FRU Replacement Strategy

Before Replacing Parts

Ensure that all software fixes are installed prior to replacing any FRUs listed in this manual.

Use the following strategy to prevent unnecessary FRU replacement and service expense:

If you are instructed to replace a FRU and that does not correct the problem, reinstall the original FRU before you continue.

Some computers have both a processor board and a mainboard. If you are instructed to replace either the processor board or the mainboard, and the first board that you replaced does not correct the problem, reinstall the original board, and then replace the other (processor or system) board.

If an adapter or device consists of more than one FRU, an error code may be caused by any of the FRUs. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the faulty FRU.

Safety Notice 5

Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel.

Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la mise à la masse d'une batterie peut produire suffisamment de courant pour brûler des matériaux combustibles ou causer des brûlures corporelles graves.

Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu entzünden oder Verletzungen bei Personen hervorzurufen.

Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto circuito o a massa può fornire corrente sufficiente da bruciare materiali combustibili 0 provocare ustioni al tecnici di manutenzione.

Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada o con contacto a tierra puede producir la corriente suficiente como para quemar material combustible o provocar quemaduras en el personal.

Safety Notice 6

Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, then disconnect any interconnecting cables.

Avant de retirer une unité remplaçable en clièntele, mettez le système hors tension, débranchez tous les cordons d'alimentation des socles de prise de courant, retirez la batterie et déconnectez tous les cordons d'interface.

Die Stromzufuhr muß abgeschaltet, alle Stromkabel aus der Steckdose gezogen, der Akku entfernt und alle Verbindungskabel abgenommen sein, bevor eine FRU entfernt wird.

Safety Information

The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer.

General Safety

Follow these rules to ensure general safety:

Observe good housekeeping in the area of the machines during and after maintenance.

When lifting any heavy object:

1.Ensure you can stand safely without slipping.

2.Distribute the weight of the object equally between your feet.

3.Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4.Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

Before you start the machine, ensure that other service representatives and the customer’s personnel are not in a hazardous position.

Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.

Keep your tool case away from walk areas so that other people will not trip over it.

Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.

Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Attention: Metal objects are good electrical conductors.

Wear safety glasses when you are: hammering, drilling, soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

Reinstall all covers correctly before returning the machine to the customer.

xiiIBM WorkPad z50, Mobile Companion xii

Electrical Safety

Observe the following rules when working on electrical equipment.

Important

Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

Do not work alone under hazardous conditions or near equipment that has hazardous voltages. Disconnect all power before:

-Performing a mechanical inspection

-Working near power supplies

-Removing or installing main units

Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

If you need to work on a machine that has exposed electrical circuits, observe the following precautions:

-Ensure that another person, familiar with the power-off controls, is near you.

Attention: Another person must be there to switch off the power, if necessary.

-Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back.

Attention: There must be a complete circuit to cause electrical shock. By observing the above rule, you may prevent a current from passing through your body.

-When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.

-Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

© Copyright IBM Corp. 1998

xiii

Regularly inspect and maintain your electrical hand tools for safe operational condition.

Do not use worn or broken tools and testers.

Never assume that power has been disconnected from a circuit. First, check that it has been poweredoff.

Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage.

Do not service the following parts with the power on when they are removed from their normal operating places in a machine:

-Power supply units

-Pumps

-Blowers and fans

-Motor generators

and similar units. (This practice ensures correct grounding of the units.)

If an electrical accident occurs:

-Use caution; do not become a victim yourself.

-Switch off power.

-Send another person to get medical aid while first aid is being administered.

Safety Inspection Guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock)

Explosive hazards, such as a damaged CRT face or bulging capacitor

Mechanical hazards, such as loose or missing hardware

xivIBM WorkPad z50, Mobile Companion xiv

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1.Check exterior covers for damage (loose, broken, or sharp edges).

2.Power-off the computer. Disconnect the power cord.

3.Check the power cord for:

a.A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

b.The power cord should be the appropriate type as specified in the parts listings.

c.Insulation must not be frayed or worn.

4.Remove the cover.

5.Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6.Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

7.Check for worn, frayed, or pinched cables.

8.Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling Electrostatic

Discharge-Sensitive Devices

Any computer part containing transistors or integrated circuits (Ics) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes

1.Use product-specific ESD procedures when they exceed the requirements noted here.

2.Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

Keep the parts in protective packages until they are inserted into the product.

Avoid contact with other people.

Wear a grounded wrist strap against your skin to eliminate static on your body. Approved static straps protect the user from high-operating voltages (110V).

Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.

Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices. Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement.

Note

The use of a grounding system is desirable but not required to protect against ESD damage.

-Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

-Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

-Use the round ground-prong of the AC plug on AC-operated computers.

Grounding Requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

WorkPad z50 Mobile Companion (2608)

Read This First

Before you go to the checkout guide, be sure to read this section.

Important

Only certified trained personnel should service the computer.

Read FRU service procedures before replacing any FRUs.

Replace FRUs only for the correct model.

When you replace the FRU, make sure the model of the machine and FRU part number are correct by referring to the parts list.

FRUs should not be replaced because of a single, unreproducible failure. Single failures can occur from a variety of reasons that have nothing to do with a hardware problem, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. If this is suspected, clear the log error and run the test again. Do not replace any FRUs if log errors do not appear.

Be careful not to replace a nondefective FRU.

Torque Driver

If you have a torque driver, refer to the “Torque” instruction with each step.

Cradle Problems: If you suspect a problem with the cradle, see “Cradle Checkout” on page 15.

How to Diagnose Multiple FRUs: When the

adapter or the device has more than one FRU, the error code could be caused by any of them. Before replacing multiple FRUs, try removing or exchanging each FRU, one by one in the designated sequence, to see if the symptoms change.

2 IBM WorkPad z50, Mobile Companion 2

Attention

Pushing the WorkPad z50’s Power button will power on (or resume) the system, or put the system in suspend mode: there is no power-off state.

If the AC Adapter, battery pack, and backup battery are removed, the system is reset and all the stored data is lost. There is no lithium battery to retain memory while these power sources are removed.

What to Do First: The service personnel must fill in the following information in the parts exchange form or parts return form that is attached to the returned FRU:

__ 1 Name and phone number of service personnel __ 2 Date of service

__ 3 Date when the part failed __ 4 Date of purchase

__ 5 Failure symptoms, error codes appearing on the monitor, and beep symptoms

__ 6 Procedure index and page number in which the failing FRU was detected

__ 7 Failing FRU name and part number

__ 8 Machine type, model number, and serial number __ 9 Customer’s name and address

Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following:

During the warranty period, the customer may be responsible for repair costs if the computer damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer. The following list provides some common items that are not covered under warranty and some symptoms that may indicate that the system was subjected to stress beyond normal use:

The following is not covered under warranty:

LCD panel cracked from the application of excessive force or from being dropped.

Scratched (cosmetic) parts

Cracked or broken plastic parts, broken latches, broken pins, or broken connectors caused by excessive force

Damage caused by liquid spilled into the system

Checking Operational Charging: There is no difference in

battery charging time whether the system is fully operational or not. To check the battery charging, use a discharged battery pack or a battery pack that has less than 50% of total power remaining.

Turn on the WorkPad z50 while the AC Adapter is connected to the system. The External Power/Charge Status LED will change to amber while the battery is charging. When the battery is fully charged (after about 1 – 2.5 hrs., depending on the battery’s initial charge) the battery terminal voltage should be around 12.6V dc. If the voltage is far less, or has not increased from the initial voltage, then repeat the procedure with another discharged battery pack. If this brings the same result, then suspect a mainboard failure.

Optional Dry Cell Battery Checkout: If the optional Dry

Cell Kit (dry cell battery pack) has a problem, refer to the following:

1.Enter suspend mode by pressing the Power button.

2.Remove the dry cell battery pack and measure the voltage between the battery terminals. See the following figure:

If the dry cell battery pack is extremely hot, it must be replaced.

12 IBM WorkPad z50, Mobile Companion 12

Backup Battery Checkout (Nonrechargeable)

If removing all power sources except for the backup battery results in the system being reset, suspect a problem with the backup batteries. Refer to the following:

1.Enter suspend mode by pressing the Power button.

2.Remove the AAA batteries and measure the voltage between the battery terminals. The voltage should be 1.1–1.6 V dc per battery.

If the voltage is correct, replace the mainboard.

If the voltage is less than 1.1 V dc per battery, then the batteries have been discharged. Replace the batteries.

If the backup battery discharges quickly after replacement, replace the mainboard.

Note: Make sure either the battery pack is installed or the AC Adapter is connected. If the backup batteries are removed and no other power source is available (AC Adapter or battery pack), the system is reset, and all the stored data is lost.

The Battery Calibration Application

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists.

When analyzing the intermittent problem, do the following:

1.Run the diagnostic test for the mainboard in loop mode.

2.If no error is detected, do not replace any FRUs.

3.If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist.

Undetermined Problems

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs).

Verify that all attached devices are supported by the WorkPad z50.

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power Systems Checkout” on page 9.)

1.Enter suspend mode.

2.Visually check them for damage. If any problems are found, replace the FRU.

3.Remove or disconnect all of the following devices:

a.Non-IBM devices

b.Devices attached to the cradle

c.External devices

d.Battery pack

e.DRAM

f.PC Cards

g.Compact Flash Cards

The arrows in the “Removals and Replacements” section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal.

When other FRUs must be removed before the failing FRU is removed, they are listed at the top of the page.

To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement.

When replacing a FRU, use the correct screw size as shown in the procedures.

Safety Notice 1: Translation on page viii

Before the WorkPad z50 is powered-on after FRU replacement, make sure all screws, springs, or other small parts are in place and are not left loose inside the WorkPad z50. Verify this by shaking the WorkPad z50 and listening for rattling sounds. Metallic parts or metal flakes can cause electrical shorts.

Safety Notice 2: Translation on page ix

The battery pack contains small amounts of harmful substances. Do not disassemble it, throw it into fire or water, or short-circuit it. Dispose of the battery pack or backup battery as required by local ordinances or regulations. Use only the battery in the appropriate parts listing when replacing the battery pack. Use of an incorrect battery can result in ignition or explosion of the battery.

Safety Notice 6: Translation on page xi

Before removing any FRU, place the WorkPad z50 into suspend mode, unplug all power cords from electrical outlets, then disconnect any interconnecting cables and remove the battery pack and backup batteries.

CAUTION:

If all power sources are removed from the WorkPad z50, all data and applications will be lost. If the problem is considered a software problem stored on DRAM memory, approach the problem from that standpoint before removing all power sources.

Attention: The mainboard is sensitive to, and can be damaged by, electrostatic discharge.

30 IBM WorkPad z50, Mobile Companion 30

An electrostatic discharge (ESD) strap (P/N 6405959) must be used to establish personal grounding.
