7 HP PC Hardware Diagnostics To help troubleshoot and diagnose failures, use the UEFI-based hardware diagnostic solution that HP includes on all products. This tool can even be used if the computer will not boot to the operating system. Why run HP PC Hardware Diagnostics – UEFI The HP PC Hardware Diagnostic tools simplify the process of diagnosing hardware issues and expedite the support process when issues are found. The tools save time by pinpointing the component that needs to be replaced.
After pressing F2, the BIOS sequentially searches three places for the system diagnostics: a. First – a connected USB drive (to download the diagnostics tools to a USB drive, see the instructions in Downloading HP PC Hardware Diagnostics to a USB device on page 79). b. Second – the hard disk drive. c. Third – in the BIOS, a core set of diagnostics (for memory and hard disk drive) that are accessible only if the USB or hard disk drive versions are not detected.
8 Troubleshooting Without Diagnostics This chapter provides information on how to identify and correct minor problems, such as USB devices, hard drive, optical drive, graphics, audio, memory, and software problems. If you encounter problems with the computer, refer to the tables in this chapter for probable causes and recommended solutions.
● If you recently installed new software, uninstall the software and see if the computer functions properly. ● Boot the computer to the Safe Mode to see if it will boot without all of the drivers loaded.
