Every PC user will sooner or later face certain problems. Most often, they relate to connected devices. For example, with the failure of the keyboard from work. This phenomenon does not occur too often, but it does occur. Today we will figure out why the computer does not see the keyboard and mouse. What actions need to be taken to restore the functionality of these devices? How dangerous is the problem being studied for the PC? Having answered all these questions, it will be possible to say with confidence that the failure of the keyboard to work will no longer be a hassle!
Device types
First you need to understand that today you can meet several types of studied devices. Depending on the type of keyboard, the algorithm for solving the problem will change.
To date, the following devices are distinguished:
- USB keyboard (wired);
- wireless models;
- with PS / 2 jack.
The first two keyboards are universal. They can be connected to any PC and laptop. The latest device is considered obsolete. It usually connects to desktop computers.
Causes of problems
Does the computer not see the keyboard? Why is this happening? The reasons for this phenomenon are many. Predicting them is very problematic.
Nevertheless, among the main causes of the failure studied are:
- missing / damaged drivers;
- the need to update the keyboard / mouse driver;
- incompatibility with OS and other connected devices;
- mechanical damage to the connectors;
- keyboard malfunction;
- damage to nests;
- PC virus infection.
Next will be considered in more detail the action algorithms in a particular case. What to do if the computer does not see the keyboard?
Driver issues
Let's start with the most common problem - missing, crashing, or outdated drivers. It is this software that gives users a lot of trouble.
You can check for the driver through the device manager. To do this, you need to click on the "My Computer" icon with the right mouse button, then select "Properties" - "Device Manager". Now you need to go to the "Keyboards" item and look at the connected devices that appear.
If there are no keyboards in this window, then the PC really does not see them. There are no drivers on the computer. Otherwise, double-click on the line with the connected device and go to the "Drivers" section. To update them, the user will have to click on the appropriate button. To translate ideas into reality, you must first connect the Internet.
Does the computer not see the keyboard? In this case (if the device does not appear in the dispatcher), you will need to go to the device manufacturer’s website, select the keyboard / mouse model there and download drivers. After that, install them by running the downloaded software package. The problem should disappear.
Incompatibility
In some cases, the computer does not see the mouse and keyboard due to their incompatibility. Similar situations are rare, but they do occur. It's no secret that all PC devices have their own system requirements. Non-compliance with them leads to malfunctions of the devices. Software conflicts with a peripheral device and is not recognized.
Incompatibility cannot be fixed. The maximum is to change your operating system or replace an incompatible device. Only in this way will the mouse and keyboard work.
Damage
But that's not all! Does the computer not see the keyboard? If the user is sure that the device is compatible with the operating system used, and there are drivers on the PC, you will have to look for the problem elsewhere. For example, in the device itself.
To prevent damage, the user must:
- check the integrity of the nests;
- make sure that the cable (if any) is intact;
- double-check the correct connection of devices.
If any damage is found, you will either have to bring the PC and keyboard for repair, or use new connectors to connect, or buy new peripherals. Damage in practice is quite common, but it is not difficult to fix them.
Viruses
Does the computer not see the keyboard? It is possible that there are some viruses in the operating system. Not a single user is insured from them.
What to do? Need to:
- Scan your PC for viruses. This requires an antivirus program. You can pay attention to Dr. Web or NOD32.
- Scan your computer for spyware. SpyHuter will cope with this task.
- Try to cure all potentially dangerous objects. This operation is performed by clicking on the "Cure" button in antiviruses.
- All that could not be treated must be deleted. To do this, there will be separate controls in antivirus and spyware programs.
Once all of the above steps are completed, you can restart the PC and watch what is happening. Most likely, the PC recognizes the mouse and keyboard. If this does not happen, it is recommended to reinstall / update the drivers.
About connection
Many are interested in how to connect a keyboard to a computer. In most cases, this is easier than it seems. Especially when it comes to wired models.
All actions must be performed with the PC turned off. Next, the user simply needs to take the wire from the keyboard and connect it to the appropriate connector. For example, a USB keyboard requires connecting to a USB jack. It is very convenient! The same should be done with devices such as PS / 2.
You will have to act a little differently when it comes to wireless devices. In this case, many people think about how to configure the keyboard. Typically, these devices do not require additional configuration, they begin to work immediately after installing the drivers.
Connecting wireless keyboards and mice is as follows:
- Insert the battery (batteries) into the device.
- Connect special receivers to the PC. They need to be connected to the USB port.
- Turn the switch on the keyboard to the on position.
- Turn on the computer. Activate Bluetooth on it.
- Wait for device synchronization.
That's all. Now it’s clear how to configure the keyboard on the computer with a wireless connection. Everything is much simpler than it seems.
findings
We figured out why the computer does not see the keyboard. It is worth noting that there are many options for the development of events. Most of them come down to either buying a new device or reinstalling drivers. Only in some cases, the keyboard failure to work is a sign of serious problems.
Any device has its own life. And it must be taken into account when connecting to a PC. Typically, wear and tear on keyboards when used actively occurs 5 years after they are purchased.
Incompatibility of software with the device is faced mainly by users of old OS and new devices. Also, a similar problem is now encountered on computers with Windows 10.
