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.

The BIOS searches three places for the diagnostic tools, in the following order:

a. Connected USB drive

NOTE: To download the HP PC Hardware Diagnostics (UEFI) tool to a USB drive, see Downloading HP

PC Hardware Diagnostics (UEFI) to a USB device on page 98.

b. Hard drive

c. BIOS

3. When the diagnostic tool opens, select the type of diagnostic test you want to run, and then follow the on-

screen instructions.

NOTE: If you need to stop a diagnostic test, press esc.
