The whining.....please.....make it stop.....!!!!

I've had my M1330 for almost a year and a half now. Since the moment I received it until now, I have suffered from the CPU whine. I have tried everything : I update the BIOS, and have tried RMClock (has a tendency to cause my system to freeze). Does anyone else out there have any other alternatives.

I'm gonna assume that the reason I can hear the whine is because I have sensitive hearing. I've asked many people (when I sit next to them with laptop in hand) if they hear a whistling/whining type of sound, and they all said no.

 

its a natural sound coming from the cpu when it is in a low voltage state, have you tried disabling the lowest state of voltage in rmclock?

if that doesnt fix it, then im afraid nothing will, if its excessive, however, you could give dell a call...

 

I've tried disabling the C state (don't remember which one exactly). But it did work for a time, but then my computer would freeze on me at random times

 

Agreed with Koer..if this is really excessive, and a bother for you (it would certainly be for me)...use your warranty and have Dell fix it!

Hmm, how should I put this........






.......my warranty died on me 4 months ago.


I dont think exchanging it would solve the problem. I've tried that before with Dell, and I'd get the same whining sound from each and every replacement.

 

Oh noze That's too bad.....There has to be some resolve for this! Do not give up!

I'm not giving up. To give up is to have wasted so much money on this laptop.

One thing I noticed though: The whining will occur immediately after I type in my password upon startup of my laptop. All other startup processes prior to startup, I don't hear the whine.

 

Did you try the USB Root Hub trick?

 

What trick is that? Could you explain it to me?

 

Of course. The trick is to disable a power-saving feature of your computer's internal USB, so that your processor never enters the C4 state that causes the whine.

It's pretty easy:

- Open Device Manager (you can access it through the System control panel, on the Hardware tab).
- Expand "Universal Serial Bus controllers".
- You should have several "USB Root Hub" listed. Do the following for each one on the list, going from top to bottom:

• Double-click it, click the "Power Management" tab.
• Uncheck "Allow the computer to turn off this device to save power".
• Click OK.

- Once you've updated settings for all the USB Root Hubs, you're done. I am not sure if restarting is required for the changes to take effect, but restarting won't hurt.

Note: the whine noise is caused by your processor going into a lower power C4 state. The only way to make the whine noise stop is to make sure that your processor doesn't go into C4 state. There are several ways of achieving this (the USB Root Hub trick is one of them), but as a result your computer will run a little hotter.

 

All of those USB hubs were already unchecked without my input.

 

Really? That's uncommon. Try checking the checkbox, clicking OK, then unchecking the checkbox and clicking OK again.

Are you sure that the noise you're hearing is the CPU whine? If it is the CPU whine, the noise should stop when your computer is under load. If it doesn't stop, then it's something else.

 

The noise does stop when under load.

Edit - I tried to click in the check box to check them, but when I restarted my computer, they were already unchecked.

 

Then your only remaining option is RMClock, I'm afraid. Make sure you have the latest version and only change the setting related to your issue (C4 power state).

 

I've already tried that, and it causes my computer to freeze.

 

Then you're out of luck?

If I'm not mistaken, disabling a power state is persistent (not across reboots, but you don't need to leave RMClock running), so after the change has been made, you can simply close RMClock.
