Power Management
Your 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 LIFEBOOK Tablet
PC 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
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.
In Windows 7, when you have a second battery installed you can select the battery discharge settings by going to
Start -> Battery Utility -> Battery Discharge Settings.
Power and Suspend/Resume Slide
When your Tablet PC is active, the Power and Suspend/Resume slide can be used to manually put it into Sleep mode.
Push the Power and Suspend/Resume slide when your Tablet PC is active, but not actively accessing anything, and
immediately release the slide. Your system will enter Sleep mode.
If your Tablet PC is suspended, pushing the Power and Suspend/Resume slide will return your Tablet PC to active
operation. You can tell whether or not your system is in Sleep mode by looking at the Power indicator which is part
of the Suspend/Resume slide.
(See figure 2 on page 11 for location)
If the indicator is visible and not flashing, your
LIFEBOOK Tablet PC is fully operational. If the indicator is both visible and flashing, your Tablet PC is in Sleep mode.
If the indicator is not visible at all, the power is off or your Tablet PC is in Save-to-Disk (Hibernation) mode.
See
“Hibernation (Save-to-Disk) Feature” on page 67.
Sleep Mode
Sleep mode saves your Tablet PC’s system memory contents 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 Tablet PC can be put in Sleep mode by:
• Pressing the Power/Suspend/Resume slide when your system is turned on.
