Why the keyboard works only in the bios, and when loading it turns off?
BIOS is an assembly of micropolograms that regulate the operation of all devices and loading the operating system. In fact, this is the most important component of any processor. BIOS is located in the motherboard, since the motherboard is responsible for managing all computer devices.
In certain situations, there is a need to go to BIOS. For this, there are many ways both using input devices (keyboard) and without it.
We will tell you how to enter BIOS if the keyboard does not work.

That’s why you need to use BIOS where the mouse is supported)
I read everything and checked it, did not work on the wines hp Pak 3. But there is a suspicion that where the claw is disabled, since when the PC is running, turning off the connector for a couple of minutes and turning it on, the indicators instantly light up on the clave, that is, the testing has passed, and the keyboard does not work and it does not work in the equipment. Clava is working, one thing remains. The reinstall of the Windows, the update of the drivers helped once before the reboot, there is no way to go in BIOS, the battery did not work.
Mom Intel DZ77BH-55K buggy from Novya. But still worked. Now the network card driver is constantly flying, you need to delete it, then re.Set. Put different drivers, but nothing changes. Now, when trying to go to BIOS, the post displays E7, and does not respond to the mouse nor to the keyboard, and the menu is sometimes displayed on the monitor, but more often the screen is empty. I tried different keyboards and USB and PS. PS: I must say that I saw a lot of Intel boards and many people complained about many people. What BIOS I don’t know, since not to get. The system is loaded, it works, except for the problem with the network card.
Everything works in the system, but at the entrance to the BIOS, neither Klava nor the mouse reacts. What is the reason?
Forced cleaning with the extraction of the battery
On devices that do not have a special button for quick tolerance to the BIOS, it is necessary to compare forced cleaning. It is carried out by extracting the battery.
Forced cleaning algorithm
- We de.Energize the computer. To ensure complete discharge of capacitors, you need to clamp the power button several times.
- After that, we find a battery in the block (or inside the laptop body), which looks like a coin with its appearance.
- Gently pull it out.
- After five seconds, insert the battery into place in the same side.
After these actions, the BIOS settings will be reset and the keyboard will work again.
Methods of solving the problem
If the keyboard you have chosen to enter the BIOS is used for the first time, then, first of all, having encountered a situation where the keyboard input does not work, it is necessary to check the performance of the device by connecting it to another computer.
If the keyboard performance is not in doubt, then you can try to connect another type of keyboard to the computer. That is, if you use a keyboard connected to the USB connector, you can take the keyboard connected to the PS/2 connector. Or vice versa, if the computer does not upload BIOS using the PS/2 keyboard, then you can try to connect the USB keyboard. In most cases, this option helps to eliminate the problem.
Also, to exclude the possibility of conflict between the keyboard and other USB devices, you can try to disable all the other devices connected to the USB connectors. Theoretically, there may be a conflict between PS/2-mesh and PS/2-keyboard, so it also makes sense to disable the mouse in this case.
However, if all the above methods do not help turn on the keyboard input, then most likely you will have to drop the BIOS settings to the default installations. This is done by extracting a battery on a system board from your nest, or installing a special jamper. Information on how to carry out this operation, we wrote in a separate article.
After you manage to include the keyboard input and you will enter the BIOS, do not forget to check the BIOS parameters associated with the connection of external devices so that this situation would not be repeated in the future. For example, in the bios there are options similar to USB Keyboard Function options that block the possibility of connecting USB input equipment. If you have a similar option, then it will need to turn it on.
What to do if the keyboard does not work in BIOS
First, check the correct connection. To do this is quite simple if you clearly follow all the recommendations provided.
Checking the correct connection
In order to make sure that everything was done correctly, check the plugs of your keyboard.
If it is a USB model, then the probability of error is extremely small. The only thing that may be wrong is the device is connected to the nest of the wrong format, for example, the USB 3 standard.0 often confuse with 2.0.
Devices connected using another port must be inserted precisely into those nests that correspond to color. If everything is true, then we move on to the next step.
How to enter BIOS
What to do if you enter the BIOS is not possible due to the inoperability of the keyboard ?
Do not panic-you can always connect another device via a USB port. If you use a laptop, then look for special buttons on the control panel, with which you can not only go to BIOS, but also navigate, change or save the settings.
If even the keyboard connected via another port does not work, then you have to reset the settings.
Most likely, a failure occurred in the system. To eliminate the problem, it is necessary to remove the CMOS battery from the nest. Access to it is available on any computer model, which allows you to reset the settings.
After that, insert the part back and restart the system. Most likely, at this stage, the keyboard will work.
Installing the right parameters
In some cases, the parameter is disconnected in BIOS, which is responsible for supporting USB devices. Then you just need to set the right settings. But for this you will need to connect another device, the plug of which is inserted into the PS/2 port.
Then find the desired parameter and set the Enabled indicator opposite it, which means “connected”. In different models of computers, the name of the parameter may vary, so it is best to find the instructions for your device on the Internet in advance.
Finding out the cause of the malfunction
There are several main options, thanks to which it is possible to accurately identify the cause of the malfunction:
- The first and, of course, the main thing to start is to check the connection, that is, its correctness. In this case, it is worth noting that the standard connector is almost impossible to connect, which cannot be said regarding PS/2. In the latter case, proper compliance with the color is required.
- The device may not work because the wires are damaged. This question is especially relevant when there are any animals in the house.
- You can try to correct the situation by turning it off and connecting the set of keys back, but this should be done only at a time when the computer does not work, that is, it is turned off.
- To make sure that the key set is about the serviceability of the set, it is best to connect to another PC or laptop.
- Check ps/2 connector.
One of the reasons that the keyboard does not work can be an inaccurate connection of the PS/2 connector, in particular, bent legs. For simplicity, convenience and avoiding incorrect connection, the connector has a certain color. Purple.
USB-keyboard does not work: possible reasons and ways to solve the problem
Suddenly, any USB-keyboard can work-at least a regular budget, even with an advanced design, backlight and a bunch of additional buttons. USB-keyboard is not much, but still more vulnerable than the keyboards connected via PS/2 port.
The list of possible causes of problems with the PS/2 keyboard: as a rule, problems arise either with the keyboard itself, or with the wire, or with the motherboard connector. The circle of possible reasons for the problems with USB-keyboarding is slightly wider, respectively, due to the USB integration itself.
For the possible causes of the non-working USB keyboard and ways of leaving the situation we will understand below.

Pulled out wire
If the USB keyviling has successfully worked, and then at one certain moment stopped responding to the input, it is worth checking to check whether the wire is pulled out of the USB port on the computer. Even if the wire is in place, you can temporarily remove it from a USB port and insert it again in a couple of seconds.
Another USB port
If the previous method has not given successful results, it is necessary to reconnect the keyboard to another USB port. This will either reveal that one of the USB ports does not work on the computer, or will exclude one possible reason for the malfunction.
After a malfunction in the work of the motherboard as a result of a voltage surge, one or more USB ports may stop working, while others will remain workers.
If the keyboard has not earned with any of the USB ports, it is necessary to check the performance of the USB ports themselves, connecting any other device to them-a flash drive, a mobile device, a printer, etc.P. If all USB ports turn out on the computer, the problem will then need to be solved with them.
Keyboard connected to USB 3.0 (port with blue output), may not work in the process of installing Windows, until the driver on the motherboard is installed. In this case, the keyboard must be reconnected to USB 2.0 (port with white release).
Reinstalling the driver
If the reconnecting to another USB port has no results, you need to check if the keyboard is working in the BIOS environment. The fact of a successful entrance to BIOS and navigation keys to its sections will mean that the problem arose at the level of Windows OS. In this case, you can try to reinstall the keyboard drivers. You can do this in the Windows Device Manager. You can get into it in the Windows 7 system by calling the “Start” menu and selecting the “control panel”.
Next, you need to set the “Small Bades” value in the “View” column, and then start the device manager.
In Windows 8 systems.1 and 10 The path is shorter: Direct Direct Device Device is available in the context menu on the “Start” button.
Directly in the window of the devices dispatcher, we open the “keyboard” section, at the “Keyboard HID” point we call the context menu and delete the driver.
After rebooting, the keyboard driver will be installed automatically.
For individual models of USB keyboard, manufacturers can provide their drivers supplied along with such keyboards. This moment must be clarified, and if so, then, the driver needs to be installed manually by downloading it on the manufacturer’s website or finding the installation disk in the keyboard delivery kit.
Turning on the USB controller of keyboard support in BIOS
A malfunction of the motherboard (as a result of the same voltage jump) can cause disconnection of the USB controller of keyboard support in the BIOS settings. Not often, however, it happens that the USB controller support for the keyboard at the BIOS level is originally disabled.
This nuance will make itself felt only when the need for a computer in pre.Loading mode arises. Until this moment, the Windows system will use the USB keyboard with its own means.
Of course, in such cases, PS/2 keyboard cannot be dispensed with, and if one is not stored anywhere just in case, it will be necessary to borrow it from someone for a while. Alternative. The use of the USB adapter. PS/2.
What needs to be done when entering BIOS? In the BIOS settings, you need to find the USB controller of keyboard support parameter. These are usually the inscriptions “Keyboard Support” or “Legasy USB Support”. BIOS UEFI may be just “USB Support”. Having found, you need to check that the value opposite is not “Disabled” (off), but “Enabled” (inclusive). The value of “Enabled” should also be in the parameter “USB Controller”. For example, in Ami BIOS version 17.9 USB controls are configured in the Integrated Peripherals section.
And finally, the simplest test for checking the performance of the USB-keyboard itself is to connect it to another computer device.
Why does the computer not see the keyboard: what to do
When a computer is turned on, a system can occur. When you press the keys, the keyboard does not respond. It’s all about the software malfunction, there was an error when loading drivers. You can fix this problem on your own. Reboot the computer and check if the device has earned.
You can fix the problem using the device manager:
- We open the desktop. Press the Start button.
- Select the device manager.
- We are looking for a keyboard line.
- We delete if the device works incorrectly.
- We update the configuration.
The computer will eliminate errors and reinstall the keyboard correctly. On the manufacturer’s website it is better to download the last drivers for your device. The keyboard will work more correctly, which will continue to protect it from breakdowns.
Check if the wire is deformed and the connector itself. If you use a wireless device, look, maybe it just got out. Do cleaning, perhaps the whole thing is that she just clogged with crumbs or water. If the indicators do not burn, and the buttons do not work, the reason is in the mechanical breakdown. It will have to be replaced with a new one, even such damage can not always be eliminated even a master.
Mouse and Keyboard shut off when Windows Starts but works in BIOS [SOLVED]
Why does the computer not see the USB keyboard
First of all, we check the correctness of the connection. We inspect the cord for the presence of breaks and damage. If you use a wireless product, the first thing we check the USB transmitter and battery. Try to switch the transmitter to another connector if the product is not filled, then the breakdown is precisely in their malfunction.
During a safe pumping or reinstalling mode, a failure may occur. If you see that the indicators are not burning, when clicking Capslock, the keyboard does not respond, check the connection settings in BIOS. We follow the instructions:
- We start rebooting the computer.
- At this time, press the F2 or DEL key. BIOS should load.
- Change the Disabled value to Enabled in the Legacy usb section.
- We save the settings, re.Load.
After the actions performed, the device must earn.
Why does the new keyboard not work on the computer
First of all, we reboot the computer. If nothing has changed, download the drivers and try again. You can call technical support or warranty center.
Try connecting the keyboard to another computer. She does not work there. It means that you came across a defective. Under the warranty, you must replace it with a new.
Perhaps the problem is in the connector of the computer itself, then you have to call the master. When moving from PS/2 to a USB, a computer may not see it. We go to BIOS and change the values. In wireless device, check the batteries. Turn off the computer, disconnect the keyboard and insert it back.
Why the keyboard does not work on the Windows 10 computer
A failure is not uncommon. When reinstalling Windoows to version 10, there are often problems using the keyboard, it just refuses to work. Be sure to check your computer for viruses. If you have an antivirus, do not relax, it is noticed that it is it that blocks the work of the keyboard.
In case of violation of the software work, go to the settings section. Select the keyboard subsection, correct errors in the settings. In most cases, it is enough to disable the function of input filtration. Windows 10 knows how to eliminate problems. In the parameters, we are looking for a means of eliminating problems and launch it. Then you will only need to follow the instructions.
There are many violations and ways to eliminate problems on Windows 10, but you can cope with them yourself. When checking in BIOS, you can find that the computer shows the serviceability of the keyboard. When working in a notebook or applications from the store, we see the opposite effect.
The keyboard does not work. What to do in this case? The reason is that the CTFMON process is not launched.EXE. You should not have problems with its installation. If you decide to install Windows 10 on your computer and use a USB mouse, then as an option you can try to recover the product to another port and it will start working.
The method is not 100 %, but you can try! One of the most frequent cases why the keyboard is working or not lies in the error when operating quick launch. In the settings, you can find the point of settings of power buttons. We cancel the quick start and do not forget to save the changes.
Important! When rebooting the computer using the start button, the problems disappear. Canceling a quick start will be much easier than restart your computer every time.
If nothing helped you at all, from the above, you will have to download the driver for the mouse from Windows 8. Search for updates again. First you need to delete all the drivers.
Instead of the result
Based on all of the foregoing, we can conclude that, regardless of the situation, not counting physical damage or defects, the problem of the keyboard inoperability and access to the primary system is solved quite simply.
But there can be a lot of reasons for this phenomenon. And they are not always associated exclusively with physical defects. In most cases, for the same USB devices, it is enough just to enable support or make a general discharge. This helps in 99 cases out of 100.
Finally, if we talk about the problem of global nature, when the keyboard does not work at all, it can be determined immediately on the welcome screen when the computer terminal is turned on (it will be reported that the keyboard is missing). In this case, you will either have to check the correctness of the connection, or use the methods proposed above until replacing the failed device with a new.
