At least once a day
Hello,
This is a recap of our conversation. I am sorry to say, that based on our conversation and going through your problem with your head, unfortunately there is not always a easy fix. Your problem with the now and then of getting non functioning microphone working, is a electronic problem internal, this is because there are chips inside inside and like all electron components they ware out. In your case I believe the circuit is over heating and sense you tried this on other computers, and it is doing the same thing at least once a day, and only way to get it working again tempary is to turn off or reboot system, is not because there is anything wrong with your computer. What is happening, the circuit is overheating ( the chip) and so during the few minutes that your system is rebooting, gave it just enough time to cool to function normally again for while. The solution and only solution on my research and experience is, you have to take unit in to a good electronic repair shop, and they would have to open it up, and locate that circuit ( which will be a type of output circuit) and replace it. I also warned of the cost of having a repair place do this might not justify the fact of maybe investing in another. ( have to weigh the difference) my final recommendation is that some times, if you are nice and write a professional letter to the company, and brag about how much you love there set and is not operating properly, that a lot of times they will send out a new one for free, or they will at no charge, have you send it in, and repair it at no charge. That is worth just a letter, or second choice is a phone call. Letters seem to be more effective when it comes to them coming to the table.
Conclusion: You stated you were not completely satisfied with my conclusion on the solution, I explained that some times the only solution is to have it repaired at a service repair shop, or even replaced. Not all the time we can help with customer just pushing a few buttons to solve the problem. Unfortunately your problem is a internal electronic issue. Thank You, let me know if i can help anymore, Mike
