If you just bought yourself a Dell laptop and you’re wondering how the hell you can turn off the keyboard backlight so that you can save some battery power, there’s a way.
Dell gives an option to turn off the keyboard backlight in the Windows Mobility Center. All you need to do is right click on the battery icon in your system tray and click on Windows Mobility Center. The Mobility Center Window pops up and you can either adjust the brightness of the keyboard backlight or even turn it off completely.
Clicking on the keyboard thumbnail leads to a new settings window from where you can control more aspects of keyboard backlighting. You can tell after how much time the backlight should be disabled whenever there is keyboard activity.
Another tip: Pressing the Fn key and the right arrow together also adjusts the backlight. Thanks Shivaranjan.
Other manufacturers also must provide such options but I haven’t really used any other laptops. Anyone can share more info and enlighten us in the comments.
