Hardware diagnostic tests

HP Advanced System Diagnostics provides five sets of hardware diagnostic tests to validate the functionality of hardware components (including the CPU, memory, graphics, and system board) prior to booting the operating system.

If the operating system cannot load because of a hardware failure, the diagnostics can be used to determine which hardware component has failed.

In the case of system failure, the diagnostics generate a unique 24–digit Failure ID code to identify the specific components that did not pass validation.

Test	Function
Start-Up	Analyzes the main components to make sure they are functioning properly to start the computer, the processor
Test	(CPU), the memory modules, and the hard drive. It checks the SMART attributes of the hard drive and
	performs the built-in Self-Test.
Run-In Test	Repeats the Start-up Test and checks for intermittent problems that the start-up test does not detect. Use this test
	if the computer is having intermittent problems while running, that do not appear to be related to system
	startup.
System	Similar to the Start-Up Test, the System Tune-Up performs the Start-Up Test plus tests the video memory.
Tune-Up
Hard Disk	The Hard Disk Test allows the selection of the Quick Extensive Test or Extensive Test of user selected drives in
Test	the system. The user can select a single drive, or they can select all of the drives in the system to run
	concurrently. The tests consists of the following subtests:
	●	Quick Test
		◦	Hard Disk SMART Check
		◦	Hard Disk Short DST
	●	Extensive Test
		◦	Hard Disk SMART Check
		◦	Hard Disk Short DST
		◦	Hard Disk Optimized DST Check
		◦	Hard Disk Long DST
Memory	Analyzes the physical condition of the memory modules and reports any faulty modules. If this test reports an
Test	error, the faulty memory module(s) should be replaced immediately.

The Memory Test allows selection of the Quick Memory Test or Extensive Memory Test.

The Quick Test is the same version run in the Start-Up Test, and takes around five minutes for 4GB of memory to complete.

The Extensive Test runs a longer version of the Memory Test, which adds additional pattern and transfer types to make it a more comprehensive test of the memory. This test normally runs approximately eight minutes/GB. Test times varies depending on system architecture, processor speed, and amount of memory.
