Question about Dell Inspiron 700M Notebook
My Dell 700m screen got hit by friend's kid yesterday, and after that there is no sound come out from the computer. If I closed the screen down half way, then the sound is coming out. How can I fix this problem? Thanks.
Ok, the real solution to this problem is that the wires for the speakers run through the right side hinge, when the screen opens and closes many times (twisting and untwisting the wires) the wires break.....solution is to disassemble the screen shroud and hinge, and run new more flexible wires through the hinges. clearances are tight and the painted panels on the 700m scratch easily, but it can be done. If you have the speakers replaced the same brittle wires will be put in and they will inevitably break after a year or so anyway.....good luck

The first thing you needed to tell us is if the speakers are located in the screen or the body of your laptop.
You don't give specific enough behavior on the system accident. Did the kid slug the screen with his fist, or did someone bounce a baseball of a vase off it... Did he slap it closed.... Was the screen or the case the point of impact?
Test your audio hardware with a music CD, and headphones. IF it works then you've eliminated some possibl shorts. If you get uninteruptible sound in a head-set, then it's likely the connection to the speakers that's shorting.
Likley as not, it is one of 2 things. Since you get any sound at all suggests that there is either a transient short to the pouwer supply or a transient short from the audio port to the speaker.
Transient, as it was described to me, is simply a short which causes the componant to sometimes work, or to sometimes NOT work. I am as serious as a heart attack when I tell you my buddy has a woman's virator in his tool box, so he can prove if a part had a transient sort by introducing a safe, high density "micro" shake to the part. That causes the componant to exhibit in a rhythmic but sporadic failure. Then you start looking for the two places that might be at. The 2 major places are always your supply, and between whatever directly provides output to the module in question.
As long as you DON''T puncture the screen, and you DO stick to places where there could be shorted wires, you should be okay.
This is what I would do.
1) I'd put a CD into the computer, then I'd check my audio software to make sure it was playing.
2)Whether or not I got sound I would try to reproduce the fault.
IF the fault occurs in headphones then the short is between your CD drive and whichever parts or wires cconvey the current INTO the board or into the port
If the fault only occurs in the speakers go to step 3
3) Turn the vibrator on and place the business against the case part of the laptop screen. If the fault is in the speakers then it is probably the connection to the speaker.
. If the short is in there, you'll have to take the screen apart and carefully look for a short circuit there. A transient short is most likely caused by a sharp blow, and in places where you have wiring soldered to a denser frame work, or lighter gauged wire, the heavier of te two is "thrown" harder and will separate from the solder joint.
If the fault isn't there put the vibrator the the keyboard casing and see if it happens there.
If it happens there, you have to check the physical ports involved (in the audio modual) in question, from port to speaker, from CD player to port or sound card.
