No sound speakers and headphone dell inspiron 9400

First, check that the audio is not muted, either via any hardware switch/button, or via software.

If not, I'd download and reinstall the sound card drivers for your notebook here:

you will need to select your model, or put in your service tag (on the bottom of your notebook) and then look for the driver under audio in the list.
from memory the first audio file should be the one you are after.
click on download, on the right hand side.

once downloaded, run and install software, then restart the computer.

Hope this info helps.

How do I get at the sound card on my inspiron 9400. The headphone jack needs to be serviced.

I would suggest taking this laptop to an authorized service center. Laptops are just tuff to get open and change hardware. Its more worth your time to have a service center change your hardware. Desktops I fix myself.

Inspiron laptop Battery won't charge

Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

Fast overheating inspiron 9400

This sounds like the system has glitched. Do a system repair with your recovery or operating system disc. This should clear the glitch, get it back up and running, and cure the overheating problem. Try this and get back to me if there are any issues.
