The problem of Bluetooth devices on Windows showing "paired but not connected" is usually caused by system or driver exceptions. Solutions include: 1. Restart Bluetooth service and set it to automatically start; 2. Reinsert the Bluetooth adapter or update/reinstall the driver; 3. Re-pair it after deleting the device; 4. Check the device's power and connection status. Following the above steps to check one by one, it can effectively solve most connection problems.

The problem of Bluetooth devices on Windows showing "paired but not connected" is actually quite common. Generally speaking, it is not that the hardware is broken, but that there is a small error at the system or driver level. The solution is actually not difficult, the focus is on checking several key links.

1. Check whether the Bluetooth service is running normally

Sometimes Bluetooth cannot be connected because the Bluetooth-related services in the system are disabled. You can do this:

• Press Win R to open the run window and enter services.msc to enter;
• Find "Bluetooth Support Service" in the list;
• Right-click and select "Restart";
• If the status is "Stopped", start it first and change the startup type to "Auto".

If this service is not running, the connection cannot be established even if the device is already paired.

2. Reinsert the Bluetooth adapter or update the driver

If you are using an external USB Bluetooth adapter, you can try to unplug it and plug it back, or try changing to a USB port. Sometimes the system fails to recognize the adapter, which will cause the connection to fail.

If it is a built-in Bluetooth module, it is recommended to go to the device manager to update the driver:

• Press Win X → Device Manager;
• Expand the Bluetooth option;
• Right-click your Bluetooth device → Update drivers;
• Or directly uninstall and restart the computer to allow the system to automatically reinstall the driver.

3. Delete the device and re-pair it

Sometimes old pairing information may go wrong, and the device record should be completely cleared and then re-paired:

• Open Settings → Devices → Bluetooth and other devices;
• Find the device that is in trouble and click it → “Delete Device”;
• Then click "Add Bluetooth or other device" to re-pair;
• After the pairing is complete, check if it can be connected.

This method is suitable for common Bluetooth devices such as headphones, speakers, and mice.

4. Confirm the power and connectable status of the equipment

Although it sounds a bit basic, many users ignore this. For example, if the Bluetooth headset is out of power, is in the charging compartment, or is not entering the connectable mode, it will cause it to be unable to connect.

• Check if the equipment is powered;
• Whether it has entered pairing/connection mode (some headphones require double-clicking the button to switch);
• If there is an indicator light, check whether it is flashing or is always on, which means waiting for the connection.

Basically these commonly used methods. When encountering "paired but not connected", most of them can be handled from the four aspects of service, driver, pairing information and device status.
