new dv6000t high pitched noises

My new 6433cl from costco is making an almost constant yet faint whine/beeping noise, almost like a high speed morse code. I hear it extremely well when I put my ear above the keyboard, more to the right side. I can hear it when watching tv and it's irritating to say the least. I have it laying side by side with my sister's dv5000t and mine is by far the louder one even when they are just sitting on the desktop. Does anyone know what this noise is?

I checked my bios too and I have firmware f.27...I hear this isn't a solid firmware version? I just got this laptop a couple hours ago, so would rolling back to an older version be a good idea?

And if possible can someone provide me with a link to a guide on how I would go about to do so?

 

get it fixed thats not normal

 

You can search the forums for endless discussions on the high pitched noise on HP Pavilions. One work-around is here: http://forum.notebookreview.com/showpost.php?p=1580895&postcount=80

However - any solution to the problem just keeps the processor from idle, makes it hotter, so the fan is on more often. So it's either the noise or the fan and neither is a good option. The problem is poor engineering/design with the Intel chips. If you do ever get the noise to stop - you'll notice that the thing is so hot it's uncomfortable. Get an HP with the AMD processor if the noise annoys you too much, or just get rid of it and buy another brand - you'll spend way too much time exchanging laptops anyway.

 

Yeah i just spent the past half hour browsing through the 6000t owners thread and tried RMClock and the USB trick. Funny thing is my USB root hubs were already unchecked but the noise was still there. I'll play around with RMClock more but I haven't noticed much of a difference.

Scratch that. RMClock did the trick. I can deal with a fan, not a whining.

New and last question...what's a safe temperature for the core 2 duo to constantly run at? I see 75* as a redline point from some sleuthing but I'd like to make sure. Right now, with RMClock and just browsing the internet I am at 50*C +/- 5*C.

Edit again: the noise seems to come back when I unplug the AC adapter. Argh.

 

It's a fault and manufacturer replaces these laptops, checked and they know this issue. Just replace it and forget about the problem. Best of luck!

 

as ickysmits said, this is a well documented problem that originates from the processor, whether its intel's or HP's screw-up I'm not sure but I've heard people with other brands report the whine as well.

50 C is fine for a laptop processor and the 75 C threshold sounds right.
For comparison, my room is at 68 - 70 F (20 - 21 C) and my processor is idling at 28 -34 C with the computer set to max battery and when set to max performance it idles at 34 - 40 C with occasional spikes to 44C

I'm running F16 which is heavier on the fans than F27, its a bit louder but keeps it cool. From what I've heard most people seem to prefer F16 but if your not having any issue with F27 then I think your fine.

 

thanks for the responses guys. rmclock seems to have really solved the problem but it has created a new one - it's running pretty hot....so i may give a downgrade to f16 a shot tomorrow. i have nothing to do until school goes back in session and if i brick it i can always exchange it.

i must be blind because i've been looking around HP's site but I cannot find any firmware to download...is there some sort of site that lists what each revision of the firmware changes? I'd like to know what i'm altering if i do decide to do so. thanks!

...but I didn't have any luck with it. I'd return it – I don't think the noise is acceptable and neither are the solutions. Like you said, the fan runs all the time because it's too hot. Another problem with the DV series is there aren't proper vents to allow for cooling. They run hot even without the the Rmclock program and they're uncomfortable to use....in other words, useless as a laptop.

In the case of the HP DV series, design doesn't lend itself to function.
