operation from Standby mode, your system will return
to the point where it left off. To resume operation, you
must use the Suspend/Resume button to resume opera-
tion, and there must be an adequate power source avail-
able, or your system will not resume
If you are running your notebook/Tablet
PC on battery power, be aware that the
battery continues to discharge while your
system is in Standby mode, though not as
fast as when fully operational.

HIBERNATE MODE

The Hibernate mode saves the contents of your
notebook/Tablet PC's system memory to the hard drive
as a part of the Suspend/Resume mode. Your system is
pre-configured 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. See "BIOS Setup Utility" on page 30.
■ 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
notebook/Tablet PC in Standby or
Hibernate mode. The resume function of
the button cannot be disabled.
■ If your notebook/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 trans-
ferred 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 re-
initialized when the system restarts.
■ The main advantage of using Hibernate
mode is that power is not required to
maintain your data. This is very impor-
tant if you will be leaving your system 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.
Using Hibernate Mode

DISPLAY TIMEOUT

The Video Timeout is one of the power management
parameters. This feature saves power by turning off the
display if there is no keyboard or pointer activity for the
user selected timeout period. Any keyboard or pointer
activity will cause the display to restart automatically.
This feature is independent of the Suspend/Resume
button and can be enabled and disabled in Windows
Power Management.

HARD DISK TIMEOUT

The Hard Disk Timeout is another one of the power
management parameters. This feature saves power by
turning off the hard drive if there is no hard drive
activity for the user selected timeout period. Any
attempt to access the hard drive will cause it to restart
automatically. This feature is independent of the
Suspend/Resume button and can be enabled and
disabled in Windows.

WINDOWS POWER MANAGEMENT

The Power Options icon located in the Windows
Control Panel allows you to configure some of the power
management settings. For example, you can use the
Power Options to set the timeout values for turning off
the display and hard disks whether you are running the
notebook/Tablet PC on battery power or one of the
adapters.
