Lenovo 8098 manual Diagnostics using PC-Doctor for DOS

Chapter 5. Diagnostics using PC-Doctor for DOS

Diagnostics are provided by the PC-Doctor program for DOS. These include a full range of diagnostic utilities to determine the operating condition of the computer’s hardware components.

You can the run diagnostics from the Rescue and Recovery™ workspace or you can create a bootable diagnostic diskette from the Rescue and Recovery workspace. Alternatively, you can download either a diskette image or a startable CD-ROM image (.iso file) from the Customer Support Web site and run diagnostics using them.

The latest version of the diagnostics program is available from http://www.lenovo.com/think/support on the World Wide Web. Type your machine type into the Use Quick path field and click Go to find the downloadable files that are specific to the computer. See “Diagnostics program download” on page 50.

Diagnostic error messages appear when a test program finds a problem with a hardware option. For the test programs to properly determine if a test Passed, Failed or Aborted, the test programs check the error-return code at test completion. See “Diagnostic error codes” on page 61.

If an installed device is not recognized by the diagnostics program, that device might be defective.
