Over time, sooner or later everything breaks down. This is especially true for computer hardware such as a keyboard. Often the keyboard stops working at all or some buttons do not work on it. What is the reason and how to fix it so as not to splurge on a new keyboard and not repeat mistakes? Let's consider further.
If some keys on the keyboard do not work
The keyboard and its one or more buttons do not work for the following reasons: damage to the driver, exposure to a virus or errors in the settings, sticking, contact drift, and contamination. Sometimes water becomes the result of the lack of operation of some keys, but often in this case the entire keyboard does not work.
What should be done in the above cases? A number of simple things should be done:
- Check if the wire connector of the device that connects it to the computer has fallen out; if it does, insert it back and restart the PC;
- See if Num Lock (on a laptop) or F-lock (on a desktop computer) was turned on - it should be turned off;
- Update device drivers and check the entire system for viruses. If viruses are found, delete them or reinstall the system;
- Clean the buttons from dirt and sticky stains by taking the device apart.
Attention! In cases where the function buttons on top and all other programs do not work, you should reinstall the system.
Also, some buttons do not work because the PC system is in safe mode. This means that drivers are looking for a problem and a virus. When they finish their work, you should remove the safe mode and the buttons will work again. If the buttons do not work after these steps, it is recommended to restart the computer system or reinstall Windows.
Keyboard Causes
Incorrect operation of computer hardware is due to a mechanical and software reason. The mechanical reason is an extensive concept, which includes breakdowns in the form of cable breakage, moisture, excessive dirt, impaired port integrity, problems with the contacts coming off, mechanical damage to the cable, etc. Software reason - software malfunctions with incorrect BIOS settings, viruses, incorrect operation drivers, etc. In any case, the device needs repair and troubleshooting to continue working. To do this, you can contact the service center or try to solve the difficulties yourself.
Dirt and fluid
Dirt with spilled liquid on the keyboard is the most common reason why buttons become malfunctioning. Often people type at the computer and drink tea, coffee and other drinks. As a rule, nearby drinks spill onto a computer hardware vulnerability - the keyboard. As a result, it breaks.
Mechanical damage by dirt or liquid is easily determined by specialists and repaired. Everyone can also do this. Five simple steps should be done: visually inspect the degree of damage to the device, remove the keys, clean, dry and reassemble. In 90% of cases, the keyboard begins to display printed characters. If she did not work, there is only one way out - to buy a new one.
Loop damage
Damage to the loop is a more serious breakdown problem that goes to specialists. A loop refers to wires that are located inside the keyboard and connect printed circuit boards and all additional electronic elements together. Wires have a large list of varieties and features of soldering due to the unusual arrangement of contacts. Therefore, the repair of the breakdown of the loop is done in service centers.
Damage occurs due to the constant use of the device, rough handling and sticky keys. The frayed and broken train replace. To do this, take a suitable copper wire for the cross section, strip the varnish layer and remove the wire. Instead, a new one is put. It is fixed with conductive glue and technical varnish. The recovery process takes about an hour. The main thing is to handle contacts well with improvised means.
Program reasons
Keyboard failure due to software reasons is due to a software failure, a damaged driver, a virus on the computer, incorrect operation of the drivers or the entire system. Often, it also does not work because the PC is in safe mode and because of an inconsistent build order with the system starting.
How to troubleshoot
All arising problems can be eliminated independently or with the help of IT-specialists. You can fix it yourself, for example, a software crash, the action of viruses and driver problems. Failure and a malfunctioning driver can be eliminated by restarting the computer or reinstalling the system. Viruses can be cleaned by running a licensed antivirus system. If it does not help, then, as in the first case, you will need to reinstall the system.
Which buttons most often stop working
Most often, the buttons used during virtual or downloaded to the PC games become malfunctioning. As a rule, this is a space, enter, tab, shift, numbers and buttons of the F series, arrows (down, up), letters, printscreen, windows button. The most problematic is the space bar repair. This is the longest button to which a metal bracket is attached, inserted into the slots of each key support. The bracket must be put into the slot without pressing, because in case of deformation, it will not be possible to put the key in place. Thus, this is a complex process for which not every repairman undertakes.
As for the other buttons, there are no problems with them: they are easy to replace with other ones in case of breakage, as well as repair.
In general, the keyboard breaks for various reasons: mechanical or software. In order not to cause mechanical damage, it should be as careful as possible about the buttons and technology. For the absence of repetition of software errors, it is worth remembering a number of the tips listed above.
