更改关闭笔记本电脑盖时发生的情况(Laptop Lid)
为了在您合上笔记本电脑的盖子时让您的 PC 不进入睡眠状态，您必须调整 Windows 11/10 PC 的电源设置，使其保持清醒状态。为此，您必须通过控制面板访问(Control Panel)电源选项(Power Options)管理控制台。
1. 打开开始菜单(Start menu)，键入控制面板(Control Panel)，然后选择打开(Open)。

4.在“电源选项(Power Options)”窗口的左侧选择选择关闭盖子的功能。(Choose what closing the lid does )
5. 使用当我合上盖子(When I close the lid)部分旁边的下拉菜单来确定您的笔记本电脑在合上盖子时的行为。对于On battery和Plugged in，默认首选项设置为Sleep / Hibernate。要让它保持清醒，请将其更改为Do nothing。
警告(Warning)：将您的笔记本电脑配置为在使用电池供电时保持唤醒可能会导致意外的热损坏——例如，如果您在设备仍在运行时将其放入包中。我们建议您仅将“已插入”列的盖子首选项更改为“(Plugged in)不执行任何操作(Do nothing)” 。
6. 选择保存更改(Save changes)按钮以应用您的更改。
您现在可以关闭笔记本电脑并通过外接显示器、键盘和鼠标继续使用操作系统。如果您想将您的盖子偏好更改回原来的样子，请重复上述步骤并从Do nothing切换到Sleep / Hibernate。

How to Keep Your Monitor On When Laptop is Closed in Windows 11/10
Even if you have an external monitor, running a Windows 11/10 lаptop with its lid closed might force the PC to go to sleep. Here’s how to stop that.
If you’ve hooked up an external monitor to your laptop, you might prefer closing the laptop’s lid and maybe placing the device on a vertical stand to free up desk space. Sadly, the default power options in Windows prevent you from doing that. Shut the lid, and you trigger sleep mode.
In this article, you will learn how to keep your Windows 11 or 10 laptop on even with the lid closed by re-configuring the power button and lid settings. You will also learn how to troubleshoot your computer if closing its lid continues to put it to sleep despite having your preferences set up correctly.

Change What Happens When You Close the Laptop Lid
To keep your PC from sleeping when you close the lid on your laptop, you must tweak the power settings for your Windows 11/10 PC, so it stays awake. For that, you must access the Power Options management console via the Control Panel.
1. Open the Start menu, type Control Panel, and select Open.
2. Select the category labeled Hardware and Sound.
3. Select Power Options.
Note: On a Windows 10 laptop, you can access the screen that follows by right-clicking the Battery icon on the system tray (right-corner of the taskbar) and selecting Power Options.
4. Select Choose what closing the lid does on the left side of the Power Options window.
5. Use the drop-down menus next to the When I close the lid section to determine how your laptop behaves when you close its lid. The default preferences are set to Sleep/Hibernate for both On battery and Plugged in. To make it stay awake, change that to Do nothing.
Warning: Configuring your laptop to stay awake while on battery power can cause accidental heat damage—e.g., if you put the device into a bag while it’s still running. We recommend that you only change the lid preferences to Do nothing for the Plugged in column.
6. Select the Save changes button to apply your changes.
You can now close your laptop and continue using the operating system via an external display, keyboard, and mouse. If you want to change your lid preferences back to how they were, repeat the steps above and switch from Do nothing to Sleep/Hibernate.
Closing Lid Still Forces Laptop to Sleep? Try These 7 Fixes
If closing the lid of your laptop still causes the operating system to go to sleep despite modifying the device’s power button and lid preferences, restart the device. If that doesn’t help, here are several fixes that you can work your way through to resolve the issue.
1. Reset Power Settings to Defaults
It’s best to begin by reverting the power plan for your laptop to its default settings. That should resolve conflicting or broken configurations preventing it from applying your lid preferences.
1. Open the Power Options window and select Change plan settings next to the active power plan.
2. Select Restore default settings for this plan.
3. Select Yes to confirm.
You must then head back to the previous screen, select Choose what closing the lid does, and re-configure the lid settings to keep your laptop running with its lid closed. If the issue persists, try creating a new power plan.
2. Run the Power Troubleshooter
Both Windows 11 and 10 come with a built-in troubleshooter that can detect and resolve issues with conflicting power management settings. Run it and check if that makes a difference.
1. Open the Start menu, type Troubleshoot settings and select Open.
2. Select Other troubleshooters.
3. Select Run next to Power.
3. Disable Fast Startup
Fast Startup speeds up your laptop when you turn it on, but it can also create conflicts with power management. Disable the feature and check if that makes a difference.
1. Open the Power Options window and select Choose what the power buttons do.
2. Select Change settings that are currently unavailable.
3. Scroll down and uncheck the box next to Turn on fast startup (recommended) > Save changes.
4. Reinstall Battery Driver
If the issue persists but only while attempting to use the laptop closed on battery power, use the Device Manager to reinstall the battery driver. Disconnect the power adapter before you begin.
1. Right-click the Start button and select Device Manager.
2. Expand Batteries and select Microsoft ACPI-Compliant Control Method Battery.
3. Select Action > Uninstall device on the menu bar.
4. Select Uninstall.
5. Shut down your laptop. Then, reconnect the device to a power source and reboot it. The operating system will automatically reinstall the battery driver during startup.
5. Update Windows
The following fix involves checking for and applying any pending operating system updates.
1. Open the Start menu and select Settings.
2. Select Windows Update.
3. Select Check for updates.
If Windows Update detects any updates, select Download and Install to install them. Also, select Advanced options > Optional updates and install any hardware-related updates if available.
6. Run SFC and DISM
If your laptop continues to go to sleep when you close its lid, run the System File Checker and Deployment Image Servicing and Management command-line tools next.
1. Right-click the Start button and select Windows Terminal (Admin) or Windows PowerShell (Admin).
2. Run the following command:
sfc /scannow
3. Run the following command next:
DISM /Online /Cleanup-Image /RestoreHealth
7. Update Laptop Drivers
Updating the drivers for your laptop could also resolve firmware-related issues preventing you from using the device with its screen closed. Check the laptop manufacturer’s site—Dell, HP, Lenovo, etc.—for the latest drivers. Additionally, you might consider updating the BIOS or UEFI for your laptop.
