How to unlock the keyboard on a Sony laptop

Unlocking the keyboard. Switching on, configuring and disconnecting the laptop keyboard

Locked on a laptop keyboard is a real problem. The laptop does not respond at all to key presses or responds randomly to certain characters or numbers. Locked keyboard makes it impossible to use the device. You can’t type the address in the browser, reply to the e-mail, or type text in a text editor.

It is necessary to check whether the corresponding lights on the keyboard are lit. Very often users accidentally press these keys, with absolutely no intention of switching to another keyboard mode. For example, the Num Lock key on your notebook keyboard rearranges some of the letter keys and replaces the “U”, “I”, “O” keys with “4”, “5”, “6”, the “J”, “K”, “L” keys with “1”, “2”, “3” and so on in a similar way.

Check if the keyboard works properly. Special settings affected keyboard performance and may have caused the keyboard to feel locked.

You can try to get the keyboard working properly by removing the laptop’s battery. Close all running programs on the laptop. Since the keyboard is locked, use a mouse or touchpad to perform this task. Then turn your notebook off and close it. You can now disconnect the AC adapter (if it was connected) and turn the laptop over to remove the battery. If necessary, you can see how to do this in the laptop manual. After two or three minutes, you can reinsert the battery by placing it back into the battery compartment. Next, power on the laptop and check the keyboard.

Unlocking the touchpad is easier. You often need to lock and unlock the touchpad while working. This is due to the fact that when typing on a “cramped” laptop keyboard it is easy to snag the touchpad, and this leads to unplanned changes in the text. As a rule, you can lock and unlock the touchpad by pressing Fn F6 (Fn F7, Fn F12, Fn F9 or similar). The number of the function key pressed with the Fn key differs for different models. Consult your notebook manual for information about the keyboard shortcut you need. But if there is no manual at hand, the necessary variant is chosen by trying on various similar keyboard shortcuts. On some laptops keyboards there is a special button that turns off or turns on the touchpad, it can depict a crossed square. Unlocking the touchpad is easier.

What can cause a lockout

Depending on the cause of the keyboard lock on your device, you will need to determine your next steps and a suitable way to implement them. Here are the main reasons for locking the keyboard:

  • It was blocked by you or another user. It could be accidental or deliberate. As a rule, many laptops have the ability to lock the keyboard with a combination of “hot” keys;
  • Hardware failure. Here already more difficult, as there is a chance that the keyboard will have to be completely replaced;
  • System failure. The keyboard on your notebook can be blocked because of a system malfunction. To unlock it, you may need a certain number of actions, which depends on the complexity of the failure;
  • Virus infection. First you have to remove the virus software that is located on your laptop. If after that the keyboard does not work, then you have to look for something else affected by the virus activity.

Let’s move on to the ways to solve the problem.

“Hot” keys

This option is appropriate in cases where you/the other user accidentally or intentionally locks the keyboard using keyboard shortcuts. Also, do not forget that the laptop and Windows can give system failures, which can lead to a locked keyboard, although this happens very rarely. If it still happens, in most cases you can use the following keyboard shortcuts to help.

Let’s move on to the available keyboard shortcuts:

The keyboard shortcuts discussed are suitable for laptops from any manufacturer, be it Lenovo, Asus, Samsung, Toshiba, Dexp, Dell, HP, etc.д. The only exception may be very old laptops, which have long been out of stock. With these models it is usually not possible to lock the keyboard or it is locked using a separate button on the chassis.

Hardware problem solution

You do not need to use keyboard shortcuts to deactivate the keyboard on Windows laptops. It can be deactivated by standard means of the system. Also, sometimes there are various failures in the system that can cause deactivation of the keyboard.

The solution to this problem is found in the following instruction:

This method is fully universal for all notebooks and operating systems starting from Windows Vista.

Blocker programs

It may be that your laptop was somehow installed on a blocker program, which blocks under certain conditions the keyboard. Unfortunately, if this happens, it will be very difficult to bypass these programs and you will have to use an external plug-in keyboard, and then search for a program that blocks the main keyboard.

But in this case, too, many difficulties may arise, since such programs run in the background and try to mask their data as much as possible, which makes it difficult to find them.

True, some programs have special hotkeys that can immediately unlock or call the interface of this program. Try these combinations:

These programs are not always viruses, but they occur very rarely. As a rule, they may have been installed by another user who does not want the computer to be used by anyone other than him. True, in such cases they usually set a password on the operating system.

Activities of viruses

There are viruses that can block the keyboard and other controls on laptops. In such cases you need to search for them with antivirus software and then remove them. However, virus removal can not guarantee that immediately after that the keyboard will work, you may additionally need to use other methods presented in the article.

You can scan your computer with standard Windows Defender but this is only if you do not have any commercial antivirus installed on your computer. If it is installed, it is best to check through it. Since there are many antivirus solutions on the market, it is impossible to give universal instructions for each, so let’s consider everything using Windows Defender as an example:

If after deleting viruses the keyboard is still not unlocked, then review and perform other variants of the problem presented in this article.

Cleaning the system from debris

If your system is too clogged up with trash files it can crash on a regular basis and work slowly. Fortunately, this problem can be solved by cleaning your system and registry with special programs. By itself to climb into the registry or into the system sections is not recommended, especially if you do not understand what you’re doing, as you can only make things worse.

Let’s look at the cleaning process on the example of the program CCleaner. First, you need to remove all the system garbage:

As you can see, there is nothing complicated about turning on a locked keyboard on a laptop from any manufacturer, be it Lenovo, Samsung, Asus, Acer, etc.д. You may have to use several options for solving the problem at once, which were described in this article.

One of the most important accessories for the PC user. keyboard. It is with it that you can enter the information you need in the computer. Nowadays, some of the most popular keyboards are Logitech. They are characterized by good design and reliability. But very often you’ve spilled liquids on your keyboard. To clean it, you need to disassemble it.

Disconnecting the keyboard for later replacement

We will consider the ways of disconnecting the keyboard specifically for its manual replacement, as it is a more complicated operation than just disconnecting.

Disable keyboard in Windows

First we need to disable the keyboard in the system and make the laptop forget it. This method is suitable for Windows 7 only. For other versions you will need to install the group policy editor gpedit.msc. It is easy enough to find it on the internet, so let’s not dwell on it.

To lock the keyboard indefinitely:

  • Go to “Control Panel
  • Find “Device Manager”
  • There, find the “Keyboards”
  • Select “Standard keyboard”
  • Right-click on “Properties.”
  • Open “Information
  • Find “Hardware ID” and copy the value.
  • Local Computer” policy
  • Computer Configuration
  • Go to “Administrative Templates”
  • Go to “System.”
  • Let’s click on “Device Installation”
  • Select “Device Installation Restrictions”
  • In the item “Prevent the installation of devices with the specified device codes” right-click and select “Change.
  • Switching to “Enable”.
  • Press the button “Show” and in the window that will pop up, paste the previously copied “ID of the onboard keyboard”, then press OK.
  • Check “also apply to devices that have already been installed.”and OK.
  • In the Device Manager remove the old and no longer needed keyboard.

Reboot and enjoy the work done. Already without keyboard.

Physically disconnecting the keyboard

Notebook keyboard is usually connected to the motherboard by cords. And if you decide to disconnect it at this level, then be prepared to disassemble the “laptop”. Each device has a different architecture and therefore the keyboard stub will be in a different place.

First you need to remove the back cover. Carefully examine and try to identify this loop. If you can not find it, then download on the Internet or on the official website of the manufacturer schematic.

Work carefully, as even minor damage or a scratch on the motherboard can damage the functionality of the laptop as a whole.

As you will have to plug it back in later on, it is a good idea to memorize the location of the connector. For convenience you can take a picture on your phone or digital camera. If successfully disconnected, do not forget to reassemble the laptop in the reverse order. It is desirable to entrust such work to a specialist of the service center.

The article describes how to unlock the laptop and the laptop keyboard.

Some users sometimes locks and disables the keyboard on the laptop, which for a beginner can be a bit of a problem. The keyboard of your notebook may lock, for example, if you accidentally press any combination of keys. Usually this combination of Win and some other key (combinations may vary for individual laptop models).

In this review we will talk about how to remove/set the lock on the laptop keyboard.

Minor malfunctions of notebook keyboards

If you usually work on a battery, the keyboard may not work when the battery is low. What to do. Take out the battery. plug it in, insert the battery. charge it fully and continue to work like nothing happened.

Sometimes you just need to clean the keys on your laptop. I will tell you how to do it using a funny example. I once used a fly swatter to kill a fly on my Asus laptop keyboard, 8 keys popped out of their sockets, absolutely intact. I cleaned the keyboard and put the buttons back where they belong.

You certainly do not do so, and if you need to clean the buttons, it is best to use a special air can. Then remove the buttons do not have to. it costs about 10 dollars.

In most cases, the button does not work because of a spill of tea or coffee on it. Reanimate it after that you can. As soon as possible remove the battery, disassemble, wipe and dry.

I want to tell or remind that all components of a laptop including a keyboard are displayed in the Device Manager (it is possible to look at serviceability). See if you can find the cause there.
