High Pitched Noise from new Pavilions

Oh my god is this gonna affect my DV6000Z??? Now i'm scared.

 

I just got the dv6000t Intel Core 2 Duo and had the same annoying noise. Luckily, HP has a fix on their website. If you have a newer BIOS, then just follow the steps for the BIOS SETUP, it worked for me! http://h10025.www1.hp.com/ewfrf/wc/...5412&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN

 

new firmware F25, again much less noice
http://h10025.www1.hp.com/ewfrf/wc/...&cc=us&dlc=en&product=3369389&os=2093&lang=en

 

Is it a significant noise reduction over the F16 BIOS? Also, can you notice any battery life differences?

 

I updated, lets hope for less whine.

 

sometimes its completly quiet, and sometimes it whines. but c4 is enabled. so its good. have not tryed yet disableing couse it starts heating more and so the fans becomes louder.

 

Guys!! I did not read through this thread but i found it on google. Go into your BIOS and DISABLE C4 CPU or whatever iteration of that as it is called in your bios settings and restart your PC. No more high pitched noise. Dv9339us here... noise went away after doing that. Apparently you lose about 10% batterly life, so just enable it when you're on the road and deal with it. this is my first HP coming from DELL and let me tell you, so far this pc trumps any experience I have had with a dell laptop. Those things are complete cr@p.

 

That might work for Intel based Pavilions, but disabling power management on AMD based Pavilions has an opposite effect, and in my experience, contributes to VGA out interference.

 

Hi, it’s Anna from HP Total Care,

I’m sorry some of you have had trouble with that high pitched noise coming from your notebooks. Go to http://h10025.www1.hp.com/ewfrf/wc/...5412&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN to find out more information about what can be done. Note: this is ONLY applies to notebooks with Intel processors.

This BIOS may have an impact on your battery life, so below are some ways to conserve power.

Some features that can eat up battery life are the glass transparency and Aero displays. You can deselect them through the following process:

Right click on a blank area of desktop.
Select Personalize from the context menu.
Click Window Color and Appearance Option. Here, you can check or uncheck if you want to Enable Transparency or not. You can also disable the whole aero glass theme from here. Just click the link at the bottom that says “Open classic appearance properties for more color options.”
Select a non-Aero theme and click OK.

Here’s tip number 2:

Click on the start/pearl icon and type in the word “performance.”
Choose Performance information and tools.
Click on Adjust visual affects.
A box will likely pop up to get your permission to continue. Click Continue.
Choose the option that says Adjust for best performance.

Here’s tip number 3, which will stop HP Total Care Advisor from launching whenever the PC is booted up:
Click the “wrench" icon in the upper right corner of the HP Total Care Advisor display—that will get you to the Preferences page.
Under General Settings, click the checkbox to uncheck the Launch HP Total Care Advisor automatically on start-up—that will deselect that option.
Click OK, then you’re done.


I hope this is helpful.

Anna

 

We have recognized previously that disabling the c4 function does reduce the high pitched noise. However for many of us, it does not reduce it enough and is still very annoying. Some people have stated that they have sent in their notebook for repairs regarding this problem. Could you give us any information on what the problem was diagnosed as and what steps were taken to fix it? Thank you for your help, it's nice to see someone from HP taking notice of a very widespread problem and addressing its customers directly.

 

so does HP just plan to let the AMD people live with the whine?? They have somewhat of a fix for Intel buyers, but what about AMD?

 

Do we still not know if this is a problem with the Intel chips or with the laptop manufacturer? I dont want to disable my cpu's ability to go into a lower power state. Why has no one answered why reducing a cpu's power state would cause a high pitched sound?

 

People have replied. "we found out that it is apparently caused by power supply capacitors in the notebook that resonate under certain power configurations and thus, producing an audible buzz." I've seen a more technical explaination somewhere.. I don't want to waste the time searching for it.

My undergrad college gives its students Dell D6xxx's. They also had the same high pitched sound. The model I had would be two years old now... it didn't even have a dual processor in it but still had the same sound. I used RMClock back then...

 

I have had my laptop for about 3 weeks and it makes the horrible high pitched noise noise when on battery power. It seems to be ok when on external power.

The worst thing is when I take it to the library at Uni and all I can hear and some other people is this annoying whine. I can't use it on battery and what I needed the laptop for.

I have recently upgraded to F25 bios and that was a waste of time. On battery it is still there with and without C4 on. And I don't think HP should be calling a fix of turning off a feature that is needed for a mobile lapto that dominates battery life.

To me it does sound like the whine of a capacitor, because I had the same thing on a DSL router that made the same noise and that was due to a capacitor.

I am going to call HP and get them to either fix it or give me my money back? I don't know if I can get my money back because I bought it in an electronics store ( Dick Smith Electronics in New Zealand), they are an HP reseller I think.

Cheers

Send it BACK! The more that call and raise cane and get a RMA, the better odds they will fix it in future models. You shouldn't have to pay 1k for something that needs repair. Call and give em heck!

 

Also with the new bios, disabling the media control button beeps doesn't work anymore. with F16 bios I could change the button beeb to disable and they wouldn't beep any more, now with F25 they still beep disabled or enabled.

What also worrys me is that HP is trying to fix an obvious hardware problem with software. Software doesnt make a high pitched noise, hardware does. So even if they do manage to fix it, it will be whilst compromising performance or like so far battery life, and that still doesnt even fix it.

 

Ditch it ASAP!

 

Thanks, mal5z. Your solution worked for my HP dv9000.

 

Hi, yeah I just bought it 15 days ago today. But I'm not sure if I should take it back to the shop or ring HP on Monday and ask them for a refund?

The guy who sold it to me was a good guy and I'd feel bad if he had to get the sharp end of the stick...

 

You need to re-think who is getting the sharp end of the stick!
Mine does not whine or get hot or run the fan hard. If it did it would have been shipped back ASAP.
Now they want you folks to tweak the configuration into a less than efficient state just to cover up a mistake they made, or a hit they took from the hardware mfg. They are passing it on to the consumer and some are taking it big time.
I don't know how I got so lucky, or what the ratio is between the noisy and not, but I would have returned it so fast and without prejudice.

Good Luck

 

i bought a pavillion 9 series about three weeks ago. this rhythmic whining is very quiet, and somehow piercing. truly annoying, as i work in a very quiet place. so basically there's no solution yet? the bios updates aren't complete resolutions, and HP hasn't directly addressed the problem?
If so, then it seems i've nothing left to do but return the machine and go with another brand. can anyone recommend a comparable notebook pc? it's really too bad, i dig the aesthetics of this thing.
thanks,
cmr

 

Yep took mine back today got my NZ$2188 back. Now I don't have a computer and don't know what to get. I liked the look of the HP and its features, maybe I should wait a bit longer and get one with the 8400M? Darn HP for buggering up such a sweet laptop.

 

hm that's weird, the high pitched noise coming from my laptop is reduced drastically when my external hard drive is not plugged into the laptop. can anyone explain to me how this happens?

 

Follow these instructions... claims to cause the least amount of battery life reduction...

It is crazy that we spend so much of our time tracking down a problem that should be taken care of by the manufacturer. To share a recent story: I bought a Microsoft Wireless Laser Mouse 6000 keyboard and mouse a couple of months ago. I installed their "Intelli" software and the mouse pointer started moving erractically. I called Microsoft and they said to replace the batteries. I indicated they were brand new. I was told to still replace them. Then I asked them about their bulletin Q321122 that address' "The Microsoft mouse pointer moves erratically..". The tech told me that my definition of erractic was not the same as their definition and my issue was not software related. I hung up at that point. I followed the lengthy bulletin's directions which the tech would not assist with and the problem is resolved for now.

Is anyone of the Intel users with the high pitched noise NOT using the following Intel chipset/controllers? If so, what network controllers are installed?:

Mobile Intel(R) 945PM Express Chipset
Chipset Components
Memory Controller: 82945PM
I/O Controller: Intel(R) 82801GBM I/O controller hub (ICH7M) which was 82801 GBM Sata AHCI Controller/82801 G Ultra ATA Storage Controller when I tried to activate SATA native support but rolled it back because the noise returned.

Network Controllers: Broadcom 802.11 b/g WLAN & Intel PRO/ 1000PL

 

Do the DV6000t's with just a core duo make the same noise. Because I can get one with a T2350 which is clocked at 1.83GHz. Can someone confirm for me that the older core duos don't make this noise and that it's just the core2 duos and the Turion64's??

Cheers

 

Do the new 8400m Laptops have it? I'm about to buy a 6 series pavilion but if this is a serious problem... I odn't know...

 

I have a core duo dv9000 and it had the whine. However for some strange reason it was only really apparent when my external hd was plugged in. With the fixes in this thread though and
http://forum.tabletpcreview.com/showthread.php?t=3516
I can't hear the noise anymore.

 

Nope, Got a T2350 and I still have the bloody noise. I actually think it is worse.

Man, if I take another one back there going to start to get pissed off. Disabling C4 on this one just makes the fan run constantly and I still get the noise on battery. I don't seem to always get it when the power cord is plugged in.

If XP is installed does it stop it or do people with XP still have the problem?

 

G'day all,
So i have a Presario V3000 AMD Turion 1.6ghz, and like everyone else here im getting this constant emf noise both through the internal speakers and headphone jack. Ive tried the RMclock fix, disabling power saving on USB and almost every other fix listed including unpluging everything and its still there.
The only impact on this sound was when i changed power mode to "portable/laptop" as suggested. although it is still there if i turn my amp up alittle more then usual.

Supprisingly the only time it does disappear in windows is when I load the sound driver installer from HP not run it just run the exe and have the window minimised. This is very stange as this has the same effect in all power modes. BTW file is http://h10025.www1.hp.com/ewfrf/wc/...n&cc=us&dlc=en&product=1817059&os=228&lang=en
So i just have this in startup now and minimise and forget.

So back to the cause/point. This seams to be an issue with both the power saving scheme at a hardware level and a driver conflict.
The mentioned resonance between the caps could be true, though should/would affect all power modes and across the board and does not explain the installer ceasing this noise (for which i can not explain either although the installer puts a 40% load on CPU even when idle) The noise is alot worse when i browse in explorer to a directory localy and massive when over a LAN so this leads me back to it being EMF, although again why that driver installer fixes it im stumped.

So the only fix ive come up with is the above mentioned installer, not that its a fix more like gaffa tape, but its leads me to think this CAN be fixed with a driver, Hint..Hint..HP you twits, re hire your engineers and put them to work.

LIFT YOUR GAME HP, this is poor service at its best!

Ps. Big ups for this thread i though the noise was in my head till i read 35 pages of the same dramas.

 

So, anything new how to fix this problem?

"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..." WOO! Anything new about this?

 

Sorry to disappoint you, but HP quoted that lie months ago. If you go a few pages back on this thread you will read where a 'tech' support person said this to someone else.

I own the dv6375, T7400 (2-2Ghz processors) chip. RM clock stops the noise. I had to buy an extended battery to get over 1 hour battery life (w/WIFI).

 

Hello, I have HP Pavilion dv9346ea.
Went to the Device Manager in Windows Vista, then -> Bluetooth Radios -> HP Integrated Bluetooth module -> Unchecked the flag "Allow the computer to turn off this device to save power". The noise is gone!
I also have original (F17) version of BIOS that came with the notebook and Option C4 = Enabled.
I really hope this helps someone else!

 

What does cpu c4 do in the BIOS? I'm going to send my laptop back the second time since HP didn't do anything except reformatted the hard drive. The noise that I'm hearing from is on the left side of the touchpad. It seems to me it might be the ram area since it cannot be the hard drive...

 

I just installed Windows XP Media Center Edition with all the DV6000 drivers from HPs website and now the sound is GONE.

It must be a vista/vista driver issue. Now my laptop runs faster with no noise and I think even the battery lasts longer. I don't need C4 disabled (F16 BIOS) and I just left native SATA support on and had no issues with XP installing on a SATA drive.

I'm super stoked now. Just get rid of Vista and say goodbye to the noise!!!!

 

I recently bought a dv9207us from CompUSA and there is a very slight hissing/high pitched noise coming from around the touchpad area. The sound is prevalent when the machine is on battery. Currently its not loud. Can be heard faintly when ambient noise is minimal.

mark205gti - if the noise is due to vista then we can probably wait for an update from microsoft to solve this issue...or is this wishful thinking.

I'll try the RM Clock fix once the noise gets to an irritating level.

 

FYI: I received my dv9500t about a week ago. So far I have not noticed the buzzing as I had on a dv9000t.

 

Its not just these HP's, its most all laptops with the Intel core 2----You will get used to it as I did--turn the TV or music up a little

 

This is exactly what i did and got the same result as you, XP is so much more responsive than Vista, and the noise is gone!

 

On the new dv6500t, which I received today, there is no high pitch noise anymore, so I guess they finally fixed that problem, and in addition I can say that the "Fan" problem is fixed, now it is working only from time to time, in idal probably every 30-40 minutes.

 

i didn't start hearing my noise until about 3 weeks after i started using the thing. i thought i was in the clear as well. now it's even more annoying than my previous dv6000t that i ended up returning to Costco. not sure if it's the new BIOS version i recently updated to so i might try flashing back to the previous one.

anyway...just stay tuned. sorry for the depressing news but you want to make sure to stay on top of things in case you have to return it

 

I see, well I hope it will stay like this in a future, but who knows...

 

Hello everybody! We have exactly the same problems with HP in France:

http://forum.hardware.fr/hfr/MiniPC...ifflement-pavilion-sujet_35113_15.htm#t670050

It is a scandal! HP has to find a solution (sorry for my bad english). In french, we call this a "sifflement".

 

Its NOT just HP people

 

Thank you for someone finally pointing that out.

It's a problem with the Core 2 Duo processors and their low-power states, not HP's hardware, people.

 

Most of people who have problems have HP machines with the Core 2 Duo. For example, no problem with Toshiba with C2D.

 

dv9339us here, just installed the newest BIOS available on the site and buzzing is gone.

 

I have a dv9000z. It is a replacement laptop but it was not replaced for the noise issue. My first unit had much more serious problems but that's another story. I am very pleased to say that I do not have the noise problem or the fan problem either. I am also running Vista Ultimate so I don't think Vista has much to do with the noise problems. Maybe I'm just lucky but after the problems with the first unit, I deserve a break.

Jim

 

I've heard reports of it happening on Dells, and other brands.

HP does not have any control over an Intel defect.

 

The capacitors resonating are not Intels defects. They are the manufacturer of the motherboards, using cheap/improperly spaced parts which are designed to perform silently at only one power setting.

All electronics resonate to some degree, but none of them should resonate at the frequency that they become audible and annoying to human ears.
