How to turn on Bluetooth on a laptop: life hack for the latest 3 Windows OS
The Bluetooth wireless communication function is a useful option for a laptop when interacting with smartphones or related gadgets like headphones, mice, keyboards, speakers. It is always possible to quickly transfer small amounts of files without using other programs and applications. All laptops are equipped with a bluetooth module to expand capabilities.
However, this option is rarely used, taking it in Windows It is not a priority. Therefore, not everyone succeeds in finding and turning on bluetooth on a laptop the first time. Here the brand of the device does not depend on the settings, it is determined by the operating system.
How to deal with Bluetooth in the G8
On laptops, it is rare, but still there is a bluetooth connection activation key. Most often it is located next to Wi-Fi activation. And in Windows 8 there is a built-in control unit for different types of wireless communication.
“Eight” is considered comfortable for the user, however, a number of questions arise when using it. In the case when version 8 is on the laptop, then you can activate the bluetooth connection as follows:
1. You need to go to the right panel, move the cursor over its corner and go to the “Parameters” tab.
2. Next, you need to open “Change settings.”, And immediately go to the wireless network settings.
3. The panel of wireless communication modules will appear. It is there that you can activate or deactivate bluetooth.
After THESE manipulations with the settings, in order to connect the gadgets, it is necessary in the “Change settings” tab. Select “Device” and then enable search clicked “Add device”. If you need to provide a wireless connection with your smartphone, you should configure “Discovery” in the menu. Perhaps all of the above will NOT cause Bluetooth to work. Then you should look in the device manager to see if the module is activated there. In it, you can also see what the drivers are. To enter there, you need to hold down the combination of the Windows and R keys, and then enter devmgmt.Msc in the line.
Then the properties tab of the adapter opens, where you can look at the list of errors in operation. After that, you should look at the drivers themselves, who the supplier is, the year of release. If Microsoft driver is too old for laptop. A newer one should be sought.
It may happen that the G8 is already installed, and the manufacturer’s websites only have drivers for Windows 7. Then you can try to install them. Usually they can work smoothly with the previous OS.
You can turn on bluetooth on a laptop with Windows 8.1 in a slightly different way than on all laptops with other operating systems. This method is SIMple, but it is not the only one for activating the module.
- You need to go to the right panel and go to the “Parameters” tab, then open the “Change parameters” section.
- Then click “Computer and Devices”, in the paragraph there will be Bluetooth. In the event that there is such a comment, then you should refer to other methods.
When this item is selected, bluetooth goes to search for gadgets, at the same time the laptop becomes visible for searching and connecting.
For operating systems 8 and 8.1, it is recommended to install the program for wireless adapters. With its help, you can conveniently manage them.
Let’s find bluetooth in the “seven”
If a laptop with Windows 7, then bluetooth is activated using the factory utilities, or refer to the icon that is located on the notification bar. If you click on the icon with the right mouse button, then, taking the type of adapter and the type of drivers, the control menu will be displayed. It should be remembered about the Wireless switch, which must be turned on, but it is not always there on the laptop.
When you see that there are no icons on the panel in notifications, but the user is sure that the drivers are in order and bluetooth is available, then you need to act differently. The first option would be like this:
1. Open the management tab, click “Devices and Printers”.
2. Right-click on the Bluetooth Adapter (the position may have a different name).
3. In the event that this item is available, then you must select “Bluetooth settings”. Here you can configure the display of the icon on the panel, the visibility mode for devices and other characteristics.
4. If the item is missing, then it is possible to connect via bluetooth by SIMply clicking “Add device”. The laptop will automatically detect the gadget.
In case of failure, there is a second option:
- Right-click on the icon that displays the Internet connection on the laptop panel, then select “Control Center.”.
- In the menu on the left panel, click on “Changing parameters.”.
- And now again right-click on “bluetooth network connection”, and then click “Properties”. If such a tab is not observed. It is likely that the laptop has driver problems.
- In the properties panel, select “Bluetooth”, and then go to the parameters. From there it will be possible to configure the option to work with it.
Now everyone knows how to enable bluetooth on a laptop in Windows 7. Before looking for settings, you should make sure you have an adapter on your device. This operating system has been used on a laptop for a long time. On older models, Bluetooth may not be available. You should also remember that without drivers, nothing will work. They come either immediately with a new laptop, or downloaded from the official website.
Innovations in the bluetooth menu from “dozens”
Setting up Bluetooth on a Windows 10 laptop is very easy. The developers, taking into account the shortcomings in the details of the past operating systems, changed the interface to a more convenient one. Activation buttons are now located on several different panels. You should also remember that in the “Flight” mode, bluetooth is automatically turned off.
To enable, click on the “Notification Center” icon, it looks like a letter. The translucent panel will unfold, and you can see the bluetooth inscription, you need to click on it. The button will light up blue, it means Bluetooth wireless mode is working. To turn off, press the same button.
But that’s not all. In any case, you have to set up connections, watch available devices, etc. To do this, right-click on the bluetooth button on the panel, and then click on “Go to.”. The parameters tab will open, where in the form of a list you can see the found devices. It’s easy to get in touch with them, just click on the name, and then “Link”.
In the same panel there is another bluetooth activation button. It’s easy to figure out the settings themselves, since there are not many of them. Clicking ” options” will bring up additional settings, including whether the laptop is discoverable by other devices.
You can use the icon on the panel as soon as bluetooth is turned on. I called it, a list of settings will be displayed.
The situation with how to turn on bluetooth on a laptop has cleared up. We must NOT forget the main thing: the Bluetooth module will function correctly with the native drivers installed, downloaded from the website of the laptop brand. Users constantly face the problem of reinstalling Windows. After this process, they Try to use either the drivers from the old version, or the one that the system has loaded. This is not recommended. It is this non-observance of the rules, as well as the incompatibility of technology, that is a prerequisite for Incorrect operation of the module, or the inability to start.

Possible difficulties and ways to solve them
What to do if the laptop does not find the device for bluetooth connection? Most likely, a tablet, smartphone, or some other gadget has invisibility enabled for unpaired objects. Or discoverability is disabled on the laptop in the Bluetooth settings. It is necessary to name the module as an auxiliary mouse button, go to the “Settings” tab and check the box next to “Allow devices by detecting this computer”.
If you still cannot connect, then the device is probably out of range of the radio module. You need to place it as close to the laptop as possible. Although it is believed that the range for data transmission via bluetooth is 10-50 m, in fact this value is much lower. Indeed, in living quarters and offices there are various devices (cordless phones, microwave ovens, etc.) that interfere and interfere with detection.
The preparatory stage for setting up Bluetooth in Windows 10 means checking for the presence of the module itself. It is without him that it will be impossible to launch Bluetooth in Windows 10.
Determining the presence of an adapter on a laptop is quite SIMple. Its icon is located on the keyboard, or rather is located on the F2, F3 or F9 keys (depending on the device model).
If there is such an icon, it is worth studying the technical specifications of the PC. If you don’t have instructions, there is a sticker on the back of the laptop or on the front panel. It always has a Bluetooth icon (if available for this model).

Mobile devices are strong in communication technology. One of these technologies, designed to unite everything around, is called Bluetooth.
At the end of 2005, there were about 500 million Bluetooth-enabled devices in the world. Their number is constantly growing. According to some forecasts, in the very near future, most of the produced mobile phones will be equipped with Bluetooth-modules. All this is NOT accidental. BT technology is very convenient. I think everyone who has come across this type of Near Radio communication will confirm this.
History and scope
Bluetooth (literally translated into Russian, the name of the technology sounds like “blue tooth”) was born in 1998 by the efforts of Ericsson, IBM, Intel, Motorola, Nokia and Toshiba (later the Bluetooth Special Interest Group. a group of developers of the Bluetooth standard. SIG).
The nickname of the medieval Danish king Harold (Harald Bluetooth Gormson) was chosen as the name of the technology. This king is known as the unifier of the formerly warring lands. And the Bluetooth technology of inventions (this happened in Sweden) for combining various devices. mostly mobile. Bluetooth logo creators were inspired by nordic runes.
After the founding of SIG, many more companies (about 4000) joined this group. and today the described technology is capturing the market at an incredible speed. This is easy to see if you look at modern mobile devices. Almost any mobile phone, starting from the middle level, is equipped with Bluetooth support. The same can be said about PDAs and notebooks. So why do we need this innovative technology? Let’s look at the options for using it.
Why Bluetooth is needed?
Several devices connected by Bluetooth are called a piconet. Any devices equipped with Bluetooth can find a “common language”. That is, to connect to exchange data. over, a variety of interaction options are possible.
For example, you can link a pair of cell phones in order to transfer pictures or melodies from one device to another, or connect a BT headset to your mobile phone. You can connect your cell phone to a PDA, laptop or desktop computer. for transferring various media materials (photos from your cell phone, pictures, melodies, recordings from your computer) and for accessing the Internet, for example, via GPRS. You can combine several computers (no matter what) equipped with a BT adapter into a small local network, as well as connect wireless printers to this network (there are printers equipped with BT adapters) and other shared devices. You can connect various bluetooth devices to your computer. mice, keyboards, headphones, GPS receivers. game consoles with support for the “blue tooth” have been created, as well as a lot of bluetooth adapters, which can be connected to almost any computer. from to desktop. And that’s not all.
Now let’s take a look at the Bluetooth specifications.
As we said, Bluetooth is a Near-Field Communication technology. BT networks operate in the 2.4 to 2.485 GHz range, using the frequency hopping capability (1600 hops per second). This is done in order to ensure that other devices work in this range. The fact is that the specified range is unlicensed in many countries. wireless networks of the Wi-Fi standard, cordless telephones operate in it, and “noises” from microwave ovens, medical and scientific equipment also go here. As a result, the developers had to work hard to make the normal functioning of BT devices possible.
Initially, Bluetooth provided a maximum data transfer rate of about 720 Kbps, which is sufficient for most applications of this technology. The maximum communication distance was limited to 10 meters. Considering that Bluetooth is a radio communication technology and opaque objects are NOT a hindrance for it, 10 meters is quite enough. The new Bluetooth specifications are already talking about a range of 100 meters and a speed of about 3 Mbps.
Bluetooth chips consume very little power. this is what makes them successfully used in many mobile devices. BT has competitors in this area. In particular, IrDA infrared communication technology and Wi-Fi wireless local radio network technology. Bluetooth successfully competes with IrDA. using BT is much more convenient. But with Wi-Fi everything is not so SIMple, BT and Wi-Fi rather DO NOT compete, but complement each other. In particular, Wi-Fi is more reasonable and convenient to use where fast (tens of Mbit / s) and sufficiently long (tens of meters) communication between computers is needed, and the destiny of Bluetooth is communication “everything with everything” without special requests for speed and range communication. BT allows you to create local networks, but they are good only for exchanging small amounts of information. transferring even a couple of hundred megabytes will take an unforgivable time.
The widespread adoption of Bluetooth has spawned some special mobile entertainment with its introduction, and has also made the public debate the security of the technology.
Bluetooth was created as a technology that automates the relationship between devices as much as possible. The advantages of this approach are obvious. the user spends little time and effort connecting devices. The main disadvantage is that the risk of unauthorized connections and actions increases significantly.
The problem with Bluetooth is that the standard is relatively new, and it often happens that new standards have some flaws, flaws, which are corrected later.
Bluetooth devices are subject to a certain danger. there are attacks on such devices aimed at various purposes. from stealing information and browsing the Internet at the expense of a user whose device has been successfully attacked to sending harmless messages (BlueJacking). There are viruses (mainly mobile viruses) that spread via Bluetooth.
All Bluetooth devices are attacked. The main recommendation that can be applied to prevent such attacks is not to turn on Bluetooth device discovery unnecessarily. However, even following this advice will NOT eliminate your risk.
If we talk about human safety, then the use of BT-headsets allows you to minimize the impact of cell phone radiation on health.
There are such concepts as Bluejacking (or saucer in Russian) and BlueChalking (bluechaking). The site www.Bluejack.Ru gives the following definitions of THESE concepts: “BlueChalking. This is a way to meet and communicate with people, use network services using devices equipped with a wireless Bluetooth interface. Bluejacking. Much the same as BlueChalking, except that bluejackers usually send anonymous messages for fun. Their interest. Observe the reaction of people who receive their messages “.
If you are interested in saucing, or SIMply communicating via Bluetooth, you can use specially developed software for THESE purposes. In particular, there are programs for PCs, PDAs and cell phones that allow you to use Bluetooth connections for communication. Owners of cell phones can find software for Bluetooth communication on the website http://mobiluck.com/, and those who want to communicate using a PDA or PC. on http://www.Buzzone.Net/rus.
Now let’s say a few words about the features of practical use of Bluetooth, the knowledge of which will allow you to establish a connection with almost any BT-devices.
In order to establish a connection between two Bluetooth devices, you need to follow these steps:
1. Turn on Bluetooth adapters on both devices and bring them to the interaction distance (usually about 10 meters).
2. Initiate a search for other BT devices on one of the devices. During the search, you will be presented with a list of found equipment, in which you must find the device with which you want to connect.
3. Start the connection procedure (for example, select a device and click the “connect” button or select the “connection” menu item).
4. Enter the same Bluetooth identification key on both devices. As a rule, first it is entered on one of the devices, and then the second device asks for a key. you need to enter exactly the same key on it. If you are Connecting, for example, a BT headset and a phone. see the key in the documentation for the headset.
5. After the preliminary procedures are completed, you can engage in data transmission via Bluetooth, use the services provided by the paired devices.
If you work with a computer BT adapter. Please note that usually the software supplied with such an adapter allows you to automate almost any kind of connection.
Equipment setup. How to turn on Bluetooth on a laptop and configure it
Every modern laptop, netbook or ultrabook is equipped with a radio module with Wi-Fi and Bluetooth. This trend is followed by almost all laptop manufacturers. HP, Asus, Acer, Toshiba, Samsung, Lenovo, etc. And the most interesting thing is that fewer questions arise with the wireless network. it is, as a rule, initially turned on, the user connects to the home network and then works quietly. But questions about Bluetooth arise. No wonder. there is a separate button. This is to mislead a novice user, and he quite logically has a question. how to turn on bluetooth on your laptop ?! And the casket just opened. But first things first.
I will take an HP (Hewlett Packard) Pavilion laptop as an example.
Since the Wi-Fi and Bluetooth radio module on the laptop is one single, it turns on with the same button with the antenna image. On older models, a separate button on the body of the device was used for this. On modern ones, as a rule, the Wi-Fi and Bluetooth power button is combined with one of the function keys. In my case, this is F12. That is, to turn on Bluetooth on your laptop, you need to activate the radio module by pressing the button with the antenna:
However, keep in mind that very often this button should be pressed together with the “Fn” function key.
Very often this button is equipped with an additional Separate Status Indicator. If Wi-Fi and Bluetooth are off, it is red. After pressing the button, the adapter will turn on and the color will change to blue or white. After pressing the button, the following icon will appear in the Windows system tray:
This means that everything is included and you can connect phones and tablets. To do this, click on the icon with the right mouse button and select the “Add device” item:
The operating system of the laptop runs a scan and searches for available devices to connect. It goes without saying that they must be visible via Bluetooth. If everything is fine, then you will see your phone or tablet:
And all that remains is to connect to it and you can transfer files, music and.

What to do if Bluetooth doesn’t work?!
The most common reason is that the Bluetooth adapter is SIMply not turned on. over, as a rule, the user SIMply forgets to press the power button of the wireless module.
It also happens that the button itself worked, but the adapter did NOT turn on, so try again to turn it off and turn it on.
Note: Separately, I note that very often after reinstalling Windows 7 or Windows 8, users SIMply forget to put the driver on the functional buttons of their laptop and they, accordingly, do not work.
The second point. pay attention to the Bluetooth icon in the system tray next to the clock. If it is red like in the screenshot:
This means that the adapter was disabled programmatically. In this case, you need to name the icon with the right mouse button and select one single item in the menu that opens. Enable.
If these actions DO NOT help, then the problem is already at the driver and hardware level.
Then, first of all, go to the Network and Sharing Center and in the menu select the item “Change adapter settings”.
The network connections window will open. there should be 3 connections. wired network card, Wi-Fi connection and Bluetooth adapter:
Make sure they are active, i.e. The connection icon must NOT be grayed out.
If suddenly there is a Bluetooth adapter in the laptop’s network connection, then you need to look for it in the device manager. You can get into it in several ways. The fastest is to press the WinR key combination and write the devmgmt.Msc command in the window that opens:
The second option. you can right-click on the Computer icon in the Start menu and select the “Management” item. The “Computer Management” snap-in will open, in which you need to select “Device Manager”:
We are interested in the “Network adapters” section. If all the drivers are installed, then this list should also contain at least 3 items. wired network, wireless and bluetooth. As you can see, in my example, two devices. Bluetooth device and Bluetooth Personal Area Network. There are crosses and exclamation marks indicating problems with the equipment. this is already a good sign. It remains only to check whether the bluetooth network is running. To do this, right-click on the devices on the Bluetooth Personal Area Network:
If the context menu has an item “activate”. feel free to click on it. This was most likely the prerequisite for the malfunction.
