Some buttons do not work on the laptop keyboard

Damage to the keyboard for a personal computer is, of course, unpleasant, but not critical for the entire device. The keyboard on it can be replaced. As for the laptop, such a number will not work with it. If the keyboard is damaged, you need to either repair it or purchase a new one.

Why the buttons on the laptop keyboard do not work

The reasons for this failure can be different. Here are the main ones:

  • A defective device is the simplest reason. Now it is quite rare, but it still has a place to be. It appears immediately after the purchase of the device. One or two buttons may not work, rarely - completely. It is recommended to return such a laptop back from where they brought it.
  • Error in the system - the operating system installed on the device can not cope with the load. Despite the fact that the computer industry has been developing for a long time, computers are still unstable. An error can occur due to hardware imperfections or due to the activity of viruses. Signs of such an ailment - the entire keyboard is turned off, perhaps not only it. Rebooting and then cleaning the computer will help to cope with the trouble.
  • Damage to chips or a board is a more complex problem. It affects the physical shell of the device. To find out if this is your case, you should check the operation of the charger input, USB input and touch panel. If they do not show signs of life, then you need to go to a technical assistance service. Perhaps the microcircuit will be partially damaged, which will explain why half of the keyboard on the laptop does not work.
  • Damage to the loop - problems with the interaction between the hardware and the monitor. This reason is manifested by a sharp shutdown of the keyboard, but the proper operation of other elements of the laptop. You can try to open the laptop yourself and fix the cable.

ATTENTION. If you have never had to disassemble electronic devices - tablets, laptops, system units of computers - and you are not sure that you can do it right, then it is not recommended to experiment with your laptop. It is better to provide an opportunity for a specialist to deal with trouble.

  • Lack of drivers is a fairly rare reason. In most situations, the keyboard on the laptop does not require additional software. This problem is solved by removing old drivers and installing new ones.

The keyboard on the laptop partially does not work

The situation when not the entire keyboard, but some keys stop working, is not so common. Most likely, these are foreign objects. The presence of pieces of food or liquid between the buttons explains why part of the keyboard on the laptop does not work. Even if the user does not have a habit of chewing behind the monitor, all the same, over time, dust accumulates between the buttons. It can be disassembled and cleaned independently, or it can be taken to the technical support center.

What to do if some buttons do not work on the laptop keyboard

The answer is simple - try to fix the breakdown yourself or take it to the service so that the specialists “cure” the computer there. Below you will find options for self-repair.

Simple Ways to Solve a Problem

The keyboard has its own lock. It is possible that the user accidentally locked their keys. Depending on the modification of the device, in order to unlock the buttons, it is necessary to hold down Fn + NumLock, FN + Pause, Fn + Win or a special button with the image of the lock, if any. If the buttons then begin to work, it means that the problem was solved.

Alternatively, you can try to clean the keys with a brush, or use a special vacuum cleaner designed for keyboards. Such an event will help get rid of the problem if the laptop is clogged with dust and the signal from the keys to the system does not pass.

Fix a software crash

Simple methods did not help, so you need to try to solve the problem at the software level. Incorrect operation of programs or the driver may affect the response of several buttons or the entire keyboard. The list of actions for verification and correction:

  • Start the laptop and when the first window appears, press F8. It is not always this key that brings up the download menu; different versions of operating systems may use different keys. If F8 does not produce a result, then you should try pressing other F. The result should be the "Advanced boot options" window.

  • Using the arrows or additional navigation buttons on the screen (rare laptop models are equipped with them), select "Safe Mode" or "Start in Safe Mode". This will allow you to start the system without using drivers.
  • It remains to check the operability of each key on the laptop, regardless of which of them worked before and which did not. It is enough to use the online keyboard button check service. To find it, just enter in the search engine "Key-test" and select the first available link. In such services, each key pressed is displayed, which will help to easily check the serviceability of each button.
  • If in safe mode the buttons show proper operation, then the malfunction really lies in the system. In this case, you need to step further down the list. If some of them do not work, or work unstably, then the software shell has nothing to do with it.
  • To fix system problems, you can try updating the driver. After starting the system in normal mode, in the "Search" menu of the "Start" menu, enter "Device Manager". If the required letters on the keyboard do not work, then you can try to enter a similar query in the browser search engine, and it will fix the errors, then copy the corrected version (Ctrl + C by default) and paste it into the search field (Ctrl + V). Or just copy any letters from any text on the Internet and use them.
  • From the items found, select the desired service.
  • A window will open in which you should select the item "Keyboards" and, having selected one of the positions, right-click. A list appears where the user will find the "Update drivers" item useful. After that, a question pops up about finding drivers, where you need to select "Search for drivers on the network."
  • These actions must be repeated for each position, if there are several. Some keyboards are indicated by several names, but this is rare.
  • If the system decided that new drivers are not required, then you must remove the old one and download the new software. This can be done there, in the device manager, by selecting "Delete" in the drop-down list.
  • After that, the automatic installation of drivers on the keyboard should begin. If this does not happen, turn off the laptop and turn it on again. The system will detect a new device without drivers and try to install them.

Updating drivers is also possible using a variety of programs that independently detect all the software in the system that needs to be updated. If, after reinstalling the drivers, the problem with the non-working keys is not resolved, then the problem is not in the software sphere.

Fix a physical failure

This option involves disassembling the laptop and eliminating the physiological cause of the failure. If you are unable to disassemble and properly assemble the electronic device, it is better not to risk it, and consult a specialist. The sequence of actions is as follows:

  • Turn off the laptop completely and remove the battery. The battery is usually located at the bottom of the device, closer to the fold of the monitor. The laptop at this moment should not be connected to the mains, and, in general, it is advisable to remove all additional devices from it.
  • Open the latches of the upper plate with a simple screwdriver, needle, knife or any other narrow object. Latches are located on the edges of the pad with buttons, they can be found quite quickly. If there are no latches, then you should pay attention to the instructions that came with the laptop - perhaps it says about how to open the laptop.

  • You don’t need to immediately pull the plate with the buttons - it is attached to everything else with the help of a loop, and sudden movements can damage it. The plate must be carefully lifted and, taking on the plastic part of the cable, disconnect it from the remnants of the laptop. If noticeable damage is found on the loop, it must be replaced (most likely, the problem is in it). Touching the loop with wires is strongly discouraged - only plastic.
  • The plate covers a microcontroller. This is a special tool that provides signal transmission from the buttons to the PC reader. If dust or humidity is noticeable on it, then these factors must be eliminated - they can cause the laptop to work poorly. It is not difficult to find out the microcontroller - this is the part on which the loop was attached. If there is damage visible on this part with the naked eye, it must be replaced.
  • After that, you need to disconnect each key individually (with the same thin object that was used to open the laptop), and then clean the surface of the plate. If the buttons are damaged, it is better to replace them - purchase spare parts.
  • After thorough cleaning, you need to repeat all the steps to disassemble the laptop keyboard in the reverse order and check the operation of the buttons. If this does not help, then it is better to use the technical support of specialists.

How to do without some buttons

If there is no way to solve the problem with several idle keys, then you will have to take advantage of what is available for a while. Options for recovering missing letters:

  • Create a text document and copy the necessary letters from the Internet there, and copy them from there as necessary.
  • Use automatic word correction in Microsoft Word or online resources.
  • Download the virtual keyboard, or find one online.

In any case, the lack of some keys does not put an end to the entire laptop. In most situations, the problem can be solved or adapted.
