High Pitched Noise from new Pavilions

scratch that, its still haunting me.

 

Is this problem still in the Santa Rosa line that just came out (dv*500t) or just the last line (dv*000t)?

 

The bios did work for me (compaq d6000t). However, the fan is pretty much ON 85% of the time which is maddening as well ! My laptop gets VERY HOT - I think if it was actually on my lap, I might get a 3rd degree burn if I was wearing shorts !

 

i noticed my dv2040tx has a high pitched noise, but only when the AC power is unplugged

 

Mine seems to do it alot now and its a on/off buzzzzz----bzzzzzzzz---bzzzzzzz driving me crazy!

But whenver I run my finger over the mouse pad to use the SCROLL function of the pad it goes AWAY till I stop scrolling? Try it

 

Mine did that as well before I switched the bios...weird, definitely weird.

 

what Bios are you running! Im runing F16

 

what about dv9500t ? has it pitching noise too ?

 

I received my dv6500t about 2 weeks ago, and it's totally silent on battery and when connected to outlet.

 

I received my dv 9500t last weekend. Yeap, it comes with pitching noise. Though I've learnt from this board and be prepared, it really cause me a headache . I've tried RMClock, USB Root Hub solutions, it helped a little. This is my first laptop, clueless about this thing. Could anyone tell me how to update Bios? Mine comes with F8. It would be my last try. If it didn't fix the noise, I have to say good bye to this laptop. Thank you guys and gals.

 

oh ! what a shame !? i wanted to buy one of this type "9500t" this week . so what's ur idea ? is it really annoying ? so should i forget this notebook ?
plz help me guys

 

Oh, yeah. It's very annoying. Even if it could be reduced by the "quick-fix" that this board mentioned, I'm still not sure if I would want to keep it. It's not right,imo, that we have to "work around" the problem to make it work.
HP should do something about it.

 

But HP won't. It's like dead/stuck pixels. The industry gets away with too much, and us consumers accept defects as the standard. Just keep sending it in for repairs, and expect nothing less from HP than a non-buzzing notebook.

 

my dv9000t CTO notebook has no high pitched sound

 

Hi all,

Just bought an HP DV6335CA (CA = Canada) with a C2D but looks same as DV6335 and man is this thing whiney! I adjusted C4 setting in bios and it's about 30% of what is was but still gives me a headache. I have 14 days to return it. Unsure what I should do.

Any takers?

Thanks,

Dave

 

You should not have to fix something you just spent your hard cash on. Give her back! This is a problem they are hoping folks will put up with.
I don't know how or why but I got lucky.

 

Thank you kindly therock.

Unsure what I should buy instead. I did a bundle of research and HP fit what I was looking for. Looking for laptop asap. Santa Rosa is supposedly a good 6 months away here in Canada.

I would consider AMD but inferior performance and terrible battery life. Any comments?

Thx

Dave

 

There really aren't that many options right now. You could try to exchange it for a different notebook (same model). Some are worse than others. My dv9500 has no buzzing at all so far, where my old dv9000 did have it.

 

Does this problem plague the dv2500t series as well?

 

I've read AMDs may not be affected. Anyone care to comment?

Thx

Dave

 

Weird sometimes mine can be very quite and I dont hear a thing all night! Other times it buzzing its self to death? Doesnt make sense to me

 

Do AMD laptop chips whine or is it only Intel?

 

AMD does it when throttled up. Intel does it when throttled down. On my AMD system, I also have D-sub/VGA-out external monitor static that happens simultaneously with the buzzing.

I'm getting a replacement... hopefully.

 

Thanks Kubul.

YOU'VE GOT TO BE KIDDING ME!!!!!!!
(Sorry about yelling but this is ridiculous!)

Dave

 

That's because when you are scrolling you are making the CPU do work, so it is not in the stepped down state anymore. When you stop scrolling to goes back down again.

 

Hi,

Does anybody know whether the new pavilions released with santa rosa cores make the buzzing noise that was a common but unwanted feature of the rest of this generation of pavilions? I'm looking at buying a HP Pavilion dv9590ea featuring the T7500 santa rosa core and wondered if it would have the same annoying buzzing that the dv9399ea I bought and returned had.

Regards,

I have 9500 with no noise at all. It's quiet as death!!!

 

My 9500 also is quiet so far. Haven't heard anything.

 

I bought a 6426us from Circuit City last Friday. It has the whine every so slightly on Battery.

I tried the USB trick no help. I tried RMClock...it worked most of the time. I updated the BIOS to F.27 and turned off the C4 function....totally silent. Even after I removed the USB step and RMClock.

I am not sure how much battery life I am loosing if any with that function off. Using Notebook Hardware Control my CPU while using still dips down to 798mhz via Intel speed step. I am rarely on battery so it probably wont matter to me.

 

Thanks for the replies,

That's interesting orev, perhaps I'll risk it and buy one. I suppose I could always return that as well if it ends up having the annoying buzzing.

Anyone else using a santa rosa core with any comments to make?

SGT Lindy, I'm glad the C4 trick worked, as it does have varying degrees of success with some users getting their notebook to be completely silent and some only slightly decreasing the buzzing noise. However, HP's current solution to the buzzing is to solve a hardware problem using software, which is never going to work efficiently. You'll probably now only get 85/90% of the battery life you got with C4 enabled.

Personally I'd rather do without the notebook running warmer and the additional fan noise that comes with that PLUS the loss of battery life so I demanded a refund on my dv9399ea until HP released something new.

Regards,
James

 

How is my notebook fan noise increasing? Or my notebook getting warmer? They way I see C4 helping me is if I am on battery and my notebook is just sitting there on....as in I am not using it.

When I am on battery I am using it or I put it to sleep with the power button, or turn it off.....in both cases there is NO fan moving and its not producing heat either. My CPU slowes down to 798mhz or whatever when I am reading something and not doing much.....and as far as I can tell the FAN in this notebook constantly runs and a very slow speed ever so quiet with or with out the C4 on. Until I stressed the CPU the other day converting a movie for over an hour I never heard the fan get louder.

 

Because it obviously uses more power when not in C4 state, therefore increasing it's temperature. For applications that don't require lots of CPU usage, the processor will be in C4 state for saving power.

Just think that if disabling C4 solves the buzzing noise for people - the means that whenever it was buzzing before it was in C4 state.

Anyway again, I'm glad that using software to solve a hardware problem works for you, and good luck with it.

James

 

On thursday, I got my 9500t and it is having the same high pitched noise, which seems to come whenever the fan kicks in... it is unlike a usual fans uffff kind of sound blowing air, it is sharp, high pitched whining noise, very distinct from other fan sounds...

Here are a few observations:
1. You can hear the noise for a while right during booting, so it is very easy to reproduce
2. You can hear the noise whenever the fan kicks in due to enhanced activity like gaming, or even a heavy web page loading...
3. In all other cases when the fan is not working the notebook is dead silent - these cases include cold air around which can keep the fan not in use for normal activity, probably this is the reason why some people are baffled as to why it keeps silent for long and then suddenly whines out of nowhere
4. The whine is low (but still annoying) when activity is low but becomes louder and louder while you play games...

Here are my specs : 2.2ghz T7500, 4 GB RAM, 17 WSXGA, 8700M GS graphics card

I am returning the notebook on monday for a replacement and I left them with a strict warning that I will have to return the new one too, this time for a refund, if the defect still remains...

 

I do not think this is the CPU Whine people are talking about. This sounds like a classic bad fan whine.

 

I won't go the service route, as this a new piece just out of box with a defect and hp will have to pay the price for not quality checking before they ship their product to an unsuspecting customer... and it is not that this is a "not so easily reproducible issue", the whine starts right at the time of booting... those guys need to be taught a lesson...

But, you mean to imply that this defect can be resolved by replacing with a proper fan?

 

I took high resolution photographs of all sides of the notebook and its parts... and told them that I did (just so that they don't repair this piece and send it back)... and of course I will verify the fedex shipping to see if the new one is coming from Shanghai or not...

 

If you return it they will almost certainly send you a new one. There's not enough time for them to try to do a repair and swap one in as "new", so don't even worry about that. When you return under the 21 day policy is treated as a regular return, not a repair.

Anyway, the whine talked about in this thread comes from when the CPU is in low power mode, which means "idle". If you hear it during high-intensity tasks, that's not the noise you're hearing.

 

RE: Visu2K7...

With HP, I would be very very careful in how you approach it. They have a published information article about the squeal that states that it is within standards...

They can simply say so sad if they want.

I know of one who has had this happen.

 

Good point, but that only applies after the first 21 days. If you're within the first 21 days after you receive it, you can return it even if you don't like the color, and they can't say anything, according to their policy.

 

But I love HP products, I own a pavillion from 2002 and a older model from 1999 both of them are working still without a single problem, display, hard drive and practically everything is very much alive, not a single thing broke... I love hp notebooks for their build and the big bang that they give to your buck, can't compare with any other brand which rip you off for the same config...

That doesn't mean I won't return a product if it has a defect.. and hp is very cordeal with my request, and they are going to send a new piece and assured me that this issue won't be there with the new one...

by the way I also bought xb3000 expansion base, I am returning that too, rejecting for now and when the new piece is up to my liking I will reorder the expansion base...

 

Not only on HP's i'm afraid.. i had the same issue on my Toshiba laptop, wich i returned...and replaced with at Packard Bell- wich of course has the same annoying CPU Whine .....kinda sucks..
Is there any solution at hand ?

Kindest regards.

 

anybody buy the dv6563cl from costco? My whining noise comes and goes when on battery... -_-;;;

 

I have it in my Core 2 Duo Dell XPS. Gets a lot louder when running on battery..

 

i get this high pitched noise as well , when the fan suddenly gets very strong, i only got this for 3 days, should i exchange this as well?
It happens after the microsoft loading screen and before the Windows sign pops up (the one before where u login to ur account) it happens for about 6 seconds

i also did a clean install, should i use the recovery disk to change it back before i return it ? ive never done this before

 

Hi, is there any of you dv2500t having this high pitch noise problem.
So far, mine is really quite, but i haven't run any heavy application for prolong period of time yet. I'm afraid this high pitch noise will start appearing once my laptop is 3 or 4 month old.:confused2:

 

This noise starts from the first moment your laptop gets to idle mode. If it's busy with processes - it's great and no noises. But when it's on idle - it starts! By the way just got my new DV9500T and no such thing happens with it.

 

Hey all,

I went back to vista because I wanted to give it another try and I got the same problem. The USB trick didn't work because it was already unchecked, but the Rmclock's HLT command did it.

While doing some research, I found that other Intel Core laptops had the same problem. I found a thread for a Dell laptop. The nice thing about it was that its bios lets you choose which sleep state to enable. He found that he only gets the problem in C3 and C4 states.

So since we can't do that with Pavilions, I tried to use Rmclock to only enable C1 and C2 states, but the problem is that C4E is enabled on a lower level. So maybe if I use this with the bios version that lets you disabled C4E, it would get rid of the noise. I'll give it a try this weekend.

 

Hi all, I actually got my way to work, I made a thread about it. Please refer to it:

Hey,

I have owned 2 of the infamous squealing dv6000t ’s. They drove me crazy . Now I am looking for a dv2500t (with the Intel Santa Rosa platform). Some have said the motherboard/chipset is the problem, other say it’s the processor. Can notebookreview.com give us an article so we do not have to read 45 pages of forums, please. Can anyone tell us if the dv2500t is a squealer or not?

And if so or if not:

1-What OS?
XP (downgrade)
Vista Home Basic
Vista Home Premium
Vista Business
Vista Ultimate

2-What processor version?
T5450 (1.66 GHz, 2MB L2 Cache, 667MHz FSB)
T7100 (1.80 GHz, 2 MB L2 Cache, 800MHz FSB)
T7300 (2.00 GHz, 4 MB L2 Cache, 800MHz FSB)

3-What graphics card?
Intel(R) Graphics Media Accelerator X3100
319MB NVIDIA GeForce 8400M GS

Maybe we can narrow down a bad combo?
Thanks,
B

 

I've tried all suggestions posted in this thread but still I have the noise *hairpull* I guess I just have to make sure I'm in a noisy room so I can't hear the darn thing!!
