如果您使用的是背光或LED键盘，并且其照明突然打开或关闭有问题，那么我们将看看如何解决这个问题。许多笔记本电脑提供背光键盘，然后有许多支持LED的键盘。这两个键盘都提供了控制其灯光状态的配置，允许您自定义它们等等。
(Turn Keyboard)在笔记本电脑上打开或(Laptop)关闭(Off)键盘照明
在我们开始之前，背光(Backlit)键盘和LED键盘之间存在显着差异。前者依赖于环境光，而后者提供手动控制。我有一个LED键盘，我一直打开它只是为了看中。我们将在这篇文章中讨论以下主题：
- 打开或关闭背光键盘
- 打开或关闭 LED 键盘
- 软件配置
- 更新 BIOS
我们已经大致讨论了这个话题。如果您有来自OEM的关于此主题的文档，那么这是您的最佳指南。
1]如何(How)打开或关闭背光键盘？
大多数背光键盘处于自动模式(Backlit keyboards are in auto mode)。如果有足够的光线，它们将不会打开。您可以通过关闭灯来检查，如果它自动亮起，则表示它正在工作，您无需担心。
但是，如果它不亮，则在键盘上寻找一个独特的键，即照明图标(look for a unique key, aka illumination icon on the keyboard)（它可能与功能(Function)键组合使用），它可以增加亮度。苹果(Apple)提供两组按键，而惠普等公司使用相同的按键（F5、F9 或F11按键，或双动Fn + F5、F9 或F11按键），戴尔(Dell)使用F10，联想(Lenovo)使用Fn + Spacebar.
对于苹果(Apple)键盘，即使设置了最大亮度，键盘也不亮，但对于惠普或戴尔(Dell)，您可以强制开启。请记住(Remember)，这将取决于原始设备制造商(OEMs)，但每个人都会提供一个可以管理它的唯一密钥。
这是我在Apple MacBook Air上注意到的另一件事。如果显示器的亮度太高，它会变暗或关闭背光键盘。

2]如何(How)打开或关闭LED键盘？
LED 键盘有不同的概念。如果您喜欢根据您使用的东西不断变化的彩色灯光，或者您想设计您的想法，那么它们非常适合。我正在使用Corsair LED键盘，我可以使用他们的软件为各个键选择颜色。
像这样的键盘提供了一个可以控制亮度的专用按钮或照明图标 。( dedicated button or illumination icon )因此，如果我按三下，它会关闭所有灯。当我第四次触摸它时，它会将键盘点亮回到最大。如果您是键盘新手，并且不确定，请查找此类键或查看手册。
3]软件配置
有时OEM(OEMs)会为其键盘提供特殊软件，尤其是那些允许您重新映射游戏按键的(remap keys for gaming)软件。这个软件还可以关灯，即使你按下硬件，也不会发生任何事情。因此，如果有任何此类软件，并且您已更改它，请撤消它。
带有LED灯的游戏键盘通常就是这种情况。如果您在设计配置文件之间并把它放在中间，它可能已经关掉了灯。如果某些键有灯而其他键没有，您可以计算出来。
4]更新BIOS
我浏览了一些OEM(OEMs)手册，有些还建议更新 BIOS(update BIOS)。如果带有照明图标的按键不能按预期工作或被BIOS禁用，这将很有用。它将有类似的选择-
- 禁用或关闭：它将完全关闭键盘照明。
- 暗淡：它将照明设置为一半亮度。
- 明亮(Bright)- 键盘将以全亮度显示
我希望这些提示对您有用并帮助您打开和关闭键盘照明(Keyboard Lighting)。
How to Turn Keyboard lighting On or Off on a Laptop
Іf you are using a backlit or an LED keyboard, and have issues with its lighting turning on or оff all of a sudden, then we will take a look at how to resolve thiѕ. Many lаptopѕ оffer a backlit keyboard, and thеn there are many LED enabled keyboards. Both of these keyboards offer configuration whіch cоntrols their light states, allows you to customize them, and so on.
Turn Keyboard lighting On or Off on a Laptop
Before we start, there is a significant difference between Backlit keyboards and LED keyboard. The former is dependent on ambient light while the latter offers manual control. I have an LED keyboard, and I keep it turned on all the time just for the fancy. We will cover the following topics in this post:
- Turn on or off a backlit keyboard
- Turn on or off an LED keyboard
- Software configuration
- Update BIOS
We have talked about this topic in general. If you have a document from the OEM on this topic, then that is your best guide.
1] How to turn on or off a backlit keyboard?
Most of the Backlit keyboards are in auto mode. If there is enough light, they will not turn on. You can check that by turning off the light, and if it automatically lights up, then it means it is working, and you have nothing to worry about.
However, if it doesn’t light up, then look for a unique key, aka illumination icon on the keyboard (it might be available as a combination with Function keys), which can increase the brightness. Apple offers two sets of keys, while companies like HP use the same keys (F5, F9, or F11 keypress, or a dual-action Fn + F5, F9, or F11 keypress), Dell uses F10, and Lenovo uses Fn + Spacebar.
In the case of Apple keyboard, even if set the maximum level of brightness, the keyboard doesn’t light up, but in the case of HP or Dell, you can force it to turn on. Remember, this will depend on OEMs, but everyone will offer a unique key that can manage this.
Here is one more thing which I have noticed on Apple MacBook Air. If the brightness of the display is too hight, it will dim or turn off the backlit keyboard.

2] How to turn on or off an LED keyboard?
LED keyboards have a different concept. If you fancy colorful lights that keep changing based on what you use, or you want to design your idea, then they fit well. I am using the Corsair LED keyboard, and I can choose a color for individual keys using their software.
Keyboards like these offer a dedicated button or illumination icon that can control brightness. So if I press mine three times, it turns off all the lights. When I touch it for the fourth time, it lights up the keyboard back to the maximum. If you are new to the keyboard, and you are not sure, then look for such keys or check the manual.
3] Software configuration
Sometimes the OEMs offer special software for their keyboard, especially those who allow you remap keys for gaming. This software can also turn off the lights, and even if you press the hardware, nothing will happen. So if there is any such software, and you had changed it, undo it.
It is typically the case with a gaming keyboard with LED lights. If you were in between designing a profile and left it in between, it may have turned off the lights. You can figure it if some of the keys that have lights while others don’t.
4] Update BIOS
I have gone through some of the OEMs manuals, and some also recommend to update BIOS. It is useful if the keys with the illumination icon do not work as expected or are disabled from the BIOS. It will have similar options-
- Disabled or Off: It will completely turn off the keyboard illumination.
- Dim: It will set illumination at half brightness.
- Bright – The keyboard will appear at full brightness
I hope these tips were useful and helped you to turn Keyboard Lighting on and off.
