The method of lighting up the keyboard light varies from device to device. First, confirm the keyboard type and find the corresponding switch or settings. The keyboard backlight of the notebook can be turned on through Fn specific function keys (such as Dell Fn PrtSc, Lenovo Fn space), or can be adjusted through system settings or brand driver software (such as Asus Armoury Crate, Lenovo Vantage); in an external mechanical keyboard, you may need to press Fn Esc or arrow keys to activate the light after plugging in the wired keyboard, and try Fn F keys or supporting software settings on the wireless keyboard; if the keyboard light is not on, check whether the battery is sufficient, whether the driver is installed, whether the shortcut keys are locked, and finally consider whether there is a hardware failure. Following the above steps to check can basically solve the problem.

It is actually quite easy to light up the keyboard light, but the operation of different devices is different. The key is to confirm your keyboard type first, and then find the corresponding switch or setting method.

How to turn on the keyboard backlight with your laptop

Many thin and light notebooks and gaming notebooks have their own keyboard lights, and there are usually two ways to turn them on:

• Shortcut key control : The most common combination is Fn 特定功能鍵(there is usually a small light bulb or keyboard icon on this key). For example, Dell may be Fn PrtSc , and Lenovo may be Fn 空格. It depends on your keyboard logo.
• Adjustments in system settings : Some brands support setting brightness, color and even dynamic effects in pre-installed driver software. These options are provided by Asus' Armoury Crate and Lenovo's Vantage.

If you can't find the shortcut key, you can try going to the "Keyboard" or "Show" related options in the system settings to see if there are any backlight adjustments.

How to turn on external mechanical keyboard lights

The situation of external keyboards is a little more complicated, it mainly depends on what type of keyboard you are buying:

• Wired mechanical keyboard : Most mechanical keyboards with RGB or monochrome backlight can light up when plugged in. Some are turned off by default and need to be activated by pressing specific key combinations. Common ones such as:
  • Fn Esc or Fn 方向鍵上下
  • Some brands will have exclusive switching keys, such as Razer's Fn 數(shù)字鍵1~3 to change the light effect
• Wireless/Bluetooth keyboard : In order to save power, this type of keyboard may not automatically turn on by default. You can try pressing Fn 某個(gè)F鍵(usually F5, F9, etc.), or it may be possible to manually turn on the backlight in the supporting software.
• Keyboards without driver design : Some simple-style keyboards do not have software control, and can only switch lighting modes through key combinations. It is recommended to check the instructions or the instructions on the official brand website.

What should I do if the keyboard light doesn’t light up?

Sometimes you will find whether the keyboard light should be on or not. At this time, you can check these common problems:

• Insufficient battery : Especially for wireless keyboards, the backlight will be automatically turned off when the battery is low to extend the usage time.
• Driver or software is not installed : Especially for high-end mechanical keyboards, if the official driver is not installed, some lighting functions may not be enabled.
• Shortcut keys are locked : Some keyboards support locking the backlight switch state, which may be turned off by accident.
• Hardware failure : If it is an old keyboard, it may be that the lamp beads are damaged. In this case, it must be disassembled and inspected or replaced.

Basically these are the operations. Different keyboard models vary slightly, but the general direction is to find shortcut keys, read the manual, check the power supply and driver. Don't rush to suspect that it's broken, try the most basic steps first.
