Depending on the configuration and the specific make and model of the notebook, this key can be activated alone or in conjunction with the Fn key, which is usually found on the bottom row of the keyboard.

What to do if the keyboard backlight keys are not working or are missing

In case you can't find the keyboard backlight enable key, your laptop may not be equipped with it.

Important point: Laptops of the same model, but with different modifications, can be with or without a backlit keyboard. Taking the Acer Aspire 3 as an example, some of this notebook's mods will have a backlight symbol on the F9 or F8 key, while others will not. In the latter case, the reason is that there is no backlight function.

The following is a common situation: Laptop keyboard backlight keys are there, but not workingNothing changes when you press them.

Usually the reason is the lack of necessary utilities from the manufacturer, as examples, but it is not a complete list and even within the same brand for different models the utilities may be different:

  • In MSI's case, System Control Manager (SCM) and other things like SteelSeries Engine for the brand's gaming laptops.
  • For Acer - Quick Access Application.
  • ASUS ATK Package or Hotkey Utility.

Possible solutions to the problem in this case:

  1. Go to the official support page of your laptop model (write a search query in Google or Yandex like: "laptop model support" and in the results open the official website) and download the necessary utilities from there (usually found in the drivers section).
  2. If you cannot determine what you need to download, you can specify the exact make and model of your laptop (usually on the sticker at the bottom) in the comments of this article and wait for my response, I usually respond to comments once a day.
