3-6 Managing Power
Power Management
Your computer supports ACPI (Advanced Configuration and Power Interface) for power
management. The power management feature allows you to reduce the power
consumption for saving energy.
With an ACPI-compliant operating system such as Windows XP and Windows Vista,
power supply to different computer components is controlled on an as-needed basis.
This allows maximum power conservation and performance at the same time.
In general, Windows’ power management works in this way:
What… When…
Power to the hard disk is turned
off When the hard disk has been idle
for a set period.
Power to the display is turned off When the display has been idle for
a set period.
When the entire system has been
idle for a set period.
When you press Fn+F10. *
When you close the cover. *
The computer enters Standby
mode. The hard disk and display
are turned off and the entire
system consumes less power.
When you press the power button. *
When you press the power button. *
When you press Fn+F10. *
The computer enters Hibernation
mode. (See the next subsection
for more information.)
When you close the cover. *
*
depends on your Windows settings.
For detailed information on power management, see Windows’ Help. Power
management settings should not be completely disabled. Generally, users will not see
significant benefit by setting hard drive shutdown times of longer than a few minutes.
When ML910 RUGGED NOTEBOOK is intended for in-vehicle use, it is recommended
that hard drive power down should be set to 1 minute to prevent premature wear-out of
the hard-drive.
CAUTION:
Do not disable power management if the laptop will be used in extreme temperatures
or high vibration environments (e.g., vehicles).
Hibernation
When you use the hibernation feature, you do not have to close the applications and
documents that are running on the computer. The computer stores the state of your
computer to a file on the hard disk before shutting down. The next time you turn on your
computer, you return to exactly where you left off.
