Welcome Faith Achieng,
Thanks for reaching out to Microsoft Q&A Forum. I understand you are having difficulty typing at night because you cannot find how to turn on your laptop keyboard light.
Could you please let me know:
- What is the brand and exact model of your laptop?
- Did the keyboard backlight work previously, or have you never seen the keyboard light turn on?
Please make sure you already tried the Q&A Assist steps. In addition, please try the following:
1, Check whether Windows recognizes keyboard lighting controls.
- Open Settings.
- Go to Bluetooth & devices.
- Check whether a Keyboard section with backlight controls is available.
2, Install available Windows updates.
- Open Settings.
- Go to Windows Update.
- Select Check for updates.
- Install available updates and restart the laptop.
3, Check the laptop manufacturer's official app if one is already installed.
- Open Start and search for the manufacturer's device-management application.
- Check its keyboard or lighting settings for a backlight option.
4, If you have never seen the keyboard illuminate, please provide the exact laptop model. Some laptop configurations may not include backlit-keyboard hardware, so the model will help determine whether this feature is available.
Please let me know the laptop brand and model, and I can guide you further.
