Closing the Display

One way to conserve power on the computer is to close the display when the computer is not in
use. When you close the display and an external monitor is not connected, the computer's
liquid crystal display (LCD) shuts off automatically. If you set the Display Close option in
System Setup to Standby, the computer enters the standby mode when the display is closed. If
you set the Display Option to Active, the display shuts off when it is closed and the computer
does not enter the standby mode.
NOTE: If an external monitor is connected when you close the display, the
computer does not activate standby mode. You can still use the external
monitor.
If the computer detects a wakeup alarm or receives a modem call while the display is closed,
the computer handles the alarm or answers the call. After such input/output (I/O) activity
ceases, the computer waits 1 minute before reactivating standby mode.
To resume work, open the display. (The computer may take several seconds to resume
operation.)
NOTE: With systems running under ACPI, settings for these features are
controlled from the Power Management Properties window in the Control
Panel. To conserve power, use the sleep mode. Activate the sleep mode by
selecting Sleep from the Power Management Properties window.
