Idle Mode
Idle mode is one of the power management
parameters. When Idle mode is enabled the
CPU is put into low-speed operation when
there is no activity (keystroke, pointer action,
sound generation, video display change,
modem transmission or reception, etc.) on
your notebook for 16 seconds. Any activity
will cause the normal operation to restart
automatically. This feature is independent of
the Suspend/Resume button. This parameter is
enabled and disabled in the BIOS setup utility.
(See page 87.)
Standby Mode
Standby mode is one of the power management
parameters. When Standby mode is activated,
your notebook puts the CPU in low - s peed oper-
ation,shuts off the display and turns off the
hard drive when there is no activity (keystroke,
pointer action, sound generation, video display
change,modem transmission or reception,
etc.) on your notebook for the user selected
time-out period. (See page 88.) Any activity

The main advantage of using the Save-to-
Disk function is that power is not re q u i re d
to maintain your data. This is part i c u l a r l y
i m p o rtant if you will be leaving your note-
book in a suspended state for a pro l o n g e d
period of time. The drawback of using
Save-to-Disk mode is that it lengthens the
power down and power up sequences and
resets peripheral devices.
P O I N T
Save-to-Disk mode requires allocating a
significant amount of hard drive capacity
for saving all of system memory, which
reduces your usable disk space. When
you purchase your notebook it will have
space allocated for the memory installed.
If you upgrade the original system by
adding a memory upgrade module
without changing the size of your Save-
to-Disk allocation you will get an error
message when you try to activate the
Save-to-Disk mode and it will not work.
Use the PHDISK Utility to increase
the size of the Save-to-Disk file,
SAVE2DSK.BIN. (Refer to Setting Up
Your Save-to-Disk File Allocation on
pages 99-100 for more information.)
