HP PC Hardware Diagnostics UEFI (Version 1.6.1.0) is a powerful pre-boot diagnostic environment built directly into the firmware of HP computers. Its standout feature is the ability to perform deep hardware validation outside the Windows operating system
F2 key (for most consumer HP laptops/desktops) or the Esc key (to enter the Startup Menu, then select F2).| Test Category | Components Tested | BIOS Dependence | |---------------|------------------|----------------| | System Board | Chipset, USB controllers, fan speeds, temperature sensors | High – uses SMBus and LPC via BIOS | | Memory | All RAM modules (pattern tests, MATS++) | Medium – BIOS provides memory map | | Storage | HDD/SSD (SMART, short/long DST, random seek) | Low – direct ATA commands | | CPU | All cores, cache, floating-point, stress test | High – uses CPU µcode from BIOS | | Video | GPU memory, 2D/3D render (optional) | Medium – requires GOP driver from BIOS | | Network | LAN controller, loopback test | Low – uses NIC’s UEFI driver | hp pc hardware diagnostics uefi version 1610 bios work
