There are many reasons why your keyboard may not work well or may not show any signs of life at all. First, you need to immediately determine the root cause of such a breakdown: software or hardware. Speaking in simple language- either the keyboard itself is faulty, or the problem lies in the Windows settings.
So, in order...
The keyboard works, but some keys do not work well (stick, do not respond to pressure, etc.).
The reason is usually simple - the keyboard is dirty.
You need to disassemble the keyboard and clean it. It doesn’t matter what kind of keyboard you have (usb, standard, wireless, built into the laptop). Turn the keyboard over and unscrew a few screws. Here you will see that under each button there is a rubber pad. Sometimes it happens that the lining breaks or “slips” out of place.- as a result, the corresponding key does not work. Then you just put everything in its place.
The key buttons can be wiped with anything, any cleaning agent. But it’s better not to touch the translucent film and everything else. By the way, so as not to get confused later about where each key should be, take a photo of your keyboard in advance. Of course, you can then find your keyboard model on the Internet and arrange the keys. But, still, it is much more convenient to take a photo of your keyboard. Some even number the keys in pencil to avoid confusion later. After “cleaning”, arrange the keys in their places, place the rubber pads (they can be placed in any order - they are all the same). The work is painstaking, but the result will be a perfectly working keyboard.
Plug problem
If you have a classic keyboard (with a round purple plug), then sometimes it happens that the small legs of the plug can bend.
In general, this type of connector is called PS/2. Purple is for the keyboard, green is for the mouse. If you forcefully try to insert the plug, the legs may bend. Then you need to take tweezers (or small pliers) and straighten all the legs.
USB keyboard
This is a regular keyboard, but it is connected not to the PS/2 connector, but to the USB connector.
If such a keyboard does not work when connected, then the problem most likely lies in the BIOS settings (SETUP). When you start the computer, press Del (or F6, everyone has different keys).
And since in bios settings If you can’t use a mouse, then a reasonable question arises: “How can I press Del at startup, and how will I configure the bios if my keyboard doesn’t work???!” The problem can be solved simply - go to your neighbor and ask him for a keyboard for 5 minutes :)
Wireless keyboard
I’ll ask you a stupid question: “Have you charged your keyboard?”
Surprisingly, the battery usually just runs out and people forget to recharge it.
And it also happens that Windows simply cannot install drivers for your wireless keyboard. Then search for drivers on the Internet manually.
Drivers
It happens that some new installed program unknowingly corrupts keyboard drivers. If you have Windows 7 installed, then driver problems should not bother you. The system itself installs and restores drivers. Usually, you just need to restart your computer.
But there are times when the driver is damaged, or new driver doesn't work well. In such cases, you can proceed in two ways. First, restore the system to the day when the keyboard worked properly. Secondly, you can go to the device manager and update the drivers, or view their properties by looking at the diagnostics.
Keys don't work specific program or game
You should find the program or game settings and look at the key assignments. In general, study the settings. In games, as a rule, keys can be reassigned. And in programs, look at the list of hot keys.
Some other tips
If, when you turn on the computer, it makes three long beeps (beep, sound), this means that you have inserted the keyboard incorrectly. Simply pull out the plug and reinsert.
If the keyboard suddenly does not work, first of all, check it on other computers. If you only have one computer (usually everyone does), then go to your neighbor and check the keyboard on his computer.
Sometimes it happens that the mouse (computer) starts to work poorly - it jams and freezes. The mouse will constantly seem to be disconnecting and connecting (at the same time the computer will make sound signal about connecting the device). Due to the fact that the computer will constantly recheck the input devices connected to it, the keyboard will also begin to work poorly. Then just pull out the mouse and recheck the keyboard.
There are also cases when the mouse and keyboard cannot work at the same time. This happens EXTREMELY rarely, but it can happen. Somehow, some mouse models are simply incompatible with some keyboard models(?!). I personally encountered such a case only once. Usually you can fool the computer in this case. You need to find the mouse or keyboard in the registry and assign different names to them. Sometimes this helps... For the same reason, joysticks (gamepads) may sometimes not work in games. For example, the game allows you to use gamepads only from Microsoft, and the rest simply do not work. Then you need to find your gamepad in the registry and rename it to Microsoft.
If the keyboard does not work, and you still need to find something on the Internet (for example: drivers for the keyboard), then you can use the on-screen keyboard.
That's all. Ask questions - I will be happy to answer them.
Thank you for your attention!

Sometimes it happens that PC users are faced with the following situation: when they turn on the computer, the keyboard does not function. Everything seems to be connected, but the buttons do not respond to pressing. When the device is rebooted, the keyboard works, but only in the BIOS. As soon as the download starts, it turns off again and shows no signs of life. In addition, a warning may appear on the screen asking you to select safe mode, and simply pressing the F8 button does not produce any results.
The first thing that comes to mind is to replace the keyboard. However, there is no need to rush. If the problem is not in the part itself, then the new one will react in exactly the same way when loaded, or rather, not at all. So check other potential causes first.
It may not be the keyboard at all, but a tricky Windows setup. As a rule, most users today use USB devices; others are no longer produced. In this case, the problem is related to the BIOS disabling support for your keyboard when the system boots.
What went wrong and how to fix the situation?
Such troubles arise precisely because of an OS failure. When you turn on the computer, the system stops responding to the device that previously connected automatically, and as a result, the keyboard does not work. In other words, the operating system simply “does not see” the device.
But don't despair. The recipe for correcting the situation is much simpler than it might seem at first glance. You need to make sure that the keyboard is working and connected. Otherwise, everything that will be discussed further will not work. In this case, you will still have to look for a replacement. First, try reconnecting the keyboard to a different port. If it doesn't help, move on.
The next step is to enter the BIOS. To do this, hold down the Del, F1 or F2 key (on different devices The menu is entered using different buttons, most often Del). Hold down the desired key for a few seconds.
On the blue screen you need to find the menu item associated with our keyboard. It is usually called USB Keyboard Support, and on some models may be called Legacy USB Support. In this case, there will be a note next to the item indicating that the option is disabled. To activate the keyboard in the BIOS, just switch to Enabled mode. Don't forget to save your settings. To do this, press the F10 key and confirm your changes. Now restart your computer and check the result. The keyboard now works normally.
With a problem broken keyboard Anyone can do it on a desktop computer. The solution is to replace the device with a new one or connect the non-working device to another connector. Alternatively, by opening the keyboard case, you can try to clean it from dust and small particles. But what to do if your laptop keyboard fails? This article will look at the reasons and methods for resuscitating the main input device on a laptop PC.
All problems associated with the keyboard can be divided into two groups: software and hardware. In most cases, there are malfunctions in the operation of the software (errors in the system registry, input device drivers). Such problems are solved using the functions of the OS itself. A smaller group are hardware problems, which usually require contacting service center.
Reason 1: Sleep and Hibernation modes
Many users, instead of shutting down the PC, often resort to such useful functions, How "Dream" or "Hibernation". This, of course, significantly reduces Windows boot time and allows you to maintain the current state of the system. But too frequent use of such opportunities leads to incorrect operation resident programs. Therefore, our first recommendation is a regular reboot.
Users of Windows 10 (as well as other versions of this OS) who have it installed by default will need to disable it:
- Click on the button "Start".
- Click on the icon on the left "Options".
- Choose "System".
- Go to the section "Power and sleep mode" (1).
- Next, click "Advanced system settings" (2).
- Going to the power settings, click on the inscription "Actions when closing the lid".
- To change additional parameters, click on the top link.
- Now we need to uncheck "Turn on quick start» (1).
- Click on "Save changes" (2).
- Reboot the computer.
Reason 2: Incorrect OS configuration
First, let's find out whether our problems are related to Windows settings, and then consider several solutions.
Keyboard test on boot
The functionality of the keyboard can be checked when the computer boots up. To do this, simply press the function access keys in the BIOS. Each laptop model has specific keys, but we can recommend the following: ( "ESC","DEL", "F2", "F10", "F12"). If you manage to enter the BIOS or call up any menu, then the problem lies in the configuration of Windows itself.
Enabling "Safe Mode"
We check whether the keyboard works in safe mode. To do this, follow the links below to see how to boot a computer without third-party resident programs.
So, if the system does not respond to key presses at startup and in safe mode, then the problem lies in a hardware malfunction. Then look at the last section of the article. Otherwise, there is a chance to fix the keyboard using software manipulations. More on setting up Windows.
Method 1: System Restore
"System Restore"- it's built in Windows tool, allowing you to return the system to its previous state.
Method 2: Checking Drivers
Method 3: Removing resident programs
If the laptop keyboard works in safe mode, but refuses to perform functions in standard mode, it means that a certain resident module is interfering with the normal functioning of the input device.
The steps described below are recommended if the previous methods did not produce results. The input device is not working, but it is still possible to send a command to the system. For this we will use "On-screen keyboard":
Reason 3: Hardware faults
If the methods described above do not help, then the problem most likely has to do with the hardware. Usually these are loop violations. Generally speaking, opening the laptop case and getting to the ribbon cable is not a problem. Before you disassemble your computer, make sure it is eligible for warranty. If yes, then it is not worth violating the integrity of the case. Just pick up your laptop and take it to warranty repair. This is provided that you yourself complied with the operating conditions (did not spill liquid on the keyboard, did not drop the computer).
If you still decide to get to the cable and open the case, what next? In this case, carefully inspect the cable itself to see if there are any physical defects or signs of oxidation. If the cable is fine, just wipe it with an eraser. It is not recommended to use alcohol or any other liquids as this may only degrade the performance of the ribbon cable.
The biggest problem may be a faulty microcontroller. Alas, there is nothing you can do here yourself - a visit to the service center cannot be avoided.
Thus, restoring the operation of a laptop PC keyboard consists of a series of actions performed in a certain order. First of all, it is determined whether the malfunction of the device is related to third party applications. If this is the case, then the considered methods for setting up Windows will eliminate software errors. Otherwise, hardware intervention measures are required.
Keyboard - main tool for entering information, without which work on the computer is impossible. Most often, for this device to work flawlessly, you just need to connect it to a computer, and that’s it. necessary drivers it will install automatically. This happens in most cases, but not always. There are situations when, when you connect a keyboard to a USB or PS/2 connector, it is not detected on the computer and does not show any signs of operation - the indicators do not light up and the buttons do not work. In this article, we offer instructions on what to do if the keyboard on your computer does not work.
We recommend reading:
Connecting the keyboard to the computer is as simple as possible - just insert its wire into the corresponding connector on the motherboard, and after that the device will start working. There are wireless keyboards, the radio receiver from which is inserted into the USB connector, after which the device works if the distance between the transmitter and the device is maintained.
Due to the simplicity of the process of connecting a computer, we can conclude that there are only 2 reasons why the keyboard does not work on the computer:
- Mechanical. There may be problems with the keyboard itself or the wire that connects it to the motherboard. The cause of the malfunction may also be a broken connector on the motherboard.
- Software. Keyboard drivers are installed automatically, but during the installation process any software failures may occur and this situation not an exception. In addition, problems may not be observed at the level operating system, and in the BIOS, where the corresponding settings for the keyboard are disabled.
Depending on which connector the keyboard is connected to the computer, we offer different options for solving problems that arise.
What to do if the keyboard does not work on the computer via USB protocol
The most common interface for connecting a keyboard to a computer is USB. Information transfer rates from peripheral device The computer has enough both via the USB 2.0 and USB 3.0 protocols, so there is no difference in which connector the keyboard is connected to.
If the USB keyboard does not work when you turn on the computer, you need to do the following:
It is worth noting that users whose keyboard is connected to the motherboard via USB may have problems entering the BIOS on the computer boot screen if using old version basic software. In this case, you need to find a keyboard with a PS/2 connector or use the appropriate adapter.
What to do if the keyboard does not work on your computer using the PS/2 protocol
Keyboard manufacturers are trying to move away from the PS/2 connector, abandoning it in favor of USB. It is very difficult to find a keyboard with a PS/2 connector on sale, but if you come across such a peripheral and it does not work with booting Windows, most likely the problem is related to the drivers. To make the keyboard work, you need to do the following:
It is worth noting that a similar problem with keyboards connected via the PS/2 protocol most often occurs due to an error when installing the i8042prt.sys or kbdclass.sys driver.
Don't panic if the keyboard on your laptop doesn't work. What to do in such a case? In many situations, getting rid of this problem can be quite simple. In this case, the brand of the device used does not matter. The reason that caused this breakdown can be completely different: the most basic or quite serious.
Reason 1: the microcircuit burned out
The main reason, which is difficult to foresee in advance, is when the microcircuit burns out. First of all, you should check the touchpad, as well as the ports that are located around the perimeter of the device. It is important to pay special attention to the USB and RJ-45 connector (for cable). When they are not working, you will need to contact a service center. If the warranty period has not yet expired, you must request a replacement. Only a person who has relevant experience in this field can get rid of such a problem.If the ports are in working condition, we can hope for a positive outcome. The most common reason may also be the cable that provides the connection motherboard to the keyboard. In such a situation, in order to open access to the socket, it will be necessary to disassemble the laptop. The keyboard is secured using latches, which should be slightly pryed using a plastic card and then removed required module.
Appearance:
In disassembled position:
- connector for connection;
- plume.
Reason 2: inattention
This item will be useful for owners of a separate digital block.His appearance:
When there are numbers on the keyboard inoperative, the reason is user inattention of this device. Some of them, due to their negligence, often press the button Num Lock, which ensures the operation of this block - turns it on and off.
When numbers do not appear on the screen, but the cursor simply moves, you should press this key again. In this case, the indicator should light up, which confirms the working status of the function. It should be taken into account that in certain laptop models, for this purpose, a combination of keys is provided, such as: Fn + Num Lock.
Reason 3: viruses and driver failure
When the breakdown is not related to the hardware, then you should look for it in the software area. Some viruses act in such a way that they can “destroy” the keyboard driver. To check whether this assumption is correct, you should scan your system for the possibility of spyware. After the reboot process, you need to put the drivers in place. In many situations, these actions bring positive result.What to do when the driver does not want to install or return to working condition? Sometimes it is not possible to remove it in the usual way. In order to get the result, you can try to turn on the keyboard on the device using safe mode.
For these purposes, it is necessary to reboot by periodically pressing F8. With its help you can call up the selection menu additional ways downloads. In it you need to select the usual “safe mode”. When the OS starts, you should follow the steps described below.
You need to try to remove the problematic utility or click on “Roll Back”. The last action can bring results in a situation where a driver update was previously carried out, which affected the performance of this device. After this, the previously valid software version must be restored.
Steps to remove:
Open “My Computer” and then click on “Properties”.
We go to the “Dispatcher” and select a special section with a keyboard.
It looks like this in the screenshot:
Right click Press the mouse on the keyboard and open the “properties” item.
If the driver update is incorrect, click on “Roll Back”. In a situation where the system does not see the keyboard, click on “Delete”. For the latter option, you must have the original drivers on hand, which are provided by the manufacturer of this equipment.
Reason 4: features of some models + prevention
When releasing devices, some manufacturers try to ensure the ideal quality of their work. As a result, when the battery charge is low, certain parts, including the keyboard, may stop working. To restore its full functionality, you need to connect the laptop to the network.Users who prefer to eat while working should be sure to clean the keyboard from crumbs. To do this, you can use a can with compressed air inside. Thanks to the high pressure, small particles of food that get into the cracks and grooves will be quickly removed. It should be remembered that under no circumstances should you use a damp cloth or screwdriver to get rid of them.
In order to get rid of the problem with a non-working keyboard, you need to carefully read the instructions described above. Initially, you can try to find a way out as a result of checking software system for the presence of viruses, etc. Quite often, spyware is hidden behind system files and disrupts the full operation of the device.
In addition, a combination of keys such as Fn + NumLock, which brings the number pad into operation, can also help. The installation of additional drivers taken from unknown sources can also be considered as a cause of failure. You should be careful when installing software utilities such as MKey, which provide button reassignment. In some situations, the system may perceive them as a threat and exit the working state.
In any case, if these problems arise, you should not despair and immediately buy new laptop. If necessary, you can find a way out of this situation by connecting a stationary keyboard via the USB connector.
