3.6 Hardware Management Subsystem

3.6.1 Fanless Thermal Solution

The chassis is required to be fanless, thermally and environmentally robust in lower air-quality

environments (i.e., dust, 40°C ambience, etc.). Bravo will not be used outdoors.

Fan-less thermal solution meets these requirements:

• The chassis and thermal solution need to be designed so all system configurations do not

exceed 70C skin temp at 35C ambient.

• We can exceed 70C skin temperature at higher ambience. The ODM must perform testing

at 40C and 50C for respective configurations to inform ASUS of the max skin temp

observed under the PRD defined workloads.

• Warning labels and or notifications is provided to customers if skin temps exceed 80C

under ambient conditions > 35C.

3.6.2 System States and Power States

Table 14 describes the ACPI states supported by the processor.

3.6.2.1 Wake-up Devices and Events

Lists devices or specific events that can wake the computer from specific states.

Bravo Canyon must support the wake-up events listed below. Note that S4 implies OS support only.

NOTE

The use of these wake-up events from an ACPI state requires an operating system that provides full

ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events.
