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 operating conditions, such as those for the display brightness. 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 indicator 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. The ECO button can also be programmed to be used as an application launch button. For more information, see "Configuring the Application Panel" on page 18. 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 application(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. ■ 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. 30
