Hi ahmad alsalhi,

I would like to know is the noise coming from the system hardware components or from the internal speakers of the computer.

If the noise is from the system fans please perform the steps from this link:http://dell.to/L49lxh

Thanks very much Nikhil,

I think the noise is from the internal hardware component  it is like an unfined tuned radio channel

Hi Ahmad,

I would like to know from which side of the laptop you hear the noise, is it from the left, right, or the bottom of the laptop?

Please hear the sound carefully and reply. This will help us to isolate which part inside the laptop is causing the noise.

Awaiting your response.

Hi Ahmad,

As per the description the hard drive is present in the middle of the computer, I suggest you to update the firmware for the harddrive and check from this link: http://dell.to/Mbe3zg

Click the above link, enter the service tag of the computer and select the operating system from the dropdown and select the Serial ATA and download the firmware for the harddrive installed in the computer and install it. Restart the system and check.

Kindly post the results.

If the noise comes through the speakers see the Choppy/Skipping Audio FAQ.

Hi,

I updated the firmware but the voice still the same.I don't know what to do.

Thanks,

Ahmad
