The CMOS battery maintains the Real-Time Clock (RTC) and BIOS settings.

The Super I/O sends a signal (often called PWRBTN_OUT# ) to the PCH, telling it the user wants to boot. desktop motherboard power sequence pdf exclusive
Pressing the button sends a signal to the SIO. The SIO then relays a "Power Button Out" signal to the South Bridge. SLP_S4 / SLP_S3: The CMOS battery maintains the Real-Time Clock (RTC)
The guide meticulously breaks down the startup process into sequential, verifiable steps: desktop motherboard power sequence pdf exclusive
Power is then supplied to components like RAM (DDR voltage), PCH, and finally the CPU Core voltage (VCORE) via the VRM section. Power Good Signals:
