LifeBook P7000 Notebook – Section Three
Power Management
Your Fujitsu LifeBook notebook has many options and
features for conserving battery power. Some of these
features are automatic and need no user intervention,
such as those for the internal modem. However, others
depend on the parameters you set to best suit your oper-
ating conditions, such as those for the display bright-
ness. Internal power management for your notebook
may be controlled from settings made in your operating
system, pre-bundled power management application, or
from settings made in BIOS setup utility.
Besides the options available for conserving battery
power, there are also some things that you can do to
prevent your battery from running down as quickly.
For example, you can create an appropriate power saving
profile, put your notebook into Standby mode when it
is not performing an operation, and you can limit the
use of high power devices. As with all mobile, battery
powered computers, there is a trade-off between
performance and power savings.
SUSPEND/RESUME/POWER ON BUTTON
When your LifeBook notebook is active, the Suspend/
Resume/Power On button can be used to manually put
your notebook into Standby mode. Push the button
when your notebook is active, but not actively accessing
anything, and immediately release the button. You will
hear two short beeps and your system will enter
Standby mode. (See figure 2-3 on page 6 for location)
If your LifeBook notebook is suspended, pushing the
Suspend/Resume/Power On button will return your
notebook to active operation. You can tell whether or
not your system is in Standby mode by looking at the
Power indicator. (See figure 2-3 on page 6) If the indi-
cator is visible and not flashing, your notebook is fully
operational. If the indicator is both visible and flashing,
your notebook is in Standby mode. If the indicator is not
visible at all, the power is off or your notebook is in
Hibernation mode.
ECO BUTTON
The ECO button is located to the left of the power
button above the keyboard. The button is designed to
extend system power by reducing the LCD brightness,
shutting down the optical drive, PC Card, and IEEE
1394 functionality, and enabling the hard disk drive’s
auto power off mode.
Press the ECO button, then click the [OK] button to
enter the power saving mode. Pressing the button again
then clicking the [OK] button restores those functions
STANDBY MODE
Suspend or Standby mode in Windows saves the
contents of your LifeBook notebook’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 notebook can be
put in Standby mode by:
■
Pressing the Suspend/Resume/Power On 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.
You can change the actions the computer takes when the
lid is closed or buttons are pressed by clicking [Start] ->
Control Panel. Double-click the Power Options icon and
select the Advanced tab.
Your LifeBook notebook’s system memory typically
stores the file(s) on which you are working, open applica-
tion(s) information, and any other data required to
support the operation(s) in progress. When you resume
operation from Standby mode, your notebook will
return to the point where it left off. You must use the
Suspend/Resume/Power On button to resume operation,
and there must be an adequate power source available, or
your notebook will not resume.
The ECO button can also be programmed
to be used as an application launch but-
ton. For more information, see “Configur-
ing the Application Panel” on page 18.
■
If you are running your notebook on
battery power, be aware that the
battery continues to discharge while the
system is in Standby mode, though not
as fast as when fully operational.
■
Disabling the Suspend/Resume/Power
On button prevents it from being used
to put your LifeBook notebook in
Standby or Hibernation (Save-to-Disk)
mode. The resume function of the
button cannot be disabled.
■
If your LifeBook notebook is actively
accessing information when you enter
the Standby or Hibernation 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 internal
hard drive during Hibernation mode.
