High Pitched Noise from new Pavilions

Has anyone other than me contacted customer support about this??? Basically they are clueless there they told me to update my sound drivers

Of course that isnt the problem, so what exactly is the issue, i know it happens on 9000t's, 6000t's and its linked to the core 2 duo. I mean why is HP acting like they dont know whats going on here.....

 

Do you mean to say that some dv9000t have high pitch sound ? It's unbelievable!!!

There had been a similar high pitch (electronic) noise issues on dv8000t, that a friend of mine bought. We reported that to HP tech support. We at first thought it was caused by the hard disk (it seemed to come from there). What followed and how HP tech support handled further troubleshooting was "unbelievable"

At first they ignored and said it may not be so. But had to accept our contention as we showed proof. They replaced the system board and the noise was gone, but then it caused another problem. The final outcome, we ended up returning the machine...

I thought dv9000t might not have any such high pitch noise issues.

I have been planning to buy a dv9000t for some time (put off due to busy schedule). dv9000t owners would you please comment on any such noise issues ?

i have the same exact problem..........it's even louder when you unplug the ac adapter.......the high pitched noise is unbelievable annoying....

 

I also have the high pitched noise on my dv2000t.

I'm sick and tired of HP latptops. This is my THIRD dv2000t and they all have had problems. What a piece of garbage machine.

 

On your dv200t? Please let's hope they get this fixed..

 

I bet it is static electricity

 

It has to be that or one of the conductors are touching

 

If you mean coming from inside the system around the left hand side then the ZD8000's had the same problem. My current DV9000t has the same problem. If this is what youre talking about, if you listen closely to it as you boot it up it does not start happening til after windows is booting up. Also Ive noted sometimes it goes away during high graphic game play.

 

this is not a problem just with the intel based ones. my amd based 6040ca also has the same problem

 

I do not get the noise on my DV9088ea (UK version), so it does not appear to be a 'design feature'!

Well I have the DV6000z and apart from the probelm with excessive fan activity (my second fan kicks in every other minute from the very start up) I get this annoying noise too, especially when working on a battery. I sent my piece to HP service centre in Memphis and got it in 2 days back!!! (including delivery!!!!!!!!!!!!). In other words, they did not do anything with it and consider this noise as a normal state of affairs, it appears. I am going to return this computer and buy an Asus. I have honestly been extremely disgusted with HP service.

 

it also happens on my dv2000z . amd turion x2. especially when the ac is unplugged. doesn't seem like its coming from the hard drive.. but by the speaker / battery / lcd...but it gets higher noise pitch when loading something..especially when you mouse over the start menu items waiting for the menu to pop up on the right. i have 5 days b4 my hp 21 day return is over.. i like this laptop, lg screen not so bad..but that noise is annoying.. there is no point for the Mute button if noise is still coming out of this thing.

 

I have the dv6040ca (amd) and I get the same high pitched noise. It seams to come from the right hand side of the unit. If you press on the back, you can change the pitch of the sound. Perhaps it a low quality component causing the racket. Other than the noise its a great laptop.

 

Me either I don't heard any high pitches on my 6000Z model

 

i dont hear any high pitched noises on my 6000z either just the fan and thats normal.

 

I have the problem on my dv9000z too; I actually just made a new thread about it. I didn't see this thread before I posted it.

 

Hi All,
I would like to make the following summations. While this might not help with the noise atleast you will have an idea where it is coming from. First since this affects both genre of Pavillions it is highly unlikely it is the MoBo itself. The MoBo would be extensively different from the AMD to the Intel versions. It has to be a common element to both series and across multiple models. That leaves very few components. It could be the associative hardware for the screens. Every LCD has backlights, this is a very likely source for this problem. The only other component that would span both families of processors and multiple model lines is the design of the internal power supplies. While the electrical output might have different loads they would still all have 12volt + and -, 5 Volt + and -, along with the other associated power outputs for the display and MoBo. Hardrives and DVD writers are also common components across all these parameters. The final component, which is a very long shot would be the wifi board. Since Bluetooth, and the Intel verses the AMD are different it is not very likely to be the culprit. I suggest that the problem is most likely in the displays themselves, or the backlighting systems. I would suggest that you all start a thread identifying the major components of your systems to isolate the common element.
I don't have this problem on my DV5030z, but I can see where it would really be annoying if I did.
Hope this helps.

 

Another thing to mention is that if something is undervolted or over volted to some degree could cause this high pitched sound. The fact, as it is with mine, that it doesnt do it til windows is almsot completely booted up could also say something to do with the voltage as it draws more when windows is up and running that it does when its not. Either way who knows. I had my old zd8000 sent in 4 times before they replaced it with this one and it had the same issue. I decided as long as my system doesnt break I guess im not going to worry with it.

 

I dont get the noise on the computer in my sig. It is whisper quiet.

 

I got my dv6130 2 days ago and immediately noticed the whine!

Here's how to get rid of it:

1. Download RMClock from http://cpu.rightmark.org/download/rmclock_215_bin.exe

2. Fire it up, click the 'Management' link on the left, and check the box for 'Run HLT command when OS is idle'

This will cause the RMClock application to restart, and once it does, the noise is gone!!

 

In addition to what vadakr said, read this post for the less-certain but better solution and something of an explanation of the problem:

http://forum.notebookreview.com/showpost.php?p=1652387&postcount=12

 

I am a bit dubious about that being the solution due to us AMD users having this problem also. My dv9094ea have the high pitched noice when scrolling etc. I have located mine to right above the scrollplate. It sounds like a handshake from a modem.

But perhaps there are more noise problems with these notebooks.

 

A squeaking noise when scrolling or minimising a window could be the GPU. A 9800Pro in a desktop I have does that. A few years ago someone said the cause was the GPU doing blitting. Whether that is correct or not *shrug*

See, e.g.:
http://forums.macrumors.com/archive/index.php/t-127998.html

 

I tried the RMClk program and it fixed the noise. It is happening because the cpu is being undervolted to downclock it when the system isnt under a load. Althoguh my temp for the cpu core went from 28-32c idle to 36-40c idle. im guessing it wont change the temp under a load being it would have upclked then anyway. would a constant 40c be ok though with it being up clocked constantly?

 

It is not caused by the voltage, but switching between power states. If you wish to verify that yourself, force the processor to run at the maximum voltage and multiplier: the noise will not stop. However, ensuring that the CPU does not drop lower than the C1 state will stop the noise.

 

I watched what that program changed. It changed the multiplier. At idle it runs at 6x and is underclocked to 1ghz instead of staying at 2ghz. So im not sure what you are talking about power states. Either way, with it running at 40c idle is that going to hurt anything even though it runs up to 60c under a heavy load like 3d gaming

 

I don't really understand what is this high pitch noise....sounds like a dual core problem.

 

Its not a duo core problem its a moblie thing. When its downclocked at idle it makes the noise and when its runnning at full the noise isnt there. It also happens with core duo and single mobile cpus.

 

RMClock did the trick. Thanks. Any idea what this will do to battery life? Also, have we determined whether there's any variation between individual laptops? I just got an HP DV6000 and -- until RMClock -- it made the high pitched whine. Is it worth swapping it for a new one, or do they all make the same noise?

 

Based on advice from another forum (maybe somewhere in this one too), I turned off the RMClock solution and, instead, changed my USB Root Hub properties so that the computer will not turn off the USB Root Hub to save power. That fixed the noise problem and, according to RMClock, seems to keep the computer running at a lower temperature with less CPU usage than the RMClock solution. So maybe that will be better for battery life.

 

How do you change the USB Root Hub properties? Please let me know....I am dying to find a fix to this problem.

 

Yeah tell me too

 

Hopefully I can describe this right. Go to control panel. Double click on "System." Choose the "Hardware" tab. Choose "Device Manager." Scroll down to "Universal Serial Bus Controllers" and expland it. You should see a bunch of items labeled "USB Root Hub". Right-click on it and choose "properties". Go to the "Power Management" tab. Unclick the option that says "Allow the computer to turn off this device to save power." I only did it for one USB Root Hub, and it seems to have worked, but I suppose you might have to change the setting for every instance of USB Root Hub. My annoying high-pitched sound has not returned since I did it.

 

I tried it on all of them and it didn't work for me,
RMClock did the job.

 

Both RMclock and turning all the USB ports to always on worked for me. So now I no longer have to use the RMclock program. No more noise FTW.

 

Awesome, finally got rid of that noise. RMclock wasn't doing it for me, but turning on just one of the USB root hubs did it for me. Hope the noise stays away and this fix doesn't suck up too much of the battery life. Thanks for posting your solution.

 

Yah for my dv6000t shutting down the power save for the last (ie: the one closest to bottom of screen) USB root hub ended the highsly annoying noise.

 

My DV6000 with solo core was doing this too but I just did the RMClock and it fixed it!

 

MINE JUST GOT LOUDER!... why do we have to download third party applications and turn off things just for this noise to go away..? noise that should not have been here in the first place... I wonder if HP even knows about this problem.
Freakin Eh.

 

Another happy customer to add to the list. My dv6000t had this same annoying whine> I installed RMClock, set the options as per intructions found in here and the noise is gone. I only have a couple of questions/concerns:

a. There seems to be no way to uninstall this app? I checked everywhere I can think of and couldn't find it. It doesn't show on the control panel (add/remove programs)

b. I am correct in assuming that I must click on the short cut to start it each time I boot the laptop? I have the correct option checked ('Run HLT command when OS is idle') but do not have it set to start with windows. Want to keep it this way for the time being.

Thanks!

 

Hp told me to update the Bios and garanteed it would take care of the problem, they claimed it was the fan cutting on and off real fast when the cpu is at idle (thats when it does the sound on mine, only when cpu is at adle-dv6103nr and is worse on battery power). But the link they gave me to download was the same bios version as my laptop had, so it did nothing despite their claims.

 

wow! USB change worked for me. Im assuming this wont really affect battery life right?

 

If you want Rmclock to start when windows start, you need to sett it up by doing a right click on the Rmclock icon on the task bar. Doing this the it will save your settings every time turn off the computer.

 

I have BIOS F.13 which I think is the latest version. I don't feel any annoying pitch at all. Fan is rarely ticked. RMClock works great. If you want to uninstall it, make sure to delete all related register keys in table. This will save you from a correct newer version update.

 

Howdy..

just bought a dv9042ea... all is well apart from the high pitched noise u appear to be discussing... it is UNbelievable! i cant imagine it is supposed to be there for this kind of money.. and therefore mine is going straight back tomoro before it breaks my mind. eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

my question is.. will an exchange be likely to solve the problem?? i.e. is this just a design floor, or is it just bad luck..

any comments greatfully recieved thanks.

ps i know naff all about computers so please bare with my basic terminology etc etc.. i bet u guys hate that.

 

Was this the repair method for a continous whine... cause I have the AMD based dv6000 and it has an intermittant whine... when I installed the RM Clock the whine became continous however I did notice then that the whine only comes about when my CPU core clock and throttle tops out... which explains why it was only intermittant to begin with... any suggestions?

 

Does anyone heard or noticed about the cheap assemblage of the dv9000's cover (denty all over the grey skin near touchpad, speakers and so on) ? And about that many of them own a CPU WHINE? Did hp still on top of quality no matter good looking?

We have the same problem in ITALY..
Lets claim that its one of the BEST FLOP a well known BRAND had until now.

Good Luck to everybody..

About my self...the future is something coming from Levant.
I also purchased the hp DV9000T ....but got the problem i immediatly asked for the money back...the reseller was really gentle and refounded me.

Now i am going for CLEVO....i guess the best alternative for me at least.

Good luck guys and GREETINGS from Italy!

 

Here we go

 

this is my experience with a 2 day old AMD v3000 as well,

when cpu jumps to 1.61ghz noise is very noticeable, idle at .80 ghz is just barely audible.

changing power settings on usb has no effect.

when running on battery the pitch changes.



I really like the notebook, just wish i could get this processor to stfu. if indeed it is the processor.
