Why the keyboard does not work when Windows startup. After Windows downloads, the keyboard does not work the Windows Remissal Loader does not work
In the configuration of the computer. Practically, all data and actions are entered due to the keyboard, and any mouse movement there is a key combination. Therefore, the keyboard failure after loading the system threatens at least the difficulties of a set of text information ...
Windows is loaded, and the keyboard does not respond to your commands. The reasons are only two, hardware and software. Moreover, the first is much more common, and is solved by a simple replacement of faulty equipment.
Checking keyboard
To check the hardware, that is, the keyboard itself, you will only need an obvious input device. First, make a visual inspection of computer connections (USB or PS / 2), as well as cable and connector of your keyboard.
In the case, with a USB connection suffers from the connector, where contacts can move, and bring the computer to the closure. With the PS / 2 connector, on the contrary, the defect occurs in the plug in which the contact legs are bent or bow. If the inspection showed that there are no deviations, we try to connect the prepared keyboard.
Be sure to completely turn off the computer, and then disconnect the keyboard to replace. It is better if the second keyboard will be the same type of connection, it will help to localize the problem. If the device similarly behaves after booting Windows, then it follows, seek the reason in the software.
Check Driver
The software is meant the required set of drivers, which must determine your equipment. If the driver is installed incorrectly or has incompatibility with the operating system, you should reinstall the ILI keypad to display the latest version of the driver.
On Windows, we get to the Device Manager, where we find the keyboard (depending on the type of connection). Please click on the right mouse button and choose from the context "Delete". Further, enough, restart the computer so that the system is found and installed equipment (or use the new equipment connection wizard).
In the case when you want to update the driver, refer to the Internet. On the official website of the manufacturer we find a section of downloads where we find the name of your device model. Download the installation file to your operating system, and then set the double click.
Non-standard reasons
If all of the above did not help in your situation, then you should check the BIOS settings. One partitions is responsible for the operation of input devices. Usually, this option is possible during manual intervention, and if it was not, then you can limit your actions.
A variant and with viral infection is possible. In this case, both input devices, and a keyboard, and a mouse ()) suffer. Usually, the action of such "pests" exclude work in the usual mode when the "safe mode" remains at your disposal. Using this type of Windows boot launch
Users usually notice when reinstalling the operating system when you want to set the priority of the download, or in case of changing the additional settings of the primary I / O system. What is the reason for such a phenomenon and how to deal with it, now will be considered. Immediately I want to note that not everything is so bad. There are several basic methods to solve the problem of several minutes. Consider them.
The keyboard does not work in the BIOS: Causes
Many users pay attention to the fact that in a normal functioning operating system such situations are observed, but very infrequently. Mostly it concerns the BIOS.
Among the main reasons for the appearance of such a situation, most professionals identify the following:
- physical damage to plugs and wires;
- incorrect connection;
- old computer without supporting the connected device;
- incorrect setting of BIOS parameters.
The problems associated with physical defects or damage are not now being considered. In extreme cases, if the keyboard does not work in the bios, check the performance of the device of an external type of PS / 2 standard or USB standard, connecting it to another computer terminal. If everything is in order on it, the reason should be sought in your system unit (more precisely, in the jacks and ports to which the connection is made).
What to do in the first place?
As for troubleshooting, first of all, you should check the correct connection.
In the case of USB keypads, it is incorrectly connected via the corresponding port is incorrectly enough (although sometimes it can make that the keyboard refers to the USB 3.0 standard, and is connected to the USB 2.0 port).
But most often the appearance of such a situation is more characteristic of the keyboards of the old PS / 2 standard. The connection is needed, taking into account the fact that the color of the keyboard plug and the corresponding socket must match (they have purple). However, in this case it is quite difficult to make a mistake.
How to go to BIOS (keyboard does not work)?
When attempting the primary system, it may very often cause a failure, the question of accessing them arises, because to call a bios or move to the configuration sections without a keyboard, in most cases it is not necessary.
But there is a solution. For example, we have a situation where the keyboard does not work in the BIOS on the laptop. Log in to the system settings can be made in several methods. Some laptop models are originally equipped with special buttons on the panel with which the bios parameters section are called. In particular, this concerns Lenovo products, Sony Vaio (Assist button), etc.
The second access option in the case when the keyboard does not work in the BIOS, the external analog is connected via the USB port. But here you need to remember that the external keyboard is preferably connected without meals, and only then turn on the device for loading.
Reset
Previous decisions can be called universal in some sense, however, they may not give the desired result. This can be observed when the USB keyboard does not work in the BIOS. Such a problem is only associated with the fact that in the system itself there was some kind of failure.
In this case, you should make a complete reset of the set parameters. Anyone, even the old stationary computer allows you to get to the motherboard on which the CMOS battery is installed. It is necessary to just pull out of the socket for a few minutes, insert back and try to enter the settings by turning on the load terminal.
Installing correct parameters
But here there are your pitfalls. In the case of USB keyboards, the problem may consist of deactivated support for devices in the most primary system.
In this case, you will have to connect the PS / 2 keyboard or, if there is such an opportunity, enter the BIOS on a laptop through the press of a special button, after which you find the parameters like Legacy USB Support or USB Keyboard Support and look at the set value. If the reason is really in this, it will be installed on disabled. It needs to be changed to Enabled and save changes at exit (F10, Y). Next will follow the reboot. Perhaps it is in this way that it will be possible to eliminate the problem.
What could be more?
As evidenced by feedback, sometimes the failure of the keyboard can be associated with damage to the RAM schedule, disorders in the operation of the power supply, shorting some contacts directly on the motherboard, port malfunction, etc. .. Here, without complete diagnostics of the entire system, it is not necessary.
Finally, there is also a problem with the BIOS system itself, which consists in violating its work or obsolescence. In this case, you will have to make a complete flashing, but this is unsafe, and without special knowledge, the ordinary user can apply an irreparable damage to a computer, as a result of which the PC will stop working at all.
Instead of the result
Based on all the above, it can be concluded that, regardless of the current situation, not counting physical damage or defects, the problem of the inoperability of the keyboard and access to the primary system is sufficient simply.
But the causes of such a phenomenon can be a lot. And they are not always connected exclusively with physical defects. In most cases, for the same USB devices, it is enough to simply enable support or make a common reset. It helps in 99 cases out of 100.
Finally, if we talk about a global problem, when the keyboard does not work at all, it is possible to determine it 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 have to either check the correctness of the connection, or use the methods proposed above up to the replacement of the device failed new.
Sometimes it happens that PC users encounter such a situation: when the computer is turned on, the keyboard does not function. It seems that everything is connected, but the buttons do not react to pressing. When restarting the device, the keyboard works, but only in the BIOS. As soon as the download begins, it turns off again and does not apply signs of life. In addition, a warning may appear on the screen asking you to choose a safe mode, and the elementary press of the F8 button does not give any results.
The first thing that comes to mind is to replace the keyboard. However, you should not hurry. If it is not in the item itself, then the new boot will react just, or rather - in no way. Therefore, check the other potential reasons first.
The case may not be at all in the keyboard, but in the cunning Windows setup. As a rule, most users today use USB devices, others have not been released. In this case, the problem is associated with disconnecting to the support of your keyboard when loading the system.
What went wrong and how to fix the situation?
Such troubles arise precisely because of the OS failure. When you turn on the computer, the system stops responding to a device that used to be automatically connected, and as a result, the keyboard does not work. In other words, the operating system simply "does not see" the device.
But do not despair. The recipe for the correction of the situation is much easier than it may seem at first glance. It is necessary to make sure that the keyboard is properly connected. Otherwise, everything that will be discussed on, will not work. In this case, still have to look for a replacement. To begin with, try to reconnect the keyboard to another port. If it does not help, go further.
The next step is to enter the BIOS. To do this, clamp the Del, F1 or F2 key (on different devices, the input in the menu is performed using different buttons, most often it is DEL). Hold the desired key within a few seconds.
On the blue screen, you must find the menu item associated with our keyboard. It is usually called a USB Keyboard Support, and in some models it can be called Legacy USB Support. In the case under consideration, opposite the item will stand a mark that the option is disabled. To activate the keyboard into the BIOS, it is sufficient to switch to Enabled mode. Do not forget to save the settings. To do this, press the F10 key and confirm the changes made. Now restart the computer and check the result. Now the keyboard works in normal mode.
Instruction
The main reasons for such a malfunction are in a hardware failure or software error. Check the hardware version is very simple - check the plug on your keyboard and connector connector. If visually everything is in order, replace the keyboard on the serviceable and overload the computer. In case of further inability to use this device, check the version of the software malfunction.
To begin with, try to restart the car. Perhaps the operating system localizes and eliminates the program failure. Try reinstalling the keyboard. To do this, in the "System Properties" window of the "Control Panel" window, find the "Equipment" tab. Click the Device Manager button. In the Device Manager window, select the "Keyboard" item and delete it, close the Device Manager. Then log in the Installation of the Equipment and launch the Installation Wizard. Click the Next button and wait until the installation program detects the keyboard. On the detection and operation of the OS keyboard, communicate the NUM LOCK light indicator. If the program displays the message about the completion of the installation of new devices and prompts you to restart, press the "No" button, because the keyboard is already functioning. Click also the "Finish" button in the "Equipment Installation Wizard" window and exit the "System Properties" menu.
One of the fault options may be the fact that the operating system does not detect the desired driver. To reinstall the driver, go to the manufacturer's website of your keyboard, select the desired model, download the archive and unpack it. As a rule, such drivers are equipped with their installation program, and then you should simply start the file. If there is no such is missing, you will have to run the "Device Manager", select the "Update Driver" command and specify the path to the directory in the manual search mode in which the unpacked driver is located. The computer after installation should be restarted.
Often, non-working keyboard is a consequence of a viral program that has settled in your car. A characteristic feature of this is the failure of the mouse, as well as touchpad. Check the system using the antivirus program. It is better not to rely on free utilities promising instant success and cure of your computer. Use the proven and famous antiviruses. The chances of success with such provision is much higher.
A very real cause of the keyboard failure may also be the lack of a BIOS connection. This failure is especially often marked on machines with a built-in keyboard. Fix the situation is quite simple. In the course of the computer download, turn on the BIOS. Find a tab with a list of input and output devices. Select USB Controller and enable Enabled. Enable the same mode for the USB keyboard setup item. Exit BIOS with confirmation of the saving of new parameters. In the event that nothing of the listed helped you, contact the service center.
Hello everyone, dear friends. Most recently, I had a strange at work, as it seemed to me, the situation. Just stopped functioning the keyboard. Rather, not quite stopped. As it turned out, the keyboard only works in the BIOS, and with further download it simply stops responding to any pressing.
And here also an unpleasant situation happened, or rather failure. After rebooting, it was necessary to choose the download mode, but I could not do anything, because I didn't react any of the keys. The first thing I thought it was to blame the keyboard, after which I replaced it to a new one, but it turned out, but after i Put another device, the situation has not changed.
In general, I will not tomorrow. Most likely you used a USB keyboard, since with PS / 2 such problems have anyone arose. The fact is that the USB keyboard support is disabled in your BIOS when booting Windows.
"How so? After all, everything worked before, "you say. Yes, indeed, you could do everything, and you could not notice anything, since when loading the operating system, it automatically activates this support. But as soon as the failure occurs, and you need to make any actions during the download screen, then alas, you will not be able to do anything.
How then do it? Immediately I want to say that the first thing you need to check the simplest thing that can come to your head, because sometimes the problem can really be somewhere on the surface. Therefore, at first, check if the keyboard cable is connected to the computer, try to rearrange it in another USB port, well, and if there is an opportunity, connect another keyboard.
If nothing of this helped, then most likely the case in the setting. You need to enter Bios.Namely at the very beginning of downloading your computer to press the function key that is responsible for the entrance. Most often it is key Del.but in different cases it may be F1., I. F2..
As a result, when you get into the BIOS itself, you, depending on the version, you will need to find the item associated with the support of the USB keyboard. It may be called "USB Keyboard Support" or "Legacy USB Support". If you see that in front of these items it is the "disabled" mode, then the support is disabled and you need to activate the "Enabled" mode.
After that, we save all the settings, reboot and voila.
As a rule, this setting is the solution to this problem. Although I heard that someone did this decision helped, and he decided to try to look for a problem in the components. It turned out that one level of RAM was not entirely working (from his words) and when he pulled it out, the keyboard earned in normal mode. I do not know how it is interconnected, but in the event that you can try this method.
