4 Routine 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. You must disconnect the power cord 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 that:
Dierent activities generate dierent amounts of static electricity.
Static electricity increases as humidity decreases.

16 Chapter 4 Routine care, SATA drive guidelines, and disassembly preparation

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 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 container.
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 exible straps with a maximum of one-megohm ± 10% resistance in the ground cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and t snugly into the banana plug connector on the grounding mat or workstation.
Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with most types of shoes or boots. On conductive oors or dissipative oor mats, use them on both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

Antistatic plastic
Carbon-loaded plastic
Metallized laminate

Grounding the work area

To prevent static damage at the work area, use the following precautions:
Cover the work surface with approved static-dissipative material. Provide 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 at static-free work areas.
Turn o power and input signals before inserting and removing connectors or test equipment.
1,500
7,500
15,000
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.
Electrostatic discharge information 17

Recommended materials and equipment

Materials and equipment that are recommended for use in preventing static electricity include:
Antistatic tape
Antistatic smocks, aprons, or sleeve protectors
Conductive bins and other assembly or soldering aids
Conductive foam
Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance
Static-dissipative table or oor mats with hard tie 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 display to permit the required airow.
Never restrict the airow 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 airow.
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 airow. Be sure to unplug the computer before cleaning the air vents.
Never operate the computer with the covers removed.
Keep liquids away from the computer and keyboard.
Install or enable power management functions of the operating system or other software, including sleep states.

Service considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.
18 Chapter 4 Routine care, SATA drive guidelines, and disassembly preparation

Tools and software requirements

To service the computer, you need the following:
Flat-bladed screwdriver
Non-marking, non-conductive pry tool
Phillips #2 screwdriver
Diagnostics software

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: Metric screws have a black nish. U.S. screws have a silver nish and are used on hard drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area
to prevent damage.

Cables and connectors

Most cables used throughout the unit are at, exible 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 CPU.
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. For more information about preventing electrostatic damage, refer to
Electrostatic discharge information on page 16
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 displays or speakers.
Service considerations 19

Lithium coin cell battery

The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime of about three years.
See the appropriate removal and replacement chapter for the chassis you are working on in this guide for instructions on the replacement procedures.

Operating guidelines and routine care

Follow the guidelines below to properly set up and care for the system:
HP recommends a 17 mm clearance around the vents on the mobility head unit and I/O connectivity base for heat dissipation.
Keep the system away from excessive moisture, direct sunlight, and extremes of heat and cold.
Never operate the system with any access panels removed.
Do not stack systems on top of each other or place them so near each other that they are subject to each other’s recirculated or preheated air.
If the system 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 still apply.
Keep liquids away from the mobility system and I/O connectivity base.
Never cover the vents on the mobility system or I/O connectivity base with any type of material.
Install or enable power management functions of the operating system or other software, including sleep states.
Turn o the mobility system before you do either of the following:
Wipe the exterior with a soft, damp cloth as necessary. Using cleaning products may discolor or damage the nish.
Occasionally clean the air vents on all vented sides of the mobility system. Lint, dust, and other foreign matter can block the vents and limit the airow.
NOTE: For more information on your retail system care and maintenance, refer to “Retail Point of Sales
Systems - Routine Care and Maintenance” available at http://www.hp.com/support.

Touch screen maintenance

Keep your display and touch sensor clean. The touch sensor requires very little maintenance. HP recommends that you periodically clean the glass touch sensor surface. Be sure to turn o your display before cleaning. Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch

sensor. It is important to avoid using any caustic chemicals on the touch sensor. Do not use any vinegar-based solutions.
Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. Always dampen the cloth and then clean the sensor. Be sure to spray the cleaning liquid onto the cloth, not the sensor, so that drips do not seep inside the display or stain the bezel.

MSR maintenance

To clean the MSR (magnetic stripe reader), swipe a standard cleaning card through the MSR a couple of times. You can order a standard cleaning card online. You can also put a thin oil-free cloth around a credit card.

Cleaning the printer

Because of the way the printer sits while in use, it is likely there is a buildup of paper and other debris from the knife. HP recommends that you keep the printer in working order by periodically cleaning the debris from the printer.
To clean the printer, open the cover, remove the paper roll, and then use a can of compressed air to blow the debris out from the bottom plate where it accumulates.

Cleaning I/O ports

The mobility system has a series of ports. Dust and debris can collect in these ports, which can reduce connectivity and performance. Use a battery-powered vacuum to remove any debris that has accumulated in and around these ports.
Updating drivers and rmware
HP recommends that you regularly download and install the latest drivers and rmware updates to help enhance system performance, resolve known issues, and avoid replacing parts unnecessarily.
Go to http://www.hp.com/support to download and install the latest drivers and BIOS updates for your specic Retail Point of Sale model.
