How to turn off the backlight on an Acer keyboard. How to turn on the backlight on your keyboard

Can be turned on and off using keyboard shortcuts. For example, to enable it on a Lenovo ThinkPad T series, you need to use the Fn+Space key. Many laptop users often ask if Windows 10 has a special setting to adjust brightness. The answer is yes and no.

Setting the backlight color on the laptop keyboard.

Not all laptops have backlit keyboards. To check if your laptop has a backlit keyboard, go to the support page on the developer's website or use the device's instructions. Find the model you need and its parameters, and then check the technical specifications of your laptop. You can also determine the presence of this feature visually - carefully examine the additional function keys on the device. They are usually marked with symbols of a different color on the F1-F12 buttons or on the arrows. In most cases, to use additional hotkey functions, you must also hold down the Fn (Function) button, if available.

How to turn on the backlight

Unfortunately, Windows 10 doesn't have built-in components for customizing button lighting. But some major manufacturers offer their own software to change the default button lighting settings. For example, Dell on Windows 10 offers settings to turn on the keyboard backlight, adjust brightness, and automatically turn off after 5, 10, 30, 60, 300 seconds of inactivity. To view all the settings, Dell users need to open the Keyboard Properties setting and then go to the Backlighting tab.

Asus and Acer

Turning on the backlight on an Asus laptop is done in a couple of clicks. To start:

1. Make sure the feature is enabled in the BIOS.
2. Make sure you have updated your drivers (enter your model number and install your keyboard driver).

When the light sensor is active, the ASUS button LEDs will automatically turn the LED on/off according to the surrounding environment. For manual settings, most Asus laptops use Fn+F4 (to turn on the backlight and increase its brightness) and Fn+F3 (to decrease the brightness and completely turn off the diodes). If the Acer laptop keyboard backlight does not work, use the Fn+F9 key combination, or the special keyboard backlight button located on the left.

Sony and Lenovo

Sony also offers standard keyboard brightness settings options on some of its models. To see the settings, you need to open VAIO Control Center, and then click “Keyboard” and “Mouse” - “Keyboard Backlight”. Here you can configure the software to automatically turn the diodes on or off based on ambient light. Like Dell, Sony also offers the ability to automatically turn off the diodes after inactivity with the keyboard. To disable the feature, uncheck the box next to the "Turn on backlight in low light conditions" button. Here you can also set the automatic mode and time interval - 10 s, 30 s, 1 minute or “Do not turn off”. Lenovo is not opening new horizons for the use of diodes. Turning on the keyboard backlight on a Lenovo laptop is quite simple - using the Fn + Space key combination. That is, when you press Fn+Spacebar once, the driver will turn on the backlight at medium brightness. Pressing Fn+Space will increase the brightness. Pressing the hotkey again will turn off the keyboard backlight completely.

HP

On the road at night or at a presentation in a dark room, it can be quite difficult to see the laptop keyboard. To avoid such hassles, choose HP Pavilion models with under-keyboard backlighting that illuminates every key. The highlight symbol usually appears on the left side of the space bar. If this function is enabled, you will not have to turn on the light to type a letter or other text. Depending on the laptop model, diodes can be activated in several ways:

1. Turn on the laptop and press the “F5” or “F12” key (depending on the model).
2. Find the "Fn" key next to the Windows button at the bottom left of your keyboard. Press Spacebar while holding Fn to turn on the backlight.
3. Press the key light button if your laptop model has one. A special backlight button is marked with three dots in a horizontal line (found in dv6-2022er, dv6-3250us and other dv6 series laptops).

If none of the combinations work, try the entire row of function keys. The key you need may be in a different location. If still nothing happens, check your BIOS settings. To do this, in the BIOS, select BIOS Setup or BIOS Setup Utility, and then use the arrow keys to navigate to the System Setup tab. Be sure to enable Action Keys Mode (set it to Enabled) if it is disabled.

If the lighting lasts only a few seconds, you may need to adjust the timeout in the BIOS:

• Restart your laptop and immediately press F10 until the BIOS opens.
• Then use the arrow keys to navigate to the Advanced tab.
• Go to Built-in Device Options and press Enter.
• Here, select the Backlight keyboard timeout.
• Press Spacebar to open Settings, then select the delay you want.

IMPORTANT. If you select “Never”, the diodes will be active constantly, which will lead to rapid battery drain.

If the BIOS does not have this setting, the feature is most likely not supported. More detailed information can be obtained from the operating instructions or on the manufacturer’s website for the laptop model. To adjust the brightness (if your laptop supports this function), press the function button two or three times in a row. If it doesn't work, try pressing Fn together with the function key.

MacBook and Microsoft

All recent MacBook models automatically adjust brightness in low light using a built-in light sensor. You can also configure settings manually using hotkeys. Settings for automatically turning off diodes after a certain period of inactivity are located in the Boot Camp Control Panel. To open it, right-click the Boot Camp icon on the taskbar and select “Boot Camp Control Panel.” Microsoft Surface users can use Alt+F2 to increase keyboard brightness, and Alt+F1 to decrease keyboard brightness. Other popular manufacturers such as HP, Asus and Toshiba do not offer settings for adjusting keyboard brightness.

Shutdown

When it comes to saving battery, one of the most effective methods is to turn off the device's keyboard backlight. This feature is a huge advantage of all portable gadgets. But, unfortunately, not all laptop models support it. Let's look at turning off the lighting using the Microsoft Surface Pro as an example. Surface Pro has a built-in sensor that activates a diode under the buttons to make them stand out better. If your Surface is plugged into a wall outlet, you won't have any problems with power consumption. But if it is powered by a battery, activating the diodes will speed up the discharge of the battery several times!

IMPORTANT. The developers at Linus Tech Tips recently conducted power-saving tests that showed that turning off the backlight extended battery use by about 16%.

Other useful settings to save battery power:

• Remove peripherals, mouse and keyboard (20%-30% more battery life per charge).
• Reduces display brightness by up to 50% (16% more battery life).

The lighting turns on and off automatically using a built-in sensor. There are also manual option controls, but older versions of the Surface Keyboard may not have them. The first two keys next to Esc are the function buttons F1 and F2, which control the lighting on the device. If you just click on them, nothing will happen. More precisely, pressing F1 or F2 will not change the brightness of the backlight or turn it off/on. To access special Surface Keyboard features, you need to hold Alt:

• Increase brightness – Alt+F2.
• Decrease brightness – Alt+F1.

If you need to squeeze maximum battery life out of the Surface, you'll have to give up such goodies. Of course, in some situations, for example, in the dark, backlighting is simply necessary, so the manufacturer has provided an increase or decrease in brightness.

How to change the keyboard backlight color

Some laptop models are equipped with different colors. For example, Dell Latitude 14 Rugged 5414. The Latitude Rugged series features a backlit keyboard that can be manually customized. The following colors are available:

• White;
• Red;
• Green;
• Blue.

Alternatively, in System Setup (BIOS), you can configure the system to use the two installed secondary colors. To turn LEDs on/off or adjust brightness settings:

• To activate the switch, press Fn+F10 (if Fn lock is enabled, the Fn key is not needed).
• The first use of the previous button combination turns on the lighting at minimum brightness.
• Pressing the key combinations repeatedly cycles through brightness settings of 25, 50, 75 and 100 percent.
• Try several options to find the right one or turn off the light under the keyboard completely.

To change the color of the diodes:

• To view available colors, press Fn+C.
• By default, white, red, green and blue are active. You can add up to two custom colors in System Setup (BIOS).

Setting up a backlit keyboard in System Setup (BIOS):

1. Turn off your laptop.
2. Turn it on and when the Dell logo appears, press the F2 key several times to open the System Setup menu.
3. From the System Setup menu, select RGB Keyboard Backlighting. Here you can enable/disable standard colors (white, red, green and blue).
4. To set a custom RGB value, use the input fields on the right side of the screen.
5. Click Apply Changes and Exit to close System Setup.

IMPORTANT. The keyboard has a Fn key lock feature. When activated, secondary functions on the top row of keys become standard and no longer require the use of the Fn key. Fn lock only affects the F1 to F12 buttons.

To lock Fn, press Fn+Esc. Other secondary function keys on the top row are unaffected and require the use of the Fn key. To disable the lock, press Fn+Esc again. The function keys will return to their default actions.

Today, most mid- and high-end laptops offer backlit keyboards. Backlit keyboards make typing in low-light environments easier, especially for those who cannot touch type. If you already have experience setting up the keyboard backlight on a laptop, share your impressions in the comments below this article.

Basically, all technical devices that we use in everyday life are backlit. Sometimes there is no need for it and we want to turn it off. For example, such a backlight exists in almost all webcams, thanks to which the degree of illumination of a certain area around it improves. Let's look at how to turn off the backlight on a webcam.

Turning off the backlight in the webcam

• Many webcams have a special button that turns the light on and off. Some models have a button that allows you to adjust the brightness of the light. Therefore, you need to carefully inspect the device for the presence of such a button. For example, the Sven webcam, model 730 WEB, has such a button at the bottom of the body.
• If your device does not have a backlight adjustment button, you need to open the program that you installed along with the camera drivers. In the main menu there is an item responsible for managing the settings configuration; it will contain the necessary entry.
• If the webcam is used as a program application, you need to open its configuration and find the command to turn off the backlight there.
• Next, open the main menu of the system and find the item responsible for setting up equipment, such as a printer, scanner, etc. In it we find the camera settings and using the left or right mouse button we will open a window and try to find the function that is responsible for turning off and connecting the device’s backlight.
• There is another option to turn off the webcam backlight. To do this, you need to download an additional program that will allow you to manage your computer devices. Please ensure that it is compatible with the hardware configuration. There are a lot of such utilities on the Internet.
• If you can’t turn off the backlight, you can reinstall the drivers and look at the instructions for using the webcam.

You don't always need a phone keyboard backlight, as it drains the battery. This feature can be easily disabled. Let's look at how to turn off the keyboard backlight.

Turn off the backlight on your phone

• We go to the phone menu, look for settings, these could be display brightness settings or some other settings that affect battery performance. For example, in Samsung phones you need to go to settings, find the display and find the backlight item there.
• If you have a Nokia smartphone on the Symbian platform, you need to find the style configuration in the general settings menu and disable the indicator light blinking function. Then you need to go to the light sensor menu and adjust the screen brightness. Almost all new phone models have a power saving mode, which can be entered using the power button.
• To navigate the functions of your phone, you need to carefully study the interface and remember where you entered and where you changed the parameters. Then you won't have any problems.

If there is a need to turn off the logo backlight, you need to contact the service center, since this is not possible in all models of technical devices. For example, in order to disable the logo on HP. You need to open the cover and unsolder the LED, you can close the contacts.

A switch with LED or neon lighting is no longer uncommon in homes. The use of such switches is quite practical. In the dark, you don’t have to search along the wall with your hand to find the switch. With the advent of LED and CFL lamps, big problems began to arise. In particular, most modern LED lamps blink when the switch is off. Today we’ll figure out how to turn off the backlight on the switch.

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

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

How to turn off the backlight on a switch

1 of 2

Disconnect the part where the LED is

Disassembled switch with LED inside

First we need to dismantle the switch. Disconnect from conductors by first disconnecting the switch from electricity. For those who have already done this more than once, it’s a “trifling” task.

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

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

Illuminated switch connection diagram

If you quickly sketch out a diagram for connecting the backlight in the switch? then it will look like this:

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

To correct the situation, we need to replace the resistor. In our case, we take a 220 kOhm resistor and a 1 N 4007 diode. The diode can be removed from an energy-saving lamp, where it is used as a diode bridge. The circuit of the converted switch will look like this:

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

How to turn off the video switch backlight

And finally, watch the video again on how to turn off the LED or neon lighting from the switch so that the lamps do not blink. This is a radical solution to the problem. We just bite out all the radio components and don’t worry anymore. However, this method of dealing with blinking does not satisfy me, so it is better to use the above example. And the switch does not need to be turned into a simple key and the functions remain.

One of the indicators of a laptop’s ergonomics is the backlighting of its keyboard. This function greatly simplifies working with the device both at night and during the day in low light levels. 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, we will consider all possible options.

Turn on the keyboard backlight

Before you try to activate the keyboard backlight, you need to know for sure that this function is present on your laptop model. And if you don’t want to look for technical specifications and re-read the user manual, then you should take a closer look at the special symbols printed on the function keys F1 - F12. Typically, the keyboard backlight icon looks like this and is located on the F4 button.

After finding the symbol you are looking for, you must simultaneously press the Fn+F4 combination. At the same moment, all the keys on the keyboard will begin to light up. If pressing Fn+F4 did not give a positive result, then you can search for the backlight by alternately pressing Fn and other function buttons. It is worth keeping in mind that during a random search for the desired combination, other functions will be activated, the operation of which can be disabled by pressing the previous combination again.

In some models, the keyboard backlight option is assigned to the Fn + “space” key combination, for example, in the Lenovo Z500 model. Or it is placed 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 the backlight on and off, but also control the brightness of the LEDs. For example, the Asus FX series gives the user the opportunity to independently select one of three brightness modes. Here, the brightness is increased by pressing the Fn+F4 keys, and the brightness is decreased by pressing the Fn+F3 keys. At the same time, a sign appears on the screen indicating the current brightness level.
Unfortunately, users are not always able to turn on the button backlight in the standard way. This problem especially often occurs after reinstalling the OS, as a result of which the laptop lacks the appropriate driver. To solve the problem, you need to find the backlight driver on the manufacturer’s official website, download it and install it on your laptop.

Shutdown

When the need for backlighting disappears, it can be turned off. But, just like with turning on, there is no single standard shutdown button. All models implement this function differently, for example:

• disabling is done using the same combination of buttons as turning on (Fn+F4, Fn+Space);
• to turn it off, use the function button located next to the power button;
• The backlight turns off in several stages by repeatedly pressing Fn and the function key with the keyboard icon.

How to change the keyboard backlight color?

Today, most laptop manufacturers assemble keyboard backlighting using single-color LEDs, as a result of which the user cannot change its color. However, there are also models in which the backlight is based on RGB LEDs. For example, Asus uses multicolor LEDs in its new laptops, the operation of which can be controlled using the patented Asus Aura software. Owners of such devices can change the color and brightness of LED indicators at their discretion, choosing a background that is pleasing to the eye.

In addition to Asus Aura, there is a universal Steel Series Engine program that is compatible with all laptop models. With its help, you can set the color of the LEDs, as well as use other features of the multifunctional menu.

If the computer keyboard has a single-color backlight, which does not help, but rather irritates the eyes, then you can modify it yourself in one of two ways. In the first case, you need to disassemble the keyboard, remove the backlight board and determine the type of LEDs installed on it. After this, they can be replaced with LEDs of the same size, but of a different color.

The second option involves disassembling the keyboard and sticking stickers made of translucent paper (yellow, green, blue) onto the backlight board. After assembly, the keys will glow with orange, azure and violet light, which will have to pass through a paper filter.

For a laptop that has never had a backlight, you can make an external miniature USB lamp with bright LEDs with your own hands. Or buy a ready-made USB LED backlight for your keyboard via the Internet.
