Overview and Specifications
Overview
1.1.1.6 CPU Fan Auto-Off in Sleep (Doze) Mode
The CPU fan activates whenever power is turned on. It continues to operate when
the system enters
Standby
mode. When in
Sleep
mode, the CPU will not run at
full power, hence generating less heat. Sleep settings are made through the PC
health-monitor utility.
1.1.1.7 CPU Overheat LED and Control
This feature is enabled by the user through the CPU overheat warning function in the
BIOS. With it, the user can define an overheat temperature that, when exceeded,
activates the overheat fan and the
Overheat
warning LED.
1.1.1.8 System Resource Alert (
optional
)
Available only through Intel’s LANDesk Client Manager (an
optional
third-party
product), this feature is used to notify the user of certain system events. For example,
if the system is running low on virtual memory and there is insufficient disk-drive
space for saving the data, an alert will be issued warning of the potential problem.
1.1.1.9 Auto-Switching Voltage Regulator
The auto-switching voltage regulator for the CPU core can support up to 20A of cur-
rent and auto-sense voltage IDs ranging from 1.4V to 3.5V. This allows the regulator
to run cooler, making the system more stable.
1.1.2
ACPI Features
Advanced Configuration and Power Interface or ACPI defines a flexible and abstract
hardware interface that provides a standard method of integrating power manage-
ment features throughout the system. This includes hardware, the operating system,
and application software. As a result, the system can automatically turn peripherals
(CD-ROMs, NICs, hard-disk drives, and printers, for example) on or off, including
any consumer devices that may be connected to the system (VCRs, TVs, telephones,
and stereo systems, for example).
In addition to providing operating-system power management, ACPI offers a generic
system event mechanism for Plug and Play and an operating-system-independent
interface for configuration control. Plug-and-Play BIOS data structures are lever-
aged, while the implementation is processor-architecture-independent and compati-
ble with both Windows 2000 and Windows NT 5.0.
