Power States and Targeted System Power Global States Sleeping States Processor States G0 – working state S0 – working C0 – working D0 – working state. Full power > 30 W G1 – sleeping state S1 – Processor stopped C1 – stop grant D1, D2, D3 – device specification specific. 5 W < power < 52.5 W G1 – sleeping state S3 – Suspend to RAM. Context saved to RAM. No power D3 – no power except for wake-up logic.
Product Description ✏ 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. 1.13.2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply.
Intel Desktop Board D845GVSR Technical Product Specification 1.13.2.1 Power Connector ATX12V-, SFX12V-, and TFX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off).
Product Description 1.13.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface.

Intel Desktop Board D845GVSR Technical Product Specification 2.10 Mechanical Considerations The Desktop Board D845GVSR is designed to fit into either a microATX or an ATX-form-factor chassis. Figure 11 illustrates the mechanical form factor for the Desktop Board. Dimensions are given in inches [millimeters]. The outer dimensions are 9.20 inches by 8.20 inches [233.68 millimeters by 208.28 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification.
Technical Reference 2.10.1 I/O Shield The back panel I/O shield for the Desktop Board D845GVSR must meet specific dimension and material requirements. Systems based on this Desktop Board need the back panel I/O shield to pass emissions (EMI) certification testing. Figure 12 shows the critical dimensions of the I/O shield. Dimensions are given in inches [millimeters], to a tolerance of ±0.020 inches [0.508 millimeters]. The figures also indicate the position of each cutout.
Intel Desktop Board D845GVSR Technical Product Specification 2.11 Electrical Considerations 2.11.1 DC Loading Table 37 lists the DC loading characteristics of the board. This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw.
Technical Reference 2.11.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. System integrators should refer to the power usage values listed in Table 37 when selecting a power supply for use with the Desktop Board D845GVSR.
Intel Desktop Board D845GVSR Technical Product Specification CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area o (item A in Figure 13) can reach a temperature of up to 85 C in an open chassis. Figure 13 shows the locations of the localized high temperature zones.
Technical Reference 2.13 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using component and subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBF prediction is used to estimate repair rates and spare parts requirements. The MTBF data is calculated from predicted data at 55 ºC. The Desktop Board D845GVSR MTBF is 149979.68 hours. 2.

Intel Desktop Board D845GVSR Technical Product Specification Table 70. BIOS Error Messages (continued) Error Message Explanation Checking NVRAM..... NVRAM is being checked to see if it is valid. Update OK! NVRAM was invalid and has been updated. Updated Failed NVRAM was invalid but was unable to be updated. Keyboard Error Error in the keyboard connection. Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed.
Error Messages and Beep Codes 5.2 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
