Section 3Dell laptops with HD audio all models since 2. In addition to the usual mechanical parts, the jack uses current impedance sensing circuitry to trigger software configuration and switching to send the audio signal to the speakers. These techniques are called the sense pin in this article. When the sense pin fails then there is usually this combination of symptoms    Speakers dont work and are not muted or deselectedHeadphone jack does workReinstalling audio driver does not helpAudio test in Dell 3. Diagnostics passes, or the speakers work in PSA testsOn models with 2 headphone jacks, one may be checked in the control panel as if in useSometimes but not always, a very gentle wiggle of a plug in the jack will get it to resume normal functioning, at least temporarily. That combination of symptoms means that the sense pin is not working for some reason. Failure of the sense pin results in the computer behaving like there is always a plug in the jack. The software switch that should route audio to the speakers does not get triggered. There are 3 ways to confirm that you have a failed sense pin 1. Check for the combination of symptoms that I listed. If you have all of them then it is pretty certain you have the failed sense pin. Note that when you run the audio tests in Dell Diagnostics you should hear audio through the speakers. That is the opposite result from what one would expect. But note that if you do not hear the audio through the speakers during the tests then there is some other hardware problem, not a failed sense pin. Replace the headphone jack. If that fixes the problem that confirms that you had a failed sense pin. Install My Hp Officejet 4500 Printer Without Cd. Restore the laptop to its original factory configuration by using Factory Image Restore on models with Vista, 7 or 8 pre installed at the factory or PC Restore on models that had XP pre installed.

Headphone jacks are not designed to be repairable so normallya jack with a failed sense pin has to be replaced. Changing the jack on most models requires replacing the motherboard, but some models have a separate jack circuit board that can be replaced with a new one. See Section l. V below for a list of models with replaceable jack boards. See Section V for some workarounds that will help on a few models. Sometimes gentle prodding or application of pressure on the jack case can restore functioning. On some models a salvaged jack can be soldered onto the motherboard depends on the design of the MB and ones ability to work on it. But if you are still under warranty then let Dell fix it or you risk voiding the warranty. How to Use Diagnostic Tests to Help Confirm a Failed Sense Pin. A. The PSA or e. PSA tests. All Dell laptops have this ROM based diagnostic tool. Use it to rule out speaker failure. Re start the computer and at the Dell logo screen tap the F1. One Time Boot menu appears if the computer boots to Windows turn the computer off and try again. At the One Time Boot menu, press the down arrow key to highlight Diagnostics, then Enter. Look for a Perform Quick Audio Check button on the bottom right side of the e. Baixar Narracao De Silvio Luiz Para Pes 2010 Pc here. PSA main menu screen. Press the button and check if you can hear the beep tones from the speakers. If you do not have the Perform Quick Audio Check button then do this. Start the PSA tests and when it performs the color test it will ask you if you see the color bars on the screen. Deliberately fail the test by answering no press the n key instead of yes. When you do that the PSA test will emit a series of beeps. Listen for the beeps. If you dont hear the beep tones that means that the speakers have become disconnected or have failed. Game Rambo For Pc. You do not have sense pin failure. If you do hear the tones that means that the speakers are working and are connected. If you also have the other symptoms listed above, you almost certainly have sense pin failure. B. Dell 3. 2 bit Diagnostics Tests. Most of the older models also had a set of interactive tests named Dell 3. Diagnostics. If you have these tests they will run after the PSA tests finish. Dell 3. 2 bit Diagnostics tests the audio chip, not just the speakers like the PSA tests do. However if you have the other symptoms listed above, your audio is working through the headphone jack and the audio chip is okay. In other words you do not need to run the Dell 3. Diagnostics, just the PSA tests to rule out speaker failure. Here are instructions for the Dell 3. Diagnostics. 1. Run the PSA tests see above. Dell 3. 2 bit Diagnostics should open after the PSA tests, or you should see an option to open it. If you have ever reformatted your entire hard drive then Dell 3. Diagnostics will no longer be there as an option. In that case run it from the Drivers and Utilities Resource CD that was shipped with older Dell laptops. Select Custom, then the audio tests. If you do not see audio tests under Custom, that is a symptom of a failed audio chip however if your audio chip has failed then you would not have any audio at all neither through the speakers or headphone jack. The tests will run. You dont need to run all of them. Just check whether or not audio comes through the speakers during the tests. The Dell 3. 2 bit Diagnostics audio tests play a complete piece of music, not just beeps and tones like the PSA tests do. If you dont hear the music that means that the speakers have become disconnected or have failed. You do not have sense pin failure. If you do hear the music that means that the speakers are working and are connected. If you also have the other symptoms listed above, you almost certainly have sense pin failure. Headphone Jack Problems on Older Models with AC9. Audiothe 2. 00. 5 Inspiron 9. Dell laptops built before thenThese old models did not have a sense pin in the jack and so do not have the failed sense pin issue, but there could be other problems with the headphone jack. There is a mechanical switch between the headphone jack and the speakers but no software, so if the audio signal gets as far as the jack but not on to the speakers it is a hardware problem either in the switch or in the wiring to the speakers. When you insert the plug into the jack the plug pushes apart the spring contacts and breaks the connection to the speakers. When you pull out the plug the contacts should spring back together. If this fails to happen due to a misaligned contact for example, you wont hear sound from the internal speakers. Sometime gently probing the jack with a q tip can restore functionality. If the speakers work when you apply pressure to the case then the problem could be a bad solder joint where the jack is attached to the motherboard instead of a bad spring contact.
