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 Utility before you run PC-Doctor. On the BIOS 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.
