Some buttons don't work. What to do if the buttons on the keyboard do not work. Latest tips from the Computers & Internet section

When keys don't work on a packard bell, acer, asus, toshiba, Lenovo, Samsumg, or HP laptop, the situation is not very pleasant.

Usually the first thing that comes to mind is to take it to a service center. But don't rush. A lot of things you can fix yourself.

It is very bad when some function keys on a laptop (packard bell, acer, asus, toshiba, Lenovo, Samsumg HP - Compaq) do not work due to track malfunctions.

You can draw them yourself, only this work is delicate and not everyone can do it.

In almost every laptop (modern) (keys) you can disassemble and see what's what.

It is not worth disassembling the laptop completely, the keys can be removed one at a time. A good way to remove the keys, my son (2 years old) suggested to me - with a fly swatter.

After hitting the keyboard, six keys popped out of their sockets on their own, and remained completely undamaged. This is the only method I would not recommend.

Some keys will not work if dust gets under them. In this case, you need to clean. You can try to blow (without removing) with a strong air pressure, but usually this does not help - you have to remove it.

Typically, the keys on a laptop consist of three elements: a platform, an elevator and a spring element and are connected by latches.

If they are easily lifted with a thin screwdriver, they can be removed. After that, clean the platform and install it back. There is no difficulty in this - it is available to everyone, you can not be afraid.

The situation is much worse if the keys were flooded with liquid that damaged the tracks - most will have to send their laptop in for repair.

If one or more keys do not work, with the impossibility of self-restoration, then you can assign their functions to others that are practically not used. Yes, it is inconvenient, but you can use it for a while.

Remember, if some keys on the laptop do not work, then any of them can be assigned independently absolutely any function.

This can be done manually by changing the register, (so difficult and not everyone can do it) or use a simpler method by downloading the special AutoHotkey program.

This program is not the only one, but if it exists, then others will not be needed. On the right side are keys that are used very rarely, and most do not pay attention to them at all.

Assign the missing functions to them, stick stickers with the designation (so as not to be mistaken) and use them until you decide what to do with the keyboard in the future.

• By the way, there are also online services and special programs with which you can check (test) the keyboard for errors. You can download the program or use online resources

Also keep in mind that keyboards are not expensive, one might say, they cost a penny, and you can easily connect an external keyboard to a laptop or netbook, and not just change it. It's just inconvenient to take it with you.

When they do not work on a laptop, there is another way to solve the problem - use a virtual one.

To call the virtual keyboard, press "start" (windows logo, at the very bottom left), then find and click "all programs" at the bottom, scroll down the menu to the very bottom and select "standard", then go even lower and click "accessibility"

After that, find a virtual keyboard and run it - there will be no difficulties. For those who write little (only in Yandex or Google), this option can even be used on an ongoing basis.

In any case, now you know what to do when the keys do not work on a packard bell, acer, asus, toshiba, Lenovo, Samsumg or HP - Compaq laptop.

The reasons

We list the main reasons why some keyboard buttons do not work on a laptop:

1. contacts are damaged by corrosion;
2. worn out rubber shock absorber;
3. some foreign object got under the button.

The easy way

To restore the operability of the information input device (any part of it), you do not need to panic, thinking that the situation cannot be more complicated. In most of its cases, it is solved very simply, namely:

1. press in turn on Fn and Num Lock, then release both;
2. walk with a brush / special vacuum cleaner, thereby removing the accumulated dust / debris;

The problem with the digital part of the "clave"

The information input device (or rather, its right side, where mathematical signs are located) is called "digital". With it, you can type any notation and even perform a number of mathematical operations.

Why the numbers on the right do not work on the keyboard, and how to fix the situation? There are several reasons, and therefore solutions:

1. Turn off the digital part.

Press Fn + Num lk or Num lk (Num Lock) and everything will work.

2. The settings are set incorrectly.

Click "Start", then - "Control Panel", and then like this: "Ease of Access" → "Ease of Access Center" → "Make the keyboard easier to work with" → Control the mouse using the keyboard" → "Enable pointer control from the keyboard" (checkbox remove) → "OK".

What about some broken keys?

Let's consider why some buttons on the keyboard do not work (in particular, F1-F12).

If you are the owner of a laptop, then know that Fn is responsible for turning on the keys. If nothing has changed, try to solve the problem through the "Office" button. You may also need to reinstall the drivers.

Letters instead of numbers

The PC can also throw up such a situation: why some keys do not work on the laptop (or rather, letters are printed instead of numbers). It also happens like this: in the Latin register, numeric and alphabetic designations appear immediately, but in the Cyrillic layout - extraneous characters. What is done in such cases?

We act like this: you need to turn off the digital mode using Num Lock and Fn. You have to press at the same time. Look at the result. Letter designations should return.

Or so. In the "Accessibility" section, which is on the control panel, you need to turn off the checkbox for controlling the mouse cursor.

Now it’s clear why some keyboard buttons do not work on a laptop. If not, then you can not do without the specialists of the service center.

Why is the sound not working on the computer

A fairly common problem with a non-working PC is a problem with acoustics. It is necessary to distinguish why the sound on the computer disappeared if the speakers work, but there is no sound. This can happen for hardware and software reasons.

Usually, all buttons on a laptop keyboard do not work due to mechanical failure. If this happens, then you need to completely replace the keyboard.

However, if some buttons on the laptop keyboard do not work, this can be fixed. In this article, we will tell you several ways to fix non-working buttons on a laptop keyboard.

Function buttons not working

The function buttons are the F1-F12 keys. They perform various functions, for example, increase or decrease the volume, disable the touchpad, enable Wi-Fi, and more. They usually work by pressing the Fn key + the desired function on F1-F12 at the same time.

If the function buttons on the laptop keyboard are not working, the problem may be that you have the F-lock button enabled. Take a good look at your keyboard, find the F-lock button, and press it to turn it off. If you do not have such a button, then your laptop does not have the ability to disable the operation of the function buttons.

Numeric keypad buttons not working

The numeric keypad is located on the right side of the laptop's main keyboard. It has this name because it offers quick access to numbers from 1 to 9. If some buttons on the laptop numeric keypad do not work for you, then try press the Num Lock key.

Keyboard buttons do not work in one specific program

Some keys on the keyboard do not work with all programs, such as function keys (F1-F12). An easy way to check if the buttons work in other programs is to open Notepad, Word or an Internet browser, and then click on the buttons of interest.

Restart your computer and enter safe mode

If your laptop is running Windows, try restarting it and booting into safe mode. If the buttons on the laptop keyboard work in safe mode, this indicates that one of the installed programs or drivers is causing the problem.

Clean your keyboard

Dust, dirt, hair, and other objects can get into the laptop keyboard over time, thereby making it difficult for the buttons to work and causing them to work incorrectly, or not work at all.

If none of the methods above solved your problem, the keyboard is probably defective and needs to be replaced. In this case, you need to contact the service center and find out the reason why some buttons on the laptop keyboard do not work.

A common reason why some laptop buttons have stopped working is due to damage to the keyboard board tracks of the device or a significant amount of debris accumulating. Below we will tell you what to do in this case - how to disassemble the laptop for cleaning, restore damaged tracks and eliminate others, including software causes, which may cause the above malfunction.

If the laptop keyboard was flooded

If, as a result of negligence, the device's keyboard was flooded, it is important to quickly turn off the power to the device, remove the battery and clean and dry, after disconnecting the input device. If you neglect cleaning, then over time, some tracks may rot, as a result of which you will have to make quite difficult repairs - one or more buttons may simply stop working.

Consider how to disassemble a laptop for cleaning in the case described above:

1. Unplug it and remove the battery.
2. Remove the input device, for which:

Dismantle the buttons and clean the keyboard

To remove the key without damaging the device, you usually need to lightly press it from above, and pry it off from below with a thin screwdriver. It all depends on the laptop model. The buttons here are attached to the latches to the so-called. elevator.

The number of fasteners can be from three to four. In the first case, only one connection will be movable - upper or lower, in the latter - both connections will be movable. We are primarily interested in the fixed connection of the elevator. It is from this side that you will need to pry if you want to safely snap it off. More often fixed connections are located in the lower part. Then just pull the tool up.

After dismantling all the buttons, you can proceed directly to cleaning. You can work with simple wet wipes. You can also use various cleaning fluids, with the exception of aggressive ones - acetone, etc., which can easily damage the circuit. After removing all contaminants, assemble the device - this must be done in reverse order.

With installation, there will also be no special difficulties:

• on the spring-loaded element in the center, lower the pad of the key;
• press it strictly vertically down until it clicks.

The device will start to work normally if the accumulated debris was the cause of the malfunction. Otherwise, defective board tracks may be the likely cause. You can also repair them yourself if the damage is not very extensive.

Restoring the tracks on the keyboard board

In the case of faulty tracks, the device will have to be completely disassembled. It will be necessary to repeat all the described steps, and then dismantle the elevators. They are shown in the photo below.

With the last action, difficulties should not arise, since they are removed quite simply, especially from the fixed side.

After all the elevators have been removed from the input device, it will be possible to dismantle the part of the input device from the aluminum substrate.

The polyethylene board with tracks is also removed. On older laptops, you will also need to dismantle the plastic edging. Before this, it is desirable to heat the part with an ordinary hair dryer. Subsequently, at the assembly stage, ordinary superglue can be used to secure the plastic and restore the fasteners.

Next, we will work with a polyethylene board on which the tracks are drawn. The problem is that the track board includes two plates, so to start the repair, these layers also need to be disconnected:

New tracks are drawn directly on top of the rotten ones, but the entire area will need to be thoroughly cleaned of dirt before that. After the updated track dries, it will definitely need to be “ringed out”. The polyethylene part can be collected no earlier than an hour and a half after the described actions.
Next, the repaired layer is laid on an aluminum substrate, and on top - a part with spring elements. You can check the performance right now by connecting it to a PC and opening, for example, a regular notepad. If everything works fine, continue collecting the device, remembering to turn off the laptop before that.

Check for obvious causes that could be causing the problem

But before you start disassembling and cleaning the keyboard, first make sure that the reason why several buttons stopped working is not caused by your inattention or other obvious things. For example, if the laptop does not respond to pressing numbers, check that you have not accidentally touched Num Lock, which is responsible for disabling this block. On some laptop models, a combination of Fn and Num Lock is supported.

Sometimes problems with devices can be software. For example, the driver responsible for its operation may be corrupted due to a virus. The first step in this case is to scan the system with a regular antivirus, or it can be one of the specialized utilities, for example, the free Virus Removal Tool from Kaspersky Lab. Then reinstall the required drivers.

Temporary replacement of the physical keyboard

To be able to download an antivirus program on the Web and perform some other elementary operations on a laptop without a physical keyboard, you can use a virtual one. You can activate it through the "Start":

• in this menu, select the accessibility section;
• click on the line "On-Screen Keyboard".

To enter the desired characters, simply click on them with the mouse. Starting with the eighth version of Windows, instead of the standard screen, you can use a special touch gadget for a laptop or tablet. It also works without a touch screen - clicks are also made with the mouse.

Activation occurs as follows:

• click the mouse to call the context menu of the taskbar (bottom strip of the screen);
• select "Properties" from the menu;
• in the properties of the taskbar, open the "Toolbar";
• Check the "Touch keyboard" option and click "Apply".

Now that at least the virtual keyboard is working, you can download the necessary drivers from the manufacturer's website and remove the faulty driver in Device Manager. If you are having difficulty finding the right program, you can download one of the free so-called. driverpacks with a huge database of fresh drivers. You can use products such as DriverPack Solution or Slim Drivers - they will carry out all the necessary updates automatically.

The modern way of life requires incredible mobility and speed of action. Today, a laptop becomes our indispensable assistant. An Internet connection in tandem with an electronic device makes a person feel almost omnipotent. However, there is another side of the coin here - a person becomes dependent on electronic technology. And this is an obvious fact!

Technology in the hands of a savage...

If at the most crucial moment the laptop fails, some buttons do not work, or the battery runs out, then such a turn of events can lead to the development of a completely unrosy scenario. Especially if you take into account the moment of the online transaction or the bank transfer transaction.

A careless movement of the hand - and you watch with horror as coffee from a cup spilled onto the keyboard of your favorite laptop. Subsequent resuscitation actions will not lead to anything significant. The all-pervading liquid would still prove its destructive power. After some time, you will be convinced by turning on the unit that the buttons on the laptop do not work. You may not want coffee for a long time after that...

In the two cases described above, the laptop, of course, is not to blame. Our human arrogance, some fussiness and, of course, extreme inattention are to blame for everything. Of course, technology is designed, first of all, to help people and facilitate some processes. Therefore, the purpose of this article is to help you properly respond to unexpected manifestations of "user fate". After all, he who has knowledge is armed!

What to do and where to run?

According to the laws of physics, a liquid that is inside a working electronic device can completely disable the entire laptop or individual hardware parts of the device. In our case, the affected element was the keyboard. Since the laptop keyboard module is attached to the case with some structural elements of the laptop and connected to the motherboard using a short cable, the process of dismantling the damaged part on your own can have a deplorable effect on the cost of further repairs. Therefore, the very first thing that the owner of the electronic assistant should do when liquid gets inside the computer is to disconnect the battery and contact the service workshop.

1. Buttons and touchpad not working and you need to finish an important task? Moreover, the work done is on the hard drive of the laptop, and you have already lost all hope for a favorable outcome? There is an alternative method that allows you to control through the laptop interface.

A standard USB keyboard inserted into the laptop connector will definitely help resolve the situation.

2. If the keyboard does not respond to key presses, make sure that none of the device's buttons are stuck or mechanically damaged.

3. If the buttons on your laptop do not work, most likely the system requires certain drivers, since some service keys function only after installing specialized "firewood". Usually this is a laptop: volume, navigation buttons, etc.

4. Very often, the reason that the buttons on the laptop do not work is the operating system itself. Reinstalling the OS is a viable solution to verify if a software glitch is the source of the problem.

5. In some cases, a burned-out microcontroller may be the culprit for the incapacity of the keys. In such a situation, a visit to the service center cannot be avoided, since the laborious process of replacing a part requires specialized knowledge and experience in installing a damaged element.

Finally

If the above guide did not help, and the buttons on the laptop still do not work, you should not try to disassemble the unit yourself and use the "poke" method. Manipulation by inexperienced hands can lead to quite serious problems. It is better to turn to professionals. Very often, the elimination of this malfunction costs the owner of a laptop a penny. Do not get upset ahead of time and expose your beloved computer to the risk of being destroyed with your own hands!
