This is what I sent to HP:
Please provide the exact problem description. | A low intensity buzzing noise coming from the under-center of the computer keyboard. Sounds like the harddrive (please do make no mistake: i know the difference from HD spinning normal operating noise - this is different)and the buzzing noise seems to come and go. The problem has already surfed on the net (for example one thread see http://forums.cnet.com/5208-7587_102-0.html
forumID=69#threadID=238102#messageID=2428779#2428779)so I am not the
only one, experiencing this problem. I tried to change the Notebook
Settings Power Managment (as been suggested by others thinking of the
buzzing coming from the battery) but the buzzing seems related to the HD spinning or as others suggested maybe the Intel Core 2 chip? The problem does not seem software related or display. It is not the fan noise, please.In general, I am a very easy with noise (I live in NYC) - but the buzzing becomes unbearable after 1 + of use in a quite environment - so for a $1,300 brand new computer is not acceptable. Otherwise, I really love the computer, and the HP online ordering + shipping has been a great experience. Please help, I hope that it can be stopped or must return computer. BTW, I could not get through the Tech help on the phone or online chat - I tried several times.

Has anything changed since the unit functioned properly (installation
of SW, settings, cabling, etc.). | The unit never functioned properly.
The buzzing noise was audible from the first time I turn on the computer
out-of-the-box on March 13th. Nothing was added.


Anyone knows anything specific about this? Thank you. Massimo.

Hey guys, if you had looked around the Apple MacBook and MacBook Pro complaint sites, you would have noticed a great number of complaints about the same thing (and a lot of other MacBook / Pro complaints too). This FLAW is all thanks to the flaky Intel Core 2 Duo chip and it is well known on the Apple side.

The Apple MacBook and MacBook Pro (both VERY buggy notebooks that Apple DOESN'T make (Apple has NEVER made their own notebooks) uses the exact same Core 2 Duo series, although a higher clock rate, and probably the same Intel Mother Board as HP, Dell and likely many others. In fact the Apple MacBook and MacBook Pro's are probably made at the same factory by the same contractor in Commie China.

By the way, don't believe all the BS from the Apple Droids about how reliable Apple MacBook and MacBook Pro's are, your HP, Dell, Toshiba and Sony's are far less buggy. You want to know how buggy Apple portables are, just visit appledefects.com and macfixit.com a couple times a week.

I have a HP DV6540 and a G4 PowerBook, I'll take the HP over the Apple any day now.

I do have a question - has anyone noticed that the battery in the DV6000 series seems to drain a little too fast after charging, with the HP turned off for a few days? Like losing 5% a day discharge?

i got a dv6130us and it makes that noise, i dont know whats up with it, neather does hp or circuit city where i bought it. every one i picked up and tryed switching out made that noise. for something thats 1200 you should not have to deal with this... i think a class action sute needs to be filed. but tell that happens i need a fing laptop to use for audio produstion so off it goes to HP agean... please tell me of anything you find.

hey BALESTREm, would u kindly tell me wht is a step to disable intel CPU C4. also is there a any disadvantage after disabling that function.. thanx plz reply soon

hey thanx balestrem. CPU C4 disabaling works eliminating noise. i really appriciate it. i was curious to know if u have came up with solution to constantly running fan? thanx my configue is intel core duo 2 1.60 GHz, 2 Gb ram, vista home premium. thanx again.

This should work for all Pavillion 6000 series. Again make sure that you have the most recent BIOS (F.16). you can check it by restarting Windows keeping the F10 key pressed. Check the version and update by downloading

Follow the steps in my previous posting.

I have AMD 2G. 4G and it has same problem CPU NOISE AND AC NOISE -- HP LAPTOP Dv7-1132 also has noise problem from cpu , I sent it back to HP after 2 months OF trials with hp customer service online and phone calls support. but I am very sad they did not fix the problem , I got my laptop returned back with same problem , they even did not explain what they did -- no feed back from CS to show what they did ? I dont think they did any change in the laptop..

Thank you so much for your help. I've followed the link, and downloaded and installed F16 version. But, when I tested out I still have the F13 version. Do you have any idea about why I can't update my BIOS?
Thanks!!!!!!!!!!

I'd check out the thread on NBR that covers this exact issue:

http://forum.notebookreview.com/showthread.php?t=85477

there's a ton of discussion and solution suggestions there

After almost going out of my mind working with HP they gave me a upgraded brand new computer. Guess what....it had the same noise. I must have spent 8-10 hours with these people

Anyway. there is a work around. The problem is that this model has a fan that makes this noise and you have to set the bios so that it will not enable the fan at a certain setting.

My I had an HP dv6xxx with an Intel Core Solo CPU from bestbuy(cant remember exactly) and it made the electric buzz sound that is caused by the cpu because when under load the cpu doesnt do it, only when under no or light cpu load and the noise is louder when on battery power. HP claimed a bios update would fix it but it did not. I eneded up getting a different HP laptop DV6000 with an Intel Core 2 Duo T7200 and it does the same thing, HP claims again a bios update will fix it but I havnt tried yet and am going to try what was posted on here. It is NOT the fan doing it on either PC.

As far as Macs, I have no clue but do know windows is a bloated operating system that hog resources seriously and they get worse with each new release. Vista sucks, it hogs resources like no other and speed boost is nothing more than a marketing gimmick! It usually doesnt improve system performance to a noticable level, this comes from various computer realted mags and my own tests on a vista machine. I have 2 upgrade sent to me because of the two pc's for Vista Hime Premium and after trying it out on a pc (not mine) and reading about it, I decided to stay with XP Media Center until Vista is improved more. Vista mike look cool, but performance is more important to me if you have to sacrifice too much. I have 2GB ram in my laptop but still dont want Vista, becuase it would be like having only 1GB in XP if I upgraded.
