Using The Power Management Features - Epson ActionNote 650 User Manual

Using the Power Management Features

Your ActionNote offers a variety of automatic and manual
power management features to help you conserve battery and
electrical power. These features slow down or stop the
operation of various system component—such as the CPU, the
hard disk, and the LCD screen—when you are not using your
computer but are leaving the power on.
There are four levels of power-savings that your computer can
enter: two standby modes and two suspend modes. Each of the
four modes provides progressively increased power
conservation and affects the functioning of progressively more
components in your computer.
The standby modes—CPU Standby and Global Standby—
reduce the speed and performance of the CPU, components
related to CPU operations, and peripheral components such as
the hard disk and LCD screen.
The suspend modes, Suspend to Memory and Suspend to Disk,
cut off power to the CPU and many other components to
provide the maximum power savings.
Caution
Read "Using Suspend to Disk Mode" on page 3-16 before
using Suspend to Disk mode so you can configure the
computer correctly for it.
