If the F8, F9, and F10 keys are marked with illumination icons, then your computer has keyboard illumination and an ambient light-sensing (ALS) system. The ALS sensors are located under the speaker grilles and will automatically adjust the brightness of your display and keyboard illumination according to the light available in your current environment. You can also adjust the keyboard illumination using the F8, F9, and F10 keys.

Important: Even when the keyboard illumination feature is on, the keyboard illuminates only in low-light situations.

mChoose Apple (K) > System Preferences from the menu bar. Open the Displays pane and deselect the automatic brightness checkbox.

You can turn off the keyboard illumination feature in the Keyboard & Mouse pane of System Preferences or by pressing the F8 key.
