Bluetooth gives you the freedom to move without a tether, but it isn’t always the most reliable way to use wireless devices. If you’re having trouble with Bluetooth on your Windows machine, you can follow the steps below to troubleshoot it.

藍牙使您可以不受束縛地自由移動，但這并不總是使用無線設備的最可靠方法。 如果Windows機器上的藍牙出現問題，可以按照以下步驟進行故障排除。

藍牙基本故障排除步驟 (Basic Bluetooth Troubleshooting Steps)

While many of these steps might seem obvious, they will fix many of the most common Bluetooth issues on Windows.

盡管這些步驟中的許多步驟似乎很明顯，但它們將解決Windows上許多最常見的藍牙問題。

檢查藍牙是否打開 (Check That Bluetooth Is Turned On)

Start by making sure?Bluetooth is actually enabled on your Windows PC. Just because the symbol is in the taskbar doesn’t mean your Bluetooth radio is actually turned on.

首先，請確保Windows PC上實際啟用了藍牙。 僅僅因為該符號位于任務欄中并不意味著您的藍牙無線電實際上已經打開。

To check it, click the Windows notification icon on your taskbar in the bottom-right corner of your screen. If you don’t see a “Bluetooth” tile, click the “Expand” button. If the “Bluetooth” tile is grayed-out, your Bluetooth radio is turned off.

要檢查它，請單擊屏幕右下角任務欄上的Windows通知圖標。 如果沒有看到“藍牙”圖塊，請單擊“擴展”按鈕。 如果“藍牙”圖塊變灰，則表明您的藍牙無線電已關閉。

Click it to turn it back on—the tile will turn blue to show the change.

單擊它可以將其重新打開-磁貼將變為藍色以顯示更改。

You can also head to Settings > Devices > Bluetooth and Other Devices and toggle the “Bluetooth” switch until it turns blue.

您也可以轉到“設置”>“設備”>“藍牙和其他設備”，然后切換“藍牙”開關，直到變成藍色。

重新啟動您的藍牙收音機 (Restart Your Bluetooth Radio)

If Bluetooth is enabled, switching it off and on again might resolve some underlying issues of which you’re unaware.

如果啟用了藍牙，則將其關閉然后再打開可能會解決一些您不知道的潛在問題。

To do this, click the notification icon in your Windows taskbar to access your quick settings. Click the “Bluetooth” tile to turn it off. Once it goes gray, click it again to turn it back on.

為此，請單擊Windows任務欄中的通知圖標以訪問您的快速設置。 單擊“藍牙”圖塊將其關閉。 變灰后，再次單擊以將其重新打開。

When the tile turns blue, your Bluetooth radio is back on, and ready to use.

當圖塊變成藍色時，您的藍牙無線電已重新打開，可以使用了。

檢查電池 (Check the Battery)

If you aren’t keeping track of the battery level on your Bluetooth device, you might not even be aware when it runs out of power.

如果您不跟蹤藍牙設備上的電池電量，那么當它電量耗盡時，您甚至可能都不知道。

Before you try a more serious solution, you might want to replace the batteries in your Bluetooth device or charge it, and then try it again.

在嘗試更嚴格的解決方案之前，您可能需要更換藍牙設備中的電池或對其進行充電，然后再次嘗試。

重新啟動電腦 (Restart Your PC)

The best fixes are sometimes the easiest, and if you haven’t tried it already, give your PC a quick restart.

最好的修復程序有時是最簡單的，并且，如果您尚未嘗試過，請快速重啟PC。

When you reboot your PC, you wipe the slate clean, and clear out any idle processes or memory leaks. It’s not a miracle fix, but it can rectify some issues with the hardware, so give it a go.

重新啟動PC時，將板擦干凈，并清除所有空閑進程或內存泄漏。 這不是一個奇跡修復程序，但是它可以糾正硬件方面的一些問題，因此，請放手一搏。

檢查藍牙干擾和設備距離 (Check Bluetooth Interference and Device Distance)

Bluetooth devices communicate wirelessly via radio waves. Just like a Wi-Fi network, interference can affect Bluetooth connections. Other radio signals, physical obstacles (like thick walls), and devices like microwaves can all block or degrade a Bluetooth connection.

藍牙設備通過無線電波進行無線通信。 就像Wi-Fi網絡一樣，干擾會影響藍牙連接。 其他無線電信號，物理障礙物(如厚壁的墻壁)以及諸如微波之類的設備都會阻塞或降低藍牙連接。

Take a moment to survey the area. How far away is your Bluetooth device from your PC? The bigger the distance, the weaker the signal.

花一點時間調查一下該地區。 藍牙設備與PC距離多遠？ 距離越大，信號越弱。

Move your device closer to your PC and see if it impacts the Bluetooth connectivity. If not, try (if possible) to use your Bluetooth device in another location. You can also use third-party apps, like the?Bennett Bluetooth Monitor, to check your Bluetooth’s signal strength.

將設備移近PC，看看它是否影響藍牙連接。 如果沒有，請嘗試(如果可能)在其他位置使用您的藍牙設備。 您還可以使用Bennett Bluetooth Monitor等第三方應用程序來檢查Bluetooth的信號強度。

If the problem persists, interference might not be the problem. But there are some other potential fixes.

如果問題仍然存在，則可能不是問題所在。 但是還有其他一些潛在的解決方法。

安裝或更新藍牙設備驅動程序 (Install or Update Bluetooth Device Drivers)

Windows 10 automatically installs drivers for devices that connect to it, but only when those drivers are available on your PC or through Windows Update. In most cases, though, Bluetooth devices (especially keyboards and mice) should work fine right out of the box.

Windows 10會自動為與其連接的設備安裝驅動程序，但前提是您的PC上或通過Windows Update有可用的驅動程序。 不過，在大多數情況下，Bluetooth設備(尤其是鍵盤和鼠標)應該可以立即使用。

If Windows can’t find the correct drivers for your Bluetooth device, however, it won’t work. If this happens, check the device manufacturer’s website to see if it offers a driver for your device. If so, download and install it, and that should resolve the problem.

但是，如果Windows找不到適合您的藍牙設備的正確驅動程序，它將無法正常工作。 如果發生這種情況，請檢查設備制造商的網站以查看它是否為您的設備提供了驅動程序。 如果是這樣，請下載并安裝它，這應該可以解決問題。

This also applies to the Bluetooth radio itself. If the drivers for your Bluetooth chipset aren’t installed automatically, Bluetooth won’t work on your PC. Visit the PC manufacturer’s website or, if you built the PC yourself, check the motherboard manufacturer’s website for supported drivers.

這也適用于藍牙無線電本身。 如果未自動安裝用于藍牙芯片組的驅動程序，則藍牙將無法在您的PC上運行。 訪問PC制造商的網站，或者，如果您自己構建PC，請訪問主板制造商的網站以獲取受支持的驅動程序。

You might also find that a new Windows update has impacted your device, requiring updated drivers. In most cases, Windows will look for and install updated drivers automatically. If it doesn’t, though, visit the device manufacturer’s website and install the latest drivers.

您可能還會發現，新的Windows更新已影響您的設備，需要更新的驅動程序。 在大多數情況下，Windows會自動查找并安裝更新的驅動程序。 如果沒有，請訪問設備制造商的網站并安裝最新的驅動程序。

To see whether your Bluetooth device is installed, you have to check the Windows Device Manager. To do this, right-click the Windows Start button and click “Device Manager.”

要查看您的藍牙設備是否已安裝，您必須檢查Windows設備管理器。 為此，請右鍵單擊Windows“開始”按鈕，然后單擊“設備管理器”。

If your Bluetooth device is recognized, it appears under the category relevant to its purpose. For example, a Bluetooth radio would be under the “Bluetooth” category. If the device isn’t recognized, it will be listed under the “Other Devices” category.

如果您的藍牙設備被識別，它將顯示在與其用途相關的類別下。 例如，藍牙無線電將在“藍牙”類別下。 如果無法識別該設備，它將列在“其他設備”類別下。

When you find it, right-click the device, and then click “Update Driver” to search for a new driver.

找到它后，右鍵單擊該設備，然后單擊“更新驅動程序”以搜索新的驅動程序。

Click “Search Automatically for Updated Driver Software” if you want to search for a driver automatically.

如果要自動搜索驅動程序，請單擊“自動搜索更新的驅動程序軟件”。

If you downloaded the driver from the manufacturer’s website (and it doesn’t include an automatic installer), click “Browse My Computer for Driver Software” and follow the onscreen instructions.

如果您是從制造商的網站上下載的驅動程序(并且不包含自動安裝程序)，請單擊“瀏覽我的計算機以獲取驅動程序軟件”，然后按照屏幕上的說明進行操作。

If you clicked “Search Automatically for Updated Driver Software,” Windows will tell you if it thinks you already have the best driver for your device. However, you can also search Windows Update for alternatives.

如果單擊“自動搜索更新的驅動程序軟件”，則Windows會告訴您是否認為您已經擁有適用于設備的最佳驅動程序。 但是，您也可以在Windows Update中搜索替代方法。

To do so, just click “Search for Updated Drivers on Windows Update” to proceed.

為此，只需單擊“在Windows Update上搜索更新的驅動程序”以繼續。

This opens Windows Update in Settings.?Click “Check for Updates” to begin a search.

這將在“設置”中打開Windows Update。 單擊“檢查更新”開始搜索。

When (or if) Windows Update finds an updated driver for your device, it will download and install it. When that process is complete, restart your PC, and then try your Bluetooth device again.

當(或如果)Windows Update找到設備的更新驅動程序時，它將下載并安裝它。 該過程完成后，重新啟動PC，然后再次嘗試使用藍牙設備。

刪除并重新配對您的藍牙設備 (Remove and Re-Pair Your Bluetooth Device)

Sometimes,?removing the Bluetooth device from your PC resolves connection issues. You can then?“re-pair” the device?with your PC.

有時，從PC上刪除Bluetooth設備可以解決連接問題。 然后，您可以將設備與PC “重新配對” 。

To start this process, open the Bluetooth settings in Windows. If the Bluetooth icon is visible in the Windows taskbar, right-click it, and then select “Open Settings.”

要開始此過程，請在Windows中打開Bluetooth設置。 如果Windows任務欄中可見藍牙圖標，請右鍵單擊它，然后選擇“打開設置”。

If you don’t see the Bluetooth icon, right-click the Start menu and select “Settings.” From there, click Devices > Bluetooth and Other Devices to access your Bluetooth settings.

如果看不到藍牙圖標，請右鍵單擊“開始”菜單，然后選擇“設置”。 在此處，單擊設備>藍牙和其他設備以訪問您的藍牙設置。

Your known Bluetooth devices will be listed here. Select your device, click “Remove Device,” and then click “Yes” to confirm. This removes the device from your PC.

您的已知藍牙設備將在此處列出。 選擇您的設備，單擊“刪除設備”，然后單擊“是”進行確認。 這將從您的PC中刪除該設備。

When the process is completed, restart your PC.

該過程完成后，重新啟動PC。

After you log back in on your device, head back to the Bluetooth settings. Click “Add Bluetooth or Other Device” at the top. In the “Add a Device” window that appears, click?“Bluetooth.”

重新登錄設備后，回到藍牙設置。 點擊頂部的“添加藍牙或其他設備”。 在出現的“添加設備”窗口中，單擊“藍牙”。

Wait for your PC to detect the device, and then click it to connect. You might need to type a PIN on one or both devices to allow them to pair.

等待您的PC檢測到該設備，然后單擊它進行連接。 您可能需要在一個或兩個設備上鍵入PIN碼才能允許它們配對。

使用Windows 10疑難排解工具 (Use the Windows 10 Troubleshooter)

If all else fails, you can also try the Windows Troubleshooter on Windows 10 and see if it can resolve your Bluetooth issues. It checks your Bluetooth radio and device settings step-by-step, and identifies any issues.

如果其他所有方法均失敗，您也可以在Windows 10上嘗試Windows故障排除程序，看看它是否可以解決藍牙問題。 它會逐步檢查您的藍牙無線電和設備設置，并確定所有問題。

If it detects an issue, it will inform you, and either ask you whether you’d like to fix it or direct you on how you can fix the problem yourself.

如果檢測到問題，它將通知您，并詢問您是否要解決此問題，或指導您如何自己解決問題。

To run Windows Troubleshooter, right-click the Start menu and select “Settings.”

要運行Windows Troubleshooter，請右鍵單擊“開始”菜單，然后選擇“設置”。

From there, go to Update and Security > Troubleshoot > Bluetooth, and then click “Run the Troubleshooter.” Windows will automatically begin working through your Bluetooth status and configuration. If it finds a problem, it’ll direct you to fix it.
