11 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
You can run the diagnostics from one of three places, depending on your preference and the health of
the computer.
1. Turn on the computer and press Esc repeatedly until the BIOS Boot Menu appears.
2. Press F2 or select Diagnostics (F2).
Pressing F2 signals the system to search for the diagnostics in the following locations:
a. A connected USB drive (to download the diagnostics tools to a USB drive, see the instructions
in
Downloading HP PC Hardware Diagnostics to a USB device on page 208)
b. The hard disk drive
c. A core set of diagnostics in the BIOS (for memory and hard disk drive) that are accessible
only if the USB or hard disk drive versions are not detected
