Power Management; Power/Suspend/Resume Button; Sleep Mode - Fujitsu LifeBook T900 User Manual

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 Button

When your Tablet PC is active, the Power/Suspend/Resume button can be used to manually put the Tablet
PC into Sleep mode. Push the Power/Suspend/Resume button 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 button returns your Tablet PC 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, your 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.
