Re: Hi I'm also experiencing a cpu whine problem on my T430s....

2013-03-20, 7:30 AM

I've sent my computer to Lenovo service (via Teleplan) twice now, and both times they've rejected my claim.  I even submitted a complaint and they rejected that as well since they don't believe my claim that Lenovo found this problem before with the T410 and T510 computers. (http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T510-i5-540M-terrible-whine-noise/m-p/717175/)

 

If a Lenovo employee here on the forums can help with this, I would greatly appreciate it.  This is getting a little ridiculous.

I'm still around and I'm monitoring this thread for any updates.

 

For the most part, I've given up on hoping for Lenovo to fix this issue in existing laptops or even to address it in upcoming models. An issue with the power management on their motherboards has been causing this noise for over half a decade now, and Lenovo is either not interested in doing testing for this sort of thing or not willing to pay for better components to prevent it. Most people probably don't even notice this issue because the common problem with the fan cycling on and off every two minutes is much more annoying.

 

It's not a matter of a few defective computers--it's an engineering problem that affects most if not all of them. I imagine Lenovo spends more money on "repairs" (motherboard replacements that don't fix the issue) than they would on actually addressing the problem in future laptops, but it looks like they're more interested in perceived cuts to cost than in performing that analysis.

 

I'm learning not to get frustrated while using the computer in a quiet environment, but it's still really annoying. I unfortunately don't have the time to fight this fight. What would it take? You could probably spend a year and not even receive a quiet laptop yourself, much less a fix to the problem for others.

 

I really like most aspects of ThinkPads--and I often recommend them--but I always mention this issue. It makes me pretty pessimistic about things to come.

Hi guys - bumping this for you to say that this issue is prevalent on my new Thinkpad T440p as well.

I'll have to try removing the battery to see if that changes anything.

CPU whine and thoughts on new models

Then it looks like there's at least one element of the ThinkPad tradition that Lenovo didn't get rid of with these new models. Why did it have to be this "feature"? Couldn't the company have at least fixed this seriously annoying issue during their process of getting rid of every high-end and unique feature the ThinkPad used to have?

 

In a year and a half, I've gone from recommending ThinkPads to everyone who asks (and many who didn't ask) to thinking that just about any other laptop manufacturers must create a better machine. Lenovo's gotten rid of the features that made the ThinkPad great without fixing any of its problems (with the exception of finally including some decent displays). It's really unfortunate what's happened to the company's products since they dropped their commitment to quality and started chasing after the low price / high volume combination. I really hope another company steps in and revives the legacy of their older machines.

I agree. No idea how this issue can be overlooked. Especially when purchasing brand new top of the line equipment, this has proved to be a box of worms. And mine is more of a "CPU scream" than whine, unfortunately.

How hard do you tend to push the machines? Maybe the components need a stronger burn-in?

Just a totally random thought.

Re: CPU whine and thoughts on new models

I want to bump this thread because my T420s experiences the same issue. I just had the motherboard replaced, and the coil whine occurred with the old and the new motherboard. As mentioned, it's definitely most noticeable when running on battery power.

 

Would be good to get a resolution, and I'd like to know the link between this and the other hardware problems with the T420s (e.g. noisy fans, dodgy motherboards). It's my gut feeling that there is some sort of inherent power/voltage issue. The only thing I can really compare it to, was working on old PII & PIII desktops that started failing intermittently because of age and dust. However my T420s is nowhere near as old or dusty...

T400 with this issue also. It's not as lound as some have described but siting in a quiet room I can faintly hear it. Its very evident when you place your ear near the fan location.

 

 Has anyone found any solutions to this?

Fortunately for the T400, the CPU core voltages are unlocked. Back on my T400, CPU whine would go away when I applied undervolting.
