the Allow wake timers option. If you are using a laptop computer, you can find two options – On battery and Plugged in; if you are using a desktop computer, you can find Settings.

Either way, click on the corresponding Enable option and choose the Disable option to turn on Allow wake timers.

As mentioned earlier, you must do the same for On battery and Plugged in if you are using a Windows laptop.

Finally, click the OK button to save the change.

Hope this guide helped.
