20 Chapter 2 The Basics
Adjusting Your Display
Once you begin working with your new PowerBook, you may need to adjust your
display so that the screen is easier to see. Use the keys labeled with the ¤ icon to
adjust screen brightness.
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.
To turn off the automatic display brightness feature:
m
Choose 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.
