By default, Bluetooth is turned off in Windows 10. But with all the technologies available to connect with Bluetooth, it stands to reason that you would want to know how to turn it on and off at some point.
To save the battery usage of a laptop or other mobile device, Bluetooth should be turned off. Especially if it’s not connected to a device that you are currently using.
It’s not only beneficial from a battery savings perspective, but also for security and privacy reasons.
How to turn Bluetooth off
- Go to the Settings app by clicking the Start Menu. Click on the gear-shaped icon and the Settings app will open. Settings can also be opened by typing the word ‘settings’ in the search box and clicking on it afterward.
- After opening the Settings app, click on “Devices”.
- Then click on “Bluetooth & other devices” which is displayed in the left pane.
- At the top of the window, you will see a Bluetooth switch. Click on it to toggle it off. It will slide to the left (and it will turn white from blue).
After turning Bluetooth off, no other device will be able to connect to your machine via Bluetooth.
How to turn on Bluetooth in Windows 10
The procedure for turning Bluetooth on is virtually the same, apart from the last step:
- Go to the Start Settings by clicking the Start Menu. Above the power button, there will be a gear-shaped icon. Click the icon and the Settings app will open. The Settings app can also be opened by typing the word ‘settings’ in the search box and then clicking on it.
- After opening the Settings app, click on “Devices”.
- Then click on “Bluetooth & other devices” which is listed in the left pane.
- Now at the top of the window, you will see a Bluetooth toggle switch. You can turn it on by clicking on it. It will slide to the right (and it will turn blue).
When Bluetooth is turned on, you will be able to see a list of devices that are available in the immediate area. Select the one you wish to connect to.
How to send files via Bluetooth in Windows 10
Once the two devices are paired, you will be able to send and receive data between them.
- Select a file you wish to share and right-click on it. An option named ‘send to’ will be listed in the contextual menu. Hover your mouse pointer over it and you will see an option called ‘Bluetooth’.
- Left-click on ‘Bluetooth’ and send the file to the device you want.
How Bluetooth is integrated and connected
One of the ways Bluetooth can be integrated into a computer is through hardware that is embedded in the motherboard or your device.
Another way is through a connector like a PCIe mini card and is used internally as a separate component.
Bluetooth transceivers are also connected using external ports like a USB port for example. Again, if it’s kept on for a long time, it affects battery life.
Newer versions like Bluetooth 4.0 and other low energy Bluetooth (BLE) consume less power than before. But keeping it turned off when you aren’t using it, will save you significant battery power.
However, it’s a completely different issue if the device is being charged while Bluetooth is turned on. The worst outcome you may experience is a slightly longer charge time. It will be more likely that you won’t even notice a difference.
If you have a device that contains a Bluetooth module, you can easily connect with other devices supporting Bluetooth connectivity.
Bluetooth allows you to wirelessly connect one device to another, provided they both have Bluetooth enabled.
This allows you to send and receive files between the two devices. This is achieved by simply pairing them together.
The devices could be phones, tablets, headphones, microphones, keyboards, laptops, or other types of computers.
Windows provides various features and shortcuts to easily send and receive files from other wireless devices using Bluetooth.
The common types of files that usually get shared over Bluetooth are things like photos, documents, and music.
After you are done with file sharing, bear in mind that the enabled Bluetooth would still be using both the device’s battery life. This is the perfect time to consider turning Bluetooth off on them.
Importance of Bluetooth Technology
Bluetooth is a short-range wireless technology that enables two or more devices to connect to each other. These devices include mobile phones, laptops, desktops, tablets, and earphones.
The advantage of this technology is that it eliminates the need for connecting a large number of wires among the devices for data transmission.
It can connect two devices that are under a distance of 32 Feet (10 meters). More advanced and newer versions can provide a longer range, but the standard maximum distance is about 32 feet (10 m).
History of Bluetooth technology
So let’s see where the name ‘Bluetooth’ emerged. It is borrowed from the name of Denmark’s king named Harald Bluetooth a thousand years ago.
In the beginning, Bluetooth technology was designed to connect small personal devices (or peripherals) which include PDAs, cell phones, and headphones together.
They were able to cover a short area of around 30 feet, which is around 10 meters. Standard Bluetooth devices can communicate with each other at a data rate of fewer than 1 Mbps.
The technology was given a name as per its wireless specification that also replaces the frustration of wire connection. The radio frequency used by the Bluetooth technology is about 2.4 GHz.
At this frequency, devices employing Bluetooth technology perform the process of data transmission. Just by using the Bluetooth chips and embedding them into the devices, signal transmission using wires can be eliminated.
For the manufacturers that produced products like entertainment centers, digital cameras, PDAs, and MP3 players Bluetooth continued to be incorporated. These manufacturers felt uncomfortable with the continued use of wires, for the obvious need to remain competitive.
They continuously analyzed the need for some technology that does not involve any wires and that could perform the process of data transmission wirelessly.
As time passed and newer technologies arrived on the landscape of the technological world, the need started to revolutionize everything.
Bluetooth technology not only provided the facility of eliminating wire hassle for communication, but it also gave devices the ability to recognize each other and enable a quick connection for communication and data transfer.
In short, devices scan nearby signals and present a list of other Bluetooth-enabled devices as candidates to communicate with.
The pair is created as per a mutual agreement on data transmission and then the process of communication can follow.
Bluetooth technology employs the Personal Area Network (PAN). The Bluetooth specification of the phone can be seen in the settings of the device. Windows natively include this feature.
You can make use of another interesting Bluetooth feature that can be used between your PC, and another device such as your smartphone.
It’s called ‘Dynamic Lock‘. This feature can also be enabled or disabled independently.
Dynamic Lock allows your computer to be locked when the phone exceeds the maximum range of your Bluetooth connection. Obviously, this range will be determined by the capabilities of your hardware.
How to check if your device contains Bluetooth?
To check if the device supports Bluetooth technology, go to the ‘Device Manager’ that can be found by clicking on the Start Menu and typing ‘device manager’. Click on it when it appears.
There, look for Bluetooth in the Device Manager. It may appear on top. If not, you need to look under ‘network adapters’. In its drop-down menu, the Bluetooth hardware items can be found.
Sometimes, it is hard to find Bluetooth on the computer. The reason may be that the Bluetooth driver has not been installed or updated.
In this case, you need to manually update it by visiting the manufacturer’s website and updating it. Make sure that the version corresponds accordingly with the hardware.
The second step is to re-enable Bluetooth. Follow the steps shown earlier in this article to turn Bluetooth back on.
Once it’s been re-enabled, you will see a list of all the devices. Select one and enable the device.
What happens when you still cannot turn Bluetooth on?
If you still do not have any success, the second solution is to start the Bluetooth support service. Use the run command by pressing the shortcut keys as follows: Hold down the Windows key and tap R (Windows + R).
A command window should be open. Type in ‘services.msc’ and left-click on the ‘OK’ button.
The Services window should be open. Scroll and look for the Bluetooth Support Service, right-click on it and start it. A pop-up will appear to confirm the action.
Confirm by left-clicking on yes. Now, click on properties and then click on startup in the drop-down menu. Change it to automatic.
After restarting the computer, open the Settings app and follow the steps to turn the Bluetooth on as discussed earlier in the article.
If you still have no luck, consider looking at something to do with your Bluetooth component’s driver or the hardware component itself.
