technical support personnel to view information about the hardware configuration of the computer and
perform hardware troubleshooting on HP Desktop and Workstation systems. This diagnostic tool should
be used to help determine hardware failures. Accessible by either CD or USB key, these diagnostics
run outside the operating system and so make it easy to isolate potential issues that may be operating
system related versus hardware.
