In this review, we will talk about how to unlock / lock the laptop keyboard.

How to unlock a laptop keyboard?

If you have suddenly blocked the built-in keyboard on your laptop, then explore several options for solving this problem:

• One of the most common mistakes that users of laptops with shortened keyboards can make is pressing a combination of two keys: fn and Num Lock. This action turns on the numeric keypad, but turns off the set of other characters, in particular letters. You need to use this combination again so that the keyboard layout switches to the standard mode.
• If the keyboard on the laptop is really completely blocked, then, depending on the model of your laptop, resort to some key combination (this combination should be indicated in the instructions for your laptop): Win+(F1-F12), fn+Pause, fn+F7, fn+F12.
• If you do not have instructions for your laptop, and you cannot find out the key combinations you need to unlock the keyboard, then go to the official website of the company that released your laptop. Download the instructions there, or contact the technical support of the site, indicating the model of the laptop and the nature of the problem.
• When the touchpad (touchpad) on the laptop keyboard is locked, press at the same time fn and F7.
• If you use the key to unlock or lock fn in combination with others, then it will be important for you to pay attention to the characters drawn on these keys. As a rule, these characters are placed in square brackets so that the user can immediately find them on the keyboard. But it is best to use the instructions for using your particular laptop model and its keyboard, since the assignment of the keys may be different for different laptops.

How to permanently disable the keyboard on a laptop

Basically, the keyboard matches the laptop model, which consists of a combination of letters and numbers next to the series and manufacturer's name on the case, in and in the instructions for use. There, in the instructions, you can also find answers to questions about how to turn the keyboard on or off on a laptop, how to get help in primary diagnostics, and other points on working with office equipment. There are exceptions when the model can only be determined using the HP Support Assistant program, located on the official website. One of the modern developments in the field is an upgraded laptop model, which offers a numeric keypad as an alternative to a mobile computer. Sleek and compact "soft" laptop expands the range of user options: if necessary, the keyboard can be removed under the screen and convert the concept into a tablet.

Variety of modern keyboard

In addition to digital, quite a few have been released lately a large number of redesigned keyboards designed for simplicity and ease of use. These include such types of keypads as flexible, with illuminated letters and organizer. A soft keyboard is a special type that is quite common today in the operation of office equipment. First of all, its advantages include, of course, ease of transportation and maintenance. Among other things, it is also a whole collection of 3 in 1, which also performs the functions of an Internet phone and a USB hub. Another great retrofit idea is a backlit keyboard. Today, such devices have a different design, functionality and layout. Over the years, similar models have been used maximum amount users. But there are times when the backlight just gets in the way, and it is turned off. The instructions describe all the steps: how to turn it off and how to turn it on. A keyboard on a backlit laptop is best purchased for those who work at night, in addition to good visibility, working with such keys is also almost silent.

How to turn on the keyboard on a laptop?

In different laptop models, the “on and off” key combinations differ, and are regulated by the BIOS or the manufacturer's proprietary program that is loaded with the system. For beginners who use the digital concept for the first time, there is often a problem and the question that follows from it: “How do I turn on the keyboard on a laptop?” This topic is given sufficient space in the instructions and a step-by-step explanation is given. One of standard options is to use the "Num Lock" key, which is located in the upper left position of the keyboard. But there are models in which the mentioned key is absent, usually this applies to portable computers, in which a separate group of numeric keys is not provided at all. In this case, you should check the functionality of the Fn + F11 key combination; on the keyboard, these buttons usually belong to the main group and are combined with letters. Also, to turn on, instead of "F11", another button of the functional row can be used.

For the case when the right way turning on the keyboard does not help, you should use the third non-standard method - using the on-screen keyboard. This program, which is a standard Windows application, is called on the monitor from the main menu. Having opened it, enter the "All programs" section, in which go to the "Standard" subsection and to the "Accessibility" section, and there already select the "On-Screen Keyboard". It can be activated without using the main menu, but by simultaneously pressing the "Win and r" keys and entering the "osk" command and the "Enter" key, and in the interface that appears, find the "nlk" button and click it with the mouse.

Sometimes a seemingly irreparable problem can occur when the control on a laptop computer simply stops working. The question immediately arises as to why the laptop keyboard does not work. There can be many reasons for this, for example, when you just recently bought a portable device, and after unpacking, you found out that the control does not work. In fact, there is no need to worry, since the issue can be resolved without opening the case. Moreover, if you are a simple user, this is not recommended, otherwise the device may have to be sent to a service center for repair. Today we will give several options with which you can learn how to turn on the keyboard on a laptop. But if this is really a technical malfunction, then none of the methods will help you. We will also talk about how to turn on the numeric keypad on a portable PC, of ​​course, if it is present on your device. Sometimes it may happen that the main part of the control works, but the numeric keypad does not.

Combination

In most cases, the backlight of the keyboard on a laptop does not work due to pressing the keys, precisely those with which the shutdown is performed. In order for the element of interest to us to work again as before, you will need to press the appropriate buttons, but the shutdown can occur without your knowledge. For example, when a child used a computer, and you simply do not have the opportunity to know what he pressed, then you need to know how to turn on the keyboard on a laptop.

Instruction

Let's get straight to the issue. We will immediately give the easiest way by which you can quickly bring the device to working condition. Every laptop has a dedicated Fn button that is used in conjunction with other keys from F1 to F12. You need to look at all these elements, you can notice small images on them. If you find the keyboard icon, that's already very good. To turn it on, you should first press the Fn button along with the key that shows the PC control panel. If your laptop does not support backlighting, then the combination of these keys will be responsible for turning the buttons on and off. As we wrote earlier, not all devices may have a special function to enable or disable control, and accordingly, this method is not always suitable.

And it also happens...

Now let's look at the second solution to the problem. You should pay attention to whether there are drivers for the keyboard. In some cases, system files can be corrupted by antivirus, incorrectly installed, or accidentally deleted with my own hands. Do not worry, as it will not be difficult to solve this problem. Before installing new software packages, you will need to download them. Or you can mount them from disk. If you search for keyboard drivers on the Internet, then we recommend that you immediately visit the official website of the manufacturer of your device, since only there you can find the really necessary kit for it, while it will be updated to the latest version.

BIOS

If the question of how to enable the keyboard on a laptop is still not resolved, then you should look for the corresponding items in the BIOS. Of course, if you are a simple user, you simply won’t be able to configure the parameters yourself, therefore, when other solutions did not help you, you should contact a specialist or technical service. If you need to learn how to switch the keyboard on a laptop, remember that everything will depend on the installed on the device operating system. In Windows 7, you can change the keyboard layout using the keyboard shortcuts Alt + Shift, and for XP this combination will be Ctrl + Shift. If you have a number pad and you should turn it on, then we'll walk you through how to do it.

Calculator

The element of interest to us is located in the same place as on a personal computer, or rather it is right part. This field contains numbers and the most basic symbols. To enable control, you must press the NumLock key, on some laptop models its name may be abbreviated - numlk. This button is located above all numbers. If you notice that the indicator is off, then the function is turned off, and after pressing the inscription should light up, and then the digital part will start working. If there is no such key, but you still need to find out how to turn on the keyboard on the laptop on the right side, then you should try the Fn + F combination. The solution does not always help, so if the issue has not been resolved, then it is advisable to look for the button that answers for the digital part.

If you accidentally locked the built-in device, or the buttons became unresponsive as a result of an error, then in order to troubleshoot the problem, you need to know how to enable the keyboard on a laptop.

Hotkeys

Judging by the forums, most often the spontaneous shutdown of the keyboard occurs after a little cleaning. We wiped the laptop with a cloth - the buttons stopped working. If the rag was not wet, and liquid did not get inside the case, then such a problem can be eliminated quickly enough. Most likely, you accidentally pressed a keyboard shortcut that disables the built-in input device.

On some laptops, to turn the keyboard on / off, use the combination of the Fn function button and one of the keys in the F1-F12 row - for example, Fn + F1. To understand which key you need, take a close look at the icons. Look for a button with a lock, if you press it together with Fn, the keyboard will lock.

If you need to enable only the block with the numbers on the right, press Num Lock or the Fn + Num Lock combination. If these combinations do not help, look for the desired combination in the instructions for the laptop.

Checking Drivers

The operation of the built-in keyboard does not require the installation of special software, but if the input device is not responding, you should look at how it is defined in the device manager:

You can try installing a hotkey utility on your laptop (downloaded from the laptop manufacturer's website). Perhaps the lack of such a utility prevents you from unlocking the buttons using a combination with the Fn key.

Lifting the ban

The keyboard on a laptop can be disabled intentionally. To make sure there is no ban, check the Group Policy Editor:

If you have checked all the software methods, but did not understand how to enable the keyboard on a laptop, then pay attention to physical state laptop.

Hardware failure

If water gets on the keyboard, or the laptop is subjected to mechanical stress, then you should contact the service. But you can try to determine the degree of damage to the laptop yourself. See if the USB ports are working, connector for network cable and touchpad. If these components are also idle, then the cause of the problem is the failure of the south bridge of the motherboard.

If one keyboard does not work, try to disassemble the laptop yourself (provided that the warranty has already expired) and check the cable. Before opening the case, it is recommended that you read the disassembly guide for your model so as not to damage fragile components.

On many laptops, the keyboard rests on latches recessed into the case. You can pry them out with a screwdriver. You should start from the left side. Pry up the edge of the keyboard with a screwdriver, pry the canvas with a needle, or gently pull the Esc key.

Clean the contacts, and then put the cable back in place, securing it securely with the latch. If the keyboard or cable is damaged, you can change them yourself.
