Removal and Replacement

Preliminaries

This chapter provides essential information for proper and safe removal and replacement service.

4.1 Tools Required

You will need the following tools to complete the removal and replacement procedures:

■

■

■

■

Magnetic screwdriver

Phillips P0 screwdriver

Torx8 T8 screwdriver

Flat-bladed screwdriver



4–1

Removal and Replacement Preliminaries

4.2 Service Considerations

The following sections include some of the considerations that you should keep in mind during disassembly and assembly procedures.

✎

As you remove each subassembly from the tablet PC, place the subassembly (and all accompanying screws) away from the work area to prevent damage.

Plastic Parts

Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts.

Apply pressure only at the points designated in the maintenance instructions.

Cables and Connectors

Ä

CAUTION: When servicing the tablet PC, make sure cables are placed in their proper locations during the reassembly process.

Improper cable placement can damage the tablet PC.

Cables must be handled with extreme care to avoid damage.

Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Make sure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables tear easily.

4–2




4.3 Preventing Damage to

Removable Drives

■

■

■

■

Removable drives are fragile components that must be handled with care. To prevent damage to the tablet PC, damage to a removable drive, or loss of information, observe the following precautions:

■

Before removing or inserting a hard drive, shut down the tablet PC. If you are unsure whether the tablet PC is off or in hibernation, turn the tablet PC on, and then shut it down through the operating system.

■

■

■

Before removing a diskette drive or optical drive, make sure that a diskette or disc is not in the drive and make sure that the optical drive tray is closed.

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

Handle drives on surfaces covered with at least one inch of shock-proof foam.

Avoid dropping drives from any height onto any surface.

■

After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag.

Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers.

Avoid exposing a drive to temperature extremes or liquids.

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



4–3


4.4 Preventing Electrostatic Damage

Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. 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.

A sudden discharge of static electricity from a finger 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 may not be affected at all and can work perfectly throughout a normal cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life expectancy.

4–4




4.5 Packaging and Transporting

Precautions

Use the following grounding precautions when packaging and transporting equipment:

■

■

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 the parts arrive at static-free workstations.

■

■

■

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

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

Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam.

■

Use transporters and conveyors made of antistatic belts and roller bushings. Make sure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.



4–5


4.6 Workstation Precautions

■

■

Use the following grounding precautions at workstations:

■

Cover the workstation with approved static-shielding material

(refer to Table 4-2, “Static-Shielding Materials”

).

■

Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment.

■

Use conductive field service tools such as cutters, drivers, and vacuums.

■

When fixtures must directly contact dissipative surfaces, use fixtures made only of static-safe materials.

■

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

■

Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items only at static-free workstations.

Avoid contact with pins, leads, or circuitry.

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

4–6




4.7 Grounding Equipment and

Methods

Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.

■

When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times.

On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap.

■

When standing, use foot straps and a grounded floor mat.

Foot straps (heel, toe, or 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 foot straps on both feet with a minimum of one megohm resistance between the operator and ground. To be effective, the conductive strips must be worn in contact with the skin.

■

■

■

■

■

■

Other grounding equipment recommended for use in preventing electrostatic damage includes:

■

■

■

■

■

Antistatic tape

Antistatic smocks, aprons, and sleeve protectors

Conductive bins and other assembly or soldering aids

Nonconductive foam

Conductive tabletop workstations with ground cords of one megohm resistance

■

Static-dissipative tables or floor mats with hard ties to the ground

Field service kits

Static awareness labels

Material-handling packages

Nonconductive plastic bags, tubes, or boxes

Metal tote boxes

Electrostatic voltage levels and protective materials

Software Backup and

Recovery

Backup

HP Backup and Recovery Manager provides several ways to back up the system and to recover optimal system functionality.

✎

HP installed drivers, utilities, and applications can be copied to a CD or to a DVD using HP Backup and Recovery Manager.

✎

Formatted DVD±RW discs and DVD±RW double-layer discs are not compatible with HP Backup and Recovery Manager.

✎

The computer must be connected to external power before you perform backup and recovery procedures.

Safeguarding Your Data

To safeguard your documents, store personal files in the My

Documents folder and periodically create a backup copy of the folder.



B–1

Software Backup and Recovery

Backing Up the System

Using HP Backup and Restore Manager, you can

■

■

■

Back up specific files and folders.

Back up the entire system.

Back up modifications since your last backup, using

HP system restore points.

■

B–2




Backing Up the Entire Hard Drive

When you perform a complete backup of the hard drive, you are saving the full factory image, including the Windows operating system, software applications, and all personal files and folders.

✎

A copy of the entire hard drive image can be stored on another hard drive, on a network drive, or on recovery discs that you create.

✎

This process may take over an hour, depending on your computer speed and the amount of data being stored.

To back up your entire hard drive:



2. Click Next.

8. Click Next.




B–3


Backing Up Modifications Made to the

System

When you back up modifications since your last backup, you are creating system recovery points. This allows you to save a snapshot of your hard drive at a specific point in time. You can then recover back to that point if you want to reverse subsequent changes made to your system.

✎

The first system recovery point, a snapshot of the entire image, is automatically created the first time you perform a backup.

Subsequent recovery points make a copy of changes made after that time.

HP recommends that you create recovery points

■

■

Before you add or extensively modify software or hardware.

Periodically, whenever the system is performing optimally.

✎

Recovering to an earlier recovery point does not affect data files or e-mails created since that recovery point.

After you create a recovery point, you are prompted to schedule subsequent recovery points. You can schedule recovery points for a specific time or event in your system.

To create and schedule a system recovery point:



2. Click Next.



4. Click Create or manage Recovery Points, and then click

Next.

A summary of your system recovery point settings is displayed.


Recovery

HP Backup and Recovery Manager analyzes the hard drive and creates a dedicated hard drive recovery partition on the hard drive large enough to store a copy of the full factory image. You can choose whether you want to store that copy on the recovery partition, on another drive, or on external recovery discs.

✎

Before using HP Backup and Recovery Manager, try repairing the system by running Microsoft Windows System Restore.

For more information, select Start > Help and Support, and then search for “System Restore.”

HP Backup and Recovery Manager allows you to

■

Create recovery discs (highly recommended). The recovery discs are used to start up your computer and to recover the full factory image (operating system and software) in case of system failure or instability.



B–5


✎

If you do not have a CD or DVD burner, a copy of the entire hard drive image can be stored on another hard drive or on a network drive.

■

Perform a recovery. You can perform a full system recovery or recover important files from the recovery partition on the hard drive, from another drive, or from recovery discs that you create.

Creating Recovery Discs

(Highly Recommended)

After setting up the computer for the first time, you can create a set of recovery discs of the full factory image, using Recovery

Media Creator in the HP Backup and Recovery Manager. The recovery discs are used to start up (boot) the computer and recover the operating system and software to factory settings in case of system failure or instability.

Ä

CAUTION: After you create the recovery discs, you can increase the amount of available space on the hard drive by deleting the recovery partition. However, doing this is not recommended. If you delete this partition, you will lose any information that is on the partition.

✎

Only one set of recovery discs can be created for this computer.

Before creating recovery discs:

■
