VAIO Hardware Diagnostics Ver.3.3.0

The VAIO Hardware Diagnostics is a utility program that helps you to determine if your VAIO's problem is related to your hardware or not. 

Computer problems can be caused by a number of factors including the hardware itself. Software installed on your VAIO or its settings could be the cause as well.
As the first step towards solving your computer's problem, let's see if your hardware has any problems by using this software.

These tests only check certain features.Even when no errors are reported, this test will not provide 100% guarantee that the tested device is working without any problems.

The fact that the diagnostics tool finds errors does not endorse you to a repair without some proper troubleshooting being done. Troubleshooting still might be required prior to a repair.

------------------------------------

Step 1 Let's try the "Full Test"
Please use this utility in Administrator mode.

Click the [Run Test] button to start the "Full Test".
The tests start automatically. A progress bar is displayed  to show the progress of the test. The test time depends on the capacity of your hard disk. Be aware that it potentially can take several hours. Once the diagnostic test completed, the test result will be displayed. Two different messages can be displayed depending on the result.
----------------------------------------
[No hardware errors detected]
----------------------------------------
If this message is displayed, your computer's hardware is working correctly.

-----------------------
[Errors detected]
-----------------------
If this message is displayed, some or all of the tested hardware is not working properly.

If the hardware listed as defective was added after the purchase of your VAIO, please remove it and perform this test again.

If the error message persists, please call Technical Response Center for further assistance. 

Click the [Close] button to close the diagnostic window.

Click the [History] tab to display a list of the fifteen most recent logs. Older logs will be overwritten as new ones are created. The most recent test log will be displayed at the top.These logs are used for solving your problem.Please have the last log printed out or take a note of it before you call Technical Response Center.

Step 2 Let's run tests on individual hardware components.
Click the [Individual Test] tab, and select the test from the drop-down list that is related to your problem. The operations of each test are the same as the ones of the "Full Test".

Some tests need additional devices such as a mouse or a CD or DVD-ROM. Please read the instructions carefully before starting the test. When ready, click the [Run Test] button to start the test.

Step 3 No hardware problem detected...
If no hardware problems were detected by using the VAIO Hardware Diagnostic Tool, the problem may be related to your software or the environment of your computer.
