The keyboard does not respond to key presses. The keyboard does not work, what should I do? Some keyboard shortcuts don't work
Hello everyone, dear friends. Quite recently, a strange situation occurred at my work, as it seemed to me. The keyboard just stopped working. Or rather, it didn’t completely stop. As it turned out, the keyboard only works in the BIOS, and upon further boot it simply stops responding to any presses.
And then an unpleasant situation occurred, or rather a failure. After the reboot, I had to select the boot mode, but I could not do anything, since none of the keys responded. First of all, I thought that it was the keyboard’s fault, after which I replaced it with a new one, but it turned out, but after I I installed another device, the situation did not change.
In general, I won’t bore you. Most likely you used a USB keyboard, since no one had such problems with PS/2. The thing is that your BIOS disables USB keyboard support when Windows boots.
"How so? After all, everything worked before,” you say. Yes, indeed, everything could work for you, and you could not notice anything, because when loading operating system it will automatically enable this support. But once a crash happens and you need to do something during the loading screen, then unfortunately there is nothing you can do.
What to do then? I want to say right away that the first thing you need to do is check the simplest thing that can only come to your mind, because sometimes the problem can really be somewhere on the surface. Therefore, first check whether the keyboard cable is connected to the computer, try moving it to another USB port, and if possible, connect another keyboard.
If none of this helps, then more likely it's a matter of setup. You need to login BIOS, namely at the very beginning of booting your computer, press function key responsible for entry. Most often this is the key DEL, but in different cases it could be F1, And F2.
As a result, when you get into the BIOS itself, depending on you depending on the version, you will need to find an item related to USB keyboard support. It may be called "USB Keyboard Support" or "Legacy USB Support". If you see that the “Disabled” mode is next to these items, then support is disabled and you need to activate the “Enabled” mode.
After that, save all the settings, reboot and voila.
As a rule, it is this setting is the solution to this problem. Although I heard that someone this decision did not help, and he decided to try to look for the problem in the components. It turned out that one bar random access memory was not quite working (in his words) and when he pulled it out, the keyboard started working normal mode. I don’t know how this is connected, but if something happens, you can try this method.
Well, I’ll finish here. I hope you liked my article. And if you still haven’t subscribed to my blog updates, be sure to do so now so as not to miss the most interesting things. Well, I'm waiting for you again on my blog. Good luck to you. Bye bye!
Sometimes users encounter such a problem that part of the keyboard on their laptop does not work.
In principle, it happens that the entire keyboard does not work at once, but then, most likely, it just needs to be replaced. But if only some of the buttons stop functioning, everything is somewhat more complicated.
We will consider everything that can be done in this case independently, without the involvement of specialists.
Simple ways to solve the problem
It is not always necessary to do something difficult in order to restore functionality. Often the problem is solved quite simply.
So from the very beginning, do this:
1.Try pressing the Fn and Num Lock keys. It is possible that pressing one of them blocked some buttons on the keyboard.
2. Hold Fn and press Num Lock, then release both buttons. In some cases, this simple method allows you to run full-time job keyboards.
3. Take a brush and go over all the buttons. It is quite possible that some dust has accumulated under one of the buttons. If possible, also take a vacuum cleaner. On the Internet you can find special vacuum cleaners for small keyboards.

4. Restart your computer. In some cases, there may be some minor bug in the system that prevents certain buttons from working.
In most cases, the problem will be minor and can be fixed with one of these steps. If nothing works, move on to the next step.
Fixing a software glitch
It is quite possible that the problem is the malfunction of some programs or services. To check this option, you need to do the following:
It's best to do this in a standard way:
- open the Start menu (Windows), then "Control Panel", find there "Device Manager";
Device Manager in Control Panel
- open the “Keyboards” item;
- Usually there is only one keyboard, right-click on it and select "Update drivers..."(if there are several keyboards, which is very unlikely, do the same with all of them);
- select an item « Automatic search…» ;
- wait until the drivers are found on the Internet, they will be installed automatically.
Updating drivers as standard the Windows way
You can also download and install DriverPack program Solution. It allows you to scan your entire computer for the latest available drivers.
If the keyboard has incorrect (roughly speaking, “broken”) or outdated drivers, you can easily replace them. The usage of this program is as follows:
- download the program (here is the link);
- install it and run it;
- An automatic scan will occur, after which just click on the “Update all” button.
Window DriverPack Solution
Read about other good similar utilities at.
If updating and scanning drivers does not help, try rolling back the system to a time when everything worked well.
To do this you need to do this:
- open the “Start” menu, then “All Programs”, “Accessories”;
- after that, go to the “Service” section and click on the item "System Restore";
System Restore item in the Start menu
- in the window that opens, click “Next”;
- then select the desired restore point, and here they are sorted by date and time (you need to choose the one that most accurately corresponds to the time when everything was fine);
Selecting a restore point for system rollback
- Click Next and then Finish.
In principle, it is possible to roll back the system in cases where safe mode The keyboard also doesn't work properly.
But in this case, the likelihood that it will help is very small.
Most likely, the problem is mechanical, not software, and it needs to be solved physical intervention into the computer device.
Fixing a physical glitch
In this case, you will have to look step by step to see what could have gone wrong.
To do this, run the following actions(it is very important to adhere to the exact order in which all actions will be listed below):
1. Turn off the laptop and remove the battery.
2. Take a flat-blade screwdriver and carefully remove all the latches on the plate that holds the keyboard in place. If you don’t see any latches on your laptop, you should pick up the instructions and read what it says about the design of the keyboard and how it is removed. In any case, some kind of fastening mechanisms must be present.
The process of opening the keyboard plate latches
The keyboard plate is attached to the laptop itself using a cable. You will see it immediately.
3. So, if there is obvious damage on it, the cable should simply be removed and replaced with a new one. To do this, take an old cable, go to the nearest electronics store and buy the same one.
Keyboard cable
4. If the cable is not damaged, it still needs to be removed. Under no circumstances should you take the cable by the conductors! You can only handle those plastic parts that attach it to the . For clarity, Figure 10 shows those parts that can be handled and those that cannot be handled. True, keyboards usually use slightly different cables.
5. There, under the keyboard plate, you can find the microcontroller. It's necessary dry and try to remove dust using a vacuum cleaner.
It is quite difficult to explain how to find this microcontroller. To put it simply, this is exactly the device to which the cable is attached. Just in case, when removing the keyboard, go through all the controllers you see. You won’t be able to do anything else on your own without special knowledge. Again, if you see obvious damage to the microcontroller, it is best to replace it.
Laptop with with the keyboard removed
6. If everything is fine with the cable, you will have to disconnect the keys and clean them. Usually the button can be removed in the standard way - pry it off with the same flat-head screwdriver. Start with the problem buttons. If you see damage underneath, replace the elements that secure the button to the laptop.
The process of removing buttons from the keyboard
7. Try using the keyboard again.
If the problem persists, remove all the buttons and remove the aluminum plate that is located under them. Usually it also has special fastenings that can be removed quite easily.
But underneath it is hidden a polyethylene board with traces drawn on it.
Inspect it for obvious damage - if there is any, there are two options: draw new paths or buy new board. In any case, go over the board with a vacuum cleaner.
To check the integrity of the tracks, use a tester.
Part of the keyboard on a laptop does not work: what to do and how to fix it - a detailed guide
5 (100%) 2 votesProbably each of us has encountered similar situation: you turned on the computer, trying to enter text on the keyboard or switch from one window to another, but the keys do not respond to pressing, and the device itself does not show any signs of life. What causes this behavior of the device? Why doesn't the keyboard on my computer or laptop work? And how to fix it? Let's consider what the reasons may be.
This is actually extremely awkward compared to others as it requires an excess of finger movement. Another standard is Dvorak. In addition, there are two other standards created for those who only need to enter one hand. Now check out some keyboards that might make you spend hours admiring the store window.
They usually have additional functions compared to conventional keyboards. You'll notice in the photo that there's also a mouse on the back of the touchpad-style peripheral. Anyone looking for practicality will want to have it. The keyboard below looks strange, but it makes the eyes of many gamers and graphics players sparkle because their keys are fully customizable not only in the function of the keys, but also in the position they occupy. You can literally put the keys wherever you want and assign them any function.
Mechanical damage
The simplest explanation is mechanical damage keyboards. Perhaps you recently spilled coffee or sweet tea on it, accidentally dropped it, pulled the wire, etc., and then conveniently forgot about it. In this case, all you have to do is disassemble the device and try to fix it yourself, or contact a service center. The second option is preferable, especially when it comes to a laptop keyboard. If you cannot bring the keyboard back to life, you will have to purchase a new input device.
Do your friends watch what you type and call you a “photographer”? It has both wired and wireless options and is available in Brazil. But it doesn't stop there, as the keys can be customized to display symbols for tools, commands, programs, or even images you've taken. Maybe in Portuguese we could have a keyboard that would better suit our needs and cause less pain in the hands of those who use the equipment for a long time long hours contract?
Why in Brazil no keyboard manufacturer offered before today change a standard that makes life easier for users? With such great success V software interfaces to make it easier for the user because the keyboard is stopped in time?
Lost contact
Sometimes keyboard problems are caused by the device not being properly connected to the computer. Check whether the plug fits tightly into the socket on the system unit and whether the fragile parts of the connector are bent. If necessary, carefully straighten them with tweezers and try connecting the keyboard again.
If you use a wireless keyboard, it's worth checking to see if its battery is dead. Very often the problem disappears without a trace as soon as the power source is replaced.
Feel free to give your answers and explain your theories using the system feedback. If your keyboard is no longer working, there are a few things you can check to resolve the issue. Depending on the situation, you can try one of the following options: first you must define two important factors in this troubleshooting solution.
Your keyboard no longer works
The problem occurred while typing, or you noticed it immediately after starting your computer. Besides extreme situation such as water spilled on the keyboard, the answer to this question is important in identifying the problem. If you notice that your keyboard has stopped working after downloading or, check your connection to your keyboard and make sure it is locked properly. You can reboot again.
No corresponding driver
Why does the keyboard on the computer not work if the contact is not broken and the device itself is not damaged?
Perhaps the system simply cannot find the driver for the device. In this case, you need to update your computer software.
You can do this manually by visiting the website of your keyboard manufacturer.
What keyboard are you using?
Disable desktop computer and check if it doesn't work. Also check the batteries, it may be time to change them. Wireless receivers have a signal scan button, press the button to transmit the signal and the light should start flashing. Once this happens, find the key on your keyboard to receive the signal sent by the receiver and flow with each other.
In some ways, these keyboards are more reliable because there are no drivers to install from the operating system. If it stops working while using the operating system, in most cases the problem is not caused by the keyboard. Check if your mouse is moving slowly? Do the same for each application that is not responding. You can also try this for any type of keyboard.
- Be patient and wait until the operating system finishes.
- On the Application tab, select all and click End Task.
- A confirmation window will appear asking you to stop it.
- Click "End Task" again and wait for it to complete.
Manual driver update
- go to the official website of the manufacturer;
- find the appropriate section, select your device model;
- download the archive and unpack it. Sometimes the driver has its own automatic installer, in which case you will just need to click “Run file”;
- if there is no automatic program, launch “Device Manager”;
- select “Update drivers”, in the dialog that opens, select manual search, enter the path to the folder in which you unpacked the archive;
- After installation, reboot the computer.
There is another way to update drivers. It is often recommended on thematic forums when a participant does not know why the keyboard does not work on a Windows 7 computer or other OS. You won't have to look for manufacturers' websites, but you will need to install additional programs to update drivers. For example, Driver Genius Professional or Driver Checker. These utilities are paid, but if you wish, you can find a replacement for them among free software (DriverMax Free, etc.).
If your keyboard no longer works, but you have a good second known keyboard with the same connection type, replace correct keyboard on the wrong one and see if it works. You can also try to connect wrong keyboard to another computer and determine if the keyboard is broken.
Troubleshooting Wireless Keyboards
If some keys on your keyboard work but not all, do next steps that suit your situation. The eject button mechanism starts after a short delay to avoid accidental use. Press and hold until the eject icon appears on the screen.Viruses attacked
Sometimes input devices are blocked by malware. If you don’t know why the keyboard on a laptop or computer, and along with it, the touchpad and mouse, then the problem is most likely viral infection systems. What to do in this case?
and how can I fix it? Forgot your computer password? Don't worry - in our article you will find information on how to restore it.
Check your system with an antivirus as soon as possible. If the antivirus did not detect a potential threat or is simply disabled, use additional utilities. The Dr.Web CureIt! program is very effective in such situations. You can download this anti-virus utility on the official website of the Dr.Web laboratory. The program is free for treating home computers. The most important advantage of the utility is its high reliability: the program will work even if a virus tries to turn off the computer during the scanning process and block it.
Common problems with keyboard customization software
You may have configured a setting that changes the behavior of the keys. If the "Speak selected text when you press a key" option is activated, deactivate it or click "Change" to select a different key. If it is activated, you must hold the keys longer than usual for the action. In the Accessibility area, click Mouse and Trackpad. Make sure "Enable Mouse Keys" is turned off. If it is activated, pressing digital buttons moves the pointer, not the number. In the Keyboard panel, select Input Methods. Make sure it is selected correct type keyboards.
Problems with keyboard functionality such as calculator, sound or brightness settings
- In the Accessibility area, click Speech on the Left.
- Make sure the "Enable slow keys" option is disabled.
You can also recommend the development of Kaspersky studio, AVZ. Like Dr.Web CureIt!, the program is free. Updated regularly. It has several settings options, which allows you to most effectively identify not only viruses and spyware, but also possible system vulnerabilities. Quickly eliminates “computer infection” and gives many useful recommendations.
Identify your keyboard in this list or search in the search bar. Once you have identified your keyboard, tap or click on it to go to the download page. During installation, you may need to restart your computer one or more times. If you log in as a member of a guest group during the installation process, an error may occur.
Some computer manufacturers come with pre-installed keyboard customization software tailored to the keyboard that came with your computer.
- Unplug your keyboard, then plug it back in.
- If you are using a wireless keyboard, check your wireless connection.
The keyboard is simply not connected in the BIOS
Finally, last reason“lifelessness” of the device - lack of connection in the BIOS. This case is typical for netbooks and laptops, i.e. devices with a built-in keyboard. How to fix the situation?
Very simple. Turn off the computer, then turn it on again. Before the operating system starts loading, we load the BIOS. Usually to do this you need to press Delete button, But there may be other options. Sometimes the BIOS is activated by pressing the F2 or F8 keys (depending on the computer manufacturer). The hint at the bottom of the screen (if there is one) can help you determine which button to press.
Try the following tips. Some key commands require the installation of a specific program, such as an email program, web browser, media player, sharing program instant messages or graphics editing program. Keys quick access may not work as expected if you press the modifier key at the same time. If correct program is not installed, you can still use the key by reassigning it.
If your computer has two connected wireless receiver, and you press one key on your wireless keyboard, double characters may appear on the screen. Some keys are designed to repeat when pressed and held. The following buttons can be repeated: previous, next, previous track, next track, volume, volume, zoom, zoom.
Then we find a tab in the BIOS that lists all input/output devices. Select the item called “USB Controller” and set the mode to “Enabled”. Go to the “USB Keyboard Setup” item and repeat the operation, setting the mode to “Enabled”. Then we confirm saving the changes and exit the BIOS. Reboot and test the keyboard.
Where are the standard function keys?
These keys are located in top row keyboards. On some keyboard models they are tactile.

If you hold down the Gadgets key, all open windows will be transparent, allowing you to see the gadgets on your desktop. In other versions or themes, when you press or hold the Gadgets button, you view the desktop. "Print" button. screen copies the screen image to the clipboard. . On some keyboards, the My Favorites keys are secondary.Sometimes the BIOS does not support USB keyboards. In this case, it is better to entrust computer setup to professionals from service center because you need to reinstall the BIOS. Doing this on your own is quite difficult.
There can be only two exact reasons for this malfunction:
The standby key puts the computer into power management mode only if the computer supports power management and power management is enabled. If it is not activated, this button does not work. It cannot be reassigned. You can resume work by doing one of the following:
- Press the wait key.
- Press the standard key on your keyboard.
- Move the mouse.
- Quickly press the power button on your computer.
- Then click it again.
- Restart your computer and press the Home key.
- hardware (in the case when the device itself or the port to which it was connected failed);
- software (failure to load the required driver).
If the keyboard fails, then there are only 2 ways: replace it with a working one or repair it.
- To begin with, of course, you can try restarting your computer. It is possible that after a reboot it will work again.
- If rebooting doesn't help, you can use the keyboard with the mouse (it should function fine).

➤ This is cool: You still don’t know - it’s simple.
Probably, each of us has encountered a similar situation: you turned on the computer, are trying to enter text on the keyboard or switch from one window to another, but the keys do not respond to pressing...
The keyboard is the main way to enter information into a computer. Therefore, without working keyboard It is almost impossible to use the computer. Now we will look at the main reasons why the keyboard on your computer may not work and tell you how to fix it.
Reason #1: Connection problems.
If the keyboard does not work on your computer, then the first thing you need to check is its connection. You could have snagged a wire and partially or completely disconnected it from the computer. To check this option, disconnect the keyboard, reconnect it and check how it works.
Most modern keyboards connect using , but if you have an inexpensive or older keyboard, it can connect using PS/2. In this case, make sure that the keyboard is connected to the purple PS/2 connector and that the connector on the keyboard side is not damaged. The fact is that this connector consists of several rather thin contacts and if they are bent, the keyboard will not work.
You also need to inspect the wire itself, which goes from the keyboard to the computer. It could have been damaged by pets or it could have simply been worn out.
Reason #2: Batteries are dead.
If it doesn't work for you wireless keyboard, then you definitely need to check its batteries. To do this, simply replace the batteries with new ones and check the operation of the keyboard.
You also need to check whether it is connected to USB connector the receiver that should receive the signal from the keyboard.
Reason No. 3. Num Lock is turned off.
If the main part of the keyboard works, but there is no button on the additional numeric keypad, then you need to enable Num Lock. To do this, simply press the Num Lock key, which is located above the numeric keypad, and then check how the numeric keys work.
After pressing Num Lock, the light above the numeric keypad should light up, indicating that Num Lock is enabled. Wherein numeric keypad must earn.
Reason No. 4. Problems with drivers.
In some cases, some USB ports may not work without installation for the motherboard. Therefore, if you connect the keyboard and it does not work, then just try plugging the cable into another USB connector and check again. If the keyboard works with a different USB connector, then most likely you do not have the drivers for the motherboard installed. Go to the board manufacturer's website and download required driver and install it.
In addition, the keyboard itself may also require drivers. If you have simple keyboard, then it should work without drivers. But, modern keyboards Gamers often require driver installation. In this case, you need to go to the keyboard manufacturer’s website and download suitable driver and install it on your computer.
Reason No. 5. The keyboard is faulty.
Keyboard failure is enough a rare event. Usually, on old keyboards, individual keys stop working, which is why they are replaced before they completely break.
However, this option cannot be ruled out. If you have checked all the above and the keyboard still does not work, then you need to test it with another computer. Perhaps it is simply faulty.
If the computer does not work, we begin to have problems, because our own PC has replaced a lot of functions for us today. First, you should not panic, especially for beginners; a computer is a piece of equipment that tends to break down. Try to determine what exactly is not functioning.
5 reasons why the keyboard on your computer does not work
If all devices have responded, but the keyboard is silent and does not respond to our actions, then it is worth eliminating the most popular 5 particular reasons:
- The cord was incorrectly connected to PS/2 or USB.
- Perhaps the port of one or another keyboard connector has burned out.
- The keyboard has become unusable.
- If we have a wireless option, we check the presence of the necessary drivers and utilities, as well as whether the battery is working.
- The presence of a virus code that has blocked the keyboard.
What to do
We eliminate the above problems.
Check the correct connection to the system unit.
Check the integrity of the cable for kinks and breaks.
You can verify that the keyboard is working properly using another PC.
Sometimes, due to inexperience or carelessness, it happens to bend the antennae PS/2 connectors , they must be aligned with tweezers or a knife. When at least one breaks, it is necessary to change the cable input or the entire input device. Try to remember: purple the color indicates the keyboard cord, and green - mice.
PS/2 connectors.
Please remember that the battery as well as battery devices, tends to discharge, then it is necessary to replace the power source or fully charge it.
In addition to the problems described above, which are solved quickly and are called “typical”, there are also more significant ones.
Buttons are pressed but do not respond
There is a classic version of the keyboard and its multimedia version. You can make them work by configuring necessary drivers. These programs may change or fly off"When setting up the OS. Such keyboards are rare; most manufacturers install drivers without our participation, in automatic mode.
It happens that the user simultaneously presses several buttons or a combination of them. In this case they " sink"and none of them responds. Make sure the keys are not obstructed foreign objects. Often crumbs get in, and the elastic band inside slips off. It is recommended to wipe the rubber band with a dry cloth, and the keyboard can be damp. When everything has been tried and the issue is not resolved, it’s time to think about buying a new peripheral device.
There is a situation where the keyboard is not fully functional; it is not possible to type the numbers on the right. To do this, check the keystroke "Num Lock".
The computer did not detect the keyboard.
In this case, you need to restart the PC, there is no result - go to the control panel. Calling context menu icon" System". Go to “Properties” and click “Hardware”. Finding the point "Device Manager", select a keyboard sign from the list and delete it. You should then close this window. Next, select the menu"Equipment installation"and install the drivers for the keyboard.
These steps will help you get rid of software problems with an input device.
Checking the connection in the BIOS settings
When such methods do not produce results, you need to turn off the PC and turn it on again. Before loading the OS launch BIOS. Buttons are responsible for this Del, F2 or F10 depending on the configuration (you will find out more precisely when loading at the bottom of the screen)
