Fault notification and recovery
Fault notification and recovery features combine innovative hardware and software technology to
prevent the loss of critical data and minimize unplanned downtime.
If the workstation is connected to a network that is managed by HP CMS, the workstation sends a fault
notice to the network management application. With HP CMS, you can also remotely schedule
diagnostics to run on managed PCs and create a summary report of failed tests.

Dual-state power button
With ACPI enabled, the power button can function as an on/off switch or as a sleep state button. This
feature does not completely turn off power, but instead causes the workstation to enter a low-power
standby state. This enables you to go to standby without closing applications, and to return to the same
operational state without any data loss.
Changing the power button configuration
To change the power button configuration:
1.Select Start, and then select Control Panel>Power...

Warnings and cautions
WARNING! Any surface or area of the equipment marked with this symbol indicates the presence
of a hot surface or hot component. If this surface is contacted, the potential for injury exists. To reduce
the risk of injury from a hot component, enable the surface to cool before touching.
WARNING! Any surface or area of the equipment marked with this symbol indicates the presence
of an electrical shock hazard. To reduce the risk of injury from electrical shock, do not open any enclosed...

Service considerations
Review the following service considerations before replacing system components.
Cautions, warnings and safety precautions
Review the cautions, warnings, and safety precautions before accessing the workstation components.
Also, review the Safety and Regulatory Guide that came with the workstation for more information.
ESD information
Generating static
The following table shows that different activities generate different amounts of static electricity through
electrostatic discharge...

Preventing ESD equipment damage
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree
of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to
electric components and accessories:
●Transport products in static-safe containers such as tubes, bags, or boxes, to avoid hand contact.
●Protect electrostatic parts and assemblies with nonconductive or approved containers or
packaging.
●Keep electrostatic-sensitive parts in...

Grounding the work area
To prevent static damage in the work area:
●Cover the work surface with approved static-dissipative material. Use a wrist strap connected to
the work surface, and properly grounded tools and equipment.
●Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●Handle electrostatic-sensitive components, parts, and assemblies by the case or PCB laminate.
Handle them only in static-free work areas.
●Disconnect power and input signals before inserting and...

Tools and software requirements
The tools necessary for workstation component removal and installation are:
●Torx T-15 driver
●Flat blade and cross-tip screwdrivers
●Diagnostics software
Special handling of components
The components included in this section require special handling when servicing the workstation.
WARNING!Do not use the front bezel as a handle or lifting point when lifting or moving the workstation.
Lifting the workstation from the front bezel, or lifting it incorrectly, could cause the...

Hard drives
Hard drives are fragile, precision components. Avoid subjecting them to physical shock and vibration.
The following guidelines apply to all drives, including failed drives, replacement drives, and spares.
●Do not remove hard drives from the shipping package for storage. Keep hard drives in their
protective packaging until they are mounted in the workstation.
●Avoid dropping hard drives from any height.
●If you are inserting or removing a hard drive, power off the workstation. Do not remove a...
