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. 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. 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.

Each diskette is erased and formatted with the PC-Doctor for DOS boot image. 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 Checkout guide To run the test, do as follows: 1.
