Bluetooth wireless technology has long occupied its niche and has been popular all over the world for many years. At the same time, every modern smartphone, tablet, laptop, and so on, is equipped with such a module, with the configuration of which the heading “Bluetooth Settings” will help you. But, a very common error occurs when Bluetooth does not find a device to connect.
What is this error and why does it appear? In order to answer this question, you must first understand how the technology works and how to correctly search for available connections. It is worth noting that such errors are usually found on laptops, since operating systems have a very flexible configuration of radio modules, which is why users often simply make certain mistakes.
How the technology works
In fact, this is the most common radio communication that operates at a frequency of 2.4 GHz. Each adapter works both for receiving and emitting a radio signal. However, to improve security, device discovery is disabled. In other words, even if you have turned on the Bluetooth adapter, for example, on a smartphone, the computer will not be able to find it. See how to find and enable Bluetooth on Android devices.
After turning on the adapter, you still need to activate "Discovery" of the device. Only in this case you will be able to find the right equipment and connect to it. This is done to save electricity. After all, when the adapter is on and the discovery function is active, the Bluetooth radio consumes more power.
In addition, if we are talking about a computer, then the reason why Bluetooth does not find the device is that the drivers do not work properly. How to connect Bluetooth on a computer, we painted in a previous article. The fact is that for the correct operation of the radio module, special software is required. It is the appropriate software that allows you to manage the operation of such equipment. Usually, the drivers are available on the disk that came with the laptop upon purchase. However, if there is no such disk, then the necessary programs can be downloaded from the official website of the laptop manufacturer.
Why Bluetooth can't find devices: Video
Why is Bluetooth not finding devices?
There are a lot of reasons why Bluetooth does not find devices. The most common mistakes include the following:
- Disabled discovery on the target device.
- The connected device is out of range of the adapter.
- The software does not work correctly.
- Strong interference.
First of all, when connecting any equipment via a Bluetooth wireless network, you should check if detection is enabled.
As mentioned above, even with Bluetooth turned on, you can only find it by turning on discovery. If this does not help and Bluetooth equipment is still not found, then it is quite possible that the device is outside the range of the radio module.
The fact is that the adapter has certain limitations. Of course, the line-of-sight range can range from 10 to 50 meters, depending on the model. But it is worth remembering that under normal conditions, in apartments and houses, these figures are significantly lower. In addition, do not forget about the interference that household appliances can create, such as cordless phones, microwave ovens, and so on.
Often problems with finding available Bluetooth connections are caused by incorrect drivers. In this case, it is recommended to visit the official website of the laptop manufacturer and download the latest software version. If the software is installed correctly and everything works, then your radio module will be displayed in the Windows Device Manager. Moreover, you will be able to see its exact name.

Bluetooth (Bluetooth) is a wireless connection.
The task of the device is to connect different devices, as well as transfer and exchange files.
The adapter functions like a normal radio receiver that is configured to send and receive a signal. Just enabling the feature will not be enough to work.
For the highest level of security, device discovery is disabled in it. That is, in order for other opponents to see you, it must also be “activated”. Only after that the equipment is ready for operation.

One of the main malfunctions in the adapter is that the bluetooth does not see the device. There are many reasons for this.
The most common:
- The software does not work properly.
- The device they are trying to find does not have discovery enabled.
- Big interference.
- The device to be attached is outside the range of the adapter.
Therefore, before proceeding to fix the problem, you need to figure out why the device does not see the device.

Sooner or later, everything needs adjustment. Bluetooth is no exception, which can also fail. What to do if the bluetooth on the laptop does not see the device? Let's solve this problem.
The adapter on a laptop may fail over time or immediately, on the first attempt to connect it. Find out the cause of the problems and start fixing them.
We will consider options for changing configurations using utilities and how to configure the device in BIOS.
Work utilities in a laptop
Read also: How to distribute Wi-Fi from a laptop? The easiest ways
Interestingly, utilities can switch the bluetooth state. So, for example, "airplane mode" can turn it off altogether. For computers of 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 configuration package provides, try downloading the necessary information from the official support page for your laptop.
There are options when only with the help of utilities you can change the configuration of the Bluetooth module.
It happens that switching the adapter state is obtained only with their help (if there are original drivers).
BIOS settings
There are laptops in which you can configure the bluetooth functions in the BIOS system.
These include HP, Lenovo and others. As 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 must be “enabled”.
If there are no tabs with the word Bluetooth in the BIOS, you should try to set 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 an adapter malfunction is that the wrong drivers are installed or there are none at all.
How to recognize this issue in Device Manager:
- The yellow exclamation mark is next to the word Bluetooth.
- There is an "unknown hardware" in the list.
- In general, there are no similar sub-items.
- "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. It's just that Windows OS has nothing more to offer you.
To solve this problem, you need to install the driver and see if it helps. Download it from the site that represents your laptop model.
You can find the site by typing in the search engine the phrase "Laptop_model support". If the required driver is not available, apply 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 new software.
Often, the representative's website offers not one, but several drivers for one version of the adapter.
In order not to make 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 "Hardware ID". You will need the last line from the "Values" field.
Copy it and paste it into the search engine at devid.info. The system will sort the drivers that are the most suitable.

Reasons why Bluetooth does not work on Android

If there are problems in the operation of the device on the phone. The very first thing to do is determine the nature of the problem.
It is necessary to understand whether it is activated or not, does the problem occur already when the device is turned on or does it not work in principle?
Adapter does not turn on
If the device as a whole does not activate in any way and shows a constant load, the cause of this incident is a hardware malfunction, system malfunction, a virus in the phone, or a program with which there was a conflict is installed.
To fix the problem, try rebooting your phone.
This action would be appropriate if the problem was lack of space due to an overabundance 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, overwrite this data on another media before resetting the settings.
In order to perform a full reset, you should follow the following algorithm of actions: “Settings” / “Reset settings”.
If, after performing this option, the problem does not disappear, then the device is simply broken. The situation can be resolved only with the help of a service organization for the repair of equipment.
In the case when it does not turn on in a newly purchased phone, change it under warranty.
The mobile does not see the bluetooth device, but the adapter turns on
If this situation occurs, you need to check if Bluetooth is turned on.
Enable Bluetooth
If yes, then you need to enable the device visibility mode and disable the "Detection timeout" options. Now the device will work in the correct mode.
Adapter turns on but no data is being transferred
In the case when your mobile has an old version of the operating system, then its BT 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 app from the Play Market.
It is very convenient to use bluetooth to exchange information between your phone and a personal computer or to listen to music using wireless headphones.
But there are unpleasant situations when, after updating the bluetooth, Windows 10 does not see the device. What to do in this case? Let's consider the situation in more detail.
Bluetooth device and driver status
First you need to determine if your bluetooth is still in place after the update? Are the drivers installed and how well do they work?
To check if it is on the computer, go to the "Control Panel", in the "Device Manager" section.
There, one of the sub-items should be "Bluetooth". If it is present, do you need to check if the drivers are installed on it? To do this, click on the name with the mouse and open the contents of the folder.
It must have an investment. The main thing is that there would be 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 is shown next to the name.
To change the settings to "on", you need to right-click on the name and activate the device.
If, nevertheless, the drivers are not installed, in the device manager, in the “other devices” sub-item, an “unknown device” will be placed, which, most of all, is your adapter.
To solve this problem, you need to update the drivers and set the path to them.
There is another option when the device manager will not see anything related to bluetooth and unknown devices.
You need to double-check and make sure that the adapter is present on the PC at all. If not, you should purchase it from a specialized store and install it. The simplest adapter looks like this:
What does Bluetooth look like on the toolbar?
If the 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's not there, don't worry - it might just be turned off. Auto-shutdown is most likely inherent in 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 are using a laptop, you need to find a special key on the keyboard that turns the module on and off. In the case when you do not know where such a button is located, you can accidentally turn off the bluetooth all the time and puzzle over what is happening with the adapter.
The phone does not detect a headset to listen 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, there are problems with pairing.
This is because the phone is looking for the settings that were on the old phone. You need to properly configure the connection and the question will be settled.
After reinstalling Windows 10, 8 or Windows 7, or simply deciding one day to use this feature to transfer files, connect a wireless mouse, keyboard or speakers, the user may find that the Bluetooth on the laptop does not work.
Partially, the topic has already been covered in a separate instruction -, in this material, in more detail about what to do if the function does not work at all and Bluetooth does not turn on, errors occur in the device manager or when trying to install the driver, or it does not work as expected.
The first possible reason for the situation is a disabled Bluetooth module, especially if you often use Bluetooth, quite recently everything worked and suddenly, without reinstalling drivers or Windows, it stopped working.
Function keys
The reason that Bluetooth does not work may be turning it off using the function key (the keys in the top row can work while holding the Fn key, and sometimes without it) on the laptop. However, this can happen as a result of accidental keystrokes (or when a child or feline takes possession of the laptop).
If there is a key with an image of an airplane (Airplane mode) or a Bluetooth logo on the top row of the laptop keyboard, try pressing it, as well as Fn + this key, this may already turn on the Bluetooth module.
If you don't have airplane mode and Bluetooth keys, check if the same works but with a key that has a Wi-Fi icon (there is one on almost any laptop). Also, on some laptops, there may be a hardware switch for wireless networks that disables Bluetooth as well.
Bluetooth disabled in Windows
In Windows 10, 8, and Windows 7, Bluetooth can be disabled using settings and third-party software, which may look like "not working" to a novice user.
Laptop manufacturer's utilities to turn Bluetooth on and off
Another possible option for all versions of Windows is to turn on Airplane Mode or turn off Bluetooth using programs from the laptop manufacturer. For different brands and models of laptops, these are different utilities, but all of them can, among other things, switch the state of the Bluetooth module:
If you do not have the manufacturer's built-in utilities for your laptop (for example, you reinstalled Windows) and decided not to install proprietary software, I recommend trying to install it (by going to the official support page for your particular laptop model) - it happens that you can only switch the Bluetooth module state in them (with original drivers, of course).
Enabling and disabling Bluetooth in the BIOS (UEFI) of the laptop
Some laptops have the option to enable and disable the Bluetooth module in the BIOS. Among those - some Lenovo, Dell, HP and not only.
You can usually find an item for enabling and disabling Bluetooth, if available, on the Advanced or System Configuration tab in the BIOS in the Onboard Device Configuration, Wireless, Built-in Device Options items, while the value Enabled = "Enabled".
If there are no items with the words “Bluetooth”, look for the presence of the WLAN, Wireless items and, if they are “Disabled”, try also switching to “Enabled”, it happens that the only item is responsible for enabling and disabling all laptop wireless interfaces.
Installing Bluetooth drivers on a laptop
One of the most common reasons for Bluetooth not working or turning on is lack of required drivers or inappropriate drivers. The main signs of this:
Note: if you have already tried to update the Bluetooth driver using the Device Manager ("Update driver" item), then you should understand that the system message that the driver does not need to be updated does not mean that this is really the case, but only informs you that Windows cannot offer you another driver.
Our task is to install the necessary Bluetooth driver on the laptop and check if this solves the problem:
Often, several different Bluetooth drivers or none can be posted on official sites for one laptop model. How to be in this case:
In the list at the bottom of the devid.info search results page, you will see which drivers are suitable for this device (you do not need to download them from there - download them on the official website). More about this method of installing drivers:.
When there is no driver: this usually means that there is a single set of drivers for Wi-Fi and Bluetooth for installation, usually placed under a name containing the word "Wireless".
With a high probability, if the problem was in the drivers, Bluetooth will work after they are successfully installed.
Additional Information
It happens that no manipulations help turn on Bluetooth and it still does not work, in such a scenario the following points may be useful:
Perhaps this is all I can offer on the topic of restoring Bluetooth functionality on a laptop. If none of the above helped, I don’t even know if I can add something, but in any case - write comments, just try to describe the problem in as much detail as possible, indicating the exact laptop model and your operating system.
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 turn on Bluetooth in Windows 10, how to find the settings, and what to do if Bluetooth on a laptop does not work, there is no power button, and there is not even a Bluetooth adapter in Device Manager.
If you do not 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 there is a Bluetooth adapter in it. It's just a driver issue. After all, if Windows 10 could not 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 a laptop, you will see that there is no power button and the "Bluetooth" section itself in the Windows 10 settings. What to do in such a situation, we will also consider in this article. So that you do not get confused, we will do everything according to the following scheme:
- Turn on bluetooth on laptop
- Consider Bluetooth options 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, it is necessary to use the key combination Fn + F2, Fn + F3, etc. To be honest, I don’t understand where such information comes from. I have an Asus laptop, when I press the Fn + F2 keys (F2 with wireless icon) Simply turn on and turn off airplane mode. It is clear that for Bluetooth to work, the "on the plane" mode must be disabled. If everything is different on your laptop, write about it in the comments.
Everything is much easier. We click on the notification center icon, and we see a button there Bluetooth. Click on it and it will turn blue. This means that Bluetooth is already enabled. To turn it off, press this button again.
That's all 🙂 You can connect devices, for example,.
If you do not have such a button, as I have in the screenshot above, then most likely the adapter is disabled, or the driver is not installed. How to solve this problem, read at the end of this article.
Bluetooth device management, connection, setup
To open the settings, view available and connected devices and enable the discovery of your laptop by other devices, just right-click on the Bluetooth enable button and select Go to options.
A window with options will open. The laptop will search for Bluetooth devices and display them in a list. You can connect with these devices. Just select the desired device, 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 their laptop will detect them. And if this is, for example, a smartphone, then it can be hidden from the search, and Windows 10 will not see it. This is all turned off 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 box Allow Bluetooth devices to discover this computer, then all devices will not be able to see your laptop. But, you will see them, and you will be able to connect to them.
Also, immediately after turning on, an icon will appear on the notification panel. By clicking on which, you can quickly go to different settings: adding a new device, sending / receiving files, going to settings, etc.
Here are the settings. You can easily connect new devices and manage them. You are unlikely to transfer files, but wireless headphones, acoustics, mice, etc., are very convenient.
Bluetooth not working in Windows 10. No power button
So, if your laptop does not have any signs of Bluetooth (there is no power button, and there is no section in the parameters), then most likely:
- Adapter driver not installed.
- The adapter is disabled and therefore Bluetooth is not working.
- Or it is not installed at all in your laptop.
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 next to the adapter (in the form of an arrow), then right-click on it and select Engage.
After that 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 should be for Windows 10. In the manager, you will most likely have at least one unknown device, on the tab Other devices.
You can download the driver from the official website of your laptop, and it is required 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 that this is a rarity, since the "ten" usually installs drivers for wireless modules by itself. In extreme cases, you can use the program to automatically search for and install drivers. After installing the driver, in the device manager you should have something like this (your names may be different):
If nothing is clearly indicated on the stickers, and the packaging has not been preserved, look for information on the laptop manufacturer's website or ask a question to the support service.
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 identify it by the Blue Tooth logo icon. On others, a combination of pressing Fn and one of the function keys (F1-F12). To determine exactly where to press, the symbols on the keyboard will help.
On some laptops, such as the MSI X460 DX, a separate key is allocated to enable bluetooth:
On others, more often, it is combined with the Wi-Fi power button:
After the adapter is activated, the Blue Tooth indicator on the case will light up (if there is, not all devices are equipped with it).
Personal computers can be seen in almost every home today. But they were replaced by laptops. These are compact analogues of stationary PCs, which are much easier to work with. Most laptops are equipped with a variety of useful programs, applications and devices. For example, Bluetooth. This feature allows you to synchronize phones and other gadgets with a computer at a distance without any wires, which greatly simplifies life. But sometimes people have to wonder why bluetooth does not work on a laptop or desktop computer. We will have to deal with this issue further. In fact, the reasons for this phenomenon may be different. Often the situation is corrected without much hassle, and the main problem is diagnosing what is happening with the PC.
Types of Bluetooth
Bluetooth is different. The type of connection standard used will determine the speed of data exchange.
Today you can find the following types of bluetooth:
- 1.0 is the oldest version of Bluetooth. Not used on modern devices. Transfers data very slowly and compromises the security of information.
- Bluetooth 1.1 - has support for non-encrypted channels and indication of the level of the transmitted signal. It also almost never occurs in real life.
- Bluetooth 2.0 is a type of bluetooth that is in great demand. This type of connection appeared in 2007 and has since proven itself perfectly. There is optional support for EDR to increase the speed of data exchange. Security and compatibility have also been greatly improved.
- Bluetooth 2.1 is an improved version of the previous "assembly". In this Bluetooth, you can update the encryption key without disconnecting the connection. "Model" is equipped with energy-saving technologies.
- Bluetooth 3.0 + HS - version released in 2009. It has support for high-speed data exchange (up to 24 Mbps). Among the disadvantages are the high energy costs during Bluetooth operation.
- Bluetooth 4.0 - consumes little energy due to intermittent signal transmission. Here the receiver is always "ready", but it starts working only when data is transmitted. The technology is being actively introduced into a variety of equipment, especially sports equipment.
Now it is clear which Bluetooth can be encountered in practice. But why doesn't bluetooth work on a laptop? How to correct the situation in this or that case?
Main causes of the problem
As already mentioned, users may encounter various causes of bluetooth failures. Consider the most common scenarios for the development of events.
Bluetooth not working on laptop? Here is a list of the most common reasons why this happens:
- the technology is completely absent on the laptop;
- the user forgot to enable the option on the PC;
- the user has not established synchronization with another device (incorrect connection of devices to each other);
- system failures;
- overcrowded PC registry;
- the presence of viruses and spyware on the computer;
- Bluetooth incompatibility on synchronized devices;
- laptop hardware is out of order;
- missing or corrupted/outdated hardware drivers on the computer;
- Bluetooth is disabled in Device Manager.
This is not a complete list of possible reasons for bluetooth failure to work. The listed layouts are simply more common than others. We will focus on them.
Lack of drivers
Bluetooth not working on laptop? This may be due to the lack of hardware drivers on the computer. This problem most often occurs on laptops with a "clean" operating system.
The absence of drivers can be checked in the "Device Manager". Having opened this service, the user should look at the Bluetooth sections. If there are none or an exclamation mark next to them, then there are no drivers.
You can fix the situation like this:
- Go to the Bluetooth equipment manufacturer's website.
- Download the driver for the device on the PC.
- Run the received file and wait for the software initialization to complete.
Now you can restart your computer and see the result. Most likely, the problem will disappear.
Old software
Why is bluetooth not working on a laptop? Sometimes this happens due to outdated software. Connected hardware and Bluetooth drivers need to be updated from time to time.
To cope with the task, the user can use the previously proposed instructions. Owners of Windows 7 and newer are able to update drivers through the "Update Wizard".
This will require:
- Connect the laptop to the network.
- Open "Windows Update Wizard".
- Check for updates.
- Find bluetooth and tick it.
- Select the "Download and Install" option.
- Wait for the download to complete and the software to initialize.
As soon as the bluetooth drivers are updated, you can resume working with the equipment. It is possible that the problem will be fixed.
Forgot to turn on
Bluetooth not working on laptop? Fortunately, sometimes the cause of this phenomenon is the carelessness of the user. Some simply forget to turn on Bluetooth on the laptop or on the device being synced.
- Turn on the computer and wait for it to fully boot.
- Press the Fn button on the keyboard.
- Find and press the key with the "Bluetooth" icon. Sometimes the button has an image of a gear line.
- Release the buttons.
An additional indicator lamp should light up on the laptop panel. It means bluetooth is on.
Lack of equipment
Why is bluetooth not working on a laptop? Not all laptops are equipped with this technology by default. If your device does not have a Bluetooth adapter, wireless sync will not work. This is normal.
You can find out about the availability of bluetooth when buying a laptop from a sales assistant. If desired, the user is able to find information about his laptop on various sites - it will definitely indicate whether Bluetooth is available by default or not.
If the equipment is not available, you will have to buy a special bluetooth adapter. It connects to the USB-connector, after which the software is configured.
Radio disabled
How to check if bluetooth is working on a laptop? It is worth paying attention to the information in the "Device Manager". Here the user will be able to see which devices are not working.
Before referring to non-working Bluetooth, you need to make sure that the technology radio module is not disabled. Turn it on if necessary.
The algorithm of actions will be as follows:
- Go to the "Device Manager" in any way known to the user.
- Open the "Bluetooth radio modules" section. Sometimes you need to open the "Network adapters" tab.
- Right-click on the relevant equipment.
- Select the "Activate" option.
If there is no corresponding function, then the radio module is connected. Accordingly, Bluetooth on the laptop works. We'll have to look for the cause of the failure elsewhere.
Laptop hardware failure
Bluetooth does not work for a user on an Asus laptop? It doesn't matter what kind of laptop a person has - the main thing is that problems with a wireless connection can occur on all laptops.
For example, if the device has been used for a long time, some components may wear out on it. Even those with whom they rarely work. For example Bluetooth.
How to check if bluetooth is working on a laptop or not? To do this, you can act like this:
- Enable Bluetooth technology on the laptop using the keyboard.
- Activate the corresponding option on the connected device. For example, on the phone. You can do this through the gadget settings.
- Go to "Control Panel" - "Hardware and Sound" - "Add a Bluetooth Device".
- Wait until the search for new devices is completed.
If the user used the technique several times and it did not work, you can carry the laptop to a service center. Most likely, the problem lies in the faulty Bluetooth hardware of the computer.
Important: if the user uses a bluetooth adapter, it will have to be replaced with a new one. Otherwise, the functionality of the option cannot be returned.
Viruses and Spies
Bluetooth not working on HP laptop? This situation can occur due to a virus infection of the PC. A fairly common problem, insufficient attention to which leads to serious consequences.
If all the previously listed tips did not help, it is recommended:
- Close all background programs and browsers.
- Open any antivirus and conduct a deep scan of the OS.
- Disinfect all potentially dangerous objects.
- Everything that did not succumb to the operation, delete or place in "Quarantine".
It remains to restart the computer and see what happens. If the operating system is cured, its services will be restored.
Important: after cleaning the OS from viruses and spyware, it is recommended to update the drivers.
Device incompatibility
Bluetooth not working on Asus laptop? If this situation occurs only in relation to individual devices, the reason may be the incompatibility of the devices.
Support for a Bluetooth connection should be studied immediately before buying a particular gadget. If it turns out that there is no bluetooth compatibility on the laptop, you will have to purchase a new device. There is no other way to solve the problem.
Connected device failure
Bluetooth speaker not working on laptop? Mobile phone does not want to sync?
If the problem does not occur on the same laptop, it's all about a malfunction of the connected device. Bluetooth doesn't work on phone or speakers.
The user is able to take the faulty gadget to a service center for repair work. If this does not help, you will either have to abandon the bluetooth, or buy a new device.
Computer registry
Bluetooth stopped working on laptop? Let's assume that there are no viruses on the computer, the software and drivers are up to date, all the devices involved are working. What then?
Maybe the PC registry is to blame. Its fullness often leads to system errors and crashes. All this negatively affects the operation of the OS as a whole. And bluetooth can be affected too.
Instructions for cleaning the computer registry will look like this:
- Download and install CCleaner.
- Open the program and in the menu on the left set the marks next to all sections of the hard disk.
- Click on the "Analyze" button.
- Wait for the diagnostic result.
- Click on the "Clear" button.
Once the operation is completed, you can repeat the work with the bluetooth device. It is best to restart your computer first.
Hardware and system incompatibility
Why is bluetooth not working on a laptop? Modern users are increasingly faced with the incompatibility of the equipment connected to the PC and the operating system. This phenomenon is most common among people working on Windows 10.
Hardware failure with the OS is not treated in any way. You can fix it:
- by reinstalling the operating system to a compatible one with the device;
- replacing the connected device with one compatible with the existing OS.
There are no more options for the development of events. Hardware and OS incompatibility can be avoided by carefully studying the system requirements of gadgets.
OS reinstallation
Bluetooth does not work on a Lenovo laptop or any other brand? Did the tips above help?
You can try to fix the situation by completely reinstalling the operating system. After that, the user will need to install Bluetooth drivers and try to synchronize devices.
Reboot and system crashes
We found out why bluetooth does not work on a laptop. If the user suspects a system failure while working with the OS, you can simply restart the computer.
