Some keys on the keyboard do not work

With the passage of time, all things eventually deteriorate. This is particularly applicable to computer equipment like keyboards. Frequently, keyboards completely cease to function or some of their buttons become unresponsive. What is the cause behind this and how can it be remedied in order to avoid spending money on a new keyboard and repeating mistakes? Let’s delve further into the matter.

There are several reasons why the keyboard and its buttons may not be functioning properly. These include damage to the driver, the presence of a virus or errors in the settings, sticking of keys, loose contacts, and dirt. In some cases, water damage may also result in a loss of functionality for certain keys, although it is common for the entire keyboard to stop working in such situations.

What can be done in these situations? There are several simple steps you can take:

1. First, check if the connector of the device’s wire that connects it to the computer has come loose. If it has, insert it back securely and restart the PC.
2. Ensure that Num Lock (on a laptop) or F-lock (on a desktop computer) is not enabled – it should be turned off.
3. Update the device drivers and scan the entire system for viruses. If any viruses are detected, remove them or reinstall the operating system.
4. Thoroughly clean the buttons, removing any dirt or stickiness by disassembling the device if necessary.

Attention! If none of the function buttons or other programs work, it may be necessary to reinstall the operating system.

Additionally, certain buttons may be unresponsive as a result of the PC system being in safe mode. This indicates that the drivers are scanning for any issues and potentially a virus. Once they have completed their tasks, it is necessary to disable safe mode in order for the buttons to function properly again. In the event that the buttons remain unresponsive despite these measures, it is advisable to either restart the computer system or perform a reinstallation of the Windows operating system.

Causes of incorrect keyboard operation

Computer hardware malfunctions can occur due to various mechanical and software issues. Mechanical problems encompass a wide range of factors such as cable breakage, moisture damage, excessive dirt accumulation, port integrity issues, loose contacts, and physical cable damage, among others. On the other hand, software issues can arise from incorrect BIOS settings, virus attacks, faulty drivers, and more. Regardless of the cause, it is necessary to repair and resolve these problems in order to restore the proper functioning of the device. This can be achieved either by seeking assistance from a professional service center or by attempting to troubleshoot and solve the issues independently.

Dirt and spilled liquids are the most common causes of keyboard malfunction. Often, people use their computers while drinking tea, coffee, or other beverages. Unfortunately, these drinks often spill onto the keyboard, causing it to break.

Specialists can easily detect and repair mechanical damage caused by dirt or liquid. However, this is also a task that can be performed by anyone. There are five simple steps that should be followed: visually inspect the extent of the damage to the device, remove the keys, clean them, dry them, and reassemble the keyboard. In 90% of cases, this will fix the issue and the keyboard will function properly again. If this doesn’t work, the only solution is to purchase a new keyboard.

Loop damage

The problem of loop damage, which requires the attention of specialists, is a more serious issue compared to breakage. Loops are wires that are situated inside the keyboard and serve to connect the circuit boards and all additional electronic components. Due to their unique placement, wires come in a variety of types and require specific soldering techniques. As a result, service centers are responsible for repairing loop breakage.

Breakage occurs as a result of regular device usage, rough handling, and keys getting stuck. When the loop becomes frayed or broken, it needs to be replaced. This involves taking a copper wire with a suitable cross-section, removing the varnish layer, and replacing the damaged wire with a new one. The new wire is secured in its place using conductive adhesive and technical varnish. The restoration process typically takes around an hour, with proper treatment of the contacts being a crucial aspect.

Software-related issues can lead to keyboard failure, which may result from a software malfunction, a corrupted driver, a computer virus, incorrect driver operation, or overall system errors. Additionally, keyboard functionality may be compromised when the PC is in safe mode or if the system boot sequence is not properly configured.

How to troubleshoot

Any issues that may come up can be resolved either on your own or with the assistance of IT professionals. For instance, program malfunctions, virus infections, and driver glitches can all be addressed by the user. A simple restart of the computer or system reinstallation can often fix software crashes and driver malfunctions. Removing viruses can be done by running a licensed antivirus program. In the event that this doesn’t resolve the issue, a system reinstallation, like in the previous case, may be necessary.

Which buttons most often stop working

Most commonly, the buttons utilized during virtual or downloaded games can become defective. Typically, these include the spacebar, enter, tab, shift, number and F-series buttons, arrows (down, up), letters, printscreen, and the Windows button. The most troublesome issue to fix is the space bar key. This key is the longest one and has a metal bracket attached to it that is inserted into the slots of each key support. It is important to insert the bracket into the slots without applying any pressure, as any deformation may prevent the key from fitting properly. Consequently, this is a complex process that not every technician is willing to tackle.

As for the remaining buttons, there are no difficulties with them: they can be easily replaced with other buttons in case of damage or repaired when needed.
