High Pitched Noise from new Pavilions

do you have the noise problem now ? do you disable C3 ?

 

Well, if it's so loud people are returning computers for it then there must be some MAJOR issue. Mine does not make any sounds other than the fan turning on and off and to me that's normal with any computer. Has anybody heard an XBOX 360?

Anyway, my machine has the F1.6 bios installed and there is no high pitched noise that I can tell.

 

i did not disable the c3. i haven';t noticed the same high pitched whine that i had before. i will post back if the whine comes back.

 

Did you try to disable C4 in your BIOS? That worked for me, and I didn't have to install RMclock, nor is the CPU at 100%

Ps. To make RMClock start on login, just put a shortcut to it in your "Startup" folder in the start menu.

 

Another Vista thing I found is to right click on any file you want to run and select "Run As Administrator". This seems to make things go more smoothly.

 

I have the high pitch sound as well. The c4 and USB power setting seems to diminish the "eeeeee" but it is still there. I wonder, are any of the Intel PRO wireless users getting this noise? I am using the Broadcom wireless device.

From reading these posts its obvious that the hight pitched sound that we are all experiencing is common amongst the intel 2 duo chip notebooks.

I read that Hp is going to use the new INTEL SANTA ROSA CHIP as of may 9th, 2007. Does anyone know if they have attempted to resolve the high pitched noise withe the new processor?

 

I think we will just have to wait and find out, hopefully they will fix it with the new CPUs!!

 

Santa Rosa is not a chip, but a chipset. However, it's hard to say exactly which chip it's coming from, so Santa Rosa might fix it.

 

So you think if the new Centrino Pro machines are quiet, they (HP) will replace our buzzin Pavilions by warranty? For free?

 

They might replace it if you make enough noise about it, but I wouldn't expect some sort of official program. Every computer will have some noises with it.

 

I've been talking to HP support today, and they told me they expect some new software from Intel soon. As they say, it should fix the buzz issue. We'll see..

 

really, that's some good news!

 

Hey guys,

Like most of you, I have the exact same problem with the sound. Anyways, I was wondering if any of you have noticed that opening iTunes and playing something (even if your sound is on mute) automatically takes away the whine. Maybe it has something to do with iTunes being such a memory hog?

 

Yeah, I noticed that itunes runs the cpu pretty hot a lot of the time. So since it's not in low-power state, it doesn't have the whine.

 

HI!
I has the same problem.
I bought my hp pavilion dv 6119ea with my F.05 bios. Then i updated (i don't know why) to newer f.15 then i has same problem with my fan. It always works and dont stops ever. ( doesn't mater if it was vista or xp) fan problem doesn't changed. Then i asked hp support they sended to me (they sayed newest bios f.16) i flashed bios again. No change same thing.
I sended notebook to hp back (it taked 10 days) they sended to me back with bios f.20. I dont know where they got it. but now fan is stable and laptop is wery wery quied. I still woring about my cpu it pretty hot it runs around 50degrees then funs start run intensively. Now i installed vista and seems to be OK. No buzzing noise (C4 disabled) no fan noise. But i think it is hot that because before with f.05 bios notebook runs around 40 degrees.
I think i leave this now like this it is stable now and no noise.
Before Hp updated my bios to f.20 i tried Rmclock and other all kind of settings- NO HELP!
I have Core Duo T2050, 1GB ram, Geeforce Go 7400 (256mb), 120Gb HDD.

I hope my inforamtion help somebody.

Sorry aboud my bad english.

 

Hi all,
Just got through reading this thread and I have a dv6000t like some of you. I upgraded by BIOS to 16 but I'm not computer savvy enough to disable the CP4 thing. I did press F10 and it brought me to the BIOS page but it said something along the lines of non execute so when I pressed enter it exited the page. Help?

 

this high pitch noise only happens when i use my battery but when i dotn it dosent happen.
ps the high pitch noise only comes on when im doing nothing on the computer

 

The little mosquito inside is really bugging me and I'm used to them. I have to watch tv or listen to a radio next to the computer to cover up the noise.

 

I dont know if this helps. I just purchased a V3000z and the noise was there. I just upgraded to the latest bios F23 or something, and the sound is gone. I dont know why, but I also feel the laptop a little bit cooler.

 

I have a dv9000t and I only have the noise when my wireless MS intellimouse is plugged in through the USB. Has anyone found a solution to this?

 

I have the same problem.
The high pitched (eeeeiiiiii) appears almost every time especially when I used laptop without AC adapter. It disappear when I press the up, down button to scroll a website. Sometimes, it disapear or smaller when I change the frequency of CPU ( I used Notebook Hardware Control program). And this sound is very loud when I download or upload with high speed (>300KB -->11MB/s).
I tried many ways to eliminate this sound but unsuccessful. I'm tired with this sound. I also asked HP and they only said that upgrade my flash BIOS to 1.6 and if this sound still exists bring my laptop to HP service.
Is there any solution for this situation?
I hate HP. I don't know why in some laptop review site, they said that my laptop which is in HP dv6000t series is the silent laptop. It's a lie, a defraudation. I was fool to believe that and decided choose mine.

 

what have you tried? i had the same issue with a different notebook, and using rmclock solved the issue. people have listed a few fixes here in this thread. the problem is with the cpu, not hp. it is found on many different models of notebooks, though not all notebooks exhibit this problem.

 

Don't know how it happened but mine is dead silent in all aspects. It can happen. Any CTO units out there have the whine?

 

Hey everybody when I first got my dv9000t I had no problems with the high pitched noice, but after coming back from repair (all they did was install new bios and drivers, windows) I have the annoying high pitched noice. I did notice that they updated my bios to F.17 so maybe that is the problem. I want to go back to F16 and hope that the problem wil dissapear. anyone else using F.17?

 

This is all HP says about the problem.

As in my signature, my unit does not whine or run the fan abnormally. I am really happy with it.
So reading about the disabling of the CPU C4 I got curious and looked into my BIOS to see the setting. It's enabled.
I have to believe it's a hardware problem they will not admit to. Perhaps I could compare my hardware list to one that whines we can figure it out for future owners and they can return them before it's too late.
Just tell me how to capture it and I'll post it.

 

If this is such a big problem with a lot of people i don't see why HP won't do anything other than what sbeen said. I am sure it's a common problem that needs to be fix by HP and needs to stand up to it and admit it is a big problem with most users..

 

I picked up my DV6305US (DV6000Z series) from Office Depot on Sunday. When I first got it, I thought you guys were nuts. The only buzzing I heard was from the slowly spinning 5400RPM hard drive- which is only noticable when you put you ear right up to the bottom of the notebook.

Then today (about 4 days after I bought it), I started the laptop. I have been playing HL2 last night just to see what the integrated 6150 go graphics could spit out (I'm fairly impressed), so I had the power features set to Always On so the turion x2 wouldn't underclock while Steam unencrypted its' files. I went to bed after a while of gaming and woke up and took it into bed (on battery power, still on Always On). After a few seconds, I really noticed a buzzing noise. I thought it was the hard drive, because it seemed whenever I did something that would normally cause the hard drive to seek, it would stop for a second. It really sounded like an amplified hard drive motor as it's spinning. And it also sounded like the noise was coming from around where the hard drive is.

It started getting really annoying, so I stopped back here to try some of the remedies I remember seeing. Disabling power features on USB didn't work. It was then when I remembered it's on battery power and not set to Maximum Battery, so I switched over to Maximum Battery- and wow, the buzzing stopped. Maximum Battery, btw, undervolts and underclocks the processor to save battery, which is likely causing a change in power to other components as the power hungry processor suddenly requires less power to operate.

HP really needs to fix this. It's extremely annoying, especially to a silent pc nut like me.

Here are some tests:

Battery Power; Max Battery: No buzz.
Battery Power; Always On: Buzz.
AC Power; Max Battery: No buzz.
AC Power; Always On: Buzz (but quieter).

Being on AC Power seems to have an effect on the buzz, but underclocking/volting has more of an effect, reducing it to pretty much nothing.

The buzz, oddly enough, seems to be coming from the hard drive area. Could it be that the drive is not getting enough power and is causing this noise? This would be the most ideal fix, swapping hard drives until we find a model that isn't so picky.

 

i wonder if the new dvx5xxt series have this noise issue still or did they fix it with the new models?

 

I hate HP very much. I already use RMclock but the high pitch noise still exist especially when I use battery with max performance profile. And with RMclock, in battery profile, I just feel quite when I set 8.0x 1.250V for P-state transition(PST) and 0 - 12.5% for throttling (ODCM) . But this profile make my computer very slow , evidence for this is that when I playback a video , this will be slow and paused. I'm afraid that this is not good for my laptop. Can anyone give some comment or help to me?

 

I disabled C4 and the noise disappeared, but so did my battery life! According to RMclock, I had a battery life of 1hr and 45min (T7200). After disabling C4, battery life dropped to 1hr and 4 min. I re-enabled C4 and the battery life is still 1hr and 4min!?! I don't think I should have to buy an extended battery to get more than 1 hr battery life.

 

I have a dv6000t and like many other dvXXXX owners I was greeted with a high-pitched noise when I started using my brand new Vista laptop. The HP update your BIOS and turn off CPU C4 function barely reduced the noise. Instead, I installed XP and got rid of the noise. I then found out through the help of a CNET thread ( http://forums.cnet.com/5208-12546_102-0.html?forumID=133&threadID=243153&messageID=2470945) that the noise is not related to Vista/C4/USB but to the Intel SATA AHCI controller. During the install, I had to disable SATA native support. XP installed with the Intel SATA controller vs the SATA AHCI controller. After installing, I did some research on how to re-enable SATA native support in the BIOS and came across the CNET thread. One of the posts led me to a link that showed how to re-install the SATA AHCI controller in XP using WinRAR and MagicISO to extract the files because the HP SoftPaq was requiring a floppy which I did not have. As soon as I installed the AHCI controller and enabled SATA native support in the BIOS the NOISE was back. (Went from quiet to squeal with AC Power, C4 Enabled, all devices plugged when AHCI was installed) It really got loud when I upgraded the Ricoh controller driver which I think is tied to the SATA controller. The SATA AHCI controller gives some performance boost using command queueing but nothing worth the peace of not having to listen to that annoying sound. Can anyone relate? All the other devices are working in XP. I did not bother installing the driver for HP QuickLaunch/QuickPlay because I did not want that feature. After running the Driver Scan at driveragent.com, the only out of date driver is the Ricoh controller, not a big deal, and my Photosmart 7850 driver. I may try Vista in a year. Hopefully by then HP will either recall my laptop or come out with a driver fix for this SATA controller. Until then, my ears are thanking me.

Intel's chipset utility shows the following:
Detected Chipset:
Mobile Intel(R) 945PM Express Chipset
Chipset Components
Memory Controller:
82945PM
I/O Controller:
Intel(R) 82801GBM I/O controller hub (ICH7M)

This was after removing AHCI controller. Before this the I/O controller showed as: 82801 GBM Sata AHCI Controller/82801 G Ultra ATA Storage Controller.

I just got my new dv6500t and I can hear the high pitched sound.

 

too bad !!!

 

coz its Core2 Duo. Gotta see if this issue is resolved in future Quad Core laptops.

 

Mine is silent. Nothing disabled, SATA is as purchased, no tweaks or hacks. Performance wise she screams. The whine to me is still a mystery.

 

When I'm on AC with Max-Battery, it does sound like the buzz happens at around the same time as the hard drive is accessing. So it could very well be SATA related. Good post cookts. I'll look into this a bit more.

 

My suspicion is that any buzzing noise could be coming from different places in the system, which is why people here are pointing to different sounds and symptoms. IMO, if the sounds goes away by using RMclock, then it's probably the chipset/throttling issue. Otherwise, it could still be something else, like the drive, etc...

 

ok, i'm about to purchase HP Pavilion dv6358E. have some questions. which series of Pavilions this laptop is? and how can i check if it's affected with high pitch buzzing noise issue or not? cause these are things that'll make my decision. thanks. it's equipped with amd dual core processor - does this still mean sound could persist?

 

Very anoing sound! My head is going to explode...

 

How about the warranty? Does HP takes back the computer?

And is there any sure sollutions?

 

And something else! Is our laptops brokendown? Or it is ok with the sound?

 

http://forum.notebookreview.com/showthread.php?t=126149

I'm trying to confirm this, but if my suspicion is correct, whatever is causing this noise problem may also be causing distortion in image quality on external monitors (connected to either an HP docking station, or to the Pavilions VGA out).

The noise I might be able to live with. But when something causes video quality issues, it becomes major.

 

Has anyone shipped HP their notebook for repairs and actually had this problem fixed? HP wants me to ship my laptop in for repairs, but I'm worried it will leave me without a laptop for a few weeks and then when it comes back it will be the same way.

 

From HP support (nice quick reply btw)

Of course the static theory and bios theory were both wrong, but I guess they had to have me try some stuff before they would initiate a service return. They say turnaround is about a week. Anyone else experience HP repairs recently? Can I expect to be without a laptop for 2 months?

 

Is the new dv9500t /w santa rosa platform affected by the high pitch noise?
9500t owners please let us know your feedback.

>Frustated also with high pitch noise!!!!! Finally fixed it by selling it to my family relative >>>means no more headaches...replaced it with Sony VGN-FZ190 models,wow a difference night and day....lightweight and very quiet....just my 0.2 cents.

 

Ok, I just sent in my system. But I didn't just have a resonance noise, I also had VGA out degradation during the resonance.

1-2 days to ship there. 5 days to fix. 1-2 days to ship back. Let's see if it's fixed (I highly doubt it).

 

the static theory is not so wrong, when its on AC and the batery is full is when i get the loudest sound. and when I move my finger around the mouse pad thingy it feels like the static when you do the same with a tv screen after just been turned off. anyway I did the procedure of pressing power for 60 secs, and the noise has been reduced like 90% even with c4 function enabled. I think it could be totaly fixed with some cross wire inside that releases the static.
