If bluetooth is on. Why Bluetooth can't find devices available for connection

Before proceeding with the study of the question itself, we will find out what Bluetooth is and how it works.

What is Bluetooth? This is a module for wireless data transmission. They can be voice, streaming (audio) and regular files. It works in two modes: both as a receiver and as a transmitter. This wireless device is indispensable for transferring files from your smartphone to your computer.

The Bluetooth adapter can be of different revisions or versions, starting with 1.0, which came out in 1998 and had a number of compatibility problems, and ending with version 4.1 with low power consumption and high speed.

V mobile computers, the wireless module reduces the battery life of the device. Therefore, manufacturers have provided both hardware and software to enable / disable these modules. Below is the instruction on how to enable bluetooth adapter on laptop.

How to find out if a laptop has bluetooth

You can try to turn devices on or off, puzzle over why it doesn't work. But it just might not be in the laptop.

There are several ways to check the availability of a function on a laptop.

by laptop part number;
by the corresponding stickers;
by the presence of the bluetooth status indicator.

The part number is the full name of the laptop model. For example, if we are talking about ASUS, it will look something like this: X102BA-DF010H. By entering this number in the search on the manufacturer's website, you can find out if the laptop has this function.

Be careful and carefully check if all letters and numbers match your model. A number with one slightest difference may correspond to a completely different laptop.

Sometimes laptop manufacturers indicate the availability of additional options with stickers. So, a sticker with the bluetooth model and version can be glued to the bottom of the case. If there is such a sticker on the bottom of your computer, then everything is in place.

If there is a small bluetooth logo on the dashboard of the laptop, this is a sure sign that it is present in this laptop... If it is not there, then you need to examine the keyboard for hot keys to enable this option. But the surest way is to check by the partner number, which never lies.

Bluetooth in BIOS

Sometimes after changing the hardware configuration, after reinstalling the OS or after other manipulations with the computer, the system does not see wireless devices: neither bluetooth nor Wi-Fi modules. It is a sure sign that these modules are disabled by software through the BIOS.

How to turn on bluetooth on a laptop in BIOS? You can do the following:

go to BIOS. To do this, you need to hold down the DEL or F2 key when starting the laptop. V latest versions laptops to go to BIOS, use the ESC or F1 keys;
check the status of the bluetooth module. Opposite the value "bluetooth" should be "enable". If "disable" is displayed, change the value. If it is impossible to turn it on or off in the BIOS, it means that it is constantly active. If at boot BIOS it is not visible - you need to flip through the pages and menus;
be sure to save the settings change and restart your computer. After that, the OS will detect a new device and request a driver.

How to turn on bluetooth in a laptop

First you need to install the drivers provided by the manufacturer. Even if after Windows installations standard drivers are embedded in the system - they may not work correctly with different models devices. You need to download drivers only from the official websites of laptop manufacturers.

The standard way is:

in the notification area, click on the oval Bluetooth icon;
in the menu that opens, click enable / disable Bluetooth.

Inclusion methods

Basic tools:

using hardware buttons;
using the keyboard;
through the OS control panel;
from the command line.

Some laptop models have hardware switches. If it is there, you need to move it to the "ON" position. These switches are often found in premium notebooks such as the Sony VAIO.

Keyboard shortcut

Almost all laptops are equipped with an FN key, which is always used to access additional opportunities laptop. Combined with others, this key can control the speaker volume, display backlight brightness, and auxiliary equipment on and off.

You can enable bluetooth in a laptop using the key combinations FN + the key with the bluetooth icon. This key is usually F3. Often bluetooth and Wi-Fi are one module. Accordingly, they are also turned on and off together with the FN + F5 key combination. Next, we will consider how you can enable this module without a keyboard.

How to enable without keyboard

If the keyboard does not work, the adapter can be turned on without it. Different versions OS include different ways software inclusion wireless devices... Consider the simplest and easiest ways for each operating system... Let's start with the freshest.

It's also very easy to do this in Windows 8.1.

In Windows 8, this is just as easy:

In Windows 7, the easiest way to monitor the operation of bluetooth is using factory utilities, which often come with a laptop, or are available for download from the computer manufacturer's website. The interface of such programs is extremely simple, and they do not need explanation.

It is also convenient to control the state of the bluetooth adapter using a special icon to the right of the taskbar. By clicking on this icon right click you can access the various modes and capabilities of the adapter. You can turn it on and off, pair with devices, control data transfers, and more.

If these methods do not help, make sure that the bluetooth module is enabled in the device manager. Also check if the drivers are installed correctly.

For this you need:

open the control panel;
in the category "Administration" go to the item "computer management". The computer control panel will open;
by going to the "Device Manager" tab, you will be able to see all the devices and modules running on the computer. Find your bluetooth device.

If there is a pictogram with a question mark or exclamation mark- drivers need to be updated or reinstalled.

It may happen that in nature there simply does not exist a driver for your bluetooth adapter for some old Windows versions... For example, for XP, many laptop manufacturers do not test or even write drivers. You can work around this problem by purchasing an external bluetooth adapter.

Using the command line

Controlling the status of wireless devices is also possible from the command line. But this method is much more complicated than all of the above.

For frequent use, this process can be simplified a little. The command: "devcon enable ID" can be placed in an empty text file, which will then be saved with the * .bat extension. To enable the adapter, it will be enough to run this file with the command.

If there is no fn button

It is extremely rare that laptops lack the FN button. It is not so convenient to operate the laptop without the fn button. But, you can turn on Bluetooth without it. You can use by software from different software vendors.

Some of them:

Lenovo ReadyComm - for Lenovo laptops;
ASUS Wireless Console - for ASUS laptops;
HP Utility Center is a comprehensive utility from HP for managing all devices, including Bluetooth;
Widcomm, AirShare is a paid and free third party utility.

These programs are extremely easy to use. For example, let's see how bluetooth is turned on via Widcomm software:

after installing the utility, a shortcut with the Bluetooth logo will appear to the right of the taskbar and on the desktop;
on click right key the mouse will open a menu with a ton of options. Among them there will be an item "Enable / disable Bluetooth-device";
by clicking on it with the left mouse button, wireless adapter will turn on.

Also in the absence function key, you can use the methods described above:

inclusion through command line;
inclusion through the control panel;
switching on using hardware switches.

Bluetooth can be turned on in several ways. If you are not well versed in the work of a computer, then use a method that you understand. You shouldn't use the command line and other complex schemes.

If you are using Windows 8, then there should be no problems with starting the bluetooth module. All hardware manufacturers regularly update their drivers for this OS. In addition, the interface and operation with Bluetooth is user-friendly and free from any problems.

To turn on the bluetooth module installed on your laptop, you need to either find the hardware power button or do it programmatically from the notification panel.

To enable it programmatically, you need to find the bluetooth icon in the notification panel and enable it through the context menu. The notification panel is at the bottom right, next to the clock.
You can use a separate Bluetooth button on the body.
To use the combination of buttons Fn + (F1 ÷ F12) is rare today. From the F1 ÷ F12 buttons, you need to select one with an antenna or the Bluetooth sign itself.

If a button is used to turn on, then there may be the following sequence of operation: "Wifi ⇒ wifi + bluetooth ⇒ bluetooth ⇒ everything is off".

That is, these switching modes are sequentially sorted out, and you can choose that in this moment must be enabled.

If you get a message that "bluetooth has been disabled by the user" then, in this case, you definitely need to use the button.

How to turn on bluetooth on a laptop, you can read in the instructions, because there are a lot of models and there are features that only this device can have.

More about software enable

On some laptops, the bluetooth module is put into operation through the operating system. To do this, check the tray of your laptop and turn it on there.

Press the right mouse button (RMB) after hovering over the bluetooth icon, there in the appeared context menu choose "enable".
If this icon was in the tray, and then somehow disappeared, then try updating the bluetooth driver from the laptop manufacturer's website.
Alternatively, you can be advised to restore the system until the moment when the bluetooth was still working normally.
You can also check on the official website of the laptop manufacturer, maybe they have special utility to enable wireless networks (Wi-Fi, Bluetooth) on your laptop.

How to enable bluetooth on Windows 8

For enable bluetooth in Windows 8 you need to find "parameters" in the lower right corner of the screen and click "change computer parameters". There you find " wireless connection", Then find" bluetooth "and turn on.

By clicking on this item, you activate the search by the laptop itself for devices with bluetooth, and the laptop itself will become available for searching by other devices.

Bluetooth on Windows 7

Turning on the seven can be done using the bluetooth icon in the notification area (bottom right, next to the clock). By right-clicking on the icon, you will see the module control menu. Do not forget that during these actions the "bluetooth" switch on the laptop case, if any, must be turned on.

But, if you do not find the "bluetooth" icon in the notification area, then we can advise you to follow this path: go to the "Control Panel" and open "devices and printers", there you will see "Bluetooth Adapter" (there may not be such an item, even if everything is fine with the device) and by pressing the right mouse button you will see the menu of this object. From the menu, you can customize the display of the notification area icon and other options. If there is no “Bluetooth Adapter” icon, then in the “Devices and Printers” window, click “add device”. If the drivers are installed correctly, then the device will be found, and if not, then we do as it is written further.

The second way to find the "bluetooth" icon if it is not in the notification area. In the same notification area, click on the "Network and Sharing Center" or you can find it in the control panel. On the left side there will be an item "change adapter parameters" click on it.

There you should see " network connection Bluetooth ", right-click on it and click" properties ". Going to properties, open "bluetooth" and there we already find the parameters. If you do not find the item "bluetooth network connection", then it means that the drivers are installed incorrectly or another reason for the malfunction.

Bluetooth on Mac laptops

On Apple laptops there is a Mac operating system, and in this system it is easy to turn on bluetooth. There is always a "bluetooth" icon on the screen and by clicking on this icon, click "turn on bluetooth".

If bluetooth does not turn on

First . Make sure your laptop has exactly bluetooth module ... Indeed, in almost the same laptop models, there can be a different composition of the hardware. Even if there is a special button on the case for turning on bluetooth, or you see an indicator of the operation of this module, still make sure that the module itself is on the laptop.

To do this, look at the device manager. Through the "start" press the "control panel" and go to the "device manager".

Bluetooth will be immediately in the list or in the "network adapters" item.

Second. When buying a laptop with a pre-installed Windows operating system, you may experience the problem of lack of drivers for Bluetooth, also this problem occurs when reinstalling the system. And although the bluetooth module itself is working properly, due to the lack of a driver, you will not be able to turn it on. When checking the equipment through the device manager, you will see that there is bluetooth among the devices, but it stands with an exclamation mark in a yellow triangle.

This means that there is no driver installed.

Third . Another rare driver issue is using systems 32 and 64 bit... The installed bluetooth module can only work with one of them, and if you reinstall the operating system with a different bit depth, your bluetooth module may refuse to work. The only solution to this problem is to reinstall the system.

Fourth. When installing drivers, look carefully at the messages that appear; the installer may ask you to press the "Bluetooth" button, which is on the case, during installation.

If the laptop manufacturer's website has a driver only for Windows 7, and you have set yourself 8, then you can install the driver in compatibility mode with the previous version.

Fifth. What would be exactly make sure that the bluetooth module is working properly try to activate bluetooth on your other device. For example, on the phone. Then on the laptop in the bluetooth window you will see the available enabled devices, namely your phone.

At connecting laptop via Bluetooth with smartphones you may need to install additional software from a smartphone manufacturer. With such programs, you can definitely organize the transfer of files between devices; without these programs, errors may occur when connecting devices via bluetooth.

Sixth. Yet one of the reasons for not working Bluetooth may be the failure of the hardware module itself... But this happens very rarely, the main reasons are not correct work all the same software. These are correctly installed drivers, conflicts with other equipment, etc.

If the bluetooth icon in the notification bar is gray then it is not included. Then, through the control panel, go to the "Network and Sharing Center", there on the left you click on "change adapter parameters". Find bluetooth in the list and click RMB. You should now see a menu and at the top it should say either "on" (which means it's off) or "off" (which means it's on). If it says turn it on, so you turn it on. Then click "Properties", go to the "Bluetooth" tab and go to "Bluetooth Settings" and there, in the Settings section, put a checkmark everywhere.

Good day, friends!

I think that none of you will deny that such convenient technologies as Bluetooth and WiFi make our life much easier (and shorten), making the interaction of devices at a distance soft and silky. However, today I discovered a terrible fact - it is better not to keep Bluetooth and WiFi dongles in adjacent USB ports.

I have a MiFi at home - Huawei E560. The most beautiful thing brings the Internet to an old village house, which does not, did not have and will not have a wired telephone, wired internet and anything else wired besides electricity. Previously, the home was provided with the Internet with the help of a veteran of the Russian mobile Internet connection of the country - the Option iCon 225 USB modem, which at the dawn of its appearance mobile internet was bought for a frantic 3 thousand rubles from Beeline and from which even Beeline itself is now denying himself with the words, they say, we did not have such a modem. Of course, the modem is branded, with a sticker and, it seems, locked. Now, having tasted all the delights of the NetGear JWNR2000v2 WiFi router, which has been working for a couple of months in a city apartment, to deliver Internet to a PC in the village, I purchased the same MiFi and a Trendnet TEW-649UB WiFi dongle for it. Cheap and cheerful.

The dongle settled in a free USB port and began its work, from which for the last couple of weeks I suffered from constant interruptions in communication, strange "heavy" visits to the router's Web interface and slow Internet. However, the connection to MiFi from the tablet and smartphone was excellent. And why? Because I put the WiFi dongle for PC in the USB connector next to the Bluetooth dongle.

I hope that this information help someone. Thanks.

Instructions

However, in order to fully enjoy all these convenient and pleasant features, you must first enable bluetooth on your laptop and configure it. First of all, make sure that bluetooth is actually present on your laptop. Most manufacturers have very similar models laptops, which have different possibilities in an identical case, and it is bluetooth that this may concern in the first place. The presence of a button enable bluetooth and even a brightly glowing indicator is not evidence of the presence of a bluetooth module in a laptop. The fact that this model is really equipped with bluetooth is evidenced by a sticker on the case with the corresponding marking confirming the licensing of bluetooth.

If bluetooth is present, then you just need to turn on bluetooth on the laptop. Often bluetooth is turned on by the same antenna icon button as wifi. In other cases, bluetooth can only be turned on programmatically, for example, by right-clicking on the bluetooth icon in the tray and selecting "Enable". Of course, for this required drivers must be installed correctly. If necessary, use the website of the laptop manufacturer or the driver disc that came with your computer.

We install the USB-module into the corresponding socket on the computer case. As a rule, correct installation is confirmed by a color signal on the keychain body, usually blue.

The matter does not end with the installation of drivers, but only begins. Now you need to actually configure bluetooth. To do this, you can use either the program supplied with the module, or try to do it yourself in the Panel Windows management... In any case, the process is quite simple: you need to specify the name of the computer and its type (by default - “ Personal Computer"). This data will be used to display the computer on other bluetooth devices, for example, on mobile phone when searching for available devices.

The setup is complete. Now the computer will be detected when searching for bluetooth devices from the phone, and you can transfer photos to it, download music found on the network to your phone, or use the phone as a GPRS modem.

To turn on Bluetooth on a laptop running in an operating room Windows system 10, find the button to enable this function, which is located in several places at once. Also, if you put your laptop into airplane mode, Bluetooth will be turned off automatically. In some laptop models, to turn on Bluetooth, you need to move the hardware Wireless switch to the On position (for example, this principle of turning on Bluetooth applies to the SonyVaio model). If this is not done, then you will not see the Bluetooth settings in the system, even if the installed drivers... It used to be a common use of turning on with the Fn + keys and the Bluetooth icon, but on the latest models, this method of turning on Bluetooth is rare.

There is a way turning on windows 8.1, which is only suitable for this version of the operating system. To do this, open the Charms bar (it is on the right) and click on the Settings button, and then on Change computer settings. Select "Computer and Devices", and in this menu - the sub-item Bluetooth. If you do not see this item, go to other methods. After selecting the specified sub-item, the Bluetooth module will automatically enter the state of searching for devices and the laptop itself will be available for searching.

You can turn on Bluetooth on Windows by opening the panel on the right, moving the mouse pointer to one of the corners and clicking the Settings button. There, select Change computer settings, and in it - item Wireless network... The wireless modules control module will open, where you can turn off or turn on Bluetooth.

Without bluetooth technology, imagine a modern mobile equipment is no longer possible. Simple, convenient and fast connection A wide variety of devices at a distance of up to several meters allows you to transfer video or music from one phone to another, connect a headset or a GPS module.

Naturally, the owner mobile device with bluetooth support, there is a desire to do without inconvenient wires when connecting it to a computer. Fortunately, setting up bluetooth on your computer is easy. Of course, a computer is rarely equipped with a built-in bluetooth-module, but a USB-module is easy to purchase and connect, and its price is very low. Outwardly, such a module resembles an ordinary USB flash drive.

We install the USB-module into the corresponding socket on the computer case. As a rule, correct installation is confirmed by a color signal on the keychain body, usually blue.

Windows will detect the device and try to install drivers for it. It is better to take the drivers from the disk that comes with the module. As a rule, it has an installation program in the form of a wizard that is familiar to the user, which will guide you through all the necessary steps, copy files and make changes to the registry.

The matter does not end with the installation of drivers, but only begins. Now you need to actually configure bluetooth. To do this, you can either use the program supplied with the module, or try to do it yourself in the Windows Control Panel. In any case, the process is quite simple: you need to specify the name of the computer and its type (by default - "personal computer"). This data will be used to map the computer to other bluetooth devices, such as a mobile phone, when searching for available devices.

Adjust your computer's visibility to other devices. You can make it visible or hide its presence in the bluetooth space. In addition, you can select the services that will be available via bluetooth. Adapters support all services, so everything can be left enabled.

The setup is complete. Now the computer will be discoverable when searching for bluetooth devices
