Standby Mode; Hibernate Mode - Fujitsu LifeBook T Series User Manual

Standby Mode

Standby mode in Windows saves the contents
of your Tablet PC's system memory during
periods of inactivity by maintaining power to
critical parts. This mode will turn off the CPU, the
display, the hard drive, and all of the other internal
components except those necessary to maintain
system memory and allow for restarting. Your
Tablet PC can be put in Standby mode by:
• Pressing the Suspend/Resume button when
your system is turned on.
• Selecting Standby from the Windows Shut
Down menu.
• Timing out from lack of activity.
• Allowing the battery to reach the Dead Battery
Warning condition.
• Closing the system cover.
Your Tablet PC's system memory typically stores
the file(s) on which you are working, open
application(s) information, and any other data
required to support the operation(s) in progress.
When you resume operation from Standby mode,
your Tablet PC will return to the point where it
left off. To resume operation, you must use the
Suspend/Resume button to resume operation,
and there must be an adequate power source
available, or your Tablet PC will not resume.
If you are running your Tablet PC on battery
power, be aware that the battery continues
to discharge while your Tablet PC is in
Standby mode, though not as fast as when
fully operational.

Hibernate Mode

The Hibernate mode saves the contents of your
Tablet PC's system memory to the hard drive as
a part of the Suspend/Resume mode. Your Tablet
PC is preconfigured to perform this function. The
Hibernate mode can also be configured through
the system BIOS to run in other ways depending
on what you need to accomplish.
Standby or Hibernate modes should not
be used with certain PC Cards. Check
your PC Card documentation for more
information.
Disabling the Suspend/Resume button
prevents it from being used to put your
Tablet PC in Standby or Hibernate mode.
The resume function of the button cannot
be disabled.
If your Tablet PC is actively accessing
information when you enter Standby or
Hibernate mode, changes to open files
are not lost. The files are left open and
memory is kept active during Standby
mode or the memory is transferred to the
hard drive during Hibernate mode.
When PC Cards or external devices are
in use, Save-to-Disk mode cannot return
to the exact state prior to suspension,
because all peripheral devices will be
reinitialized when the system restarts.
The main advantage of using Hibernate
mode is that power is not required to
maintain your data. This is very important
if you will be leaving your Tablet PC in a
suspended state for a prolonged period
of time. The drawback of using Hibernate
mode is that it lengthens the power down
and power up sequences and resets
peripheral devices.
