Power Conservation: Dell Inspiron 3800 System Reference
Power Management Properties for Microsoft Windows NT
Dell provides Softex software compatible with the Power Management Controller, which allows
you to suspend and resume operation of your portable computer without affecting your ability to
use the docking station or its media bay.
Save-to-Disk Suspend Mode
Save-to-disk suspend (S2D) mode copies all system data to a reserved area—the S2D
partition—on the hard-disk drive and then turns off all power to the computer. When you
resume normal operation, the same programs will be running and the same files will be open
that were loaded before you activated this mode.
Place the computer in S2D mode if you intend to store the computer for longer than 40 days.
S2D mode preserves the configuration information stored in nonvolatile random-access
memory (NVRAM). Typically, the reserve battery maintains this information, but it may run out
of energy after 40 days.
NOTE: S2D mode helps preserve system data by saving it to the hard-disk
drive if you are about to run out of battery power.
To activate S2D, press <Fn><a> (or <Scroll Lock><a> on an external keyboard if the External
Hot Key option is enabled in the System Setup program). On a French keyboard, press
<Fn><q> or <Scroll Lock><q>.
NOTE: With systems running under ACPI, settings for power management
features, such as key combinations, External Hot Key, and S2D mode are
controlled from the Power Management Properties window in the Control
Panel. The key combinations of <Fn><a> or <Scroll Lock><a> may not
function with ACPI if the settings have not been activated from the Power
Management Properties window.
The S2D mode is referred to as the hibernate mode for systems running
ACPI. To activate the hibernate mode, make sure that you have configured
the appropriate key combinations from the Power Management Properties
window.
