Some buttons on the keyboard do not work

Over time, everything breaks sooner or later. This is especially true for computer equipment such as keyboards. Often the keyboard stops working at all or some buttons do not function on it. What is the reason and how to fix it so as not to spend money on a new keyboard and not repeat mistakes? Let's look further.

If some keys on the keyboard do not work

The keyboard and one or more of its buttons do not work for the following reasons: driver damage, exposure to a virus or settings errors, sticking, loose contacts, and contamination. Sometimes water occurs as a result of some keys not working, but often in this case the entire keyboard does not work.

What should be done in the above cases? There are a number of simple things to do:

1. Check to see if the connector of the wire of the device that connects it to the computer has fallen out; if it has fallen out, insert it back and restart the PC;
2. See if Num Lock (on a laptop) or F-lock (on a desktop computer) is turned on - it should be turned off;
3. Update device drivers and scan the entire system for viruses. If viruses are found, remove them or reinstall the system;
4. Clean the buttons from dirt and sticky stains by disassembling the device into parts.

Attention! In cases where the functional buttons on top and all other programs do not work, you should reinstall the system.

Also, some buttons do not work due to the PC system being in safe mode. This means that the drivers are looking for a problem and a virus. When they finish their work, you should remove 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.

Reasons for the keyboard not working correctly

Incorrect operation of computer equipment occurs due to mechanical and software reasons. Mechanical cause is a broad concept that includes breakdowns in the form of a cable break, moisture ingress, excessive dirt, damage to the integrity of ports, problems with contacts coming out, mechanical damage to the cable, etc. Software cause is software failures with incorrect BIOS settings, viruses, incorrect operation drivers, etc. In any case, the device needs to be repaired and problems resolved to continue working. To do this, you can contact the service center or try to solve the difficulties that arise yourself.

Dirt and liquid

Dirt and spilled liquid on the keyboard is the most common reason why buttons become faulty. Often people type at the computer and drink tea, coffee and other drinks. As a rule, nearby drinks spill on a vulnerable spot in computer equipment—the keyboard. As a result, it breaks.

Mechanical damage due to dirt or liquid is easily identified by specialists and repaired. Anyone can do this too.You should do five simple steps: visually inspect the extent of damage to the device, remove the keys, clean, dry and reassemble. In 90% of cases, the keyboard begins to display printed characters. If it doesn't work, there is only one way out - buy a new one.

Damage to the cable

Damage to the cable is a more serious breakdown problem, for which people go to specialists. A cable is the wires that are located inside the keyboard and connect the printed circuit boards and all additional electronic elements together. Wires have a large list of varieties and soldering features due to the unusual arrangement of contacts. Therefore, repairs to cable failures are carried out in service centers.

Damage occurs due to constant use of the device, rough handling and sticking keys. The frayed and broken cable is replaced. To do this, take a copper wire suitable for the cross-section, peel off the varnish layer and remove the wire. A new one is installed to replace it. It is fixed using conductive glue and technical varnish. The recovery process takes about an hour. The main thing is to treat the contacts well with improvised means.

Software reasons

Keyboard failure due to software reasons can be due to a software failure, a damaged driver, a virus on the computer, or incorrect operation of drivers or the entire system. Often it also does not work due to the PC being in safe mode and due to inconsistent assembly order with system startup.

Troubleshooting

All problems that arise can be resolved independently or with the help of IT specialists. You can independently fix, for example, software failures, viruses and driver malfunctions.Failures and malfunctioning drivers can be removed by restarting the computer or reinstalling the system. Viruses can be cleaned by running a licensed anti-virus 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 games on a PC become faulty. As a rule, these are space, enter, tab, shift, numbers and F series buttons, arrows (down, up), letters, print screen, windows button. The most problematic is repairing the spacebar key. This is the longest button and has a metal bracket attached to it that is inserted into the slots in each key support. The bracket must be placed in the slot without pressing, since if it is deformed, it will not be possible to put the key in place. Thus, this is a complex process that not every repairman undertakes.

As for the other buttons, there are no problems with them: if they break down, they can simply be replaced with others, as well as repaired.

In general, the keyboard breaks for various reasons: mechanical or software. To avoid mechanical breakdowns, you should be as careful as possible with buttons and equipment. To avoid repetition of software errors, it is worth remembering a number of the tips listed above.
