Checkout guide Checkout guide 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: http://www.lenovo.com/support Creating the PC-Doctor diagnostics diskette To create the PC-Doctor disk from the Rescue and Recovery workspace , do as follows: 1. Enter the Rescue and Recovery workspace by pressing the Lenovo Care button during POST. 2. When the Rescue and Recovery workspace finishes loading, click Diagnostic Diskette. 3. 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 diagnostics. 24 MT 0689, 0768, and 0769

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:
