Does my Inspiron 9400 Laptop have build in microphones?

There are two possible causes for this issue:
1) Your dell 9400 charger is malfunction
2) Your laptop dc power jack is loose or dead

Possible troubleshooting step:
1) Borrow a compatible dell charger to plug in your laptop, if it works without any issue, it means your dell inspiron 9400 adapter need to be replaced.

2) If the compatible dell 9400 charger won't work normally, the problem may lie in your dc power jack.

Hope this will help.

Hello.

The most common reasons are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

You can buy one on e-bay. It is around US$ 10-17.

Greetings of the day ..

Try another headphones if possible..you have already checked the speaker so half of thework you hve already done .. try to get a diffrent headphones from friends if they work .. then its your headphone gone bad & you would need to replace it.

If you still get this issue .. please write to me .. we will work together on this issue..

Take care.

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.

make sure there is no CD/DVD left in the drive bay when you boot your laptop. Remove usb flash drives also.

Regards!

On the underneath side of the notebook there should be two screws that are usually labeled with a picture of a drum. Remove tham and the drive should slide out. Remove the drive from the tray you slid out and reverse procedure to re-install.

There is NO built in microphone with this laptop. You will need to purchase an external microphone and plug it into the mic in socket.
