HP Notebook PCs - Testing for Hardware Failures (Windows 10, 8)

This information applies to HP and Compaq notebook computers with Windows 10 and Windows 8.
HP provides diagnostic software that you can use to test hardware components on your computer; to confirm hardware failures when you suspect something is wrong.
HP provides two ways to access the testing software: HP PC Diagnostics UEFI at startup or through the HP Support Assistant software in Windows.
  • Use HP PC Diagnostics UEFI as the preferred method for testing hardware and when Windows 8 does not start.
  • Use HP Support Assistant for convenience in Windows. Not all tests are supported from HP Support Assistant.
Installing the latest version of HP PC Hardware Diagnostics (UEFI)
HP occasionally makes updates to its HP PC Hardware Diagnostics (UEFI) environment. For steps to find the latest version, go to About UEFI and the Startup Menu. You can install UEFI to a blank FAT or FAT32 formatted USB drive to use when the main storage device fails or when the UEFI files are corrupted. UEFI can be accessed from a USB drive by disabling Secure Boot.
  1. Download the latest version of UEFI, and then select Run.
    The InstallShield Wizard opens.
  2. Click Next.

Testing using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics (UEFI) enables you to test the main components on your computer using quick tests or longer, more comprehensive tests. You can use UEFI even if the computer does not open to Windows. Follow these steps to run the hardware diagnostics tests:
If you have accessed UEFI from a USB drive, skip to the System Tests section.
  1. Hold the power button for at least five seconds to turn off the computer.
  2. Turn on the computer and immediately press the F2 key repeatedly, about once every second.
  3. The HP PC Hardware Diagnostics (UEFI) home page displays.

If your HP PC Hardware Diagnostics (UEFI) is older than the version used here, you can upgrade it to the latest version. For information on UEFI and installation instructions for the latest version, go to About UEFI and the Startup Menu.
The HP PC Hardware Diagnostics (UEFI) main menu has system information, tests, and test logs. The steps in this section describe how to run the tests and view the test logs. Use one of the following tests to check for hardware failures:
Testing from an external USB device (UEFI)
In the event UEFI is unable to load the extended tests from the hard drive, a properly prepared USB device can be used to boot the PC into an extended testing environment. To prepare a USB device, download and install the latest version of HP PC Hardware Diagnostics (UEFI).
  1. Turn off the computer.
  2. Insert the USB drive containing the latest UEFI version into a USB port on the computer.
  3. Press the power button. Press the Esc key repeatedly until the Startup Menu screen appears.
    If you cannot start the computer from the USB storage device, temporarily disable Secure Boot from the BIOS. For instructions to disable Secure Boot, go to Secure Boot (Windows 8).
  4. Press F2 to select System Diagnostics.
