HP PC Hardware Diagnostics

Summary

HP PC Hardware Diagnostics is a set of tools for testing computer components and identifying hardware failures. The Windows application runs within Windows 10 or 11, while UEFI diagnostics runs outside the operating system to help identify and isolate problems. Listed tests cover processor, memory, storage, power, audio, Bluetooth, fan, keyboard, mouse or touchpad, network, and video; available tests vary with installed components. The Windows tool also offers driver checks and updates for select components, and HP says it comes pre-installed on new HP computers or can be downloaded from its diagnostics page or the Microsoft Store. If Windows cannot start, UEFI diagnostics can be launched from the F2 startup menu or run from a USB flash drive. Diagnostics can generate a 24-digit failure ID to use with the product number when starting a repair process. HP says UEFI tests are intended for genuine HP hardware and does not guarantee they will work on other manufacturers’ products. The software is free. The Windows memory Quick Test is not currently available.
