HP PC Hardware Diagnostics
To help troubleshoot and diagnose failures, use the UEFI-based hardware diagnostic solution that HP includes
on all products. This tool can even be used if the computer will not boot to the operating system.
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.
How to access and run HP PC Hardware Diagnostics
