HP Dc7700 Testing on HP Business Desktop PCs - Page 4

• Automated Test Environment-This enables test teams to download a products software image, automatically install the software to replicate the manner in which a typical customer might install it, automatically run test scripts, and then log results into the database. For a given product configuration, hundreds of different software downloads, installations, and tests can be logged with minimal time and effort. • Quality Assurance-Software image development databases and tools enable a complete, end-toend, repeatable image test process. All HW, FW, and SW changes are systematically managed. System checks are in place to help make sure that what gets built in any factory worldwide and sent to the customer is the same as what was tested and qualified in engineering. Types of Testing HP executes a vast array of testing on Business Desktop PCs to help ensure that systems meet important industry standards. Multiple engineering teams conduct various types of testing throughout the product development cycle. This helps mitigate risk by providing needed checks and balances and it helps to ensure a high HP standard of quality. These tests include, but are not limited to: System Board Validation Testing This testing focuses on the signal quality of high-speed interfaces, power delivery to system components, and ACPI power management. The System board is put through stress testing to help ensure that it will operate normally while running a variety of applications. Testing includes: • Signal Integrity Testing-This helps ensure proper signal quality on all major interfaces on the system board including front-side bus, memory bus, system clocks, USB (universal serial bus), SATA, and PCI / PCI Express buses. • Voltage Integrity Testing-This helps ensure that voltage regulators on the system board and in the power supply remain within HP Business Desktop specifications while running stress level testing. Additionally, voltage stress testing is conducted and measured on the various supported memory and processor configurations. • Power Management Testing-This helps ensure that the system will go into and come out of all supported low-power states including S1, S3, S4, and S5. Additionally, power cycle testing is conducted to simulate many years worth of power-up/power-down usage with a minimum of 10,000 consecutive no-fail cycles. • Fan control-This helps ensure that the system fan(s) runs at required minimum thermal and acoustic levels for customers' needs. Platform Validation Testing This testing focuses on chipset validation, new architectural chipset features, the system board, processor, system memory, system BIOS, and system-level hardware interoperability to help ensure platform component stability prior to incorporation into an integrated desktop solution. Testing includes: • System BIOS Testing-This is comprehensive validation and qualification of the system BIOS. Testing includes BIOS calls and functionality, supported BIOS features, and expected BIOS interoperability with the platform hardware and software. • System Board-This is comprehensive validation and qualification of the system board (PCB/PCA) including testing of the chipset functionality/feature set, subsystem (i.e., CPU, Memory, Graphics, Audio, PCI/PCIE, NIC, USB, IDE, LPC, etc.), and associated hardware components. 4
