Using Power Management; Doze; Suspend And Resume; Lcd Idle - EUROCOM 7200 User Manual

Using Power Management

The Notebook system provides you with various modes to manage its power
consumption while maintaining system performance. Refer to Chapter 3: WINBIOS
Setup on how to set the options.

Doze

Doze mode is the state in which the CPU is fully alive and operational, yet running at
a speed that is greatly reduced in order to save power. The system may enter the Doze
mode when there is no system activity for a specified period of time.
Suspe nd and Resume
The system offers the ability to halt operations at extremely low power yet retain all
its programming, called Suspend . The Suspend Mode features two levels: 5 V-
Suspend -Mode (referred to as Suspend-to-DRAM) and 0V-Suspend-Mode (referred to
as Suspend-to-Disk). 5 V-Suspend -Mode will respond to interrupt events to determine
a return to normal operation, called Resume.

LCD Idle

The system will shut off the Notebook's LCD display panel backlight after a specified
period of time of display inactivity. The display panel backlight will be turned back
on once there is any input to the Notebook or any output from the Notebook.

Hard Disk Idle

The system will turn off the Notebook's hard disk drive motor if it has not been
accessed after a specified period of time. The motor will be turned back on once the
system attempts to read or write data to it.
Advanced Power Management (APM 1.2)
The Notebook provides built-in Advanced Power Management (APM 1.2) support to
reduce power consumption. The functionality of APM varies depending on the
operating system you are using. Some operating systems do not support APM, such as
Windows NT, and therefore, cannot take advantage of the system's capabilities in this
area.
