Enabling/Disabling Ambient Light Sensor
The ambient light sensor is located towards the bottom of the panel on the right of the display. This sensor
automatically senses the light conditions in which the computer is operating. If the lighting is very bright,
the brightness of the LCD will increase to make it easier to see the display. Conversely, if it is used in a
darkened room, the display will automatically dim.
The light sensor can be enabled or disabled from the Control Panel as follows:
1 Open the system Control Panel and click in the View by: field, select either large or small icons.
2 Click on the Location and Other Sensors icon.
IF USING AC POWER, YOUR BRIGHTNESS SETTING IS SET TO ITS HIGHEST LEVEL BY DEFAULT. IF USING
BATTERY POWER, YOUR BRIGHTNESS SETTING IS SET TO APPROXIMATELY MID-LEVEL BY DEFAULT.
T
HE HIGHER THE BRIGHTNESS, THE MORE POWER THE SYSTEM WILL CONSUME AND THE FASTER YOUR
BATTERIES WILL DISCHARGE. FOR MAXIMUM BATTERY LIFE, SET THE BRIGHTNESS AS LOW AS
POSSIBLE.
N
OTE THAT WHEN YOU FIRST START YOUR SYSTEM, THE AMBIENT LIGHT SENSOR IS DISABLED. YOU
WILL INITIALLY NEED TO ENABLE IT USING THE FOLLOWING STEPS.
