Question about Compaq Presario 700 470024-192 Notebook
I have no sound and Mic use when connect to my PC. The headphones and Mic works perfect on my freinds PC. what can I do.
I have the same prob. no sound from on board speakers, and when the mic
or sound jack are wiggled I can SOMETIMES get sound, I believe that the
computer had external speakers attached then someone tripped on the
cord JERKING the connector all to ....well you know, how ever no one
will fess up to this.
I would like to try to replace the jacks (both are one unit, soldered to main board) however I can not find a vendor for the parts, (sound/mic jack)
I also need an illustrated parts breakdown to take the dog gone thing apart without breaking anything. any and all help appreciated.

When you insert the headphone jack into the green socket it separates a silver tab and cuts power to the speakers. These things never break. The only other options to why headphones have no single is they are either muted, or the sound is pegged down.
To check the sound levels on any computer, click or double click the speaker icon in your system tray near the digital clock display. If you don't have one, let me know. This action brings up the sound levels for all sound enabled devices on your system.
First, check that Master is not muted by a check box selected or the volume slider all the way down. Next look at the Wave slider for the same thing. If you are playing back a CD, look at the CD slider and then the volume control in your CD App for a mute box check or volume slider there pegged down. That should cover the sliders. For the mic you will notice a slider for it and that its muted by default, there's a reason but its related to feedback loops in sound, that's all.
Next, open Control Panel, click or double click on Sound and this opens several property sheets, the first one shows the built in devices for your laptop, each of the three should be filled. There at times a page for setting mic response to your voice. If you see a setup for your mic recording go ahead and run through that just to set the microphone sensitivity.
If it still does not work for you, I'm not sure what to say. I'll give it some thought so don't rate this until you hear from me again.
