You can try installing a utility for working with hot keys on your laptop (downloaded from the laptop manufacturer’s website). Perhaps the absence of such a utility prevents unlocking the buttons using a combination with the Fn key.

Hotkeys

If the cloth was not wet and liquid did not get inside the case, then this problem can be eliminated quickly enough. Most likely, you accidentally pressed a keyboard shortcut that disables the built-in input device.

Some laptops use a combination of the Fn function button and one of the F1-F12 keys. for example, FnF1. to turn the keyboard on / off. To understand which key you need, take a close look at the icons. Look for a lock button, if you press it together with Fn, the keyboard will be locked.

If you need to turn on only the block with the numbers of the case, press Num Lock or the combination of FnNum Lock. If these combinations DO NOT help, look for the correct combination in the instructions for the laptop.

Enabling laptop keyboard

If you accidentally blocked the built-in device or the buttons stopped responding as a result of an error, then to fix the problem you need to know how to turn on the keyboard on a laptop.

Hardware failure

If water gets on the keyboard, or the laptop was subjected to mechanical stress, you should contact the service. But you can try to independently determine the extent of damage to the laptop. See if the USB ports, network cable connector, and touchpad are working. If these components are also inactive, then the prerequisite for the problem is the failure of the south bridge of the motherboard.

If one keyboard does not work, try to disassemble the laptop yourself (provided that the warranty has already expired) and check the flex cable. Before opening the case, it is recommended that you read the disassembly guide for your model to avoid damaging fragile components.

On many laptops, the keyboard is held in place by recessed latches. You can move them away with a screwdriver. You should start from the left edge. Lift the edge of the keyboard with a screwdriver, pry the canvas with a needle, or gently pull the Esc key.

In this way, release the entire upper part of the keyboard so that it becomes possible to pull the canvas out of the case. You will see that the input device is connected to the motherboard with a ribbon cable. To remove it, you need to return the frame (there may be a different type of attachment, read the manual for your model).

Clean the contacts, and then reinstall the ribbon cable, securing it securely with the latch. If the keyboard or ribbon cable is damaged, you can replace it yourself.

How to change the color of the keyboard backlight

Most laptops have single color diodes. In this case, you will NOT be able to switch the hue. Their spectrum is formed on the basis of RGB (red, green and blue) lamps.

However, if you are the owner of a model that has a shade control function, then consider options on how to do this.

Option 1 (for multicolor). As you already understood, the color is based on RGB lamps. To switch to the desired color, for example, in Asus, the Asus Aura program is built in. In addition, it allows you to change the saturation and brightness of the lamps.

Steel Series Engine. Suitable for all modern laptops. The main part of the program settings is designed for gaming mice (to increase acceleration and sensitivity). For keyboards limited to a panel for adjusting color and brightness.

Option 2 (for monochrome). If the single color backlight is NOT useful, then you can change the LED lamps. To do this, you must disassemble the keyboard. Next on the board, change the Single-color lamps to LEDs of the required color. At the same time, given that the dimensions of the lamps must match.

Option 3 (for monochrome). This method does not require buying colored LEDs. Disassemble the keyboard. Glue translucent paper of the desired colors on the board. At your request, you can make a single color, for example, blue or depending on the groups of buttons. As a result, the light will pass through the stickers and glow with its color, creating a muted saturated backlight.

The structure of the laptop keyboard is slightly different from the computer layout of the buttons and the absence of an additional panel.

But when you enable the color of the buttons, there is a significant difference. As in laptops, the same situation is observed here with laptop models and manufacturers.

Since the keyboard is connected to a PC, changing it with a backlight is NOT difficult, unlike a laptop. You can also select components for PCs from different manufacturers, depending on the power and price category, or for what purpose by purchasing a computer. And also manufacturers offer modern touch panels with a large selection for customization.
