High Pitched Noise from new Pavilions

[Calvin]

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/g...reg_R1002_USEN

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.

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/g...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.

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.
