9 Using HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unied Extensible Firmware Interface (UEFI) that allows you to run diagnostic

tests to determine whether the computer hardware is functioning properly. The tool runs outside the

operating system so that it can isolate hardware failures from issues that are caused by the operating system

or other software components.

When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit

Failure ID is generated. This ID can then be provided to support to help determine how to correct the problem.

To start HP PC Hardware Diagnostics (UEFI), follow these steps:

1. Turn on or restart the computer, and quickly press esc

2. Press F2.
