Humming noise on HP Pavilion dv9000

I have a dv6000 and its makes a insect tlike noise. i returned it and  got another one but that one also made the same noise. so i contacted hp and they told me that the sound is coming from the USB ports, i thought wierd but here is the solution to your problem. go to computer managment (start>right click my computer> manage), click on device manager, select the universal serial bus contollers ( there should be a few roots files that open up), right click a usb root hub and select properties, click the power managment tab, and uncheck "allow the computer to turn off this device to save power". do this for every USB root hub that you have, and the problem should go away. FYI these instructions are for windows XP.

Humming fan!......hp dv9000 = poor quality control in the manufacturing process.
I opened my computer up and took a look. What did I find? Where do I start?
On the underside of the keyboard I found 2 human hairs sealed under a solid strip of clear tape. But thats not all folks! My fan was grinding. And why was it grinding you may ask? I will tell you. A white label "Not" centered on the top of the fan blades. Crooked enough to throw it out of alignment.Took the darn thing off. Problem solved!
I also found the sticky side of adhesive tape used to hold down wires with makes a great lint trap. Simple things that can truley harm your computer.

After hours of fooling the laptop, I finally figured out the cause of the humming. It was a screw inside the battery housing,closes to the fan.apparently it was to tight.once i losen or removed the humming noise went away.Hope this helps some of you.

AFTER READING THIS FORUM I CAME TO THE CONCLUSION THAT MOST OF THESE PEOPLE ARE FUCKIN RETARDS. ITS THE FAN! ITS A POWERFUL ENTERTAINMENT LAPTOP THAT GETS HOT. IT NEEDS A NOISY FAN TO COOL DOWN. BUY A SONY, PANASONIC, TOSHIBA, PACKARD BELL OR A COMPAQ WITH THIS POWER AND YOU'LL HAVE THE EXACT SAME NOISE! YOU ******* TARDS!

I got dv9000 also.. think sum thing got loose inside... make a metalic noise when i tap on the key board.. maybe sum heat shield.....

any one know how to open a dv9000??

whats wrong whit the DV'S

Its the fan!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I had a problem with a VERY loud noise coming from the fan area of my HP Pavilion dv9000 laptop after having it for over 3 years. It was really irritating me, I then looked at the web for similar problems and tried Kevjays solution (solution 13), my computer is now the quietest it has been since i first owned it. NICE ONE Kevjay :-)

Clicking sound..... metallic near front mouse pad to left side.. I tried the USB port and clicking but nothing is working.. is giving me a headache... even in mute this happens. Also for 2 days it is recovering data....any solutions

Sounds like theres something blocking the cpu fan or the fan is dieing. if you good with taking apart laptops then take it apart and change the cpu fan if not take it in to get it repair

Its not a fan, I had the same thing but its actually the processor, It takes to much juice. I upgraded to vista and the noise went away. i did find a piece of software that regulated the power to cpu and the stopped the noise as well but I cant remember what it was called.

If you get a faint clicking noise that happens even when the laptop is asleep, then its this really strange virus from the smitfraud family. Get rid of it and the clicking should stop.
As for the grinding noise, I have it too, and it always is worst after the laptop has been on about five hours, so its definitely got something to do with over-heating.

I have a buzzing sound too. It goes away when you turn the screen brightness up to full.

I had the same 'fan noise' problem and I tried all the solutions from the internet forums but none worked. After I realized that there thousands of people that had the same problem, I sent my pc back to HP and mentioned to that i will sue them using the 'lemon' law and they replaced my motherboard. It's now working perfectly and quietly.

SEND your notebook back if its under warranty. I not, buy the extended warranty and send it afterwards.

It would help to narrow down specifically where the noise is coming from. imo, there is three possible noise sources, fan, hard drive, and sound card. Is it the sound card? mute the volume, see if it stops. Is is a constant hum? the CPU fan would possibly only make a noise once the system heats up, and then not usually hum so much as it is a grinding noise. The hard drive could potentially make the humming noise, since it is easily removed from the bottom side, seems the humming would be louder on the bottom.

I am Amazed to see that i am not alone.. me too have DV9000... and i was thinking that its only with me.......well it seems like builtin problem with all of these DV9000 notebooks I think i can compromise with the sound...but if u think u can't stand it then return but leme clearly tell you... its with all of these F***ing DV9000 notebooks

I had the same problem! I solved it! Go to BIOS, find CPU4 and make it disable! It should help.
