Batch Mode Testing

PC-Diag PC Diagnostics Software examines  the computer in  test groups. Test groups include Motherboard, Memory, Video, Fixed Disk, CD, Floppy Disk, Video, Serial, Parallel, USB, Year 2000, Mouse, Joystick, and Keyboard.

You may run a group or individually selected tests in a group, then run single or multiple passes for either an amount of time per test, amount of time for the group, or number of passes for each test. Test time can be up to 100 hours (four days plus four hours).

You may also select Batch Mode testing and save the test parameters in a batch mode file.  Batch mode testing is also called "burn-in" testing because it runs continuously for a long time and heats up the circuitry. Batch mode tests can simulate a month of normal operation in just a few hours of intensive exercising.

When creating a batch mode file, you can select any test in any group,  then select which devices are to be tested (e.g., which hard drives if you have multiple drives),  you may then select the amount of time or passes for the tests, elect to exit the program and return to the operating system when testing is done (so as to run other functions in AUTOEXEC.BAT, for example), and elect the destination of the test log (full log or just summary, to go to printer or file). You may even elect to put the Snapshot Configuration report in the beginning of the log and customize a header and footer for the report.

An important feature for systems builders who burn-in many systems at once is the dynamic test result display. The software can be set to halt on a failure or run continuously. If a failure does not lock up the system, then the monitor, if attached, will display a large, red FAIL message, and the floppy drive LED will flash rapidly. This will alert a technician across the room that a failure has occurred.

Batch Mode testing is a very powerful way to burn-in test a system after repair or before shipping a new system to a customer, for it provokes any imminent "infant mortality" failures while in the shop, rather than in the customer's home or office, and it thereby reduces warranty costs for both the customer and PC technician or builder.

Full Logging of Configuration and Test Results - PC Diag provides thorough log features to record your test results and configuration information. View results of batch test on your screen, print out your results, or save your results to a USB Flash Drive. Elect to log only the testing summary showing number of passes and number of failures for each test, or each iteration of each test in a batch mode burn-in test sequence, plus the summary. Because you can log configuration information, you have a handy record to use to verify the customer's system if it is returned for service.
