How does ACPI handle power management during system boot?
During system boot, the BIOS or UEFI firmware initializes hardware components, including the ACPI tables stored in the system's firmware.
ACPI tables provide information about the system's hardware configuration and power management capabilities.
The ACPI BIOS initializes the ACPI subsystem, which includes loading ACPI drivers and interpreting ACPI tables.
ACPI uses the information from ACPI tables to configure power management features such as sleep states (e.g., S1, S3), CPU power states (C-states), and other hardware-specific power-saving features.
ACPI collaborates with the operating system's power management features to control device power states, optimize energy usage, and manage system resources effectively.
