PUTTING HP BUSINESS PCs TO THE TEST The HP Total Test Process encompasses tests across a wide range of measures. These include tests that stress system components, notebook lids and displays, keyboards, optical drives, hard drives, and electrical features. We also subject our business PCs to drop and shock testing, thermal and vibration testing, system integration testing, and more. Consider the following examples of our Total Test Process. System components Our test professionals exert an immense amount of stress on processors, host bus, memory subsystem, chipset and peripherals. These exercises verify the standard third-party devices on systems using the operating system's or vendor's drivers. By using custom peripheral test cards and drivers, the test also confirms that other bus transactions occur correctly. The benefit to our customers is enhanced overall notebook reliability to help reduce system issues, downtime, failures and repairs. Keyboards To make sure your HP keyboard is ready for the demands you place on it, we employ mechanical tests to simulate seven years of keyboard usage or to validate mechanical, electrical and cosmetic properties. That's an amazing 20 million keystrokes on our business keyboards. Environmental testing Notebook PCs are subject to the rigors and environmental conditions that come with security checkpoints, overhead luggage compartments and frequent exposure to outdoor climates. Desktop PCs might be put into service on open-air shipping and receiving docks, construction trailers and manufacturing floors filled with vibrating machinery. To make sure our business PCs are ready for these challenges, we subject our products to extreme temperature and humidity conditions, simulating operation in harsh environments. For example, we test the fans in HP Business Desktops in temperatures exceeding 150 degrees Fahrenheit (65.6 degrees Celsius). At the system level, HP tests our PCs under extreme thermal and vibration conditions. These tests give us insights that help us build high levels of reliability into every HP Business Desktop and Notebook PC. While not embraced by all manufacturers in the industry, HP remains committed to completing this type of testing to deliver a more reliable notebook. Notebook lids and displays In HP Business Notebook PCs, we apply rigorous testing procedures to all aspects of the display assembly, including hinges, clutches, latches, the enclosure and scratch-resistant surfaces. To make sure HP Business Notebooks are ready for the challenges of daily wear and tear, we employ mechanical tests to simulate opening and closing the notebook 10 times every day for six years or 25,000 cycles. To deliver more durable display panels, we use scuff testing to help ensure display surface hardness and scratch resistance. Batteries To stay productive, business travelers rely on dependable batteries on their notebooks. They also have high expectations for ever-increasing battery runtimes to take them through their workdays. To deliver on these expectations, we put our notebook batteries through extensive quality testing. Battery cells are first tested individually, then tested again after they are assembled into battery packs and then re-tested with the batteries placed in-system. Cells are charged at different rates and under different environmental conditions. The process can take up to a year before they meet HP standards. Optical drives We subject HP Business Desktop PCs to tests that repeatedly eject and retract motorized optical drives for 15,000 ODD open and close cycles to help ensure their reliability. We're that detailed to help ensure your business PCs last.
