One of the most important components of any computer is the keyboard. The peculiarity of laptops is that it will be very difficult to change it in case of any malfunction - in any case, it is much more difficult than simply removing the plug of an old device and inserting a plug of a new one, as is the case with stationary PCs.
What to do if one or several buttons suddenly stopped working on the keyboard, for example, the top row? Is it possible to correct the situation on my own and what is needed for this? You will learn about all this in this article.
Why SHIFT and other buttons on a laptop may not work
The first step is to determine the cause of the problem in order to decide which sequence of actions will be needed to resolve it.
One of the most common causes is a malfunction of the keyboard itself. This may be due to both the natural wear of the device over time and the wrong connection.
In addition, blockages can occur, especially if you have a habit of eating or drinking while using a computer. The ingress of dirt into the internal device of the keyboard often leads to the failure of one or even a number of keys - zero, arrows, Ctrl, Shift. The latter are located at the very edge of the laptop and are very useful and often used.
The lack of key response may also be due to the presence of various viruses in the system. In such cases, the key can execute either not a complete list of the commands intended for it, or even those that it should not perform.
ATTENTION! The button is also affected by the operating system - if this is a pirated version, then you should not be surprised at the presence of this and any other problems.
Or it may be that some settings in the system are set incorrectly. This problem has the simplest solution of all the ones presented above - you just need to go into the settings and change some important parameters that have a significant impact on the keyboard.
What to do if the Shift button does not work
When the Shift key does not work, the first thing to do is to thoroughly diagnose the device and check the system for viruses.
To do this is quite simple - you need to use a special scanner, which is shared by the manufacturers of the most famous and trusted manufacturers of antiviruses. After checking, it is recommended to install one of them in order to further protect yourself from the appearance of any malicious programs and utilities.
Now remove the viruses found.
Some laptops have special hotkey combinations that make it easy to accidentally switch keyboard modes. As a result, some keys will be either locked or reassigned - this means that they will perform completely different functions that are not intended for them. In this case, you need to return to the old mode, finding the hot keys that work on your laptop model.
If the keyboard is clogged, it is necessary to disassemble it and carefully clean it. On the Internet there are a large number of instructions for disassembling the keyboards for each laptop, which can differ significantly from each other.
You will need to do the same if the control panel is broken. You may need to replace one of the contacts or the cable inside.
IMPORTANT! If you have a pirated version of the operating system, you will need to reinstall it. To do this, you need to find a quality version in which there will be no problems with the operation of the button.
Actions if several buttons on the keyboard do not work
In general, all actions aimed at restoring the keyboard can be divided into two groups:
- physical methods;
- software methods.
If several keys do not work at once - Ctrl, with letters, then the keyboard does not need to be completely changed at all. Therefore, we consider in detail some ways to return it to operation.
Physical methods
Physical methods include pressing certain keys, cleaning and actions associated with the need to disassemble the device.
In the first case, you can try to hold Fn and Num Lock. Usually this combination allows you to return the control panel to the desired mode.
If this does not help, you need to remove the keyboard with a screwdriver. Before doing this, be sure to turn off the device and remove the power source from it. In the presence of obvious mechanical damage, you will need to replace the keyboard cable.
Under the plate is a microcontroller. It should be cleaned and thoroughly dried.
Software Methods
In addition to reinstalling, you can also try changing some keyboard settings. It is possible that the drivers are out of date - in this case, you just need to download them from the official website of the manufacturer for your laptop model and version of Windows.
In the Control Panel, you can find the "Keyboard" and make sure that all the necessary functions are connected.
In addition, there is a way to return the system to the level where everything worked correctly. To do this, find the "System Restore" item in the Control Panel. After sure, restart your computer.
Now you know why the keys on the laptop keyboard may not work and what you can do yourself in this case.
