Enabling/Disabling Ambient Light Sensor (Windows 7 only)
Systems which are running the Windows 7 operating system have an ambient light sensor (just below the
Power/Suspend/Resume switch) that 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.
3
To enable or disable the Light Sensor utility, check or uncheck the box in the Enabled column.
