Suspend Time-Out
SUSPEND TIME-OUT
lets you determine how long your
computer remains idle before activating suspend mode to
conserve battery power.
Settings for this option in both
AC
and
BATTERY
are:
To increase battery operating time, set the
SUSPEND
TIME-OUT
option to a lower number of minutes.
NOTE: Set the
SUSPEND TIME-OUT
option to
DISABLED
if
using it causes compatibility problems with your software.
A change to the
SUSPEND TIME-OUT
option takes effect
immediately (rebooting is not required).
If you are not in the System Setup program, you can acti-
vate suspend mode at any time by pressing <
FN
><
ESC

The computer resumes normal operation automatically when

System Memory
SYSTEM MEMORY
displays the total amount of dynamic
random-access memory (DRAM) installed in your
computer.
The amount of memory displayed includes the standard
16 megabytes (MB) of system memory (permanently
installed on the system board), plus any memory modules
installed in your computer.
There are no user-selectable settings for this option. The
amount of memory displayed changes if you install or
remove a memory module.
Possible settings for this option are:
System Switch
SYSTEM SWITCH
allows you to use the power switch
as a regular power switch or to enable and resume from
suspend-to-disk mode.
If you want the power switch to turn the computer on and
off, set this option to
ON/OFF
(the default). If you want to
use the power switch to activate and resume from suspend-
to-disk mode, set this option to
S2D/RFD
.
NOTE: If the computer is in suspend-to-disk mode, press-
ing the power switch always causes the computer to resume
normal operation.
When this option is set to
S2D/RFD
, slide the power switch
forward to activate suspend-to-disk mode. If the computer is
already in suspend-to-disk mode, slide the switch forward to
resume normal operation.
If the
SYSTEM SWITCH
option is set to
S2D/RFD
and the
computer is not in suspend-to-disk mode (that is, if there is
no data in the S2D partition), pressing the power switch starts
the computer normally.
Time
TIME
resets the time on the computer’s internal clock.
Time is kept in a 24-hour format (hours:minutes:
seconds).
NOTE: If a network server controls the time reflected by
the
TIME
option, changing this option has no effect.
