If you are having problems turning on your Lenovo laptop backlit keyboard, there are many things you can do. Some of these methods involve resetting your system, while others may require you to contact Lenovo support.
The first step in resolving the issue is to restart the computer. To do this, you will need to press the power button on your computer for at least 10 seconds, then remove the power cable and reconnect the AC adapter.
Next, check the backlight timeout settings. These can be found in the BIOS. You can set the timeout for as low as 5 seconds, which will allow you to save battery power without having to turn the light off.
You can also try turning on your laptop’s backlit keyboard with the Fn key. This key is located near the Windows and Ctrl keys. For Lenovo laptops, the backlight icon usually appears on the space bar.
Another method for turning on your backlit Lenovo keyboard is to use the keyboard’s built-in feature. Most Lenovo computers come with this feature, but there are some models on the lower end of the price range that don’t have it.
Finally, you can install a program to turn your keyboard on or off. Generally, these programs are installed with the computer, but if they aren’t, you can download them from Lenovo’s website.
As with most computer issues, you will need to determine what is causing the problem. It may be a hardware or software glitch. Or, it may be an unexpected buildup of energy inside the backlight system.
