M1330 High Pitched Whine

Can someone please direct me to any thread that has a for sure answer on this.

I've updated my bios, video, intel chipset drivers. The noise doesn't seem to occur while I'm constantly using the touch pad (scrolling)

My dad can't hear it but I definitely do, my sisters do, and it's just plain awful. I really love this computer but the noise is unbearable when it's on any flat/hard surface. It's fine on the couch or on my lap. It's like tables/desks/etc amplify the noise and I just can't take it anymore.

I can delete the thread after I find a solution. I know there's others but it seems like each one is a little different, and since the bios update didn't do anything I was hoping someone knows of a solution to my exact case?

I'm calling Dell later, but I really want 'sending it back' to be a last resort.

 

does it change with brightness? Mine kind of had the same thing and I realized that it went away with brightness all the way up. That made me realize that it's probably the LED backlight voltage regulators and now that I at least know what it is it doesn't bother me anymore. The sound did seem to change while touching the trackpad.

 

Bumping this because I'm having the same problem.

At least for me, it's not solved by adjusting the panel brightness. It does seem to change with what's being rendered on the screen, though.

 

The processor whine is the intel processor entering different levels of sleep states.

If changing brightness affects it then it is the inverter for the monitor.

They are separate issues, but nothing is wrong. Its just something that needs to be dealt with.

 

The only sure solution, so far, is to have the mobo replaced with the A04 one...

 

Oh, say it ain't so. Would a BIOS "downgrade" also help matters? I don't wanna go through the hassle of notebook ping-pong.

Is there any power management setting(s) that I'm overlooking that might help? I'm not much liking this.

 

I have the same whine with my 1330, but it doesnt bother me too much.
I used to have this whining with my Latitude D620, and I solved that completely by entering theBIOs and changing the USB setting to 'high-speed'. This was disabled by default since it consumes more battery power.
Dont ask me why and how this stopped the whining. I simplay have no idea. But it worked, completely. When I turn off the high-speed setting again, the hining starts, so I know thats definately whats solved it.

However, in the M1330, I cant find any similar option in the BIOs......I hink we are just stuck with it unfortunately.

 

My A04 whines, the only solution is RMClock.

 

WTF
you want to delete the read after you find the solution.

aren't you aware that people may BENEFIT from the solution?

I won't assume that you're a selfish ****. IF you are then you don't deserve anybody to help you, and you shouldn't ask. So, why would you want to delete the thread?

If you do find the solution you Should post it.

 

Whoa there. You're right, but... damn.

Oh hell no. I'm just really anal about sound, I guess, but I'm not sure I'm willing to stick with this obnoxious whining EMI-like sound.

There's got to be some sort of way to shut that up.

 

I solved mine using RM Clock and it's a very very simple solution. I have an Inspiron 1720 and it works like a charm. Just see the screenshots and follow it exactly.

However, I do not guarantee if it works on your notebook.

If you see your laptop exhibiting strange behaviour or freezes after this is being applied, reboot to save mode or do not allow RMClock on startup.

You'll need to access 2 options on RM Clock, Chipset and Processor.



Instructions: Make sure you look at the ones marked in red, to be exactly the same as stated in the screenshots. The orange highlight (apply at startup) is your choice, if you see any errors and problems, do not apply at startup and reset to default settings. Perhaps one of the most important step is to choose chipset type as "Mobile" instead of "Desktop". I did a research and most of the time a laptop crashes because the Mobile option is not selected.

Once again, I am not responsible for any loss or damage done on the notebook. I;m just trying to help because it worked for me and my whining situation without any problem or freezes on my Inspiron 1720. I have read around and it seems like the solution works for other models as well.

 

Thanks for posting that. It does seem to help with the majority of this nasty whining sound.

Oddly enough, I can still very faintly hear it from time to time; not sure if there's something that can be done about it, or if I'm just being too picky.

 

I can't hear anything on my 1720 at all even in my Dark Room where I develop my photos or in my home. Since it works without problems, you might want to apply at start up so that it works all the time.

Hey er... if it works, gimme a rep point. Your wish.

 

I think it might've just been environmental noise; I can't hear anything right now, and all I've got on in the room is a TV that makes no noticeable noise like some of them do.

So yeah, definitely +repped. Have you noticed a significant impact on battery life while using this?

 

Hmm... I'm always on Plug... So, no not really, I don't think it really affects battery life drastically. But that will depend on the type of battery you are using. Mine's a 9 Cell battery, so typically about 3 hours, on full load, 2.13 hours + like that...

Thanks for the point... I'm glad the solution helped.

 

Fine, ignore my post then

You could also undervolt your CPU to get more battery life using RMClock.

 

Hah, sorry about that

 

Before trying RMClock, I spoke with a rep who suggested that I do a system exchange. Are some notebooks capable of using C4 sleep without that high-pitched whining sound, or should I not even bother with a replacement?

 

If you stick your ear close enough to the notebook, you will definately hear some sort of whine specially at startup.

Get it exchanged if you have the time to go through the hassles.

 

The 2 A04's I've heard and my refurbed A01 mobo have all had identical CPU whine and it was always solved be disabling popup in RMClock.

 

Meh. So after doing this for a week or so, the RM Clock suggestion seems to cover the whining issue, but at the expense of something like 20-30 minutes off my 6-cell battery.

Even worse: after several hours of uptime, it seems I'm prone to hard freezes. It's happened a few times thus far.

Please tell me I have a third choice besides "deal with obnoxious whine" (which I will not do) or "deal with periodic hard freezes" (also not willing to do this).

 

I had 3 m1330's all with varying revisions of motherboard and bios. All of them whined- it's an inherant fault of the chipset design.

Rmclock does not completely stop the noise either... in every case I could still hear the noise (albeit very quiet).

Having to run software that detrimentally effects your battery life is not a solution. Keep sending them back until you get a good one / decide to get a refund.

 

Yeah, I can still faintly hear the noise, too. If you kept returning your laptops, did you eventually get one that, despite the same features, didn't whine? What'd you do?

 

I'm sorry the solution didn't work out for you. Well I guess this fix proves it's for the 1720 owners only.

For my machine, RMclock manages to stop the whining completely, didn't hear any noise even at 3am at night when everyone's asleep and my watch is making a loud ticking noise instead.

My machine didn't crash at all despite the fact I rendered over 100s of 3d max files, played countless games, CPU intensive work, and the same activity goes on for 4 long months and also more than several 10 - 15 hours of use a day. It had once didn't shut down for a week and it turned out alright.

I still have 4 hours battery life despite the fact the tweak is running and does not detrimentally effect battery is, and seems, the solution for me.

Anyway for your case, I tried, and it failed. So good luck if you can find a new solution or a new replacement.

 

I had stopped using RMClock with my 1330 as I was able to get used to the whine, but recently it's got *alot* worse, to the point that it bothers me even when there is other noise in the room (tv sound etc).. It keeps oscillating and is really grating.

Problem with RMClock (I just disable popup and popdown) is that it turns the laptop into a furnice.. Both sides of the palm rest are roasting and the trackpad is really hot as well.. It's making me sweat just using it now..

I do have a cooler which helps but as noted the battery life is killed...

Just wish there was a better way of solving this.. Like others have said, changing h/w is not guaranteed to change anything..
