HP Notebook PCs - Testing for Hardware Failures (Windows 7, Vista)

This document pertains to HP Notebook PCs with Windows 7 or Windows Vista.
HP PC Diagnostics UEFI or the HP System Diagnostics provides access to a comprehensive set of tests to check for hardware failures. These diagnostics are accessed by pressing the F2 key while the computer is starting. HP Support Assistant is accessed from Windows and includes a more limited set of hardware diagnostics tests.
Checking for the latest updates
The UEFI System Diagnostic is available on most HP notebook PCs, manufactured after late-2008. An updated BIOS might be available for your computer. Go to the Software Drivers and Downloads page for more information.
Updated UEFI System Diagnostics might also be available for your computer. To download the latest version, go to the HP Hardware Diagnostics UEFI website.
Many issues with HP Support Assistant can be resolved by downloading and installing the latest version of HP Support Assistant from the HP Support Assistant home site.
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 HP PC Hardware Diagnostics UEFI even if the computer does not open to Windows. Follow these steps to run the hardware diagnostics tests:
  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, until you see one of the following screens:
If this screen is displayed, continue with UEFI System and Component Testing.
If this screen is displayed, see Basic hardware diagnostics tests.
If this screen is displayed, see Testing using HP System Diagnostics.
UEFI System Tests
 note:
If your HP PC Hardware Diagnostics UEFI is older than the version used here, you can upgrade it to the latest version. For the latest software version and installation instructions, go to the HP Hardware Diagnostics UEFI website.

Testing using HP System Diagnostics
HP System Diagnostics is a program built into the BIOS of your computer and is a quick and easy way to identify basic computer hardware problems. Since it is built into the BIOS, HP System Diagnostics can be opened even when you cannot open the computer to Windows.
 note:
Some computers that came with Windows Vista may not have HP System Diagnostics.
Testing using HP Support Assistant in Windows 7 or Vista
HP Support Assistant provides easy access to several hardware diagnostic tests. This section describes how to test for hardware problems with HP Support Assistant Diagnostics.
 note:
Many issues with HP Support Assistant can be resolved by downloading and installing the latest version of HP Support Assistant from the HP Support Assistant home site (in English).
HP Support Assistant can be used only if the computer boots into Windows. If the computer does not boot into Windows, use the UEFI.
The hard drive test in HP Support Assistant has been removed because of its inability to test in RAID and eSATA environments. To test the hard drive, restart the computer and perform the test from the UEFI environment. See the Component Tests in UEFI.
