Button lock on on lg TV. The procedure for unlocking the keyboard on a laptop. Childproofed but lost remote control

All gadgets break down sooner or later, and smartphones are no exception. In fact, phones can be extremely fragile - sometimes just dropping them is enough to render them useless or badly damaged. But even if the phone has never been dropped, there are still tons of things that can happen to it. One of them is when, at some point, the screen lock button stops functioning, and then you are simply not able to lock or unlock it.

Obviously, things are not so bad with phones that have a physical back button like the vast majority of Android phones. The Home key can also be used to wake up the phone. Phones that can be unlocked by double tapping the screen are fine too. But phones that lack the latter feature and have capacitive or on-screen navigation buttons become as functional as potatoes once their lock button stops working. However, there are several things that can be done to remedy the situation.

Step 1: unlock your phone

There are several ways to unlock your phone without relying on its power button. You need to have someone call you - in most cases, this will turn on the screen and give you control over the phone. Once the phone is working, you can proceed to the second step. Alternative option: connect your phone to a charger. This will turn on the screen and allow you to access the device. If your phone has a physical camera button, hold it down. This should launch your camera app, which you can simply close and use other phone functions.

NOTE: If the lock button gets stuck, as if it is constantly being pressed down, shake the phone well, just do not bump it on anything. If you are lucky, the button will move away and work normally. Avoid turning off your phone completely, because then you won't be able to turn it back on without a working power button.

Now that the phone is working, you can replace the screen lock button with one of the dedicated apps.

Step 2: Select the application

There are a number of applications that will allow you to remap the lock function from a faulty button. You can easily find any application that best suits your needs. Here are the most popular and effective ones:

1) Power Button to Volume Button.

This app reassigns the lock button to the volume button. It is compatible with the vast majority of Android phones and does not require root rights. The program is absolutely free, so you can always use it.

2) Gravity Unlock.

This application will also be of great help in case of a malfunction of the screen lock button. It automatically detects your hand position and unlocks your phone if you hold it like you want to use it. The program works fine with most phones, although some models may have problems.

3) Shake Screen On Off.

This application will unlock your phone when you shake it well. The program automatically analyzes the situation, preventing accidental and unwanted unlocks, when the phone can be shaken in your bag, for example.

Step 3: find a permanent solution

All of the above, although it will be effective in most cases, is still a temporary solution, not a permanent one. It will be better if you contact the service center if your phone has a faulty screen lock button.

Sometimes it happens that children or adult users inadvertently turn on the lock on the TV, or parents block the TV from their children, and then find it difficult to remove it. Situations are not uncommon when the owner simply forgot the password and now he himself cannot view the channels. Signs of TV blocking are:

Displaying a blue screen with a key;

A field appeared on the screen where the device asks for a PIN code (password);

Only one channel is available for viewing.

Answering the question of how to remove the lock from the TV, it is necessary to highlight three main options for solving this problem, namely:

Disable blocking using the remote control by typing a special combination of buttons;

Configure channels again (sometimes they can be knocked down by accident or due to a software failure);

Flash TV memory.

Usually, the blocking is removed on its own, but if a flashing is required, it is better to resort to the help of a specialist. In general, for independent work, the owner needs only two things - an instruction manual for his TV and a working remote control for it. If the instruction is lost, it will not be difficult to view or download it on the Internet. For TV model, see the rear of the TV.

What to do in a standard situation

Having on hand the instructions for the TV, you should carefully read those sections of it that relate to blocking. Your task is to find a special code, a combination of numbers, after dialing which a lock is put and unlocked on the remote control. Also, the instructions contain the steps and their sequence specifically for your model. If there are no instructions, and there is no access to the network at the moment, you will have to strain your memory and remember what exactly led to the device being blocked.

From the remote control, press the P and + buttons, holding them simultaneously. Next, in the field you need to enter a password of three or four digits. The type of such combinations usually consists of the same values, for example, 1111, 4444, 333, coinciding with the number of the most frequently used channel. Quite often, standard codes in the form of 1234 and others are used. After entering, press + again.

If after these steps you cannot unlock the Akai TV (Akai), Samsung, LG, Thomson models and others, the password is not reliably known, you can try other combinations, they are set by the factory settings, which are not too complicated.

There are TVs that support locking with only one button. Accordingly, to block or unblock channels, you need to hold down this button for five to ten seconds.

Potential problems and what to do about them

Before unlocking the TV, you must first understand the cause of the problem. Based on practice, the most common cases are presented below:

Sometimes it happens that after the blocking is removed, the TV channels are not tuned or after they go astray again, the TV menu hangs, and other strange failures are found. This may indicate that the tuner is defective and the TV needs to be flashed (updated). For inexperienced users, it will be more expedient to contact a specialist.

By default, any smartphone or tablet, after pressing its power button, offers to make a swipe across the screen. Only then will you be taken to the desktop. This is done so that the device does not perform any actions on its own while in your pocket. Google is doing everything to make the lock screen as convenient as possible. But sometimes people still wonder how to disable the screen lock on Android. This can be done very simply.

But first, a little theory. Disabling the screen lock completely can lead to some problems. Google increases the functionality of the screen for a reason, allowing you to go directly from it to taking photos, making a call, and sometimes some other functions. If you don't like the traditional way of unlocking your device, why not try another one?

At the time of this writing, the following types of screen locks are standard for Android:

• Swipe across the screen - the same traditional unlocking method.
• Entering PIN is a very old method and is fairly secure. The simplest selection of the PIN-code does not work here, since after several unsuccessful attempts a timer appears - a new entry will be available only after its expiration.
• Graphic key - ideal for those who are better at remembering visual information rather than a set of numbers.
• Fingerprint is the most reliable way to protect the information contained on your smartphone. It is almost impossible to outwit a fingerprint sensor.
• Iris - its scanning is implemented in Samsung Galaxy S8 and S8 +. In the future, this unlocking method will be implemented in other flagship devices.
• Password input - the longest unlocking method. A password differs from a PIN code in that it can contain letters and other symbols.

Many other lock screens can be found on Google Play. They may use other methods, such as solving a math problem. But this is more of a pampering than a real improvement of the existing system.

Eliminate the lock screen

If you want to remove the lock screen, you will have to delve into the settings. However, you should not be afraid. If you follow our instructions, the whole process will take you just a couple of minutes:

Step 1. Go to « Settings».

Step 2. Go to the section " Safety". Some devices skip this step.

Step 3. Select " Screen lock».

Step 4. Click here " No" or " Is absent».

This way you can turn off the pattern or remove any other type of screen lock. However, do not forget that the system may ask you to enter a password or PIN code, if one has been set. This is done for security purposes - what if you have someone else's smartphone in your hands? Therefore, you cannot remove the password from the lock screen without entering it.

What to do if you forgot your pattern or password?

It's much more complicated if you forgot your password, PIN or pattern. In this case, you will not even be taken to the settings section. Fortunately, the problem can be solved on some devices. After several unsuccessful attempts to enter the key, the graphical screen lock may offer to get to the desktop in a different way - by entering data from your google account .

If Internet access is disabled on your smartphone, then you will have to reset to factory settings using the Recovery mode. In this case, user files from the phone will be deleted, as well as all settings. At the same time, the screen lock will be eliminated - it will return to its previous form when you need to slide your finger across the display.

People who have children in the family or have a cat at home have probably faced such a situation when a fluffy pet fiddles and climbs on the keyboard to warm up. And for some reason children are constantly attracted by these tempting buttons. How can you not get interested when you press the keys, and different "pictures" pop up on the monitor. It's okay if the child just opens a document or application, but what if he deletes some important files? How many worries, nerves and problems can arise because of this? To protect yourself and your computer from unwanted tampering, you should consider a feature such as a keyboard lock.

How do I lock the keyboard using hot keys?

Usually, if an account is installed on the computer, then when it starts a window will appear asking for a password to log in to the system. When working with files, browsing the Internet or performing any other actions, you can always return to this window. To do this, you need to use the Win + L key combination. Of course, in order to return the computer back to working condition, you will have to enter a password, but this method will help not only lock the keyboard, but also hide what is happening on the monitor from prying eyes. Of course, the password should be chosen according to security rules - at least 6 characters so that it cannot be picked by accidental keystrokes. In this case, the child is more likely to pick out the keys than gain access to your files. Locking the keyboard on a laptop while browsing the Internet is possible by switching to full screen mode. To do this, press the Fn + F11 or Fn + key with the image of a lock. You can return to normal mode using the same combination.

Locking the keyboard using special programs

You can lock the keyboard on your computer using special programs. One of them is TodlerKeys. It is convenient in that when you start it, only the keyboard is locked, and you can continue to use the mouse. Installation of this program does not require financial costs, that is, it is completely free. If the need for this program has disappeared, then you can simply turn it off. Another program of this type is TypetoEasy 2.0. It's also completely free. It will take very little time to install these applications. To do this, you need to download the program, find it in the folder with the downloaded files and click on its icon with the mouse. After that, the installation will start, the user just needs to follow the installation instructions. After installing a program, as a rule, you need to restart your computer. In order for the computer keyboard lock to turn on, you must run the program, while the mouse will continue to work. A program called Keyboard Locker also exercises parental control, blocking not only the keyboard, but also the computer mouse.

Additional Information

It should be noted that all these programs, as mentioned above, have one significant plus - they are all completely free. In addition, their installation is simple and does not require any special skills. If, during installation, the application asks to activate a code or send a paid SMS to activate it, then you should not continue the installation. Most likely, this is a virus program used by fraudsters to pull money. It can harm your computer. There is also a way to disable the keyboard until the next system startup. To do this, follow a series of steps: [Start menu - Programs - Accessories]. There will be a command line in which you need to enter the command "rundll32 keyboard, disable" (enter without quotes). After this action, the keyboard lock will start, which will last until the system starts up again.

Being in a pocket of trousers, a cosmetic bag or a bag, involuntary pressing on the keys of the mobile phone can lead to comical, but often undesirable consequences. Mobile phone keypad lock prevents accidental sms, outgoing calls and settings changes.

Instructions

Any mobile phone is equipped with a keypad lock / unlock function. The only exception are phones in the form of "clamshell", which do not require locking the keys, as they are initially protected from accidental unplanned pressing on them. Phones with an open dial pad are subdivided into physical and touch phones.

Typically, to unlock keys from a physical keyboard, you must type a specific combination. This combination is the same as the combination required to lock the keyboard. Often, to unlock, you need to press and hold a specific key, which has a special keyboard lock symbol. Or a combination of two keys performs this function. As a rule, these are the *, # keys and the "Menu" key in various variations.

Touchscreen phones are characterized by the presence of only three keys - "Call acceptance", "Menu", "Call rejection", or the presence of one "Menu" key. These buttons are locked along with the mobile phone screen. In order to unlock the touchscreen phone, a visual key is provided on its screen. Typically, this key has a pattern of a lock symbol (often a "lock"). On some phone models, you must press and hold this key for a few seconds. On others, move the key up. Also, the mobile phone can support both types of unlocking. In this case, in the "Settings" you can choose any of the proposed types, which seems most convenient for you.

Some modern brands of touch screen mobile phones offer their users a more serious and better way to disable phone lock. For this purpose, a certain shape must be drawn on the screen. It could be a zigzag line, for example. This type of unlocking a touchscreen phone is the most reliable, as it excludes accidental pressing.

To avoid accidental calls or changes to the phone settings, be sure to set the keypad lock. Depending on the phone model, the lock is set and unlocked differently.

Instructions

Read the operating instructions of your mobile phone. There must certainly be written how to unlock the buttons. Typically, on phones with physical keyboards, unlocking is done by pressing a certain key combination or by pressing and holding one. It all depends on the phone model and manufacturer. Usually, to lock or unlock the keyboard, use the * and # keys. The "Menu" key is also used. Press these keys in a certain sequence, for example: *, #, "Menu". Then the keyboard will be unlocked.

Follow the steps below to unlock your touchscreen phone. Usually even these phones have several buttons, but they are also locked when the phone is generally locked. To unlock the keyboard, which is actually the screen, you need to press or swipe over a certain part of it. Usually, a picture with a lock is visible on the desired part of the screen. It is precisely this part of it that must be manipulated to unlock the phone.

If there are no instructions for the phone nearby, take a close look at the screen - there should be some prompts with which you will probably understand how to unlock the keyboard. For example, an arrow may be displayed on a panel with a lock.

Swipe in the direction of the arrow - then the keyboard will be unlocked. On some phones, unlocking requires a more complex figure, which, by the way, you can choose yourself.

Draw a broken line of a predetermined shape on the screen of your touchscreen phone. This method of locking the touch screen is considered the most reliable. It protects against unwanted clicks and unwanted intrusions from another person.

Useful advice

Set the option in the "Settings" of your mobile phone, thanks to which the keyboard will be blocked from accidentally pressing keys in a few seconds / minutes after you stop pressing them.
