How to turn off the light on the keyboard. How to disconnect the keyboard backlight on MacBook Pro or AIR. Using a special button

Currently, the keyboard does not only perform its functional role, but also stylistic, emphasizing the individuality of each user. One of the most popular ways to highlight the style specific device - Provide bright and unusual backlight. Its presence provides not only individual style, but also has practical value. It allows you to provide comfortable use This gadget is even in the dark. However, in some cases, it may be irritating, especially in situations, if the light turns off with the computer turn off automatically. Tell how you can do it yourself.

Disconnection in keyboard settings

Using a special button

Often, especially on premium devices, there are special buttons that are responsible for refill control. Usually they are located on top or side on the gadget housing. These buttons are responsible not only for switching on or off the backlight itself, but also for its brightness or color gamut, as well as the radiation intensity (on some models).

Using a special application

For many devices exist special applications, which allow you to perform brightness settings and color Gamma.. They also allow you to set sensitivity and reassign keys on the keyboard.

Disable key combination

In that case, if you need to turn off the backlight on the laptop keyboard, a special key combination will come to the rescue. Usually this combination depends on specific model and lies in keystroke Fn + one of the function buttons (F1 - F12).

Usually the exact combination is indicated in technical documentation For each specific model. If there is no option to open a special documentation, the user can try to find the desired combination by selecting. To do this, press the Fn + button alternately with F1 via F12.

ATTENTION! During such a selection, the laptop can go into sleep or reboot.

Possible problems

There are situations when the backlight continues after turning off the PC. This can cause some inconvenience. This problem is associated with the fact that the USB port, even after the disconnection, is given a rated voltage, which is why the keyboard remains in operation. You can fix it in several ways:

• Disable the device. To do this, it is enough to pull the USB wire from the connector. This method Not very convenient, as it requires a constant connection and disconnection of the gadget.
• Disconnection through bios. To do this, go to the BIOS settings. To do this, you need to press the DEL or F2 button while turning on the computer. In the menu that opens, go to the Power Management section and select ERP Disabled.

REFERENCE! IN different versions This item may be called differently.

• Turning off with a hardware way. Usually on the keyboards with backlight on the case there are special controls that allow you to disable or enable the glow. Just press one button, and the problem will be solved.

When there is a categorical need to poke the Surface battery, then the first thing should be turned off the backlight of the tablet keyboard.

Surface Pro, as you know, are equipped with a special sensor that automatically activates the backlight of the "Valentine" physical keyboard keys in conditions of insufficient external lighting.

The feature not only looks pretty, but is also very comfortable and practical. True, not always.

Of course, there is nothing to do the reverse side of such quite significant, as for mobile devices, luxury. In the desktop mode, that is, when the tablet is connected to the outlet, it can illuminate its keyboard as much as you like. However, when working from battery, the backlight begins to spend its charge very noticeable, which is sometimes completely inappropriate.

On the Linus Tech Tips site, letter managed to familiarize himself with the results of the Surface Pro battery test results. So, experiments show that if you turn off the backlight of the tablet keyboard, then its autonomy (battery life) increases by 16%.

By the way, we simultaneously note that, as the same tests showed, the autonomy of Surface Pro also increases:

• by 20-30%, if you turn off the mouse and keyboard at all;
• by 16%, if the screen brightness level is 50%.

So, how to turn off the keyboard backlight tablet Surface. Pro.

As we have already told, the Surface Pro illumination of the keyboard turns on-turns off automatically by a special built-in sensor. In the new keyboards, it is also possible to shut down the backlight manually, but only in new ones. In the old manually, turn off the backlight will simply fail. But there are nuances.

In fact, the backlight in Surface Pro can control the F1 and F2 keys (the first two keyboard buttons next to the ESC key). If you just click on any of them, nothing happens, including backlit. It is quite another thing if you use the ALT + F1 and ALT + F2 keys combinations.

Click and get the desired:

• Alt + F1 - the brightness of the backlight of the keyboard increases;
• Alt + F2 - the brightness of the backlight of the keyboard decreases (up to a complete shutdown).

In general, such a focus. It helps how to quickly configure the brightness of the backlight of the buttons, and turn off the backlight at all if the tablet is very much needed, and it is still far from the outlet.

One of the laptop ergonomics indicators is the backlight of its keyboard. This feature Significantly simplifies work with the device both at night and the day with an insufficient level of illumination. But some users forget about the presence of such a useful option or simply do not know how to use it.

How to turn on the keyboard backlight on laptops from different manufacturers? In search of an answer, consider all possible options.

Enable keyboard backlight

Before trying to activate the keyboard backlight, it is necessary to know exactly that such a function is present on your laptop model. And if you look specifications And you have no desire to re-read the user's manual, you should carefully look at the special characters applied to the F1 - F12 function keys. As a rule, the keyboard illumination icon looks so icon and is located on the F4 button.

After discovering the desired symbol, it is necessary to simultaneously press the combination of Fn + F4. In the same moment, all keys on the keyboard will start glowing. If pressing on Fn + F4 did not give a positive result, you can look for the backlight alternately by pressing Fn and other functional buttons. It should be borne in mind that during a random search of the desired combination, other functions will be activated, the operation of which can be turned off by repeatedly pressing the previous combination.

In some models, the keyboard highlight option is fixed behind the combination of the Fn + Space keys, for example, in the Lenovo Z500 model. Or is made in the form of a separate button located above the keyboard (MSI GE60, MSI GE70).
In addition, in many modern laptops, you can not only turn on and off the backlight, but also to control the brightness of the luminosity of LEDs. For example, ASUS Series FX gives the user the ability to choose one of the three brightness modes. Here, the increase in brightness is carried out by combining the press on the Fn + F4 keys, and the decrease in the Fn + F3 keys. In this case, the plate appears on the screen indicating the current brightness level.
Unfortunately, users do not always manage to turn on the backlight of the buttons in the standard way. Especially often such a problem occurs after reinstalling the OS, as a result of which the laptop lacks the corresponding driver. To solve the problem, you need to find the backlight driver on the official website, download it and install on your portable computer.

Shutdown

When the need for backlight disappears, it can be turned off. But, as well as with the inclusion, the unified standard shutdown button does not exist. In all models, this feature is implemented in different ways, for example:

• disconnection is made by the same combination of buttons as the inclusion (Fn + F4, Fn + Space);
• to disable, the function button is used, located next to the power button;
• the backlight turns off into several steps when repeatedly press Fn and the function key with the keyboard icon.

How to change the color of the keyboard backlight?

To date, most laptop manufacturers collect keyboard backlight on monochrome LEDs, as a result of which the user cannot change its color. However, there are also such models in which the backlight is collected on RGB LEDs. For example, ASUS uses multicolor LEDs in its new laptops, which can be controlled using the ASUS AURA patented. Owners of such devices may on their discretion change color and brightness LED indicatorspicking up a nice eye background.

In addition to ASUS AURA, there is a universal Steel Series Engine program, which is compatible with all laptop models. With it, you can set the color of the luminosity of LEDs, as well as use other features of the multifunction menu.

If a single-color backlight is installed on a computer keyboard, which does not help, and vice versa, irritates his eyes, it can be finalized by one of two ways. In the first case, you need to disassemble the keyboard, dismantle the backlight board and determine the type of LEDs installed on it. After that, they can be replaced by LEDs of the same size, but the other color of the glow.

The second option involves to disassemble the keyboard and the backlight board paste stickers from translucent paper (yellow, green, blue). After assembling the keys will appear orange, azure and purple light, which will be forced to pass through a paper light filter.

For a laptop, which has never been to highlight, you can make your own hand-made miniature USB lamp on bright LEDs. Or buy a ready-made USB LED backlight for the keyboard via the Internet.

The switch with LED or neon backlight is no longer uncommon in homes. The use of such switches is quite practical. At night, you do not have to look for the wall with your hand to grope the switch. With the appearance of LED and CLL lamps began to occur big problems. In particular, most modern LED lamps are blinking when the switch is turned off. Today we'll figure it out how to turn off the backlight on the switch.

This effect occurs due to a closed electrical circuit formed by a resistor with a LED (or neon lamp) and a LED power converter circuit and a lamp. In this article, we will consider the simplest method on the question: how to turn off the backlight in the switch.

How to turn off the backlight on the switch: 1 stage

How to turn off the backlight on the switch

1 of 2.

Disconnect the part where the LED

Disassembled switch with LED inside

Initially, we need to dismantle the switch. Turn off from conductors, pre-disconnecting the switch from electricity. For those who have repeatedly did it - the class "Pleum".

After the switch is dismantled, it is necessary to remove the casing, where the LED itself (or neon) is located.

In our case, the backlight consists of an neon lamp and a resistor 150k. With the LED, nothing dramatically changes, so the principle: how to turn off the backlight in the switch with the LED remains similar. The neon lamp is connected via the resistor to the switch terminals.

Connection circuit with backlit switch

If you quickly pop up the backlight connection circuit in the switch? It will look like this:

How to turn off the backlight on the switch: step 2

To correct the situation with, we need to replace the resistor. In our case, we take a resistor on 220 com and diode 1 N 4007. Diode can be removed from energy saving lampwhere it is used as a diode bridge. The diagram of the converted switch will look like this:

If we leave a neon lamp, then there will be a resistor at 220 kΩ. If we want to change the indicator on a 3 mm diode, then select a resistor on 680 com. This is guaranteed to save you from the blinking of a diode lamp in the chandelier.

How to turn off the video switch backlight

Well, on the last, look at the video, how to turn off the backlight LED or neon from the switch so that the lamps are not blinking. This is a cardinal solution to the problem. We just whistle all radio leaves and more "do not bathe." However, such a way to combat flashing me does not satisfy me, so it is better to use the above example. And the switch does not need to turn into a simple key and the functions remain.

How to turn off the keyboard backlight?

Master's answer:

The backlight of the phone keypad is not always needed, but it is very often a battery. This feature can be very easy to disable.

To do this, go to the phone menu, in any menu, probably associated with the function you want. These can be the display brightness settings or other settings that can, anyway, affect the operation of the battery.

IN smartphone Nokia. On the Symbian platform, you must enter the control panel in the main menu, and then in the setting of common parameters. As a rule, this is the first item. In the menu style configuration, you must disable the flashing of the light indicator when receiving messages or missed calls. After that, using the Light Sensor menu, set the screen brightness.

Most new phones have a power saving mode. You can enter it using the power button menu.

IN sAMSUNG smartphone The backlight of the keyboard is turned off: in the configuration parameters, the menu item is selected, which is responsible for settings. external view, there you need to turn off the backlight mode.

In many phones, there is no keyboard backlight settings menu or this parameter can be hidden so far that in order to find it, you will have to read the instructions for your mobile device. However, it will not be superfluous for experienced users.

Set the keyboard backlight options in the settings of a specific mode in your phone. This action will be relevant for several models of smartphones.

It is not superfluous to configure the timer to use the keyboard backlight.
