首先嘗試這些快速修復

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.

  • 重啟你的電腦: Usually, restarting your computer is all it takes to resolve problems in Windows. Save your work and select 開始 > 強大能力 > 重新啟動 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 強大能力 switch on the Bluetooth mouse and set it to 關閉，然後 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.
  • 為鼠標充電: 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. 

運行藍牙疑難解答

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

1。 打開 開始 菜單，然後選擇 設定.

2. 向下滾動 系統 settings and select the option labeled 疑難解答.

3。 選擇 其他疑難解答.

4. 向下捲動並選擇 跑 按鈕旁邊 藍牙. 

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—羅技選項, 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 檢查更新 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.右鍵單擊 開始 按鈕，然後選擇 “設備管理器”.

2。 展開 藍牙 category, right-click the Bluetooth module—e.g., Intel(R) Wireless Bluetooth(R)—並選擇 氟化鈉性能.

3。 切換到 電源管理應用 選項卡並取消選取旁邊的框 允許計算機關閉設備以節省電量。 然後，選擇 OK.

If that fails to resolve the issue, expand the 人機接口設備 category (further down the Device Manager) and open the 氟化鈉性能 pane for Bluetooth Low Energy GATT compliant HID. 然後，切換到 電源管理應用 tab and clear the box next to 允許計算機關閉設備以節省電量.

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 之前進行。

1。 按 Windows + R 打開運行框。然後，輸入 註冊表編輯器 並按下 Enter.

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

HKEY_LOCAL_MACHINE > 系統 > CURRENTCONTROLSET > 枚舉 > 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 設備參數.

3. Double-click each of the following keys on the right side of the Registry Editor window, add a hexadecimal value of 0，然後選擇 OK.

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

備註: 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。 打開 開始 目錄 並選擇 設定.

2. Select the category labeled 電源和電池.

3. 打開旁邊的下拉菜單 電源模式 並選擇 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。 打開 Start menü 並選擇 設定.

2。 選擇 藍牙和設備 on the Settings sidebar. 

3。 選擇 更多 icon (three dots) next to your Bluetooth mouse and select 刪除設備 > 是.

4。 選擇 添加設備.

5。 選擇 藍牙 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—戴爾, HP, 宏碁, etc. Then, run the setup file within the downloaded package or perform the update via the Device Manager.

1。 打開 “設備管理器”.

2。 展開 藍牙 類別。

3. Right-click the Bluetooth module and select 更新驅動程序.

4。 選擇 Browser my computer for drivers.

5。 選擇 瀏覽 and locate the downloaded driver package on your computer. Then, select 下一頁 執行更新。

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。 打開 “設備管理器”.

2。 展開 藍牙 類別。

3. Right-click the Bluetooth module and select 卸載設備.

4. 選中旁邊的框 嘗試刪除此設備的驅動程序 並選擇 卸載.

5. Restart your computer. Windows 11 will automatically reinstall the Bluetooth driver at startup. If it doesn’t, re-open the “設備管理器” 並選擇 行動 > 掃描硬件更改.

更新圖形驅動程序

Outdated video drivers can also result in a laggy mouse pointer. Check the card manufacturer’s website (NVIDIA, AMD, Intel英特爾, 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。 打開 Start menü 並選擇 設定.

2。 選擇 Windows更新 on the Settings sidebar.

3。 選擇 檢查更新.

4。 選擇 現在下載 安裝可用的更新。

Additionally, select 高級選項 > 可選更新 and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

掃描惡意軟件

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.

禁用快速啟動

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。 打開 開始 菜單，輸入 控制面板，然後按 Enter.

2。 選擇 硬件和聲音.

3。 在下面 電源選項 部分，選擇 選擇的電源按鈕做什麼.

4。 選擇 更改當前不可用的設置.

5. 取消選取旁邊的方塊 打開快速啟動（推薦） and select Save changes.

你還能做什麼？

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.
