Possible. But sometimes it seems louder when, for example, the hard drive
isnt being accessed.

Hi!

> Thanks for the information William. You may be right.

I might need more information. How loud is this noise?

I've never heard one that was so loud it could be heard over any
program material outside of my experience with a Compaq LTE 5000. On
that machine, it was just possible to make out the soft but repetitive
sound of something happening periodically during quiet passages in
music.

> Is the DC-DC converter replacable? Might it be going out?

Sometimes it is a separate board. It's unlikely that it is going out,
but it probably is being loaded differently by the demands of a
different OS. Even very well designed switchmode power supplies (which
is basically what the DC-DC converter is) aren't absolutely quiet, nor
do they have 100% quiet output.

Circuit traces, grounds, coils and other parts may act as unwitting
antennas to radiate this noise. Or something in the audio circuit may
be insufficiently filtered or acting as an unintentional antenna/
receiver.

(This is why the majority of stereo receivers and decent quality audio
equipment use big old heavy transformers...they're not as efficient
and have to be pretty heavy to stand the load, but nothing beats one
for *quiet* output.)

this is a common problem with the vostros 1500. if you use google to
search for "vostros 1500 noise" you will see lots of hits including a
youtube video that demonstrates the condition. there is also a thread
on the dell community forum about this problem that was addressed by
dell replacing the effected system motherboards. given the age of the
machine i suspect you are no longer under warranty and so they may not
be so cooperative in helping to solve the problem, but it is certainly
worth calling dell about it. good luck.

I had that with a Dell 1420 machine. For other reasons, I replaced
the headphone set with a USB set, and was delighted to find the
internal noises had disappeared. You can also find mini usb to
headphone adapters, which will allow you to use your old headset. I
have seen these adapters for $5-10, and sometimes a cheap as 3 for
$10.

I saw those a couple of days ago on a website. I have a pair of USB 5.1
headphones. But I prefer to use my sony fontopias. So I may look into the
mini usb adapter.


Thanks,
Greg
