Power Management

Your Fujitsu LIFEBOOK Tablet PC has many options and features for conserving battery power. Some

of these features are automatic and need no user intervention. 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 Tablet PC 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 Tablet PC into Sleep 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/Suspend/Resume Switch

When your Tablet PC is active, the Power/Suspend/Resume switch can be used to manually put the Tablet

PC into Sleep mode. Push the Power/Suspend/Resume switch when the Tablet PC is active, but not

actively accessing anything, and immediately release the button.

If your Tablet PC is suspended, pushing the Power/Suspend/Resume switch returns it to active operation.

You can tell whether the system is Suspended by looking at the Power indicator. If the indicator is visible

and not flashing, your Tablet PC is fully operational. If the indicator is visible and flashing, the Tablet PC

is in Sleep mode. If the indicator is not visible, the power is off or your Tablet PC is in Hibernation mode.

Sleep Mode

Sleep mode in Windows saves the contents of your system memory during periods of inactivity by

maintaining power to critical parts. This mode turns off the CPU, display, hard drive, and all other internal

components except those necessary to maintain system memory and for restarting.

Your Tablet PC can be put in sleep mode by:

• Pressing the Power/Suspend/Resume switch when your system is turned on.
