Using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unied 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.
NOTE: To start Setup Utility, your computer must be in notebook mode and you must use the keyboard
attached to your tablet. The on-screen keyboard, which displays in tablet mode, cannot access Setup Utility.
To start HP PC Hardware Diagnostics (UEFI):
1. Start Setup Utility:
●
Computers or tablets with keyboards:
▲
Turn on or restart the computer, quickly press esc.
●
Tablets without keyboards:
▲
Turn on or restart the tablet, and then quickly hold down the volume down button.
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
