Power Management

Your 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 operating condi- tions, such as those for the display brightness. Internal power management for your LifeBook notebook may be controlled from settings made in your operating system.

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 Suspend 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.

POWER AND SUSPEND/RESUME BUTTON

When your LifeBook notebook is active, the Power and Suspend/Resume button can be used to manually put your notebook into Suspend mode. Push the Power and Suspend/Resume 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 Suspend mode.

If your notebook is suspended, pushing the Power and Suspend/Resume button will return your notebook to active operation. You can tell whether or not your system is in Suspend mode by looking at the Power indi- cator which is part of the Suspend/Resume button. (See Figure 2-8 on page 15 for location) If the indicator is visible and not flashing, your LifeBook notebook is fully operational. If the indicator is both visible and flashing, your notebook is in Suspend mode. If the indicator is not visible at all, the power is off or your notebook is in Save-to-Disk (Hibernation) mode. (See Hibernation (Save-to-disk) Feature on page 32 for more information)

SUSPEND MODE

Suspend or Standby mode 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 LifeBook notebook can be put in Suspend mode by:

■Pressing the Power/Suspend/Resume button when your system is turned on.

■Selecting Standby from the Windows Shut Down menu.

G e t t i n g S t a r t e d

■Timing out from lack of activity.

■Allowing the battery to reach the Dead Battery Warning condition.

Your LifeBook notebook’s system memory typically stores the file(s) on which you are working, open appli- cation(s) information, and any other data required to support the operation(s) in progress. When you resume operation from Suspend mode, your LifeBook notebook will return to the point where it left off. You must use the Power and Suspend/Resume button to resume opera- tion, and there must be an adequate power source avail- able, or your LifeBook notebook will not resume.

■If you are running your notebook on battery power, be aware that the battery continues to discharge while your note- book is in Suspend mode, though not as fast as when fully operational.

■Disabling the Suspend/Resume button prevents it from being used to put your LifeBook notebook in Suspend or Save- to-Disk mode. The resume function of the button cannot be disabled.

■The Suspend or Hibernation (Save-to- Disk) mode should not be used with cer- tain PC Cards. Check your PC Card doc- umentation for more information.

■When PC Cards or external devices are in use, Hibernation (Save-to-Disk) mode cannot return to the exact state prior to suspension because all of the peripheral devices will be re-initialized when the system re-starts.

■If your notebook is actively accessing information when you enter the Sus- pend or Hibernation (Save-to-Disk) mode, changes to open files are not lost. The files are left open and memory is kept active during Suspend mode, or the memory is transferred to the internal hard drive during Hibernation mode.

■The main advantage of using the Hiber- nation (Save-to-Disk) function is that power is not required to maintain your data. This is particularly important if you will be leaving your LifeBook notebook in a suspended state for a prolonged period of time. The drawback of using Hibernation mode is that it lengthens the power down and power up sequences and resets peripheral devices.

■Your system is set to use the Max Bat- tery power scheme when running on battery power. If you change the power scheme to a different profile, your bat- tery life may vary.
