For a detailed definition of the system behavior within each Sx state, refer to ACPI specification section 7.5.2. For a detailed definition of the transitions between each of the Sx states, refer to ACPI specification section 9.1. S1 Sleeping State: The S1 sleeping state is a low wake-up latency sleeping state.

Software Functional Overview Active, Passive, and Critical Policies There are three primary cooling policies that the OS uses to control the thermal state of the hardware. The policies are Active, Passive and Critical: − − − Passive cooling: The OS reduces the power consumption of the system to reduce the thermal output of the machine by slowing the processor clock. The _PSV control method is used to declare the temperature to start passive cooling.
Software Functional Overview 1. The OS notifies the hardware of the new cooling mode by running the Set Cooling Policy (_SCP) control method. 2. When the hardware receives the notification, it can set a new temperature for both cooling policies and notify the OS that the thermal zone policy temperatures have changed. 3. The OS re-evaluates _PSV and _ACx.
Software Functional Overview 3.5.13 Hardware Thermal Events An ACPI-compatible OS expects the hardware to generate a thermal event notification through the use of the SCI. When the OS receives the SCI event, it will run the _TMP control method to evaluate the current temperature. Then the OS will compare the value to the cooling policy temperatures.
Software Functional Overview 3.5.15 Passive Cooling Equation Temperature Unlike the case for _ACx, during passive cooling the OS takes the initiative to actively monitor the temperature in order to cool the platform. On an ACPI-compatible platform that properly implements CPU throttling, the temperature transitions will be similar to the following figure.
Software Functional Overview Before disabling power, platform designers should incorporate some time that allows the OS to run its critical shutdown operation. There is no requirement for a minimum shutdown operation window that commences immediately after the temperature reaches _CRT. This is because − − Heat might rise rapidly in some systems and slower on others, depending on casing design and environmental factors.
Software Functional Overview Object Description _ACx Returns Active trip point in tenths Kelvin _ALx List of pointers to active cooling device objects _CRT Returns critical trip point in tenths Kelvin _PSL List of pointers to passive cooling device objects _PSV Returns Passive trip point in tenths Kelvin _SCP Sets user cooling policy (Active or Passive) _TC1 Thermal constant for Passive cooling _TC2 Thermal constant for Passive cooling _TMP Returns current temperature in tenths Kelvin _T
Software Functional Overview _PSV This control method returns the temperature at which the OS must activate CPU throttling. Arguments: None. Result Code: Temperature in tenths Kelvin. The result code is an integer value that describes up to 0.1 precision in Kelvin. For example, 300.0 Kelvin is represented by 3000. _SCP This control method notifies the hardware of the current user cooling mode setting. The hardware can use this as a trigger to reassign _ACx and _PSV temperatures.
Software Functional Overview 3.5.19 AC Adapters and Power Source Objects The Power Source objects describe the power source used to run the system. Object Description _PSR Returns present power source device _PCL List of pointers to powered devices. _PSR Returns the current power source devices. Used for the AC adapter and is located under the AC adapter object in name space. Used to determine if system is running off the AC adapter.

Troubleshooting and Repair Table 6-3 (d) BIOS Beep Codes Beep Code Diagnostic 4-2-3 36h Gate A20 failure. To test extended memory, the processor must be placed in protected mode and the A20 line must be enabled. For the memory tests, the BIOS generally uses the keyboard controller to enable A20. If the A20 line is not properly set during the memory test, an error message is displayed on the screen and the memory test are suspended. The system does not halt.
