Using HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unified 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.

To start HP PC Hardware Diagnostics UEFI:

1.Turn on or restart the computer, quickly press esc, or hold down the volume down button while the “Hold the Volume Down button to enter the BIOS Startup Menu” is displayed at the bottom of the screen. The Startup menu is displayed.

2.Press or tap 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 81.

b.Hard drive

c.BIOS

3.When the diagnostic tool opens, use the keyboard arrow keys or the touch screen to 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 or tap anywhere on the touch screen.
