	The diagnostics utility enables you to perform testing and to view critical computer hardware and
	software configuration information from various sources. This utility enables you to:
	Run diagnostics
	iew the hardware configuration of the system
	Key features and benefits
	HP Insight Diagnostics simplifies the process of effectively identifying, diagnosing, and isolating the
	hardware issues. In addition to robust management tools, service tools can be invaluable in quickly
	resolving system problems. To streamline the service process and resolve problems quickly, it is necessary
	to have the right information available at the time that a service call is placed. The primary information
	requirement, which is also the one that provides the greatest insight into potential system issues, is the
	configuration of the system. Insight Diagnostics helps provide higher system availability. Typical uses of
	the Insight Diagnostics are:
	Testing and diagnosing apparent hardware failures
	Documenting system configurations for upgrade planning, standardization, inventory tracking,
	disaster recovery, and maintenance
	Sending configuration information to another location for more in-depth analysis
