In this case Dell will repair the computer if it is still under warranty.ħ.If you do hear the audio during the test but not when you boot back into Windows, that almost always means the hardware is okay but there is a problem with the audio driver or with Windows.Ĩ. If you don't hear the music during the test it definitely means there is a hardware failure somewhere in the system. The tests will play some audio and ask you whether you heard it.Ħ. Alternate between using headphones and listening to speakers in case only one signal path is working. (At this point - after you have opened Dell Diagnostic custom - if you can't find the option to select the audio tests that is a symptom of a failed audio chip.)ĥ. In that case run it from the Drivers and Utilities (Resource) CD if you have one.Ĥ.
If you have ever reformatted your entire hard drive then Dell Diagnostics will no longer be there as an option.
Dell Diagnostics should open after the PSA tests, or you should see an option to open it. Dell Diagnostics plays an instrumental piece of music complete with drums, so if you only hear some tones then you have only run the PSA.ģ. During the PSA you will hear some tones through the system speaker but this does not adequately test the audio hardware. The computer will run its pre-boot assessment tests (PSA) before Dell Diagnostics starts. Restart the computer and tap the f12 key as soon as it starts to boot up. The tests are independent of Windows and drivers, meaning it doesn't matter if those are working correctly or not. These interactive audio tests are designed to narrow down the problem to either the software or hardware. If so, then try running the audio tests in Dell Diagnostics. Have you tried listening through headphones or external speakers, not just the laptop's speakers?Īfter you installed Vista, did you next install Dell Notebook System Software and restart, then the Intel chipset driver and restart, before installing the IDT driver? Did the audio work fine, thern suddenly stop working. It's hard to figure out the chronology of this.
