What to Know

• Enable Bluetooth on the device, then go to your computer’s Bluetooth settings and choose to set up a new device.
• If prompted for a PIN code, confirm the number on both devices. If you don’t know the PIN, try 0000 or 1234, or consult the manual.
• Use Bluetooth to share your phone’s internet connection, transfer files between devices, or play music through another device.

This article explains how to pair your laptop with a Bluetooth device. Steps may vary depending on the device.

How to Connect a Bluetooth Laptop to Other Devices

There are many kinds of Bluetooth devices and these steps are only relevant to some. Consult the user manual for the device or the manufacturer website for specific instructions. For example, the steps to pair a Bluetooth surround sound system to a laptop are not the same as pairing headphones, which isn’t the same as pairing a smartphone.

1. Activate the Bluetooth function on the mobile device to make it discoverable or visible. If the device has a screen, look for Bluetooth in the Settings menu. Other devices have a special button.

On the computer, access the Bluetooth settings and choose to make a new connection or set up a new device. For example, on Windows, either right-click the Bluetooth icon in the notification area or go to the Control Panel to find the Hardware and Sound >Devices and Printers page.

When the device appears in the list of Bluetooth and other devices, select it to connect (pair) it to the laptop.

If you don’t know the PIN, try 0000 or 1234. If those don’t work, search for the device manual online to find the Bluetooth code.

Most modern wireless devices include Bluetooth support, but if your laptop doesn’t, you might need to buy a Bluetooth adapter.

Tips

Follow these tips to get better performance from your Bluetooth connection:

• If setting up the connection from the PC doesn’t work, initiate it from the device, for example, hold down the Connect button or find the option in the software settings for the device.
• Some devices that don’t have many buttons or options might connect to any laptop that’s listening. For instance, you might be able to find the device through the laptop and click to connect, and the device will indicate it’s connected without requiring a passcode of any kind. This is true for most headphones.
• Turn off Bluetooth when you’re not using it, to prevent battery drain.

How to set up Bluetooth on a computer and laptop

For about thirty years Bluetooth has been improved from the first to the fifth version, which are burdened with backward compatibility, have different technical features, parameters and capabilities. In some devices, the Bluetooth module is integrated into the System on a Chip (SoC). Each manufacturer of a particular device implements a wireless connection in its own way, so in some cases it is not always easy to set up Bluetooth and get it to work correctly. Here we will not touch on cases when Bluetooth does not work (see separate material).

Where to look for Bluetooth settings on the device

Bluetooth settings are either among the main settings, or near WiFi and cellular networks, or somewhere else at the request of the manufacturer of a particular equipment. In most modern devices, the Bluetooth settings are located in approximately the same place. If you couldn’t get to the wireless settings in a couple of taps or clicks, you should use the search inside the system settings. Even a not very advanced user can easily turn on and configure Bluetooth on any device on their own.

How to determine the Bluetooth version on a device

Sometimes it is important to know what version of Bluetooth the device is equipped with. For example, in version 4.0, it became possible to simultaneously transmit sound to two devices, which must also support Dual Audio Bluetooth 4.0. If any of the three devices are equipped with Bluetooth 3.0 or earlier, the Dual Audio configuration will not work.

To determine the version of Bluetooth on a Windows computer, workstation, laptop, netbook, and tablet PC, go to the Advanced section of the Bluetooth menu in Device Manager. In the LMP line with a number, the Bluetooth version will be encrypted:

• Bluetooth 1.0 b is referred to as LMP 0.x,
• 1.1 — like LMP 1.x,
• 1.2 — like LMP 2.x,
• 2.0 + EDR — like LMP 3.x,
• 2.1 + EDR — like LMP 4.x,
• 3.0 + HS — like LMP 5.x,
• 4.0 — like LMP 6.x,
• 4.1 — like LMP 7.x,
• 4.2 — like LMP 8.x,
• and the fifth Bluetooth is designated as LMP 9.x.

To determine the Bluetooth version on Mac computers and laptops, look for the Bluetooth Core Spec in the System Report from Finder. To determine the Bluetooth version on a smartphone or tablet, the easiest way is to install a third-party diagnostic application, such as Aida64, CPU-Z or the like. The page https://www.bluetooth.today/en/android details Bluetooth on Android and iOS, as well as applications from the Apple App Store and Google Play for wireless operation from a smartphone and tablet. A special certificate, all data and the Bluetooth version number can be found in the technical documentation of the device.

What to do in the settings if Bluetooth is not connected

To understand more about the possibilities of Bluetooth technology, consider another interesting situation when it seems that the wireless function is broken: Bluetooth simply does not connect. What to do if the Bluetooth on the phone or computer is turned on, but it does not see all or some devices nearby. Bluetooth technology has several features that you should be aware of in order to deal with these kinds of problems.

• Firstly, some wireless gadgets ask the user for permission to be discovered. Naturally, these are not headsets, headphones, speakers, mice, keyboards, and other peripherals. Devices that are eligible to request permission to be discovered primarily include mobile phones, tablets, PDAs, desktops, netbooks, laptops, and other portable equipment. It is possible that this problematic device also has such a function.
• Secondly, the visibility restriction can set a timer in the wireless settings section that is responsible for the visibility time of the device.
• Thirdly, it is possible that Bluetooth is not connecting due to new signal obstructions, or the increased distance of devices from each other.
• In extreme cases, you can try to reboot, reconnect yourself, reinstall Bluetooth drivers and even flash the device. Some gadgets support the function of flashing or updating via Bluetooth, which is so simple that even an ordinary user can handle it. This will definitely help if the master sees the slave, but does not transmit data or control functions. As a rule, in such a situation, the problem lies in the software.

About ten problems when connecting devices via Bluetooth and solving basic problems if Bluetooth is not working — read separately. Mechanical damage and other malfunctions will be eliminated in a specialized service center.

What to do if the built-in Bluetooth adapter is not recognized by the system

Usually, the built-in Bluetooth adapter, like Wi-Fi, works normally, and there is no problem for many years. Many hassle-free built-in Bluetooth adapters use ExpressCard, PCMCIA, or PCI interfaces. Bluetooth adapters with a USB interface from well-known brands can also be included in this category. Windows 11, 10, 8.1 and even 7 finds drivers for such equipment on its own, it is also possible download Bluetooth on USB adapter for Windows 10 / 11, 8 / 8.1, 7, XP (64-bit and 32-bit).

If nothing has worked so far, try using “Device Manager” to see if Bluetooth is listed. Take note that your PC may support Bluetooth functionality and still not show up in the devices list. That scenario occurs when there is no Bluetooth driver set up for the external adaptor or internal component. However, internal Bluetooth devices generally get detected, whether installed or not.

1. Click on the Cortana search bar and type “Device Manager,” and select it from the list.
   
2. Look for Bluetooth entries in “Device Manager.” If you see them, then the PC supports Bluetooth, but it may not be working correctly. Bluetooth locations in “Device Manager” include Bluetooth, Network adapters, and Other devices. If the item and driver are not listed, move on to step 3.
   
3. As previously mentioned, your PC can still support Bluetooth and not show it in Device Manager. In that case, you need to install the appropriate driver.
   

If you find a Bluetooth device within Device Manager and you still can’t turn it on, the issue lies elsewhere.

Update the Bluetooth Driver

Whenever a feature on a Windows computer doesn’t work, you should always look for updates. Like most components, Bluetooth adapters need software to work, and Windows 10 updates have been known to break device drivers and functionality.

Drivers are updated either manually or automatically. The manual method might be a bit tedious, but it will do the job. Just find out which Bluetooth device your computer is using (from the Device Manager). Then, search the name of the device and download the drivers from the official website.

Alternatively, you can download a third-party program that automatically downloads any missing drivers to your computer. These services are often paid options. However, be careful if you choose third-party software. Some programs are more apt to install the wrong driver. Back up your system drivers (at the least) before using the software to update your system components.

After installing the drivers (one way or another), restart your computer and try turning the Bluetooth on again.

Re-Enabling the Bluetooth Software

Sometimes, system errors occur that cause components to stop working correctly. This situation often happens with Bluetooth components, and the best course of action is to give the devices a “wakeup call.”

1. Go to “Device Manager” and find your Bluetooth component.
2. Right-click it and select “Disable device.”
3. Now, right-click the entry again and select “Enable device.”
4. Restart your computer and try turning on Bluetooth again.

If enabling and disabling fails to solve your Bluetooth problem, try uninstalling the driver instead. Sometimes, a fresh installation is all the device needs. Don’t worry, as this won’t mess up the device or make it disappear from the list unless you choose to delete the driver.

Bluetooth Support Service

Now, we’re going to have to delve a bit deeper. If none of the above solutions worked, it’s time to use the “Run” feature.

1. Hold down the “Windows” key and press “R” to bring up the “Run” window.
   
2. Type “services.msc” without quotes in the command box, and then press “Enter” or click “OK.”
   
3. A new window will appear with a list of entries. Right-click on “Bluetooth Support Service” and select “Start.” If you can’t click the Start option, choose “Restart.”
   
4. Unless you want to repeat the process above every time you start your computer, there’s one more step to take. In the “Services” window, click “Bluetooth Support Service” again. Navigate to “Startup type“ found in the “General” tab and select “Automatic.” Click “Apply” and then “OK” if needed.
   

What Else Can Cause Bluetooth Failure?

Although one or more of the above methods generally solve Bluetooth problems in Windows 10, there’s a small chance that you’re still struggling to get Bluetooth to work. In this case, contacting the manufacturer or your retailer would be your best bet. If not, getting a USB Bluetooth adapter should help.

Sometimes, it’s as simple as forgetting to install or adequately reattach the Bluetooth board/device when performing a laptop or desktop teardown, whether for cleaning or repairs. That scenario would cause Bluetooth to disappear from the Device Manager and make it not work.

Turning On Bluetooth

Bluetooth is a simple feature on Windows computers. However, that’s usually not the case. There’s a whole lot that can go wrong with it, from hardware to software issues. Before doing anything else, check if your computer supports Bluetooth in the first place (many older ones don’t) and update the software. Most likely, at least one of the methods should work.
