如果您的Windows计算机从睡眠模式唤醒后仍然黑屏，那么这篇文章中的一些建议肯定会对您有所帮助。一些用户报告说，在将计算机从睡眠模式唤醒后，他们的计算机屏幕没有打开。如果您在Windows 11/10 台式计算机上遇到此问题，您应该做的第一件事是关闭^(Off)并再次打开显示器。这个技巧对一些受影响的用户有效。

^(Screen)从睡眠模式唤醒电脑后^{(Sleep Mode)}屏幕一直黑屏

如果在将 Windows 计算机从睡眠模式唤醒后，^{(Sleep Mode)}显示器^(Monitor)屏幕保持黑色，您需要查看以下内容：

1. 检查是否允许设备唤醒计算机。
2. 运行电源疑难解答。
3. 关闭快速启动。
4. 回滚显示驱动程序。
5. 卸载并重新安装显示驱动程序。
6. 更新您的系统 BIOS。
7. 运行黑屏疑难解答。

1]检查^(Check)您的设备是否允许唤醒计算机

有时问题并没有我们想象的那么复杂。我们用来将计算机从睡眠模式唤醒的设备（键盘、鼠标等）应该有权这样做。默认情况下，为设备启用此设置。但是，如果您遇到此问题，则应检查此设置。

这样做的步骤如下：

1. 右键单击^{(Right-click)}“开始^(Start)”图标或直接按键盘上的Win + X键。
2. 单击设备管理器^{(Device Manager)}以启动它。
3. 在设备管理器中，找到鼠标和其他指针设备^{(Mice and other pointing devices)}节点。找到它后，单击旁边的箭头图标将其展开。
4. 现在，选择您的鼠标并右键单击它。选择属性^(Properties)。
5. 单击电源管理^{(Power Management)}选项卡。
6. 在那里，您会找到一个选项允许此设备唤醒计算机^{(Allow this device to wake the computer)}。如果默认情况下未启用该选项，请单击它旁边的复选框。单击确定^{(Click OK)}以保存更改。

为键盘启用该功能的步骤是相同的​​，除了您必须展开键盘^(Keyboards)节点而不是鼠标^(Mice)和其他指针设备节点的第三步。

现在，让您的计算机进入睡眠状态并检查您是否能够使用鼠标或键盘将其唤醒。

2]运行电源故障排除程序

有时，计算机电源设置中的问题可能会导致此类问题。如果您的计算机出现这种情况，运行电源故障排除^{(Power Troubleshooter)}程序可能会有所帮助。

下面列出了运行电源疑难解答的步骤：^(Power)

1. 启动设置^(Settings)应用程序。
2. 单击更新和安全^{(Update & Security)}选项。
3. 现在，单击左侧的疑难解答。^{(Troubleshoot)}

5. 单击电源^(Power)。您可能需要向下滚动“其他疑难解答^{(Troubleshooters)}”列表才能找到它。
6. 现在，单击运行疑难解答^{(Run the troubleshooter)}按钮。

等到^(Wait)故障排除过程完成。它将解决与计算机电源设置相关的所有问题。

4]回滚显示驱动程序

您也可以尝试回滚显示驱动程序。回滚^(Rolling)驱动程序会卸载当前更新的版本并安装以前的版本。如果您在某个更新后遇到问题，此方法很有用。

请按照下列步骤操作：

1. 启动设备管理器^{(Device Manager)}。
2. 双击显示适配器^{(Display adapters)}节点以展开它。
3. 右键单击您的显示^(Display)驱动程序并选择Properties。
4. 单击驱动程序^(Driver)选项卡。

Screen stays black after waking computer from Sleep Mode

If your Windows computer screen stays black after waking it from sleep mode, then some of the suggestions in this post аre sure to hеlp you. Some users hаve reported that their computer screen did not turn on after waking the computer from sleep mode. If you get this issυe on your Wіndows 11/10 deѕktop computer, the first thing that you should do is turn your monitor Off and On it again. This triсk has worked for some аffected users.

Screen stays black after waking computer from Sleep Mode

If your Monitor screen stays black after waking your Windows computer from Sleep Mode, here are the things you need to take a look at:

1. Check whether the device is allowed to wake the computer or not.
2. Run Power Troubleshooter.
3. Turn Off Fast Startup.
4. Rollback the display driver.
5. Uninstall and reinstall the display driver.
6. Update your system BIOS.
7. Run Black Screen Troubleshooter.

1] Check whether your device is allowed to wake the computer or not

Sometimes the issue is not as complicated as we think. The device (keyboard, mouse, etc.) that we use to wake the computer from sleep mode should have permission to do so. By default, this setting is enabled for the devices. But if you are getting this issue, you should check this setting.

The steps to do so are as follows:

1. Right-click on the Start icon or simply press Win + X keys on your keyboard.
2. Click on the Device Manager to launch it.
3. In the Device Manager, locate the Mice and other pointing devices node. Once you find it, expand it by clicking on the arrow icon adjacent to it.
4. Now, select your mouse and right-click on it. Select Properties.
5. Click on the Power Management tab.
6. There, you will find an option saying Allow this device to wake the computer. If the option is not enabled by default, click on the checkbox adjacent to it. Click OK to save the changes.

The steps to enable the feature for the keyboard are the same except the third step in which you have to expand the Keyboards node instead of Mice and other pointing devices node.

Now, put your computer to sleep and check if you are able to wake it by using your mouse or keyboard or not.

6. Now, click on the Run the troubleshooter button.

Wait till the troubleshooting process gets completed. It will fix all the issues associated with your computer’s power settings.

You can also try to roll back your display driver. Rolling back a driver uninstalls the current updated version and installs the previous version. This method is useful in case you are getting the problem after a certain update.

Follow the steps listed below:

1. Launch the Device Manager.
2. Double-click on the Display adapters node to expand it.
3. Right-click on your Display driver and select Properties.
4. Click on the Driver tab.
5. Click on the Roll Back Driver if the option is available.

Now, check whether the issue is fixed or not.

You may press WinKey+Ctrl+Shift+B keyboard shortcuts to restart your Display driver and see if that helps.

The steps written below will guide you on how to do this:

1. Launch Device Manager.
2. Expand the Display drivers node and right-click on your display driver. Select the Uninstall device option.
