Use
the
following
procedures
as
a
guide
in
identifying
and
correcting
problems
with
the
Lenovo
3000
computer.
Note:
The
diagnostic
tests
are
intended
to
test
only
Lenovo
3000
products.
The
use
of
non-Lenovo
3000
products,
prototype
cards,
or
modified
options
can
lead
to
false
indications
of
errors
and
invalid
system
responses.
1.
Identify
the
failing
symptoms
in
as
much
detail
as
possible.
2.
Verify
the
symptoms.
Try
to
re-create
the
failure
by
running
the
diagnostic
test
or
by
repeating
the
operation.
Testing
the
computer
The
Lenovo
3000
computer
has
a
test
program
called
PC-Doctor
for
DOS
(hereafter
called
PC-Doctor
.)
You
can
detect
errors
by
running
the
diagnostics
test
included
in
PC-Doctor.
This
section
is
an
overview
of
the
procedure.
For
details
that
depend
on
model-unique
functions,
refer
to
“Product
overview”
on
page
30.
For
some
possible
configurations
of
the
computer,
PC-Doctor
might
not
run
correctly.
To
avoid
this
problem,
you
need
to
initialize
the
computer
setup
by
use
of
the
BIOS
Setup
Utility
before
you
run
PC-Doctor.
On
the
BIOS
Setup
Utility
screen,
press
F9,
Enter,
F10,
and
then
Enter.
Note:
When
you
initialize
the
computer
configuration,
some
devices
are
disabled,
such
as
the
serial
port.
If
you
test
one
of
these
devices,
you
will
need
to
enable
it
by
using
Configuration
utility
for
DOS.
The
utility
is
available
on
the
following
Web
site:

workspace
,
do

Enter
the

2.

workspace
finishes

Authenticating
the
digital
signature
takes
about
15
seconds;
then
the
Lenovo
3000
computer
will
reboot
into
PC-DOS.
4.
A
batch
file
automatically
starts
up
to
prompt
you
through
the
process
of
creating
diskettes.
You
are
notified
of
how
many
diskettes
you
will
need.
a.
You
are
prompted
to
insert
each
diskette
in
sequence.
b.
Typically,
all
you
need
to
do
is
to
press
the
Enter
key
for
the
floppy
drive;
the
system
then
formats
and
creates
the
diskette.
c.
Each
diskette
is
erased
and
formatted
with
the
PC-Doctor
for
DOS
boot
image.
5.
Once
all
the
diskettes
have
been
created,
the
Lenovo
3000
computer
will
reboot.
The
user
is
asked
to
remove
all
diskettes
from
the
drive,
or
to
insert
the
first
diskette
created
if
it
is
desired
to
run
the
