Acpi; Sleeping State - Motorola Mobile Workstation 520 Application Developer's Manual

ACPI

Sleeping State

The MW-520 supports ACPI for Windows 98/2000/Me, using a standard ACPI
system with a number of extensions:
• At state S4, power is preserved for most devices.
At state S5 the power is Off.
• Battery handling is similar to standard battery handling, providing a battery low
notification. However, in case of a "Low" event, the battery power level is set to
100% or 5%.
• The MW-520 includes three temperature sensors designed to protect the system
from overheating and causing the CPU to throttle. If the temperature rises above
the determined "Suspend" level, the system is suspended (see below for more
details).
