Bluetooth does not work on the computer what to do. How to enable bluetooth on a laptop under different versions of Windows. Bluetooth module hardware failures

Virtually every modern laptop is supplied wireless communicationlike Bluetooth. But, as with any components, equipment personal computerBluetooth may not work. This may be a consequence of a large number of reasons. However, in most cases, you can independently solve this problem without calling the wizard. So, why doesn't Bluetooth work on a laptop?

The main reasons why the connection may not work

If you have some time (maybe even once) used the services of this wireless type of communication, and then unexpectedly he stopped working and no longer sees the device, it means that you had one of the following problems:

  1. Perhaps you simply did not turn on the Bluetooth special switcher;
  2. The technology was disabled by any failure and is not involved in the device manager;
  3. After resetting the laptop settings, reinstall the system or any other operation that returns the device to the factory parameters;
  4. Accidental removal of drivers or under the action of the attack of viruses;
  5. Software or mechanical failures.

If you understand what the reasons described above suits you, you can immediately go to the appropriate item in troubleshooting solutions. However, we strongly recommend starting from the very first, because you can hardly know if you can hardly (if you, of course, are not a good specialist. Then why do you need help this article?). It will also help avoid other breakdowns in the system. Why? Consider a small example.

Suppose you worked perfectly with Bluetooth on a laptop pretty long time. But suddenly you had to reinstall the operating system on the computer. After a successfully done operation, you noticed that your favorite wireless technology stopped working. And you run for helping the third item in the category of problem solving. You reinstalled the drivers, but bluetooth work Not resumed. And then it turned out, Windows itself found the driver after reinstalling and you needed to simply turn it on through the device manager. So you got a new headache that you absolutely do not need.

So, if approximately we entered the subject of all that is happening, let's try to fix Bluetooth. First of all, make sure that you have an internet connection on your device. It will be needed if you have to reinstall drivers.

Ways to solve problems with Bluetooth

After each step, immediately check the work. If the problem persists, then go to the next problem of solving problems when Bluetooth disappeared.

  1. First, check: whether the switch on the laptop itself is enabled. On some models there is a special button, other technology is included in the key combination. Also see if the light indicator works that displays the availability of the wireless communication module. Most often, the red color means that it does not work, but blue, respectively, what works. But it depends on specific model laptop.

  1. If the switches do not work, then there is a problem with additional software for the key combinations. Their installation will be described below. If you can do it later, and now you urgently needed Bluetooth, we do the following. Go to "Device Manager". To do this, click "Start" and enter these words in the search field. Opening the necessary menus, we are looking for a Bluetooth radio module. There you will find the name of your module. Click on it right-click Mice and choose "Enter".
  2. To reinstall drivers, you will need the same sequence of work as in the previous paragraph. With the exception of the last action. By clicking the right mouse button, select Refresh Drivers. Following the prompts on the monitor, you download new drivers from the center windows updates. If it did not help, then you will need to independently install the driver package. How to do it below.
  3. If you have viruses on your computer, then you will definitely clean. Then restart the PC and check it again with an antivirus system. Only then go to download drivers. So, there are two options manual installation Package: Download from the Internet and installing with a disk. It happens that in a set with the device there is a drive with drivers. You will need only insert it into the drive and follow the instructions on the display. If there is no such, refer to the official site of the laptop manufacturer. In the "Drivers" section, select the model of your computer and the OS version. Then he will find the entire driver package for your device. You will need to download for Bluetooth and install them.

  1. It happens that all switches are turned on and PC indicates that the wireless communication module works fine. However, you still can't connect and Bluetooth does not see the device. First, check that the connected device (printer, smartphone, tablet) works in detection mode. Secondly, you can try to restart the laptop. Sometimes this happens enough.

Now you know what to do if the Bluetooth does not work on a laptop or it does not see the device. And even if after all the above operations, you could not configure the operation of the module, please contact a specialist. But in no case independently do not disassemble the laptop. Pleasant use, friends!

Bluetooth technology allows you to quickly send files from one device to another, it is especially convenient for the users of laptops, since they are limited to USB ports for flash drives and other memory devices. However, some owners of laptops appear problems with this technology, why is it going on and how to correct the situation?

To begin with, you should determine possible reasons Problems. For this:

These are the most common problems and errors associated with the incorrect recognition of the module, each of which has its own solutions.

The device is disabled

It happens that after downloading updates or restart modular system Bluetooth is simply turned off. This is not a problem, but only a hitch, because it is easy to turn on. Make it can be done different ways. For example, through Device Manager: Click on the adapter icon with the right mouse button and in the drop-down menu click on the item " Cyclingยป.

Or manually using buttons on the laptop panelIf there are such.

Each laptop has its own function keys, including Bluetooth. Therefore, it will be useful to familiarize yourself with the instructions.

Problem with drivers

Drivers are softwarewhich allows the device to work with a laptop. Drivers can "fly" after updates or complicated. You can correct the problem in several ways:

Most often, the problem is in the drivers, and their reinstallation corrects it and allows the device to function normally.

When defense system virus, File transfer technology may also be unavailable. In such a situation, you should first clear the system from malicious software and then try to enable the adapter.

It is impossible to completely eliminate the option physical damage (Closing contacts), especially if the adapter is not built-in. In this case, you will have to disassemble the device and change the items if necessary.

Bluetooth (Bluetooth - "Blue Tooth") is a special standard of wireless communication, i.e., using electromagnetic oscillations. It is used to connect two mobile devices and transfers between them. Initially, this technology was developed in order to ensure work wireless headset in mobile phonesWhat makes it possible to talk without hands (Hands Free). But this is not limited to the use of this technology in the laptop and other mobile gadgets - it can also be transmitted files.

For a long time known for another wireless standard - Wi-Fi. What is the difference between the new standard from Wi-Fi? Their main differences are:

  • Different frequency ranges.
  • Bluetooth has a smaller range.
  • When using bluetooth, there is no need to adjust the hardware configuration.
  • With this standard you can not configure local network, i.e. to connect more than two devices at the same time.
  • In the "blue tooth" the transfer rate is significantly higher.

As a rule, a wireless communication radio module has already been built in a modern laptop. But if it is not (or one of the subscribers is a desktop PC), you can buy an external adapter. It resembles a flash drive and connects to the USB port.

Find out if there is a built-in radio module in a laptop with Windows 7, and you can also see it and turn it on using the task manager. To do this, log in to the control panel, select the "Administration" item, open "Computer Management" in it, then select "Device Manager". If there is no "Bluetooth radio module" in the list of installed devices, it means that there is no bluetooth module laptop. If he is, but next to it is issued a question or exclamation mark, it means that the adapter drivers require updates or reinstallation, but this is a topic of a separate article. When buying an external adapter, it is usually attached by the CD with drivers. After the device driver is installed, Windows 7 will be detected, and the user will be able to make sure that similar actions.

Such a state in a laptop with Windows 7 may occur three reasons:

  • The radio adapter is turned off and it must be enabled.
  • The adapter is faulty.
  • Adapter drivers are not installed or need to reinstall.

We are only interested in the first case - when the corresponding adapter is turned off, and it is necessary to enable it. This can be done in several ways.

Standard way to enable Bluetooth

In the panel notification area windows tasks 7 There is an icon of this radio module.

To configure the adapter status, you need to click on it, the menu will appear. Next, click on the "Add Device" item.

With hardware

There are laptop models equipped with hardware shutdown / disable adapter buttons. If this is available, then it must be set to the ON position.

Enable using the FN key

Most laptops have a FN key on their keyboard. It is designed to manage the state of various equipment installed in the computer, including bluetooth. The top row of keys is the function keys (usually F1 - F12), pressing which along with Fn just performs such control. In the laptop, depending on its manufacturer, the key control key of the "blue tooth" can correspond to the various function keys, as a rule, this is F3-F5. This key must contain the corresponding icon.

Sometimes both wireless adapters Completed in one module, so they turn on and off simultaneously using such a function key.

Through device dispatcher

How to go to Windows Device Manager, has already been said at the beginning of the article. Entering into it, you can see a picture with a list of all installed devices.

We are interested in the "Bluetooth radio module". Open it, select the appropriate adapter and click on it with the right mouse button. If this module is turned on, then the "Disable" item will be present in the menu, otherwise - item "Enable". Here it is needed - we click on it, the adapter turns on.

Turning on the radio communication module by third-party utilities

Depending on the manufacturer, there are a number of third-party utilities, with which you can enable the radio adapter. These are such utilities like:

  • Wireless Console (ASUS laptops).
  • READYCOMM (Lenovo laptops).
  • UTILITY CENTER (HP laptops).

All of them are very easy to use, and they are easy to find on the Internet. After installing them in Windows 7, the Bluetooth logo icon appears in the notification panel. Right-clicking with the right mouse button, in which the Bluetooth adapter is the "Enable / Disable" element.

Using the command line

This method includes a radio component of communication more difficult than all described above, so it should be resorted to it only if none of the already given methods helped. For such an inclusion, you will need Devcon utility - it is easy to find it on the Internet and download. If it is downloaded in an archive state, the archive needs to be unpack. The program must be placed in the C: \\ Windows \\ System32 directory. In addition to this utility, a radio module identifier will also be needed. It can be found using the dispatcher windows devices 7.

In it, open the "Bluetooth Radio Module" item, Right-click on the desired module And in the menu that appears, select "Properties". A window will open in which you need to go to the "Details" tab, and select "Equipment ID" in the "Property" drop-down list. In the "Value" window, the first line and contains the ID of the selected radio module.

Next we enter the mode command line. To do this, press "Start", in the bottom of the search bar, enter CMD, opens a window, in the upper line of which is the value "CMD". Click on it, the window opens to enter the command line. In it, we enter a string of the type of DevCon Enable ID (without quotes). Instead of ID, you need to set the equipment ID device received from the device manager. Click ENTER, the DevCon utility is started, which includes a disabled radio module.

In contact with

The cause of the malfunction of such a device as Bluetooth may even be a banal incorrect setting. Therefore, it is not necessary to immediately get upset about this reason and flee for help from specialists, as it is often a similar problem can be solved on their own.

Clarification of the cause

For example, if Bluetooth worked properly for a long time, and then disappeared, there may be several reasons for this: reinstalling the operating system, failure or incorrect setting Drivers of this device, failure in the operation of mechanical switches, as well as malfunctions in the work of the laptop itself, etc. To identify a specific reason for the appearance of a malfunction and subsequent elimination, it is necessary to find out whether Bluetooth is enabled. You need to see if the Bluetooth indicator is on on the device.

If the indicator is on and Bluetooth is running, but it does not work anyway, then you need to check the drivers. Go to the "Start" menu and open the control panel. Here you need to find item " Bluetooth devices" If the system indicates that the "Bluetooth device" is not found or does not work, then it will be necessary new installation Drivers. Typically, the drive disk comes with a laptop or an external adapter. In the event that there is no such disk, the drivers can be found on the manufacturer's website, download and install them from there. If the installation did not help, then most likely, the problem is directly in the Bluetooth adapter and solve this problem can only be purchased new.

Troubleshooting

Quite often the problem is new version operating system. Sometimes, after reinstalling the OS, they can remain, but they will not work with the new operating system. To solve grocery problemYou will need to first remove old drivers, and then install new from the manufacturer's website. To delete, you need to go to the "Control Panel" again and find the Bluetooth Device icon. After clicking, a list of devices will appear where the integrated module will be removed. After deletion, you need to restart the computer and give the system to install drivers for the device yourself. If this does not happen, then you need to go to the official website of the laptop manufacturer or Bluetooth adapter, specify the version of the operating system with which you work, and download drivers, which then need to be installed on your own.

If none of these methods solved the problem, then, most likely, it consists in the adapter itself and it will need to be replaced with a new one. Fair to find them now is not difficult in a special computer store.
