cpu whime/noise probs, solved?

I used the search function, and came back with more problems. Thought everyone with the latest processors will interested in this.

Theres a high pitch/beeping/whining noise from my laptop. Its not loud, but definitely noticeable (i blame u guys for noticing it ). Its not really noticeable if its on battery saver or balanced mode, but its noticeable on performance mode. When plugged via ac, the noise usually goes away.

After searching and using google, I came across this link that explained how to use rmclock to solve this issue.

Well, it worked for me. My ultimate question is if this is an actual hardware problem with the core duo processors that can be solved via replacement or through onsite tech support, or its just the nature of the core duo processors?

Discussion and opinions, please throw em at me.

 

You can use RMClock 2.30 to disable the C4 sleep mode of your cpu. That will eliminate the cpu whine, but cost you a couple minutes of battery life.

 

I downloaded the bioshock drivers from nVidia and haven't heard it since. Been about a week I suppose.

 

Just a couple minutes...? I've heard with an ultraportable and a large battery, disabling the c4 power state can really add up.

 

Well for me, I lost about 12 minutes on my T7300.

Haven't really tested it extensively, but that's what I got the couple times I ran it after disabling the C4

 

That's funny, because I had drivers from LaptopVideo2Go and I started getting that noise, then had Windows Update update my drivers again and after windows update the noise went away.

When I did have the noise putting the power plan to 'Balanced' or 'Power Saver' made it go away.

Was only High Performance that got that sound.

 

I had it on my new R61i. My laptop would freeze up after a couple of minutes of RMClock with wireless disabled. Called tech support, they're replacing the entire system.

 

so............judging by the replys so far, im still not sure whether or not this is just how the processors are, or its an actual defect.

Any more info would be greatly appreciated.

 

This isn't a Lenovo problem, I dont think it has anything to do with vista. It has been found on macs, HPs, Dells, ect. All core 2 duo's seem to be exhibiting this problem.

I think you guys should complain to Intel about the problem since its making you turn off features of the cpu that you paid for. If I had to run something in the background all the time to keep it from "whining" at me I know I would have a few words to say to Intel.

As for me, I really haven't notice it when using my T61. But I know what you guys are talking about since I did hear a high pitch whine when I first got my desktop Core 2. Having fans turned up to high and a good set of speakers fixed that problem though

I just wanted to say again that when I changed graphics drivers the sound went away....

..odd...

I was ready to send it back too.

 

I don’t buy the argument that intel processors are at fault (something I read a lot here) and you should just live with it, install third party software, or have to mess with the system BIOS to make a laptop work like it should. That’s resigning yourself to being able to do nothing.

Quality doesn't mean that you can blame it on a vendor. Lenovo has their name on the laptop so, if they actually make everything inside the finished product or not, they are still the manufacturer and are responsible for all of the problems. They are responsible for telling the ODM what they want, approving the design, accepting the finished product, and dealing with complaints so it doesn’t happen again.

The engineers I spoke to told me that many electronics resonate and it’s a combination of all the bits and pieces that make noise (and not, for example, one Intel chip). They must test and re-test for different things because there are so many variables when they design boards. Noise is one issue, and they try to reduce or eliminate it in the design phase. All of the problems you hear about is the result of carelessness. I’m not an engineer, but it makes sense to me.

I had this noise on two laptops before and it’s painfully annoying. I was told by HP they wouldn’t be able to do anything if my problem continued. I took each one back as fast as possible. However, I understand that Lenovo will actually replace the laptop or the motherboard to make it right. If that’s true, I’d suggest anyone to keep returning it until the issue is resolved and not just accept it as normal.

 

Thank you everyone for all of ur thoughts.

I have read ur posts, ur links, searched and read through forums, and googled. I got some interesting thoughts.

When my laptop first arrived and after i set it up, there was no noise, period. Only after the thinkvantage set everything up with the security chip(after u set up windows, thinkvantage promptly askes u to set up after u log on for first time) and windows update then the noise came up. Somewhere along those lines, something happened, so some questions.

Seems like a lot were able to solve this issue with a simple driver update. Any more info on this?

Does anyone have these probs after a clean install, no thinkvantage? What versions of windows are u running? I recently handled a few vostros with xp pro and vista business, and i didnt notice any of this.

Fyi everyone, in the end im trying to avoid third party software or changes to my laptop that affect battery life and that shouldnt be necessary in the first place.

 

If you are using vista, try going into the power options and disable the Power Off Usb feature.

 

Damn it the annoying high pitch started today because I finally started working without the A/C! I can't believe this annoying problem is so widespread. Now I have to download and configure another program...

Well I didn't download the program. I just switched battery mode from high performance to balanced, and jacked up the contrast to maximum. Sound gone. I can't believe there's no manufacturer's fix!

When I go to power options, I don't see where the power off usb feature is. Could someone point me to it? Thanks.

 

wow I thought I was the only one with this problem and that my hearing was just screwed up...

I thought the sound was coming from the USB controller because it seemed to get louder if I had usb thumb drives, etc. inserted...
