If Android does not connect via Bluetooth to a computer or laptop, then the causes of the problem may be hidden both in the operation of the phone itself and in the module on the PC. Usually the failure can be resolved on your own, but in severe cases such as hardware damage you have to contact service center.
This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
Attention! You can ask your question to a specialist at the end of the article.
Why doesn't Android connect to my computer via bluetooth?
First you need to understand which device refuses to work. Perhaps the Bluetooth module is simply turned off on Android. To turn it on, just go to the settings and move the corresponding switch to the “ON” position.
Increase
Bluetooth must also be turned on on the computer. On Windows 7, the module is enabled in the “Devices and Printers” section, and on Windows 10 there is a separate tab in Settings. In addition, you must allow other devices to discover your computer, otherwise the radio signal will simply not be sent. Be sure to check if the necessary drivers for Bluetooth to work are installed on your computer. Without them, the module will not work and a wireless connection will not be established.
Increase If the module on the phone does not turn on or shows eternal loading, then the cause of this may be a system or hardware problem. Try rebooting your device, resetting your network settings, or performing a hard reset. Performing a hard reset will delete all user files from your phone, so be sure to back up your data first.
If problems with connecting via Bluetooth and transferring files appeared after installing custom firmware, you will have to abandon it. Use the official firmware from the smartphone/tablet manufacturer or look for stable builds in which all functions work correctly. If everything is fine on the software side, contact the service center. The Bluetooth module may have failed due to mechanical impact, water ingress, or other negative factors.
Correct connection of Android via Bluetooth to a computer
Most often, connection problems arise not due to system or hardware failures, but due to incorrect user actions. To avoid errors, follow the instructions for establishing a connection with a computer via Bluetooth.
- Open Windows 10 Settings and go to the Devices section.
- Go to the "Bluetooth" tab.
- Move the slider to the On position.
- In the Related Options box, click More Options.
- Check all the boxes on the Settings tab so that your computer can be detected on another device.
Increase On Windows 7, Bluetooth options can be opened by right-clicking the system tray icon. In the settings, you must also allow your computer to be discovered by other devices.
Increase The next step is to enable detection on Android:
- Go to settings, open the “Bluetooth” section.
- Turn on the module by moving the slider to the “ON” position.
- Below you will see the phone name. Click on it to change the mode to “Show for nearby devices.”
Increase After enabling the module and allowing display for other devices, the phone's name will appear in Windows settings. Click on it and then click “Pair” to establish the pairing. A secret code will appear on the screen of your phone and computer. You need to confirm that it matches, after which pairing will be established.

Bluetooth is a wireless connection.
The purpose of the device is to connect different devices, as well as file transfer and exchange.
The adapter functions as a regular radio receiver, which is configured to send a signal and to receive it. Simply enabling the function will not be enough to work.
For top level For security purposes, device detection is disabled. That is, in order for other opponents to see you, it must also be “activated”. Only after this the equipment is ready for use.

One of the main malfunctions in the operation of the adapter is that Bluetooth does not see the device. There are many reasons for this.
The most common:
- The software is not working properly.
- The device they are trying to find does not have discovery enabled.
- Big interference.
- The connected device is outside the adapter's range of influence.
Therefore, before you begin to fix the problem, you need to figure out why the device does not see the device.

Sooner or later everything requires adjustment. Bluetooth is no exception, which can also fail. What to do if Bluetooth on a laptop does not see the device? Let's solve this problem.
The adapter on a laptop may malfunction over time or immediately, during the first attempt to connect it. Find out the cause of the problems and begin to fix them.
We will look at options for changing configurations using utilities and how to configure the device in the BIOS.
Working with utilities on a laptop

Interestingly, utilities can switch the bluetooth state. So, for example, “airplane mode” can disable it altogether. For computers different brands These are different utilities, but there are many of them.
If, after reinstalling the Windows system, you do not want to install the utilities that the setup package provides, try downloading the necessary things from the official support page for your laptop.
There are options when you can replace the Bluetooth module configuration only with the help of utilities.
It happens that you can switch the adapter state only with their help (if you have original drivers).
BIOS settings
There are laptops in which you can configure Bluetooth functions in the BIOS system.
These include HP, Lenovo and others. As a standard, in the “Advanced” tab there is an item where you can turn the function off and on.
Sometimes - in the System Configuration tab, in the sub-items “Onboard Device Configuration”, “Wireless”, “Built-in Device Options”. The Enabled value in them should be “enabled”.
If there are no bookmarks with the word Bluetooth in the BIOS, you need to try setting the WLAN and Wireless items to the Enabled state.
Sometimes one tab is responsible for the active and inactive state of all wireless devices.
Bluetooth drivers: installation on a laptop
A fairly common cause of adapter malfunction is that the wrong drivers are installed or there are none at all.
How to recognize this problem in Device Manager:
- The yellow exclamation mark is next to the word Bluetooth.
- There is “unknown equipment” in the list.
- There are no similar sub-clauses at all.
- "Generic Bluetooth Adapter" is where "Bluetooth" should be.
Let's say you updated the device drivers and the system reports that the update is no longer required, but the module still does not work. This does not mean that the message is true. Windows simply doesn't have anything else to offer you.
To solve this problem, you need to install the driver and see if it helps. Download it from the website that represents your laptop model.
You can find the site by entering the phrase “Laptop_model support” into the search engine. If the driver you need is not available, use the most similar one.
In the case when something is already installed on your computer. You need to disconnect from the Internet and delete it.
Now you need to start installing the new software.
Often the representative's website offers not one, but several drivers for one version of the adapter.
To avoid making a mistake and select the correct one, you need to right-click on the word Bluetooth in the device manager.
Then, go down to the “Properties” / “Details” sub-item and find the “Equipment ID”. You will need the last line from the “Values” field.
Copy it and paste it into the search engine on devid.info. The system will sort the drivers that are most suitable.

If there are problems with the operation of the device on your phone. The very first thing to do is to determine the nature of the problem.
It is necessary to understand whether it is activated or not, does the problem occur when the device is turned on, or does it not work at all?
The adapter does not turn on
If the device as a whole does not activate in any way and shows constant loading, the cause of this incident is a hardware malfunction, a problem in the system, a virus on the phone, or a program installed with which there was a conflict.
To fix the problem, try rebooting your phone.
This action would be appropriate if the problem was lack of space due to an excess of temporary files or a system glitch.
When you perform this action, all your photos, songs and videos will be deleted. In order to save them, rewrite this data to another medium before resetting the settings.
In order to perform a complete reset of settings, you should follow the following algorithm of actions: “Settings” / “Reset settings”.
If even after performing this option the problem does not disappear, then the device is simply broken. The situation can only be resolved with the help of a service organization for equipment repair.
If it does not turn on in a newly purchased phone, replace it under warranty.
The mobile does not see the Bluetooth device, but the adapter turns on
If this situation occurs, you need to check whether Bluetooth is turned on.
Turning on Bluetooth
If yes, then you need to enable device visibility mode and disable the Discovery Timeout options. Now the device will work in correct mode.
The adapter turns on, but no data is transferred
If your mobile phone has an old version of the operating system, its VT module does not have a data transfer function.
To solve this problem, you need to update the OS - if you receive auto-updates on your phone. Or download the Bluetooth Fle Transfer application from the Play Market.
It is very convenient to use bluetooth to exchange information between your phone and personal computer or to listen to music using wireless headphones.
But there are unpleasant situations when, after Bluetooth updates, Windows 10 does not see the device. What to do in this case? Let's take a closer look at the situation.
Bluetooth device and driver status
First you need to determine whether your Bluetooth is still in place after the update? Are the drivers installed and how correctly do they work?
To check whether it is installed on your computer, go to the “Control Panel”, in the “Device Manager” section.
One of the sub-items there should be “Bluetooth”. If it is present, you need to check whether the drivers are installed for it? To do this, click on the name with the mouse and open the contents of the folder.
There must be an attachment in it. The main thing is that there is no exclamation mark opposite. This means that all settings are correct and everything is installed.
There are times when a failure occurs and the required module is turned off. In this case, a black arrow appears when the name is fiddled with.
To change the settings to “on”, you need to right-click on the name and activate the device.
If, however, the drivers are not installed, in the device manager, in the “other devices” sub-item, an “unknown device” will be placed, which, most likely, is your adapter.
To solve this problem, you need to update the drivers and specify the path to them.
There is another option when in the device manager you will not see anything related to Bluetooth and unknown devices.
You need to double-check and make sure that the adapter is even present on the PC. If not, you should purchase it from a specialized store and install it. The simplest adapter looks like this:
What does enabled Bluetooth look like on the toolbar?
If Bluetooth is fully working, present on your computer and even turned on, it should be displayed with a special icon on the toolbar.
Location: in the lower right corner, near the clock.
If it is missing, do not worry - it may simply be turned off. Auto-shutdown is most likely typical for laptops, since such programs consume an excessive amount of energy.
To activate it, you need to go to the menu on the toolbar and select the “Options” sub-item.
Then, go to the “Devices” section and select the “Bluetooth” sub-item.
If you use a laptop, you need to find a special key on the keyboard that turns the module on and off. If you don’t know where such a button is located, you may accidentally turn off Bluetooth all the time and puzzle over what’s happening with the adapter.
The phone does not detect the headset for listening to music
Bluetooth can also be used as wireless headphones. But why do problems arise when Bluetooth does not see other devices?
Pairing setup
Almost always, when you connect new equipment, pairing problems arise.
Sometimes electronics malfunction. Sometimes it's a hardware fault, sometimes it's a software problem. But most often it is a combination of a variety of factors.
If you connect the headphones to the charger and the indicator lights up, then everything is working normally and you just need to wait until the battery is fully charged.
If you connect the headphones to the charger and the indicator does not light up within a few minutes, the headphones may be faulty and you need to contact your nearest authorized electronics repair center.
Make sure the outlet you are plugging into Charger, working. If you connect headphones with a USB cable to a computer, make sure that the computer's USB port can operate in charging mode; not all USB ports can transmit the required level of current to start the charging process of the headphones. Typically, laptop USB ports that are capable of charging external devices are indicated by characteristic icons in the form of a lightning bolt, an image of a battery, or something similar. If nothing happens when you connect to one USB port, try connecting to another or to another computer.
The phone or computer does not see your wireless headphones because they are turned off
Wireless headphones have a so-called “standby mode”. It turns on when there is no active data transmission session to the headphones from the sound source. Those. you are not listening to music and the phone is not sending any sounds to the headphones. At this moment, the headphones are still connected to the phone or computer, but they are in “sleep mode”, power consumption is significantly reduced, but the battery is still consumed. And if you leave the headphones in this mode for several days, the battery will be completely discharged and they will stop working. Just charge the headphones and turn them on.
Pairing procedure
If you connect Bluetooth headphones to your phone or computer for the first time, you need to carry out the pairing procedure so that the phone and headphones transmit authentication codes to each other and start working in pairs. Without pairing your devices, your headphones won't work with your phone and your phone won't see your headphones in the list of available devices. You need to switch the headphones to pairing mode with the new device. Find out how to do this from the instructions below.
By following the link above you can get acquainted with detailed instructions initial pairing of devices. After this procedure, you will simply need to turn on the power to the headphones, after which they will automatically connect to the phone within a few seconds.
Wireless headphones do not connect to the phone because Bluetooth is disabled on the phone
This is a very banal reason, but you will be surprised how many people do not realize that they must turn on the Bluetooth module in their phone. Check, this is usually done in the Quick Access Toolbar or in the Settings menu. Just find the “Bluetooth” item there and check if it works. 
Some phone models have by default the option to hide the phone's Bluetooth from other Bluetooth devices, i.e. even if all devices are working properly and work as expected, they will not see the phone and will not be able to receive a signal from it. Try disabling this option. In the screenshot above I showed how it looks on my Xiaomi phone - it’s called “Visibility”. As you can see, in my case it is disabled, so all surrounding devices can see my phone and connect to it using Bluetooth. If I activate it, only previously paired devices will be able to connect to the phone, and new wireless headphones will not see the phone and will not be able to connect to it.
Wireless headphones do not work with the phone due to different hardware versions of the Bluetooth module
In general, this should not happen; Bluetooth is a backwards compatible technology, i.e. Bluetooth 3.0, Bluetooth 4.0 and should be compatible with each other. But this is in theory, but in practice it may happen that due to errors in the software or a combination of hardware and software failures, the headphones and phone may not see each other. This happens extremely rarely, but it does happen. Therefore, pay attention to what version of Bluetooth your phone and headphones have; if they are different, there may be a possibility of incompatibility between these two devices.
In this case, try connecting the headphones to another phone, preferably with a different version of Bluetooth. If the headphones work fine with another phone, then most likely you are faced with a rare problem of incompatibility between two specific gadgets. The only way to overcome the problem in this case is to replace the headphones or phone with a different model.
Once again, I want to draw your attention to the fact that this is a very rare problem and should only be considered if you have tried all other ways to connect wireless headphones and they did not work.
The distance from the sound source to the wireless headphones plays a key role for reliable signal reception
Make sure the sound source is within 10 meters of your wireless headphones. Please note that 10 meters is a reliable coverage area for Bluetooth devices without obstacles such as walls, cars and trees. If you want to install a sound source in one room and listen to music in another, be prepared for the possibility that serious interference may occur, including complete loss of signal. Bluetooth has a fairly low radio signal power and is therefore designed to operate over a very limited range. But electricity is consumed in very moderate quantities.
Headphones are broken
Wireless headphones are more expensive than their wired counterparts, so many people try to save money and buy inexpensive wireless models. Remember that there is no such thing as free cheese, and if you bought very cheap Bluetooth headphones, you may become a victim of the manufacturer’s total savings on every element of the headphones, from the hardware filling to software. The likelihood of breakdown increases significantly.
If your headphones do not work with your phone, make sure they are in working order. Try turning them on. If they don't turn on, put it on charge. If they don’t charge and don’t turn on, the verdict is obvious: they’re broken. If they charge but don't turn on, try putting them into pairing mode by holding the power button for a long time; depending on the model, you may need to hold the button for up to 10 seconds. If after this the headphones do not turn on and the phone does not see them, most likely they are broken and need to be repaired or replaced.
Another reason why wireless headphones fail is poor quality built-in battery. You bought headphones, listened to them for a couple of weeks, and then they began to hold a charge for only a few tens of minutes instead of the promised several hours. If this happens, this is a manufacturing defect and you should try to return the headphones to the manufacturer. Or, if there is such a desire, repair it under warranty.
Another type of hardware failure is constant interference during sound playback, even if the sound source is a few centimeters from the headphones. If, even at a very close distance from the source, the sound is reproduced with interference or is interrupted, this is a breakdown of the Bluetooth transmitting module. Depending on the situation, return the headphones to the manufacturer or have them repaired.
Water is the main enemy of wireless headphones. Unless the packaging or instructions clearly indicate that they are protected from moisture or splashes, try not to expose the headphones to water; even a walk in light rain can be fatal to the electronics. It is for this reason that I highly discourage the use of regular headphones during strenuous physical training. During training, you actively sweat, and sweat is much more aggressive ordinary water acts on electronic components. If even one drop gets inside the headphones, there may be serious problems up to complete breakdown of the device. You can only play sports with headphones that are protected from sweat and moisture.

One of the notable changes that appeared in Windows 10 is the work with Bluetooth. If in Windows 7 it was not entirely clear how to turn on the Bluetooth adapter and where to look for it, then in Windows 10 everything is much simpler and clearer. In this article we will look at how to enable Bluetooth in Windows 10, how to find the settings, and what to do if Bluetooth on the laptop does not work, there is no power button, and there is not even a Bluetooth adapter in the device manager.
If you don’t know if your laptop has Bluetooth at all, then you can look at the specifications on some website or in an online store. I think that if your laptop is not very old, then it has a Bluetooth adapter. It's just a driver issue. After all, if Windows 10 was unable to select and install the driver on the adapter itself, then Bluetooth, of course, will not work.
It may be that when you go into the settings, or try to turn on Bluetooth on your laptop, you will see that there is no power button or the “Bluetooth” section in the Windows 10 settings. We will also consider what to do in such a situation in this article. So that you don’t get confused, let’s do everything according to this scheme:
- Turn on Bluetooth on the laptop
- Let's look at the Bluetooth settings in Windows 10 (search for devices, connect devices, turn off the adapter).
- Let's figure out what to do if there is no Bluetooth power button. Installing and updating drivers.
Turn on Bluetooth in Windows 10
For some reason, everyone writes that to turn on the adapter you must use the key combination Fn+F2, Fn+F3, etc. Honestly, I don’t understand where this information comes from. On my Asus laptop, when I press the Fn+F2 keys (F2 with icon wireless network) Airplane mode is simply turned on and off. It is clear that for Bluetooth to work, the airplane mode must be disabled. If everything is different on your laptop, write about it in the comments.
Everything is much simpler. Click on the notification center icon and see a button there Bluetooth. Click on it and it will turn blue. This means that Bluetooth is already turned on. To turn it off, press this button again.
That's all :) You can connect devices, for example, .
If you don’t have a button like I have in the screenshot above, then most likely the adapter is disabled or the driver is not installed. Read about how to solve this problem at the end of this article.
Bluetooth device management, connection, configuration
To open the settings, view available and connected devices and enable detection of your laptop by other devices, just right-click on the Bluetooth button and select Go to settings.
A window with parameters will open. The laptop will search for Bluetooth devices and display them in a list. You can establish a connection with these devices. Just select the desired device and press the button To tie, and follow the instructions. If these are Bluetooth headphones, a speaker, etc., then they are already visible by default, and the laptop will detect them. And if this is, for example, a smartphone, then it may be hidden from search, and Windows 10 will not see it. This can all be disabled in the settings of the smartphone itself.
In the same window, there is also a button to turn Bluetooth on and off. As for the settings, there are not many of them. To open them, just click on the item Other Bluetooth options. A new window will appear in which you can only enable or disable detection of your laptop. If you uncheck the item Allow Bluetooth devices to find this computer, then all devices will not be able to see your laptop. But, you will see them and be able to connect to them.
Also, immediately after turning it on, an icon will appear on the notification panel. By clicking on which, you can quickly go to various settings: adding a new device, sending/receiving files, going to settings, etc.
These are the settings. You can easily connect and manage new devices. You are unlikely to transfer files, but wireless headphones, acoustics, mice, etc. are very convenient.
Bluetooth does not work in Windows 10. There is no power button
So, if there are no signs of Bluetooth on your laptop (there is no power button, and there is no section in the parameters), then most likely:
- The driver for the adapter is not installed.
- The adapter is disabled and therefore Bluetooth does not work.
- Or it is not installed on your laptop at all.
This is easy to check. We need to open Device Manager. To do this, right-click on the button "Start", and select from the list device Manager.
Next, find the tab Bluetooth and click on it. There must be one or more devices. If you have an icon near the adapter (in the form of an arrow), then right-click on it and select Engage.
After this everything will work.
What to do if the adapter is not at all in the device manager?
In this case, you just need to install the Bluetooth driver for the adapter that is installed in your laptop. This driver must be for Windows 10. In the manager, you will most likely have at least one unknown device, under the Other devices.
You can download the driver from the official website of your laptop, and it must be for your model. If you have a USB Bluetooth adapter, then look for drivers for it (model and manufacturer are indicated on the box). True, you may not find drivers for Windows 10. But I think this is rare, since the “ten” usually installs drivers for wireless modules itself. As a last resort, you can use a program to automatically search and install drivers. After installing the driver, you should see something like this in Device Manager (your names may be different):
If the stickers do not clearly indicate anything, and the packaging has not been preserved, look for information on the laptop manufacturer’s website or ask the support team a question.
Hardware enable adapter
To figure out how to turn on Bluetooth on your type of laptop, take a look at the keyboard and the front and sides of the case. On some models, a switch is used for this - you can recognize it by the Blue Tooth logo icon. On others, a combination of pressing Fn and one of the function keys (F1-F12). The symbols on the keyboard will help you determine where exactly to press.
On some laptops, such as the MSI X460 DX, there is a separate key to turn on Bluetooth:
On others, more often, it is combined with the Wi-Fi power button:
After activating the adapter, the “Blue tooth” indicator on the case will light up (if there is one, not all devices are equipped with it).
Despite the widespread use of more new technology WiFi and Bluetooth communication still remain relevant. Very often it is used for a wireless headset, as well as for quickly connecting a computer and a mobile phone. We told you how to do this. Of course, the data transfer speed via Bluetooth is significantly lower than via WiFi, but in some situations this is quite enough. Moreover, such a connection is much easier to implement. But, a common error occurs when Bluetooth does not find the device on a laptop with Windows 7. What to do in such cases?
Everything is extremely simple. It is important to know some rules, the observance of which will help you establish a connection easily and quickly.
Why Bluetooth doesn't find devices to connect to: Video
Preparing a Bluetooth adapter on a laptop
This one will tell you where to find and how to turn on Bluetooth on Windows 7.
First of all, if the Bluetooth wireless module does not work on a computer running Windows 7, you should check the drivers. Like any other device, the wireless module also needs software.
Therefore, if we are talking about a laptop, then insert the driver disk into the drive and install the necessary software. If there is no such disk, then you will need to log into the support site of your laptop manufacturer. On it you will find all the necessary drivers and additional utilities for working with Bluetooth.
If you are using an external USB Bluetooth adapter, then in order to download the necessary drivers you will have to enter the full name of the device in the search engine. After installing the drivers, we just need to enable the module. This is done by pressing the power key, which is usually combined with activating WiFi communication. It is worth noting that if in Windows 7 the Bluetooth icon disappears from the tray, this means that the module is disabled or the drivers are not installed.
How to reinstall drivers for Bluetooth: Video
Preparing the module in the connected device
Very often, problems with detecting devices on a computer with Windows 7 are related specifically to the connected device. The fact is that in most cases, to save battery and increase security, detection of, for example, a phone is turned off. In other words, the module works, but other devices such as laptops cannot detect it. If the module is not installed, read this. The solution is extremely simple. You need to go into the Bluetooth settings (if it’s a tablet or smartphone) and put it in the “Detection” line. Typically, it turns on for no more than 2 minutes. If you did not manage to connect during this time, you should enable discovery again.
If we are talking about devices such as printers, headsets, and so on, then they have a discovery button that must be pressed before starting to search for available devices on the computer. After this, the error when Windows 7 does not see Bluetooth devices will be resolved. We have already talked about the wireless headset in more detail.
How to search for devices on a Windows 7 computer
After you have completed all the above steps, the adapter needs to be configured. To do this, find the corresponding icon in the tray (lower right corner of the desktop). If you right-click on it, a menu will appear in which you can disable the adapter, show Bluetooth devices, and so on.
Among the options we are interested in is “Open Settings”. Let's choose it. After this, a menu will open in which you can configure our module. Here we need two tabs:
- Options.
- Sharing.
In the first, you need to check all the boxes except the line “Disable Bluetooth adapter”. This way we will enable PC discovery and also allow devices to connect to it. Moreover, when you try to connect, the system will display a message.
In the “Sharing” tab, you need to check the box to allow file transfer (music, video, photos, and so on). A little lower you can specify the folder in which all files transferred via Bluetooth will be saved. This completes the setup. To get more detailed information about the settings of the wireless adapter, go to the “Settings” tab and click on the inscription “Configure settings for Bluetooth devices”. This is a built-in function that describes in detail absolutely all aspects related to the settings of such equipment.
Now you can move on to searching for equipment available for connection. To do this, click on the Bluetooth icon in the tray again. This time select "Add device". A window will appear showing available connections. However, before returning the list, the computer will perform a search (everything happens automatically). At the same time, as mentioned above, if required, detection must be enabled on the connected equipment so that the laptop can detect it.
