When Bluetooth shows that it is paired but not connected, you can try the following fix: 1. Check and start the Bluetooth Support Service service; 2. Click the "Connect" button manually to complete the connection; 3. Update or reinstall the Bluetooth driver; 4. Make sure the device is not connected to other hosts at the same time; 5. Repair the device after deleting the device to clear configuration errors. In most cases, the problem can be solved through the above steps without the need to replace the device.

Bluetooth shows that it is paired but not connected, which is quite common on Windows computers. Especially when you want to use Bluetooth headsets, speakers or mouse, you suddenly find that although the device shows "paired", it just can't connect, the sound does not respond, and the device does not work. This problem is usually not that the hardware is broken, but that there is a small problem in the system setup or connection process.

The following common reasons and solutions can help you quickly troubleshoot and fix the "paired but not connected" problem of Bluetooth.

1. Check whether the Bluetooth service is running normally

Sometimes the Bluetooth function seems to be on, but in fact the service in the background may be stopped. This situation will cause the device to be searched and paired, but it just can't be connected.

Operation steps:

• Press Win R to open the run window and enter services.msc to enter.
• Find the Bluetooth Support Service in the list.
• Confirm that its status is "Running". If not, right-click and select "Start".
• Also check whether its startup type is "automatic", so that there will be no problems when the next startup is started.

If this service is not installed, it may be because the system components are missing. It is recommended to use system file scanning tools (such as sfc /scannow ) to repair it.

2. The device is not correctly set to "Connected"

Sometimes, even if the pairing is successful, you still need to "connect" manually once. For example, Bluetooth headsets display "Paired" in Windows, but you have to click "Connect" to actually use it.

How to operate:

• Open Settings → Devices → Bluetooth and Other Devices.
• Find your device and click on it.
• If you see the "Connect" button instead of "Disconnect", it means that you haven't really connected yet.
• Click "Connection" and wait a few seconds to see if there is any prompt to be successful.

Some devices require you to "reconnect" in the Bluetooth menu, or unplug/reboot and try again.

3. Update or reinstall Bluetooth drivers

The Bluetooth module relies on the driver to work properly. If the driver is outdated, damaged, or incompatible, the connection will fail.

The solution is as follows:

• Press Win X and select Device Manager.
• Expand the Bluetooth column.
• Right-click on your Bluetooth adapter and select "Update Driver".
• If the update is invalid, you can try "Uninstall the device", then restart the computer, and let the system automatically reinstall the driver.

If you are not sure about the specific model, you can go to the official website of the motherboard or laptop brand to download the latest Bluetooth driver, such as the official support page of Intel, Realtek or Broadcom.

4. Check whether the device is connected to other devices at the same time

Bluetooth devices can usually only connect to one host at the same time. For example, if your headset is still connected to your phone, it is likely that Windows will not be able to connect.

Handling suggestions:

• Turn off Bluetooth on other devices, or “disconnect” the current connection from there.
• Then go back to Windows and try to connect again.
• Some devices will automatically reconnect to the recently used host, so you can also try turning off Bluetooth and turn it on.

5. Reset Bluetooth device information

If none of the above works, try to delete the device thoroughly and re-pair it.

Operation steps:

• Go to Settings → Devices → Bluetooth and Other Devices.
• Find the problem device and click to enter the details page.
• Select Delete Device.
• Then turn off and turn on Bluetooth, search again and pair.

This method can clear some hidden configuration errors, especially for problems that occur after long-term use.

Basically these common troubleshooting methods. Bluetooth problems are often not a big problem, but just a small misunderstanding between the system or device. You can solve it by restarting and re-pairing. When encountering similar situations, don’t rush to change the equipment. Follow the above steps step by step, most of them can be solved.
