Appendix B.

Problem solving

Computer

problems

can

be

caused

by

hardware,

software,

or

user

error.

You

might

be

able

to

use

the

information

in

this

section

to solve

problems

yourself,

or

gather

helpful

to

a service

technician.

You

might

also

need

to

refer

to

your

computer,

operating-system,

or

sound-adapter

documentation.

You

can

also

use

the

problem-solving

diagnostic program

for

DOS

on the

IBM Option Diskette

. For

more

information

on

the

diagnostic

program,

see

“Diagnostics” on

page

Troubleshooting

Your computer or CD-RW drive does not operate correctly or the busy indicator light does not come on.

Take the following actions:

1. Check that the CD is loaded with the label side up.

2.

Check

that

all

devices

are

properly

connected

to

the

and

the

electrical

outlet.

3.

Turn

off

the

computer,

unplug

the

cables

from

the

electrical

outlets

for

your

computer and

all

attached

devices,

and

remove

the

computer

cover.

4.

Check

that

all

power

and

IDE

cables

are

securely

attached.

Disconnect

the

IDE

cable

and

check

for

bent

or

misaligned

pins.

If

you

do

not

find

any

problems,

reconnect

the

interface

cable.

Replace

the

computer

cover,

and

reattach

by

pressing

the

Eject/Load

If

the

light

does

not

come

turn

off

the

computer

and

try

using

another

4-pin

dc

power

cable.

5.

Check

that

the

color-coded

edge

on

the

IDE

cable

aligns

with

pin

1

on

the

IDE

port

and

is

closest

to

the

power

cable

on

the

CD-RW

drive.

See

“Step 3.

Selecting

an

IDE

port”

on

page

6.

Check

that

the

IDE

is

connected

to

the

proper

IDE

port

connection.

See

on

the

system

board,

remove

the
