Managing Power
Your computer has power management capability so you can
reduce the amount of energy used, especially during periods
of inactivity. Effective use of power management options
can greatly conserve and extend your battery life. The power
management unit monitors system activity, such as hard drive,
keyboard, mouse, or any devices attached to a port. If it does
not detect activity for a period of time, the computer stops
some or all of these devices in order to conserve energy.
Your computer employs a power management scheme that
supports ACPI (Advanced Configuration and Power Interface),
allowing for maximum power conservation and maximum
performance at the same time. Windows
®
handles all power-
saving chores for your computer.

Windows

Low-Power States
Your computer can enter three different low-power states to
conserve power: Standby/Sleep, Hibernate and Power Off.
These states can be entered manually or after a period of
inactivity. From the Power Saver or DynaPower utilities, you
can configure the
POWER BUTTON, SLEEP BUTTON (FN+F3)
and
LID SWITCH to initiate any of the low-power states.
Standby/Sleep
Most system devices are powered off, but the contents of
system memory are retained. Standby/Sleep is sometimes
referred to as Suspend to RAM. When the computer returns
from Standby mode, the desktop appears with the same files
and programs open as when the computer was suspended.
