Microphone and audio connectors issue
I just tried connect standard 3.5mm headphones with mic to Microphone and
audio connectors sockets of my Dell Vostro 1520 laptop and find that both Mic and audio connectors sockets are extremelly tight, so I need apply very strong effort in order fully insert jacks into sockets.. It's not normal, so am worried about laptop motherboard, I think Mic and audio connectors sockets are soldered onto motherboard, so force plugs into the socket with extra pressure can damage something. What do you think? Is it safe? Thanks. |

Each has a total of eight solder points, of which three points might be for mechanical support. http://support.dell.com/support/edoc...nCellFirst.jpg I can't find any documentation, to suggest the jacks aren't ordinary ones. Looking at a 3.5mm plug I have on hand here, it looks like there might be enough depth in those jacks, to accept it. Did you visually inspect the hole in the jack, for foreign material ? The contacts use spring force, to ensure contact, which provides some resistance on insertion. Paul |

Paul -------------- I tried connect this headsets on another notebook, and connector plug fits into the socket normally. So the issue is jack sockets. I inspected holes and seems one of them(audio) has a a little smaller gap between spring and contact. Thanks |

I inspected holes and seems one of them(audio) has a a little smaller gap between spring and contact. Thanks There are some jacks, which are dual mode, and have TOSLINK inside the same jack. If you look in the barrel of the jack, you see red light coming from a red LED, if that is the case. They look pretty ordinary to me. I wasn't able to find any documentation to explain how they're different. On a spare parts web page, they show a picture of the jack assembly. Apparently, those two audio jacks, are on their own printed circuit board. Now, to connect the audio signals, would take five wires. Yet, the white connector on the end of this assembly, has about eleven connections. So there are six connections not accounted for. Perhaps the audio chip is part of the assembly ? I'm not sure what that means. It means the module can be removed if it is damaged, but they might not be using screws and nuts to hold it in place. http://www.notebookparts.com/images/...e/RT882_fs.jpg With these pictures, it is so hard to reach any conclusion.

Paul -------- Its regular ordinary audio sockets. Seems assembling of these sockets wasn't accurate enough, and spring inside is too hard. I just will not use audio sockets as I 'm not sure i can safely force plug into sockets. |
