How to turn on the top keyboard on a laptop. Additional keys on a laptop

Instructions

Press the key labeled Num Lock to enable the numeric keyboard... It is located, as a rule, just on this very additional numeric keypad and stands in the very first (left) place in the top row. It works as a trigger, that is, when the side section of the keyboard is off, pressing this button turns it on, and when it is on, it turns it off.

Use the fn + f11 keyboard shortcut to enable this additional numeric keyboard on a laptop or laptop. On some of the models of such computers, to reduce the size, the additional keyboard is removed, and its functions are transferred to a group of keys on the main keyboard. These buttons have additional designations that differ in color from the designations of the main keys. Pressing fn + f11 reassigns the functions of these keys, and they work just like the number pad on a standard keyboard. The f11 key may be replaced by a different function key, depending on the computer model you are using.

Change the value of the corresponding setting in the BIOS if the additional keyboard turns out to be inactive immediately after boot operating system... Not all BIOS versions have this option, but if it is in your computer, it can be called, for example, Num Lock Status, and the value corresponding to the enabled state is indicated by the inscription ON. To enter the panel BIOS settings, initiate the OS reboot through the main menu on the "Start" button, wait for the computer to shut down and start a new boot cycle. When the lights on the keyboard blink, press the Delete key and you will see the BIOS settings panel. Sometimes, instead of Delete, you need to press f10, f2, f1 or keyboard shortcuts, which can be found in the description of your version.

Problem correct work the additional keyboard is quite common on nix platforms. Users faced with such a task sometimes drive themselves into a dead end, sinning on "curvature" latest version distribution kit, although the solution to the problem lies on the surface.

You will need

Operating system of the Linux family.

Instructions

The most susceptible to this disease are fresh distributions (alpha and beta versions), mainly Debian-based systems, namely: Ubuntu and Linux Mint... First of all, you need to find out the reason for disabling the additional keyboard, because she could not do it without permission.

Test the operation of the NumLock keyboard buttons in different applications, games, as well as the console (standard and virtual). Pay attention to its use in games, you need to assign actions to the buttons used (from 1 to 9). Do not be afraid to assign all buttons, the setting can always be returned to its original form.

With a working NumLock, the keys should function in applications such as "Standard Calculator", Gedit and Internet browsers (programs that work with this type of keyboard directly). To launch the virtual console, use the keyboard shortcut Ctrl + Alt + T, and for the usual Ctrl + Alt + F1 (F1-F6).

If the problem persists in all of the programs listed above and there is a chance that the keyboard might not work, then you have activated the Mouse Pointer Control from the Keyboard feature. To cure this disease is simple, just press the Ctrl + Shift + NumLock key combination again.

To avoid subsequent attempts accidental pressing these keys, you need to go to the "System" menu and select the "Keyboard" item from the "Parameters" list. In the window that opens, go to the "Mouse buttons" tab, uncheck the item "Allow the pointer to be controlled from the keyboard." Now this problem will no longer disturb you.

In some cases, you may need to reboot the system or just restart the "x" (x-server). To do this, press the key combination Ctrl + Alt + Backspace.

Side panel on the computer monitor can be a good helper in obtaining the necessary information. It contains gadgets such as Weather, Currency Rates, Clock, Slide Show, and others. For example, by placing the Weather widget on the side panel and by adjusting it to your region, you will always be aware of what the weather is expected today, as well as for the coming days. The same goes for exchange rates and other information.

You will need

- a computer;
- side panel.

Instructions

Side panel you can customize on top of all windows, remove or add gadgets, select the clock format, and so on. When the sidebar is not needed or interferes with working with documents, it is easy to disable it.

To disable the side panel, click on it right click mice. In the window that opens, select "Close side panel". It will disappear from the desktop. At the same time, those gadgets that you have placed on the desktop will still be displayed. Side panel It is also easy to reopen it by right-clicking its icon on the taskbar in the notification area, which is located in the lower right corner.

If the side panel you do not need it, you can exit it by closing all widgets and removing the sidebar icon from the notification area on the taskbar. To do this, in the notification area, right-click on the sidebar icon. In the window that opens, select "Exit". Side panel will be closed, and with it all applications that you installed on your desktop.

In case it is necessary to return the side panel on your computer desktop, go to the Start menu and All Programs. Next, find the item "Side panel"Or Windows Sidebar. Launch this program with one click of the mouse. Now open your desktop and check for the utility. It is also worth noting that this program resumes its work when you restart your computer, so you can simply restart your PC and everything will fall into place.

In general, we can say that turning off the side panel on a computer is not difficult, as well as turning it on, the main thing is to perform all the actions in order. After several times, you will not have such difficulties when working with a personal computer or laptop.

How To Enable An Additional Keyboard - Printable Version Rate this article!

Most laptops have a full-size keyboard with a numeric keypad on the right. But to use these buttons, you must first turn on the side unit. This can be done using the Num Lock key or a combination with the Fn button, through the on-screen keyboard or in the BIOS settings.

Using hotkeys

To turn on the numbers on the right (this block is also called the Numpad), find and press the Num Lock button. On the external input device, when this button is pressed, the indicator lights up, under which a number is drawn. On the laptop, no indicator will light up, but the digital block should work.

If there is no Num Lock key on the laptop, enable Numpad with function key Fn. Look at the row of keys F1-F12: the images should indicate which combination is used to activate the number pad on the right. Turn on frequently right keyboard with numbers allows the combination of Fn + F11, but there may be other options.

Some laptops use the Fn + Alt combination - for example, this is how Numpad is turned on on Sony laptops. In order not to go through all the available combinations with the Fn button, see the desired combination in the instructions that came in the box with the laptop. If you have lost your paper manual long ago, download it electronic version on the manufacturer's website or look at the support forum.

Using the onscreen keyboard

If there is no Num Lock key on the laptop, and you cannot turn on the Numpad with numbers using a combination of FN and another button, then try using the on-screen keyboard to activate the block. It is a dedicated system tool that completely replaces the physical input device when it is missing.

A panel with keys will appear on the screen, which completely repeats the view of the physical input device. Numpad on the on-screen keyboard should also be; if there is no block with numbers, open the parameters and mark the item that responds to the activation of the Numpad.

A virtual Num Lock button should appear next to the numbers, after clicking on which the block on the right will work. You can enter numbers as with on-screen keyboard using a mouse or from a physical device. To turn off the block with numbers, click again in virtual keyboard by the Num Lock button.

BIOS setup

In the most difficult cases, enabling the numbers on the keyboard to the right will not work without changing the BIOS settings. Fortunately, this requirement is not so common, but it is better to be aware of this possibility.

The hardest part of this procedure is getting into the BIOS. Most modern laptops implement quick start, so you may simply not have time to press the desired key. This can be fixed by temporarily disabling Fast Startup.

Then to enable the Num Pad, use the NumLock key, which is located in the upper right corner. Usually, when the operating mode is activated, the corresponding LED lights up, if any.

If you need to enable a removable numeric keypad that works over USB, plug it into the corresponding port on motherboard computer or laptop. Install the device driver, if available. If not, use the Add New Hardware Wizard in Computer Control Panel.

Search for new devices connected to your computer. Find your NumPad keyboard in the list, select the driver installation from the Internet, allow the wizard to connect to the network and complete the installation software... Please note that not all keyboards require driver installation for correct operation, sometimes a simple inclusion is enough. Everything here may depend on the model of the computer and the installed operating system, as well as on the type of the input device itself.

Turn on the device by pressing the corresponding button on the case, if there is one. If not, then just press NumLock.

If you want to enable the Num Pad to work on a short keyboard, please make sure it is supported. Usually, in this case, numbers are also written on the keys on the right next to the letters. This mode is started by simultaneously pressing Fn + NumLk. In this case, the corresponding icon should appear on the monitor screen.

If none of the above helps, contact service center as it is possible that your keyboard is damaged. First, check the correctness of the connection of the wires and their safety.

From year to year LEDs are increasingly used, they are beginning to be actively used as sources of illumination. If it becomes necessary to independently connect the LED, certain rules should be followed when performing this work.

You will need

- multimeter (tester);
- power supply;

Instructions

To connect an LED, you need to know its characteristics. Usually LEDs are rated for 20mA current, the nominal voltage depends on the color of the light. For red and yellow LEDs, this is 2 V (1.8 - 2.4 V allowable range). For white, green and blue 3 V (3 - 3.5 V). When connecting the LED, it is important to accurately set the current consumption - 20 mA. In this case, the LED will work properly for many years.

Before connecting the LED, the power supply should be selected. So, if for white, green and blue LEDs two series-connected finger-type batteries of 1.5 V give a total of 3 V, then the required supply voltage should not exceed the maximum value of 3.5 V. But if you turn on red or yellow with two batteries LED, it may just burn out. That is why take a responsible approach to the choice of a power source, make sure that the voltage on the LED does not exceed the permissible value.

If the voltage exceeds the required one, a damping resistor should be included in the circuit. For example, you want to connect a 2 V LED to a 9 V power supply. It turns out an extra 7 V. To extinguish them, using the formula R = U / I, you can determine that the required resistance is 7 V / 0.02 A, or 350 ohms ...

Heat is generated on the damping resistor, so it must have required power... Calculate it using the formula P = U * I. We substitute the data: 7 V * 0.02 A = 0.14 W. This means that you need a resistor of about 0.2 W - it is better to take with some margin.

When using an LED, it is important in practice to select a current no higher than 20 mA. To do this, turn on the tester in the open circuit and check the current strength. If it is slightly less than 20 mA - for example, 17-18, then leave it that way. The LED will shine a little less brightly, but it will work for a very long time. If the current is much lower or higher, you should adjust it by changing the resistance of the additional resistor.

Pay attention to the polarity of the LED connection, incorrect connection may damage it. The anode is connected to the plus of the power supply, the cathode to the minus. A flat area (cut) is made on the side of the cathode on the LED bulb. In addition, the cathode has a shorter lead.

If you want to power an LED or a string of LEDs from the AC mains, then take care of voltage rectification. In the simplest case, a diode with a breakdown voltage of at least 400 V can be included in the circuit.

Instructions

The standard way to turn the numeric keypad on and off is to press the Num Lock key. Find it among the buttons in the upper-right corner of the keyboard - the exact placement may vary on different models of this input device. The enabled state of the numeric keys is signaled by the LED, which should be marked with the same Num Lock designation. If it is off, press NumLock and the numeric keypad will turn on.

Additional keys on a laptop.

If you look closely at the laptop keys, you will notice that some of them, in addition to the usual letters, numbers and symbols, have icons that many do not understand. Usually these icons are made in a different color from the basic symbols on the keys. In addition, a laptop usually has a separate key, which is marked with two symbols - "Fn", these symbols can also be in a frame. The "Fn" key and the icons that I will talk about today in this article are usually painted the same color. As you probably guessed by now, these buttons are related to each other.

By itself, the "Fn" button is called functional, which means that it activates additional functions of the laptop. The combination "Fn", respectively, is an abbreviation for the word Function and reads "Funkshin". Pressing this button in combination with the keys on which there are additional icons (in my case, blue) activates the functions, the meaning of which corresponds to the symbol shown.

Further in the article I will tell you in detail what kind of additional function this or that symbol implies. Since on different laptop models, functional symbols can be on different keys, we will consider additional functions based on them, because they do not differ much from each other on different laptop models.

which are designed as additional functions, help users to quickly perform operations, for example, when it is necessary to mute or mute the sound.

The "Fn" key on a laptop looks like this:

Pressing "Fn" and

Puts the computer into "sleep" mode or returns it to an operational state from "sleep".

Pressing "Fn" and Enable / Disable network adapter wireless network wi-fi laptop.

Pressing "Fn" and Decrease the brightness on the monitor.

Pressing "Fn" and Increase the brightness on the monitor.

For a laptop, this function can be especially relevant, since when the brightness is lowered, power consumption is significantly reduced, that is, in order to increase the battery life, you can sacrifice a little display brightness.

Pressing "Fn" and Turns off / on the screen backlight lamp (s). On some models, it also stretches the image to full screen when working in low resolution.

Pressing "Fn" and Changes the display mode. Useful when using an external display, that is, if an additional monitor / projector is connected to your laptop. The modes are as follows: simultaneously on the laptop display and an external display, or only on one of them.

Pressing "Fn" and Disable / enable the touchpad (touchpad) - a touch pad used as a replacement for a mouse in a laptop. On some models, a separate dedicated button can perform the same function, usually near the touchpad itself.

Below is a photo of the touchpad. Pressing "Fn" and

Turn off the volume.

Pressing "Fn" and

Pressing "Fn" and

Pressing "Fn" and Toggle on / off keypad mode, usually indicating that this mode on, reports one of the LEDs - an indicator on the laptop panel. The question arises: "What can be turned on if there is no such addition on the laptop keyboard?" But, looking more closely, we see that on some keys in blue, there are not pictures, but numbers from 0 to 9, a dash and an asterisk, which exactly correspond to the symbols of the small digit of the keyboard. It should be noted that in some models, if the size permits, there may be a classic small numeric keypad, located on the right, on its separate buttons. In this case, to use it, it is enough to turn on the NumPad mode (NumLk) and just press the keys.

Pressing "Fn" and Turn on / off screen movement mode. Today this function is not widely used and in different applications the result of enabling this mode may be different. In the MSExcel program, you can see the classic sense of using this mode. When ScrollLock is off, the cursor keys (arrows) will move the cursor along the grid of the table, and when ScrollLock is on, the screen will move, while the cursor remains in the same cell.

Pressing "Fn" and Digit 7 when the NumLk mode is on.

Pressing "Fn" and Digit 8 when the NumLk mode is on.

Pressing "Fn" andDigit 9 when the NumLk mode is on.

Pressing "Fn" and the "/" symbol when the NumLk mode is on.

Pressing "Fn" andDigit 4 when the NumLk mode is on.

Pressing "Fn" and Digit 5 when the NumLk mode is on.

Pressing "Fn" and Digit 6 when the NumLk mode is on.

Pressing "Fn" and the Symbol "*" when the NumLk mode is on.

Pressing "Fn" and Digit 1 when the NumLk mode is on.

Pressing "Fn" andDigit 2 when the NumLk mode is on.

Pressing "Fn" and Digit 3 when the NumLk mode is on.

Pressing "Fn" and the Symbol "-" when the NumLk mode is on.

Pressing "Fn" andDigit 0 when the NumLk mode is on.

Pressing "Fn" and the "dot" symbol when the NumLk mode is on.

Pressing "Fn" and the "+" sign when the NumLk mode is on.

Pressing "Fn" and one of the following buttons:

Manages your music player... By default, this group of buttons controls tracks in Windows program Media Player, but if desired, they can be reconfigured to another player, for example Winamp.

Pressing "Fn" and Turns on / off the webcam.

Pressing "Fn" and Turns the "Splendid Video Intelligent Technology" function on and off. This technology enhances the laptop screen display (OSD) by offering a variety of mode options tailored to the specific operating environment. You can see the current mode on the screen (OSD).

You should understand that there may be other icons on the keyboard, and also similar to those discussed above in one of the keyboard. They differ because keyboards are made by different manufacturers.

Now let's tell you what icons you can still find.

Pressing "Fn" and Performs the function of the Home key, that is, moves the cursor to the beginning of a document, web page or folder, depending on which program you are working in.

Pressing "Fn" and will perform the action similar to the previous key, only moves the cursor to the end.

Pressing "Fn" and Calls up the help window.

Pressing "Fn" and Calls up the power settings dialog box.

Pressing "Fn" and Turns on / off the BlueTooth function.

Pressing "Fn" and Activates receiving mail in your mail client (program for receiving Internet mail). To use this function mail program should be configured accordingly.

Pressing "Fn" and Connects the computer to the Internet. To use this function, the computer must have special programs that come with the laptop, if it has such a key.

Pressing "Fn" and

The Pause / Break keys are almost never used. They are designed to suspend a process on a computer.

Pressing "Fn" and Zoom in / out the image.

Pressing "Fn" and Decrease / increase brightness on the monitor.

Pressing "Fn" and

Decrease / increase volume.

Pressing "Fn" and Page Up / Down.

If your laptop has buttons with symbols for additional functions that were not mentioned in the article, then please write about this in the comments to the article.
