Hardware Diagnostic Tests - HP Z220 SFF Maintenance And Service Manual

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.

Function
Analyzes the main components to make sure they are functioning properly to start the computer, the processor
(CPU), the memory modules, and the hard drive. It checks the SMART attributes of the hard drive and
performs the built-in Self-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.
Similar to the Start-Up Test, the System Tune-Up performs the Start-Up Test plus tests the video memory.
The Hard Disk Test allows the selection of the Quick Extensive Test or Extensive Test of user selected drives in
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
◦
Analyzes the physical condition of the memory modules and reports any faulty modules. If this test reports an
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.
