Q: OK. While using my Sister's Fujitsu's Laptop computer,I decided to plug in my headphones to the front headphone jack.And,that's when her wireless Microsoft mouse stopped working. You can still use the built in scroll pad,but not the wireless mouse. Any ideas on why it's doing this? And,how to fix it? Using Vista,BTW. Thanks!!! It is a USB wireless mouse.
A: This is actually quite a conundrum. There is no physical connection between the audio ports and the USB ports, aside from the fact that they are attached to the same laptop. On some newer desktops, the ports are now "smart" enough to detect when things are plugged into them, passing that information to the OS and the audio software. I am assuming that you are using a USB wireless mouse. Now, it is possible that incorrectly installed audio drivers could be sending the wrong information when something is plugged into that digital ready headphone jack. If you are using a bluetooth wireless mouse, it is also possible that the bluetooth receiver is turned off when something is plugged into that digital ready audio jack. As a diagnostician, I would boot to an Operating system outside of Vista first.. say a Live CD of linux Mint or Kubuntu (actually BartPE would be my first choice, but I don't think you would have easy access to that)... I would make sure that the audio devices are picked up properly, make sure the wireless mouse works normally first, then see if the condition repeats... all of this to determine if the problem is hardware based, or software based. If the problem persists outside of vista, then it is most likely a hardware issue or design flaw. If the problem does NOT persist, then the problem is within Vista. From there, it would be a matter of the results. Problem within vista? Make sure all drivers are up to date, and all settings are correct. Reinstall Vista and drivers. Problem without vista? Try a cabled USB mouse, or bring it in to a repair shop.
