The keyboard on the laptop only works in the BIOS. What to do if the keyboard does not work in the BIOS. The keyboard on a laptop may not work due to physical damage

If you read these lines, it means that your keyboard stopped functioning normally: individual buttons do not work or it does not work at all.

The reasons why the keyboard does not work on a laptop several:

• Software - due to damage to drivers, conflicting software, incorrect settings.
• Hardware - due to mechanical damage. Due to spilled fluid, dust and other garbage.

We analyze in detail every reason and eliminate problems.

Software Reason: Drivers Flowed

In the right corner of the Yandex search string there is a small icon of the on-screen keyboard, with which you can write any requests.

If it is not possible to restore the keyboard built into the laptop, you can connect an external one.

For a stationary computer it will be easily suitable for a laptop.

The main thing is to choose a keyboard with a USB connector, as you can hardly find the PS port on laptops.

Hardware Cause: Spilled liquids, dust

The cause of the keyboard malfunction is often different liquids spilled on a laptop.

Dust of crumbs, villi in the house where there are animals, all this accumulates under the keys and with time it makes it difficult to work.

If you get any liquids on the laptop, you must immediately disable the machine by long pressing the power button. / turn off the laptop until the battery indicator goes out on the housing. Then remove the battery (where the battery is removable) and attribute it to the service center.

It is strictly forbidden to heat the laptop and independent drying. Even if after drying at home, the laptop will start and there will be no warranty that over time the liquid droplets system fee, do not provoke short circuit And as a result, breakdown the device.

Cleaning keypad

If one or more keys stopped working, you need to clean the keyboard.

Turn off the laptop.

• Previously before cleaning, you need to take a picture of the keyboard so that it is subsequently not confused where the insertion key.
• We use the screwdriver or nail file.
• Alternately remove all the keys. Dust we collect a vacuum cleaner.
• You can wash the keys, it will suit any non-aggressive detergent. It must be previously tested on one key to make sure that the detergent will not hurt the inscriptions on the keys.
• Playground under the keys to clean with wet napkins and ear chopsticks.
• Check all the silicone linings in their places. Insert the keys back and try whether they work.

FN key

The Fn key on a laptop or netbook in combination with the top row keys and some other performs quite useful functions - Reduction / increase volume, screen brightness, enable / disable Wi-Fi and TouchPad, as well as some other functions.

When you press one Fn key, it usually does not happen. It works in combination with other keys.

But if the FN combination with the top function channel keys does not work, it means that it is not enabled or the corresponding software To control the combination of hot keys.

The reason why the FN key combinations do not work this:

• Unidentified drivers to control the FN key combination. In some models of laptops, it must be included in the BIOS.
• She could clog or under the button hit a foreign object (garbage).

First you need to install the appropriate driver. To do this, we go to the site of the manufacturer of the laptop.

We download the desired software, install and use a convenient combination of hot keys.

How to enable the Fn key in bios

At the time of reboot, press the input key to the BIOS with the Enabled value - the multimedia keys will be in priority. That is, the top row keys will perform their multimedia functions, without a combination with the FN key, and function keys F1-F12, will work only when pressed with the Fn key.

For different models Bios menu laptops may differ depending on the firmware.

When entering the BIOS, look for a string, in the name of which will be the word KEY. Sometimes it is - function Key Behavior in some cases - action Key Mode..

• Function Key. - Standard version of the Enabled \\ Disabled function keys.
• Multimedia Key. - Multimedia performance of the function keys to return their standard value, additional pressing of the Fn key is required. Enabled \\ disabled.

To the category

The keyboard clogged - the FN key does not work

Often, a different garbage can fall into the keyboard, from dust to bread crumbs, animal wool, in this case it is enough to clean the keyboard independently or contact a specialist.

Tip: Do not swing drivers and utilities from unverified sources, torrents and file sharing.

Swing the necessary software only from official sites.

Thus, you will protect your from viral infection.

Sometimes the computer fails, which can entail problems with the keyboard display in the system. If it does not start in the BIOS, it greatly complicates the user's interaction with the computer, as in most versions base system Input and output from manipulators only keyboard is supported. In this article, we will analyze how to turn on the keyboard in the BIOS, if it refuses to function there at its physical performance.

If the keyboard operates normally in the operating system, but it does not work until starting it, then this may be several explanations:

• BIOS disabled support for USB ports. This reason relevant only for USB keyboards;
• There was a program failure;
• Were exposed incorrect bIOS settings.

Method 1: turn on support in BIOS

If you just bought a keyboard that connects to a computer when uSB helpthat is, the probability that your BIOS simply does not support USB connection Or for some reason it is disabled in the settings. In the latter case, everything can be fixed fast enough - find and connect some old keyboard so that you can interact with the BIOS interface.

Follow this step by step instructions:

If your BIOS has no items regarding the USB keyboard support, it needs to be updated or buy a special adapter to connect the USB keyboard to the PS / 2-connector. However, the keyboard connected by this method is unlikely to work correctly.

Method 2: Reset BIOS settings

This method is more relevant for those who have previously worked normally in BIOS, and in Windows. In the case of resetting bios settings to factory, you can return the function of the keyboard, but at the same time important settingswhich you made will also be reset and have to be restored manually.

To reset, you need to disassemble the computer case and extract a special battery or to move the contacts.

The above solutions to the problem can be useful only if the keyboard / port does not have any physical damage. If such were discovered, some of these elements need to be repaired.

Hello.

The laptop keyboard stops working as often as the keyboard of an ordinary stationary computer. True, if the keyboard of the usual PC is easily and quickly, you can disconnect and connect a new one (at least for verification), then a laptop is somewhat more complicated ...

In general, the reasons for which the keyboard does not work on a laptop is quite a lot. In this small article I want to disassemble the most common.

1. Installation of malfunction ...

If the keyboard stopped working suddenly, without any serious reasons (for example, a drop in the device) - then the first thing I recommend to do is check, "Is it completely not working" or only in Windows?

The fact is that some viruses and especially drivers (for example, on Bluetooth) in case of failure can lead to a touchpad and keyboard disconnection. Most fast way It is checked - go to the BIOS.

How to enter the BIOS (input keys) -

If you entered the BIOS and the keys there work - Most likely the cause of a fault in Windows. In this case, you can try to boot in safe mode (or with the help) and check if the keyboard works. If it works - the reason in Windows 99.99%! In this case, one of the most simple options solutions to the problem is reinstalling Windows (or search for failure driver, you can learn in device Manager).

Device Manager: There are no drivers.

If you are not included in the BIOS - The keyboard does not work completely and the point here is not in the drivers or Windows crashes. In this case I recommend trying to connect to USB port. Mouse and keyboard and look at their performance. If they also do not work - the problem may be in the burnt chip on the mat. Place (without a service center no longer do).

2. Problem with drivers.

As already said above - a very popular reason for the keyboard failure. It occurs in most cases due to drivers on USB and Bluetooth. To solve it: you can roll back the system (restore), if there are control points of recovery; remove failed drivers; Reinstall Windows.

1. Restoration of the system

Go to the control panel and run recovery (in Windows 8/7: Control Panel \\ All Control Panel Elements \\ Recovery).

2. Delete / install drivers

I have some good articles on this blog. I will give here links to them. In general, you need to: Delete fully crashed driver, and then download drivers from the official website of the device manufacturer.

3. Reinstalling Windows

Reinstalling Windows 7 instead of Windows 8:

3. Is the battery right ...

The fact is that some models of laptops due to a specific design may not work at all correctly with the battery. Those. If it is connected to a laptop and discharged (or just does not work) - then the keyboard can stop working. It is easy to check if you turn off the battery from the laptop and connect it to the network.

Laptop: bottom view (green arrow points to place under the battery).

4. Is the train in order ...

If the touchpad on the laptop works, the connected keyboard and the mouse to USB also work - it is possible in the loop: it could simply move away (or because of non-dense contact, or when moving the device). Also, the cable from the keyboard could be incorrectly attached if you recently removed the keyboard (for example, when cleaning a laptop, and indeed when disassembling the device).

It is also not excluded and the fracture (inflection) of the loop (this may be due to unsuccessful design laptop.

Laptop keyboard: Loop for connecting to the device.

Important! To remove * keyboard from a laptop, pay attention to its outline: from above and below (sometimes with the left and right) sides will be small latches. It is convenient to pry an ordinary screwdriver, and then carefully remove the keyboard. It is necessary to act without hurrying, the train in some models is quite thin and damage it is very simple. If I have never disassembled your laptop before, it is probably worth contacting the service center.

* By the way, in some models of laptops - it is not easy to remove the keyboard, you need to pre-unscrew the additional mount.

5. If several keys do not work

When dust (or small particles, crumbs) under the keys - they can stop hardware. Pretty frequent cause Disability separate keys on keyboard. Fighting this attack is simple: produce cleaning from dust and not to take the device into the kitchen (as many people like to do ...).

6. Spilled keyboard

If the liquid containing sugar or salt (for example, tea or lemonade, juice) is shedding on the surface of the keyboard (for example, the corrosion process will begin. By the way, because of this, not only the keyboard can fail, but also motherboard and others. Laptop devices.

Action at the entity:

1. Disable from the power completely and as quickly as possible (remove the battery from the device housing, turn off the power supply);
2. Turn over the device: so that the liquid all flows down;
3. Do not include the device to complete drying (usually 1-2 days).
4. It is advisable to show the device in service center. The fact is that even if the device will work after switching on, the corrosion process is not excluded, which could begin. And in a short time, the laptop may fail (especially if there were "aggressive" fluid sheds: coffee or tea with sugar, coca-cola, pemps, juices, etc.).

6. Temporary measures

In my opinion there are 2 effective way temporary solution to the problem.

1) Connecting an additional keyboard to USB port (if, of course, they work).

2) Turning on the on-screen keyboard (especially help you, if you do not work 1-2 keys that need to be pressed from time to time).

How to turn it on screen keyboard? Go to " Control Panel \\ Special Features \\ Special Features", Then turn it on.

Good luck!

User's question ...

Hello.

Help with one problem. None of them stopped working the keyboard on my lenovo laptop B70-80. The laptop did not hit, did not flood, did not hit - just after switching on, does not respond to pressing some keys. What can be done?

Good day!

What is good in this regard, a regular computer is a quick change of one keyboard to another. In the laptop such a procedure, unfortunately, you will not check so quickly.

In general, so that neither from this keyboard stopped working - the case is extremely rare. Most often, the user is recognized as the reason (and sometimes links). For example, it is fairly influenced by the keyboard of tea, water, juice; Mechanical damage, etc.

In this article, I will consider the main causes of the keyboard failure, and what can be done to restore the device's performance. So...

Laptop keyboard refused: Causes

What can be done to temporarily correct the situation

I want to start an article from what temporary measures can be taken to at least somehow dial some characters, press the necessary keys (which may be needed during the recovery process).

1. Method number 1. - Connect a USB keyboard. In order for any modern laptop there are several USB ports. By the way, if the USB ports do not work as well - then it is a rather bad sign, may indicate the failed mat. fee;
2. Method number 2. - Call the screen keyboard. It is located in the section: control Panel / Special Features / Center special features (See Screenshot below).

1) Inattention / User Advancement

No matter how ridiculously sounded, but very often the keyboard "does not work" due to the user's ignorance. For example, how many times I complained about the fact that the numbers on the keyboard broke out that the dates are not introduced, etc. - But the fact is that the digital keyboard works when the key is pressed Num Luck (By the way, there is often a LED on it or above it).

So, if this key is not pressed, when you try to enter numbers from a numeric keypad - you will jump the cursor, move, do not react at all.

If you do not work the numbers - be sure to pay attention to this key!

Note: Some laptop models include numeric keypad Only by pressing the keyboard key: Fn + Num Lock.

By the way, another moment: concerns the function keys (F1, F2, F, 3 ... F12). On the modern laptopsTo work out some of these keys - you need to be except for it, still press the FN key. Usually, this moment is configured in the BIOS.

Below in the screenshot is shown "Advanced" laptop dell. - In the "Function Key Behavior" item - there is an opportunity to choose how the function keys will work: in multimedia buttons mode (down / add volume, brightness, etc.), or in mode ordinary features (Update page, call help, etc.).

To consider in detail here how to enter the BIOS and how to configure it will not be, but I will give a couple of links to articles from which you can learn this information:

1. how to enter BIOS -
2. bIOS entry buttons for different laptop manufacturers -
3. how to reset the BIOS settings -

2) Under / between keys

Under the keyboard keys, dust, dirt, crumbs, and in general, the keyboard is saturated with greasy hands, fingers even enough good users. Over time, part of the keys (usually starts with 1-2) ceases to react normally, it is necessary to press with force and crush.

An article about how to clean the laptop / PC from dust. Link to the article section on how the keyboard cleaning from crumbs, fatty traces and dust -

Clean the keyboard (in my opinion) can be three ways:

1. use special USB vacuum cleaner that carefully and carefully can collect most crumbs from the keyboard surface;
2. use special Velcro, which, when you click on them, fill the keyboard plane, and when you post them - all dust and dirt remains on them;
3. you can blow the keyboard using a conventional vacuum cleaner (especially if it has a reverse mode), and then gently wipe with a damp cloth, moistened with soap solution.

3) software failure, error when loading OS

If you do not work at all on the keyboard key at all (and you did not poured it, did not knock it out, etc.), I hurry to assure you, in more than half of the cases - the software is guilty. For example, mg to occur conflict drivers, at the stage of loading your OS or some virus picked up, etc.

The easiest and surest way - try to restart the laptop to start. It will not be superfluous to try to enter the BIOS (as done - see in this article :).

Note: If the keyboard works in the BIOS (and what you entered it, already talking about it) - it means you probably have a reason in software. In case of problems with iron - the keyboard will not work anywhere: neither in the BIOS, nor in Windows or in any other OS!

If after restarting the laptop keyboard does not work again (and in Bios keyboard Worked), try to roll back the system to that condition when she worked. Below I will give a link to the Windows Restore article.

How to restore Windows 10 -

If recovery does not help (or you will not have checkpoints for recovery) you can try. I also recommend paying attention to the drivers, about them just below ...

4) Drivers Problem

In general, usually, the drivers on the keyboard are installed automatically when windows installations. But sometimes the following problems are observed with them:

• On some laptops installed several not standard keyboard with add. functions - and for her full-fledged work Special needs. Drivers. In their absence - the keyboard may not work in full mode;
• Could fail / conflict drivers in the system. Often it happens with USB drivers, on TV tuner, audio drivers, etc.;
• It may have been damaged directly by the keyboard driver themselves.

- How to remove any old or excess driver in system:

- programs for working with drivers: search, update, removal:

5) Covering the contacts of the keyboard cable // Pin damage

If the previous steps did not help anything, and the laptop keyboard also does not react to any of your press - I recommend checking the train. With him, usually happens as follows:

1. if you disassemble the laptop and turned off / connected the keyboard - it is possible that the cable could simply do not insert tightly into the socket. If it happened, try to reconnect the keyboard;
2. it is also often damaged if it is damaged with a neat disassembly of a laptop (the wiring in the loop is quite thin and can be interrupted by one not careful movement);
3. contacts of the loop, or the nests in which he "Sit" could oxidize and not give good contact. Try carefully to wipe them with an eraser (as a rule, contacts even on the eye begin to become lighter, which means you removed the oxidial flare).

IMPORTANT! On some models of laptops, it is not easy to remove the keyboard: for this, it may sometimes be necessary to disassemble the entire device to the bottom! In general, it is usually enough to unscrew a few latch with a screwdriver (see photo above), and lift the keyboard plane.

By the way, if your laptop is on warranty - use the service center service. Your independent disassembly (including the disconnection of only the keyboard) - almost certainly will be the cause of failure in warranty service!

6) Polyting Keyboard Liquid

Some specialists summed up interesting statistics: Each 50th mug over the laptop overturns to it. It suffers at the same time, first of all, the keyboard. By the way, in my own experience I will say that with any admission, the keyboard suffers 100%, but the other devices (under it) still have chances to stay dry: it all depends on the speed of the user's response after the incident, and the amount of spilled fluid.

In general, liquid liquid is dispersed. Especially dangerous for iron liquid containing salt or sugar: tea, juice, lemonade, etc. When such a liquid falls on the contacts and metal parts of the board - then the process of oxidation and corrosion begins, which destroys (in some cases, not immediately, but right) iron.

What if you poured a laptop:

1. turn off the laptop: You can immediately disconnect the power supply and remove the battery, as soon as possible (the faster, the better);
2. next, flip the device so that the fluid began to flow out of it;
3. seeing the device for several days (before - the device simply does not dry). For drying not to use nor hair dryers, nor heaters, nor other similar devices;
4. it is extremely desirable to disassemble the device and see how far fluid penetrated. In general, of course, if they never did it - I recommend showing a device in the service center: because Even if your device will work after drying, the residues of the liquid (especially if it was aggressive: juice, beer, tea, etc.) will slowly and correctly destroy your iron from the inside, causing corrosion and oxidation.

7) Mechanical Damage

In general, by and large, there is nothing to break in the keyboard, and as a rule, the breakdown is associated with damage to some particular key (i.e., 1-2 keys will stop pressed). Usually, it happens if something falls on the keyboard with a laptop, or you accidentally threw a device (such, for example, it could be on the road, when the device is moved).

In some cases, when contacts are damaged on the keyboard board (or the "Clamp" button) - then the keyboard may not respond to pressing other keys, and not stable. By the way, do you have some keys clap, if you can find out any text editor: Word, notepad, etc.

Button "A" hung

By the way, if you do not work 1-2 keys, they can reassign On the other and for some time to use the keyboard (and maybe it will be long?!).

To help! How to reassign one key to another (those who do not work pressing the keyboard button) -

8) What's with a laptop battery?

And the last thing I would like to stay in this article. In general, such a rather rare, but still I met on one "no name" by a Chinese laptop: the keyboard has stopped working on it if the battery is discharged and below a certain minimum of 7%, apparently worked peculiar by (I hope this will not be popular?) .

On this, I complete my opous, for additions on the topic - a large Mercy. Good luck!

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. 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.

It may not be at all in the keyboard, but in a cunning setup Windows. 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, operating system Just "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 entry 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 changes made. Now restart the computer and check the result. Now the keyboard works in normal mode.
