首先尝试这些快速修复

It’s best to kick things off by working through the quick fixes below. You might be dealing with a trivial issue that doesn’t require advanced troubleshooting.

  • 重启你的电脑: Usually, restarting your computer is all it takes to resolve problems in Windows. Save your work and select Start 开始 > 功率 > 重新启动 to perform a system reboot.
  • Turn Your Mouse Off & On: Likewise, it’s a good idea to restart the device firmware of the Bluetooth mouse. Locate the 功率 switch on the Bluetooth mouse and set it to 关闭， 然后 On.
  • Move Your Mouse Closer: Bluetooth devices don’t function well at a distance. Reduce the gap between your computer and mouse if you use them far apart. 
  • Eliminate Bluetooth Interference: Make sure that there are no sources of Bluetooth interference (e.g., usually other wireless devices) nearby or between your computer and mouse.
  • 为鼠标充电: A mouse with little charge remaining can weaken its Bluetooth signal. Connect your mouse to a USB port to recharge it or insert fresh batteries.
  • Switch to Another Surface: Avoid smooth surfaces to improve cursor control. 

运行蓝牙疑难解答

Windows 11 comes with a built-in Bluetooth troubleshooter that can automatically detect and fix connectivity issues with Bluetooth devices. To run it:

1。 打开 Start 开始 菜单，然后选择 个人设置.

2. 向下滚动 系统 settings and select the option labeled 疑难解答.

3。 选择 其他疑难解答.

4. 向下滚动并选择 运行 按钮旁边 蓝牙. 

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—罗技选项, Razer Synapse, etc. Look up the Bluetooth mouse model online and install any applicable software from the manufacturer.

If you’ve already done that, update the software (visit the application’s settings page and look for a 检查更新 option or something similar) and see if that eliminates the lag.

Disable Power Management for Bluetooth Adapter

If your Bluetooth mouse lags when left idle for a few seconds, use the Device Manager in Windows 11 to disable power management for the PC’s Bluetooth module.

1.右键单击 Start 开始 按钮并选择 装置经理.

2.展开 蓝牙 category, right-click the Bluetooth module—e.g., Intel(R) Wireless Bluetooth(R)—并选择 查看房源.

3。 切换到 电源管理 选项卡并取消选中旁边的框 Allow the computer to turn off the device to save power。 然后，选择 OK.

If that fails to resolve the issue, expand the 人机接口设备 category (further down the Device Manager) and open the 查看房源 pane for Bluetooth Low Energy GATT compliant HID. 然后，切换到 电源管理 tab and clear the box next to Allow the computer to turn off the device to save power.

Disable Bluetooth Power Management by Modifying Registry Keys

If the above fix doesn’t help, you must modify a set of registry keys related to Bluetooth power management via the Windows 11 Registry Editor. However, since accidental changes can break the operating system, we recommend backing up the system registry 之前进行。

1。 按 Windows + R to open the Run box. Then, type 注册表编辑器 并按下 输入.

2. Navigate to the following folder on the Registry Editor’s left pane:

HKEY_LOCAL_MACHINE > 系统 > CURRENTCONTROLSET > 枚举 > USB

Next, expand the folder that begins with VID_8087 （例如， VID_8087&PID_0026) and then the sub-folder with the numbers and letters (e.g., 5&ed1e05a&0&10). Finally, select 设备参数.

3. Double-click each of the following keys on the right side of the Registry Editor window, add a hexadecimal value of 0，然后选择 OK.

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

备注: If any of the keys above appear missing, right-click a vacant area and select 全新 > DWORD（32位）值. Then, name it as the absent key and save it with a hexadecimal value of 0.

Switch Performance Plan

Another way to avoid Bluetooth mouse lag caused by PC power management is to configure your Windows 11’s default power mode for best performance. However, that can hurt the battery life of laptop devices.

1。 打开 Start 开始 菜单 并选择 个人设置.

2. Select the category labeled 电源和电池.

3.打开旁边的下拉菜单 电源模式 并选择 最佳的性能.

Remove and Reconnect Bluetooth Mouse

The following fix involves removing and reconnecting your Bluetooth mouse or trackpad. That should help eliminate issues with a corrupt Bluetooth device configuration.

1。 打开 “开始”菜单 并选择 个人设置.

2。 选择 蓝牙和设备 on the Settings sidebar. 

3。 选择 更多 icon (three dots) next to your Bluetooth mouse and select 删除设备 > 有.

4。 选择 添加设备.

5。 选择 蓝牙 and repeat the pairing process to re-establish the Bluetooth connection between your mouse and computer.

Check for Bluetooth Driver Updates

If the mouse lag problem persists, download the latest Bluetooth drivers from your PC manufacturer—戴尔, HP, 宏碁, etc. Then, run the setup file within the downloaded package or perform the update via the Device Manager.

1。 打开 装置经理.

2.展开 蓝牙 类别。

3. Right-click the Bluetooth module and select 更新驱动程序.

4。 选择 Browser my computer for drivers.

5。 选择 浏览 and locate the downloaded driver package on your computer. Then, select 下一页 执行更新。

Uninstall and Reinstall Bluetooth Drivers

If you can’t find newer updates, try removing and reinstalling the Bluetooth driver for your PC. Make sure to use a wired mouse to interact with the GUI in the meantime.

1。 打开 装置经理.

2.展开 蓝牙 类别。

3. Right-click the Bluetooth module and select 卸载设备.

4. 选中旁边的框 尝试删除此设备的驱动程序 并选择 卸载.

5. Restart your computer. Windows 11 will automatically reinstall the Bluetooth driver at startup. If it doesn’t, re-open the 装置经理 并选择 操作 > 扫描硬件更改.

更新图形驱动程序

Outdated video drivers can also result in a laggy mouse pointer. Check the card manufacturer’s website (NVIDIA公司, AMD公司, 英特尔, etc.) for possible updates. Alternatively, use a third-party driver updater tool or Windows Update to acquire the latest video drivers for your PC (more on that next).

更新Windows 11

If the Bluetooth mouse lag persists, try updating Windows 11 to its latest version. That should patch out any known issues in the operating system that prevent Bluetooth devices from functioning correctly.

1。 打开 “开始”菜单 并选择 个人设置.

2。 选择 Windows更新 on the Settings sidebar.

3。 选择 检查更新.

4。 选择 立即下载 安装可用的更新。

Additionally, select 高级选项 > 可选更新 and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

扫描恶意软件

Computer viruses are another reason that induces mouse or touchpad lag. Use the built-in Windows安全 tool (accessible via the system tray) or a dedicated anti-malware utility-例如 的Malwarebytes—to thoroughly scan your PC for malware.

禁用快速启动

Next up, consider disabling Fast Startup in Windows 11. It helps boot up your PC faster and has a history of causing problems with input devices.

1。 打开 Start 开始 菜单，类型 控制面板，然后按 输入.

2。 选择 硬件和声音.

3。 在下面 电源选项 部分，选择 选择的电源按钮做什么.

4。 选择 更改当前不可用的设置.

5. 取消选中旁边的框 打开快速启动（推荐） and select Save changes.

你还能做什么？

If none of the fixes above work, here are a few other things to try:

  • Use the Bluetooth mouse as a standard wireless mouse. Logitech mice, such as the Logitech MX Master, come with a unifying receiver that offers better connectivity than Bluetooth. 
  • Run an SFC or a DISM scan to resolve underlying problems with your Windows 11 PC. 
  • Pair and use the Bluetooth mouse on another computer (PC or Mac). If the mouse lag issue persists, you’re likely dealing with a defective device—send it back for a replacement if it’s still under warranty. If not, continue troubleshooting your PC in Safe Mode.
