Re: New W510 - High Pitched Whine/Sqeal Using Battery

Hm, that's exactly what I have there, too.

Re: New W510 - High Pitched Whine/Sqeal Using Battery

Update after a long time:

 

Over at http://www.thinkpad-forum.de/thinkpad-hardware/w-serie/86013-fiep-fiep-w510-problem-hochfrequent-und-spa%C3%9Fbremsend/ we seem to be getting a bit closer to the source of the high pitch:

 

1. There are two separate high pitches: One which apparently results from the C4 CPU state and is rather stable and one which occurs only in battery mode and can be suspended by audio playback (no matter whether the speakers are muted or not) – the one we're talking about.

 

2. We removed the keyboard to locate the whine's origin. There's one coming from the DIMM area – the C4 whine – and one coming from the left bottom – where the harddrive is located. However, a user at thinkpad-forum.de stated that he also noticed the pitch with the hdd removed and it might rather come from the bluetooth device (which I cannot confirm)…

My W510 also have high pitched whine/squeal, regardless of running on adapter or battery.
I have disabled CPU power management from the BIOS and it eliminates the sound, but I can't forever have CPU power management disabled as I will bring it out and use it at other place, which hurts battery life.

 

Model No: 4876-A11

 

My W510 has been serviced by Lenovo once, which is about 1 month ago, have motherboard, speakers and keyboard replaced. Then now, high pitched whine/squeal and overheating issue arise.

Great News! I have just received back my W510 yesterday and the buzzing sound was fixed by replacing the Processor.

Sorry for the rather late reply. But is it really *the* buzzing sound which was fixed? (Meaning that there're actually two of them.)

 

Also, is there any part ID which you could post? Maybe I can get my retailer to get this exact CPU for me… :)

 

[EDIT]:

I've just noticed your previous post:

…which means that we're not talking about the same high pitch…

I am not sure, I just know that they replace my processor and the buzzing sound was near fully disappear. Currently, when my W510 is on battery, the buzzing sound is not noticeable unless your ear is very near to the Intel Core i7 CPU. (Left-rear) Which is fully-acceptable.

 

Since the processor is replaced by Lenovo Engineer, you will be able to check the part ID from the website. As they did not note the part no. of the part being replaced.

 

My W510 is using Intel Core i7 720QM.

 

Best Regards

Peter

Is the consensus that the whine is definitely the CPU as it relates to the way it powers up/down & that although it's a chip design replacing the processor in some scenarios somehow fixes the problem?  I'd rather go down the replace the laptop/CPU road vs screwing around w/ power settings.  Disabling the power features in the BIOS didn't even help.  It seems like everyone's situation is just a tad different even though, in general, we all share the same parts.

And I have a Core i5 560M which may behave differently than the quad core CPU.  No everybody mentions which CPU they have.

w510 & Squeal

2010-11-22, 15:27 PM

I have read a few posts about the CPU whining noise & especially when it's running on battery power.  I was wondering if anyone knew if this was more noticeable on the dual or quad core CPU?  I have the Core i5 560M & it's pretty noticeable even when plugged in.  I am hoping a CPU replacement will help but it sounds like this is the design of the chip, motherboard, etc. that is responsible so swapping out the CPU is just a slim possibility for fixing the noise.

Since using the latest power manager, I never notice any squeeling noises, ever. Battery, 90w or 135w power... Are you absolutely sure you're system has all the up to date drivers?

I have Power Manager 3.30 which I believe is the latest. My laptop is also all up-to-date w/ all the Windows Update components. Are you saying that you did have the squeal *before* updating to the Power Manager v3.30? The only solutions I have read about were to either a.) Turn off the CPU & PCI Bus power features in the BIOS, b.) Disable "Deep Sleep" in the Lenovo Power Manager settings. PeterWTG's squeal went away w/ a CPU replacement which, although great news, surprises me since this seems to be a hardware issue/design. Any info you have is great! I want to keep my w510 so badly but I feel like a bat when I hear this high-pitched squeal.
