3Routine care, SATA drive guidelines, and disassembly preparation

This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service.

CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. The power cord must be disconnected from the power source before opening the computer to prevent system board or component damage.

Electrostatic discharge information

A sudden discharge of static electricity from your nger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be a ected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in

the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.

Generating static

The following table shows how humidity a ects the electrostatic voltage levels generated by di erent activities. A product can be degraded by 700 volts.

● Di erent activities generate di erent amounts of static electricity.

●Static electricity increases as humidity decreases.

	Relative Humidity
Event	55%	40%	10%
Walking across carpet	7,500 V	15,000 V	35,000 V
Walking across vinyl floor	3,000 V	5,000 V	12,000 V
Motions of bench worker	400 V	800 V	6,000 V
Removing DIPs from plastic tube	400 V	700 V	2,000 V
Removing DIPs from vinyl tray	2,000 V	4,000 V	11,500 V
Removing DIPs from Styrofoam	3,500 V	5,000 V	14,500 V
Removing bubble pack from PCB	7,000 V	20,000 V	26,500 V
Packing PCBs in foam-lined box	5,000 V	11,000 V	21,000 V

Electrostatic discharge information

Preventing electrostatic damage to equipment

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.

●To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.

●Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging.

●Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.

●Place items on a grounded surface before removing them from their containers.

●Always be properly grounded when touching a sensitive component or assembly.

●Avoid contact with pins, leads, or circuitry.

●Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.

Personal grounding methods and equipment

Use the following equipment to prevent static electricity damage to equipment:

●Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords. To provide proper ground, a strap must be worn snugly against bare skin. The ground cord must be

connected to the banana plug connector on the grounding mat or workstation and t snugly into it.

●Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

	Static Shielding Protection Levels
Method	Voltage
Antistatic plastic	1,500
Carbon-loaded plastic	7,500
Metallized laminate	15,000

Grounding the work area

To prevent static damage at the work area, observe the following precautions:

●Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and use 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 at static-free work areas.

●Turn o power and input signals before inserting and removing connectors or test equipment.

● Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.

●Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.

●	Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

10 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

Recommended materials and equipment

The following grounding equipment is recommended to prevent electrostatic damage:

●Antistatic tape

●Antistatic smocks, aprons, or sleeve protectors

●Conductive bins and other assembly or soldering aids

●Conductive foam

●Conductive tabletop workstations with ground cords of one-megohm +/- 10% resistance

●Static-dissipative table or floor mats with hard ties to ground

●Field service kits

●Static awareness labels

●Wrist straps and footwear straps providing one-megohm +/- 10% resistance

●Material handling packages

●Conductive plastic bags

●Conductive plastic tubes

●Conductive tote boxes

●Opaque shielding bags

●Transparent metallized shielding bags

●Transparent shielding tubes

Operating guidelines

To prevent overheating and to help prolong the life of the computer:

●Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.

●Operate the computer on a sturdy, level surface. Leave a 10.2 cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow.

●Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place

the keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also restricts airflow.

●Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning the air vents.

●Never operate the computer with the cover or side panel removed.

●Do not stack computers on top of each other or place computers so near each other that they are subject to each other’s re-circulated or preheated air.

●If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the enclosure, and the same operating guidelines listed above will still apply.

●Keep liquids away from the computer and keyboard.

Operating guidelines 11

●Never cover the ventilation slots on the monitor with any type of material.

●Install or enable power management functions of the operating system or other software, including sleep states.

Routine care

General cleaning safety precautions

1.Never use solvents or flammable solutions to clean the computer.

2.Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component.

3.Always unplug the computer when cleaning with liquids or damp cloths.

4.Always unplug the computer before cleaning the keyboard, mouse, or air vents.

5.Disconnect the keyboard before cleaning it.

6.Wear safety glasses equipped with side shields when cleaning the keyboard.

Cleaning the computer case

Follow all safety precautions in General cleaning safety precautions on page 12 before cleaning the computer.

To clean the computer case, follow the procedures described below:

●To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.

●For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping the surface with a cloth or swab dampened with clear water.

●For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed; alcohol will evaporate quickly without leaving a residue.

●After cleaning, always wipe the unit with a clean, lint-free cloth.

●Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airflow.

Cleaning the keyboard

Follow all safety precautions in General cleaning safety precautions on page 12 before cleaning the keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer case on page 12.

When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 12 before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.

●Visible debris underneath or between the keys may be removed by vacuuming or shaking.

●Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys.

12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

●If you want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronics supply outlets.

CAUTION: Never remove a wide, level key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly.

●Cleaning under a key may be done with a swab moistened with isopropyl alcohol and then squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any

bers or dirt in con ned areas. Allow the parts to air dry before reassembly.

Cleaning the monitor

●Wipe the monitor screen with a towelette designed for cleaning monitors or with a clean cloth moistened with water. Do not use sprays or aerosols directly on the screen; the liquid may seep into the housing and damage a component. Never use solvents or flammable liquids on the monitor.

●To clean the monitor body follow the procedures in Cleaning the computer case on page 12.

Service considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.

Tools and software requirements

To service the computer, you need the following:

●Diagnostics software

●Flat-bladed screwdriver (may sometimes be used in place of a Torx screwdriver)

●Phillips #2 screwdriver

Screws

The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of di erent lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.

CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.

Service considerations

13

Cables and connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.

CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can damage the computer.

Hard Drives

Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares.

●If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.”

●Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are actually mounted in the computer.

●Avoid dropping drives from any height onto any surface.

●	If you are inserting or removing a hard drive, turn o the computer. Do not remove a hard drive while
	the computer is on or in standby mode.

●Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector.

●Do not use excessive force when inserting a drive.

●	Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic elds
	such as CRT monitors or speakers.
