FRU Replacement Strategy

Before Replacing Parts

Ensure t h at all s oftware f i xes ar e i ns t all ed pr i or t o replacing any FRUs listed in this manual.

Use the follow ing strategy to preve nt unnecessary FR U replac em ent and ser vice expense:

•

If you are instructed to replace a FRU and that

does not correct the problem, reinstall the original FRU before you continue.

•

Some compu t ers have bot h a proc es sor board and a

mainb oard . If you are instruc t ed t o rep lace either the processor board or the mainboard, and the first board that you replaced does not correct the problem, reinst all t h e original board, and then repl ac e th e ot h er (processor or s ystem) boar d.

•

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.

machines durin g and after maint en ance.

•

When lifti ng an y h ea vy objec t:

1. Ensure you can stand safely without slipping.

2. Distribut e the weight of t h e obj ec t eq u all y between you r f eet.

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

cust omer, or th at m ak es t h e equi p m ent unsafe.

•

Before you st art th e m ac hi n e, ens ur e t h at oth er

servic e represen t atives and the custom er ’s personnel are not in a haz ar d ous pos ition.

•

Place remov ed c over s an d other parts in a safe

place, away from al l 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 roll ed 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 f or you r cl othing.

Attention: Metal obj ec ts ar e go od el ec t rical conductors.

•

Electrical Safety

Obser ve th e f ollow i ng rules wh en w orking on el ectrical equipm en t.

Importa nt

Use only ap proved tool s and t est equ ip m ent. Some han d tools hav e h and l es c ov ered with a soft m at er i al that does not insulate you when working with live electrical currents.

Many customers hav e, near th eir equip m ent, ru bb er f l oor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect you rself from electrical shoc k.

•

Find the room emergency power-off (EPO) switch,

disconnectin g s witch, or elect r ical outl et. If an electrical acci d ent occurs, you c an th en operate th e 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:

- Perf ormin g a m ec hanical ins pecti on

- Working near power supplies

- Removi ng or ins t all i n g m ain units

•

Before you start to work on the machine, unplug the

power cord. If you cannot unplug it, ask the customer to pow er-off the wall box that su pplies power to the machine and to lock the wall box in th e off position.

•

If you need to wor k on a m ach ine that h as

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 han d w h en w ork ing with powered-on electrical equipment; keep the other hand in your poc k et or behind your bac k.

Attention: There mus t be a comp l ete cir cuit to cause electrical shock. By observing the above rule, you may prevent a current from passi ng through your body.

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

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

Obser ve th e sp ec i al s afety prec autions wh en y ou work with very high vol t ages; thes e ins tructions are in the saf ety s ections of mainten ance inform ation. Use extrem e c ar e wh en me as ur i ng hi g h vol tages.

xiv IBM WorkPad z50, Mobile Companion xiv

•

Regularly inspect and maintain your electrical hand

tools for s afe operati onal condition.

•

Do not use worn or broken tools and testers.

•

Never assume

that p ow er has been disconnec ted

from a circuit. First,

check

that it has been powered-

off.

•

Always look carefully for possible hazards in your

work area. Exam ples of th es e haz ards are m ois t floors, nongrounded power extension cables, power surges, and m is s ing safet y grou nds.

•

Do not touch li ve el ec tr ical circ uits w it h the reflect ive

surfac e of a plas t ic d ent al mirror. The surfac e is conductive; such touching can cause personal injury and machine damage.

•

Do not service the following parts

with the power on

when they are remov ed f rom their norm al operatin g pla ces in a mach ine:

- 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 ins p ect i on guide is to assis t you in identifying potentially unsafe conditions on these products. Each mac hi n e, as it w as des igned and built, had r equ ir ed safety items installed to protect users and service personnel from injury. This guide addresses only those items. However , g ood ju dg m ent shoul d b e us ed to id entif y poten tial safety h az ar ds du e t o att ac hment of n on- IBM featu res 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

voltag e on the frame c an c ause serious or fatal electrical shock)

•

Explosive hazards, such as a damaged CRT face or

bulging capacitor

•

Mecha nical hazards, such as loose or missing

hardware

The guid e cons is ts of a s eries of steps present ed 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 ed ges).

2. Power-off the computer. Disconnect the power

cord.

3. Check the power cord for:

a. A third-wire ground connector in good

conditi on . Us e a met er to m eas ure third-wire ground c ontinuit y f or 0. 1 ohm or less b et w een the external grou nd pi n and fram e ground.

b. The power cord should be the appropriate type

as specifi ed in th e p arts lis t in gs .

c. Insul at ion must n ot b e fr ayed or worn .

4. Remove the cover.

5. Check for any obvi ous non-IBM alterations. Use

good judg m en t as to t h e s af et y of an y n on- IBM alterations.

6. Check inside the unit for any obvious unsafe

conditi ons , suc h as metal filin gs , c ontamination, water or other liq ui ds , or si gns of f ir e or sm ok e d am ag e.

7. Check for worn, fraye d, 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 char g e b etw een objects. Protect agai ns t E SD damage by equalizing the charge so tha t the machine, the part, th e wor k m at, an d t h e person handling th e part ar e all at the same charge.

Notes

1. Use product-specific ESD procedures when they

exceed th e req ui rements noted her e.

2. Make sure that the ESD protective devices you

use have been certified (ISO 9000) as fully effective.

When hand li ng ESD-s ens it ive parts :

•

Keep the parts in protective packages until they are

inserted into the product.

•

Avoid contact with other people.

•

Wear a ground ed wris t strap agains t your skin t o

eliminate static on your body. Approved static straps protect t h e us er f r om hig h-oper at in g vol tages (1 10V ) .

•

Prevent the part from touching your clothing. Most

clothing is insulative and retains a charge even when you are we ari ng a wrist str ap.

•

Use the black side of a grounded w or k m at to provid e

a static-free work surface. The mat is especially useful when handling ESD-sensit i ve devices. S el ect a groundi ng s ys tem, suc h as th os e lis ted below , t o provid e pr ot ection th at m eets t h e sp ecif ic service requir em en t.

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 br aid, or green-wir e ground.

- Use an ESD common ground or reference point wh en working on a dou bl e- i ns ul ated or batter y- op erated s yst em . You c an us e c oax or connector-out s id e sh el ls on t h es e s yst ems .

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

Grounding Requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outl et c an be verifi ed by a c ertified el ectr ic ian.

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 compu ter .

•

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 mach in e and FRU p art nu m b er ar e c orr ec t 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 reas ons that have nothing to do with a hardware problem, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered onl y wh en a recur r in g problem exis ts . If this is suspected, clear the log error and run the test agai n. Do n ot r epl ace any FRUs if log errors do not appear.

•

Be careful not to replace a nondefective FRU.

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 anal yz i ng t h e int ermitt ent problem , d o th e f oll ow in g:

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 exi s t.

Undetermined Problems

You are here because the diagnostic tests did not identify which adap ter or devic e failed, ins t al led devices are incorrect, a short circuit is suspected, or the system is inoper at i ve. Follow these procedures to is olat e the failin g FRU (do not isolate nondefective FRUs).

Verif y that al l at t ac h ed d evices ar e sup p orted by the W orkP ad 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 dis connec t all of the following devic es:

a. Non-IBM devices b. Devices at t ac h ed t o th e cradle c. External devices d. Battery pack e. DRAM f. PC Cards g. Compact Flash Cards

4. Turn on th e W ork P ad z50.

5. Determ in e if the probl em h as ch anged.

6. If the problem does not reoccur, reconnect the
