The HP BIOS extensive Power-On Self Test (POST) provides exhaustive error messages to inform the user or administrator when a computer failure has been detected. The POST is a series of diagnostic tests that execute when the HP Business Desktop computer is turned on. If an error is detected, the error notification displayed contains a brief problem description and recommended action, in most cases. Typically, HP Business Desktop computers are configured to execute a reduced set of POST tests to increase boot speed during normal power cycles. However, if a computer has been experiencing difficulty or the customer environment demands more stringent test requirements, F10 setup provides configurable levels of POST testing. The full complement of POST tests can be set to execute on every boot or once every 1 to 30 days. In addition, computer health information can be viewed by a system administrator using HP Client Manager Software (see http://h18019.www1.hp.com/im/?jumpid=re_R2515_VAcontent/PSG/en_intelligentmanageability for more information). Networked computers using HP Insight Manager, HP Client Manager, or other system management application can receive alerts for most error conditions from HP Business Desktop computers. 15
