The other option, Timeout mode, adjusts the keyboard light based on your use of the computer and keyboard, respectively. It's totally up to you, but this time, the keyboard light won't stand in your way. If you crank up the energy setting, the keyboard will be bright and shiny. This means that if you have battery saving mode on, your keyboard will be as dim as possible. Persistent mode will adjust your laptop's backlight keyboard depending on your battery settings.
These modes basically deal with the same issue, only in a somewhat different way. Make sure you find the best option for you, and choose between Persistent and Timeout mode. Keeping your Lenovo Ideapad laptop in battery saver mode could always be more efficient were it not for that pesky backlight keyboard, right? Well, you won't have to worry about it anymore, according to the developer of Auto Keyboard Backlight, because your laptop will be forced to dim the keyboard light depending on the battery settings you have on. Built using Release configuration of the setup project. Windows Installer for Auto Backlight for ThinkPad.
