HP Support Assistant

HP Support Assistant is an application that helps you maintain the performance of your computer and resolve problems through automated updates and tune-ups, built-in diagnostics, and guided assistance. HP Support Assistant is preinstalled on all HP or Compaq computers with Windows 7.

To access HP Support Assistant in Windows 7, double-click the HP Support Assistant icon on your desktop.

Using HP PC Hardware Diagnostics

If HP Support Assistant is unable to detect a problem, try the UEFI-based hardware diagnostic solution that HP includes on all products. You can use this tool even if the computer will not boot to the operating system. This tool also works with components not diagnosed in HPSA.

Why run HP PC Hardware Diagnostics

The HP PC Hardware Diagnostic tools simplify the process of diagnosing hardware issues and expedite the support process when issues are found. The tools save time by pinpointing the component that needs to be replaced.

●Isolate true hardware failures: The diagnostics run outside of the operating system so they effectively isolate hardware failures from issues that may be caused by the operating system or other software components.

●Failure ID: When a failure is detected that requires hardware replacement, a 24-digit Failure ID is generated. This ID can then be provided to the call agent, who will either schedule support or provide replacement parts.
