To suspend system operation:
1. Press the Suspend/Resume button, or carry out the
Standby command from your operating system or
power management program. (If your system is
configured to suspend operation using Hibernate
(Save-to-Disk) mode, which is explained later in this
procedure, a message is displayed while data is saved
to your hard disk.)
C A U T I O N
If you are replacing the battery, wait until system
operation is suspended and the power icon is flashing
before you remove the battery. Failure to do so could
result in loss of your unsaved data. (Note that if the
Resume On LAN function is enabled in the BIOS setup,
you should not remove the battery unless the system is
shut down. When Resume ON LAN is enabled, the
bridge battery is disabled in order to optimize battery
life.)
2. The Power icon either flashes (Suspend-to-RAM) or
is not displayed (Hibernate) when system operation
is suspended, depending on how your system is
configured. At this point, programs that were
running are stopped, active data is saved, and the
system enters one of two different low-power states,
or suspend modes, as explained in the following
paragraphs.
3. Observe the Power icon in the Status display to deter-
mine which suspend mode your system is using.
• Power icon is blinking: Suspend-to-RAM mode.
In this mode, active data is saved by maintaining
power to RAM while most other system components
are powered off. The Battery Gauge icon in the Status
display indicates the battery charge level.
• Power icon is not displayed: Hibernate (Save-to-Disk)
mode.
In this mode, active data is stored on the hard disk
drive and power usage is reduced to the same level
used in the Off state. When the system is in Hibernate
mode, the Battery Gauge icon is not visible in the
Status display. In this mode, there is no danger of
losing data if battery power is lost.
If you have successfully performed this procedure,
system operation is now suspended. Refer to
"Resuming System Operation" later in this chapter to
resume system operation. Also, note the following
with regard to suspending system operation:
U s i n g Y o u r S t y l i s t i c S T 4 0 0 0
• You can remove the battery while the system is in
Suspend-to-RAM or Hibernate modes in order to
install a charged battery. To prevent losing unsaved
data, wait until system operation has suspended
before you remove the battery. Note that after you
remove the battery, you have approximately five
minutes to replace it with a new battery or to plug in a
power supply before the bridge battery is depleted.
• Your system may be configured to suspend operation
automatically after a period of inactivity.
• Your system may be configured to enter Hibernate
mode automatically after a period of time in Suspend-
to-RAM mode.
• The system uses a small amount of battery power
when in Suspend-to-RAM mode. Eventually, the
battery will become fully discharged.
P O I N T
If you will not be using the system for an extended
period of time, shut down the system rather than using
Suspend-to-RAM mode.
• If the battery charge drops to a Low-Battery Warning
level while the system is running, the system will beep
periodically. If this occurs, suspend system operation,
shut down the system, or attach an external power
source, such as the AC adapter, to the Tablet PC.
• If the battery charge drops to a Critically Low level
while the system is running, the system is forced into
a pre-selected mode (Suspend-to-RAM or
Hibernate). If this occurs, you must either install a
charged battery, or connect an appropriate external
power source such as the AC adapter before you can
resume system operation. (If the battery charge drops
to a Critically Low level while the system is in
Suspend-to-RAM mode, the system stays in Suspend-
to-RAM mode until power is restored or totally
dissipated.)
• Suspending system operation interrupts data
communications; therefore, some programs may
block the system from suspending to prevent an
interruption.
• The suspend action of the Suspend/Resume button
may be disabled to prevent accidental interruption. If
this is the case, pressing the Suspend/Resume button
will not suspend system operation as described here.
(In this case, suspend mode can only be achieved
using the system software). Contact your local help
desk or reseller if your system configuration is not
suitable.
