Personal computers can be seen today in almost every home. But they were replaced by laptops. These are compact analogs of stationary PCs, which are much easier to work with. The majority of 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 the bluetooth does not work on a laptop or on a desktop computer. We will have to figure this out further. In fact, the reasons for this phenomenon may be different. Often the situation is corrected without much hassle, and the main problem is the diagnosis of what is happening with the PC.
Bluetooth views
Bluetooth is different. The speed of data exchange will depend on the type of connection standard used.
Today you can find the following types of bluetooth:
- 1.0 is the oldest version of Bluetooth. On modern devices is not used. Transmits data very slowly and compromises information security.
- Bluetooth 1.1 - has support for non-encrypted channels and indication of the level of the transmitted signal. Also almost never found in real life.
- Bluetooth 2.0 is a type of bluetooth that is in great demand. This kind of connection appeared in 2007 and since then has proven itself perfectly. There is optional EDR support 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 "build". In this Bluetooth, you can update the encryption key without disconnecting the connection. "Model" is equipped with energy-saving technologies.
- Bluetooth 3.0 + HS - the version was released in 2009. It has support for high-speed data exchange (up to 24 Mbps). Among the shortcomings emit large energy costs when working with Bluetooth.
- Bluetooth 4.0 - consumes little power due to intermittent signal transmission. Here the receiver is always at the ready, but it only starts to work when transmitting data. The technology is being actively implemented in a variety of equipment, especially in sports.
Now it’s clear what Bluetooth can be found in practice. But why does bluetooth not work on a laptop? How to fix the situation in a particular case?
The root causes of the problem
