Hi all!

I just purchased a new HP computer with dedicated graphics and it's very fast.

But ONE thing I noticed when I first plugged it in, was that it was making a high pitched yet quiet tone. I did a bit of SEARCHING on Google and FOUND out that some power supplies do this when something has gone wrong and now I'm getting a little paranoid from it.

However I also read that some power supplies do this even when nothing is wrong.

Today when I went out I put the computer on Sleep. When I came BACK, it was making the same noise. But there's a little light on the front of the computer that flashes during Standby/Sleep (as a feature) and the tone or pitch CHANGES as the light flashes on or off. If I turn the computer on, the noise seems to go away or is not noticable.

Should I use the warranty? Or am I worrying too much for something normal?

Thanks,

~DairymanDepends how high pitched it is?...

many small fans make that noise, even big case fans do.Warranty...that's what it's there for.Ya, return it.  It shouldnt be making those soundslike i said some pc's just make that noise.... even mine does, and i know its the fans,,...
