Mice and Pointing Devices

This is not a very in depth guide, but will let you know what to expect. I used some foam packing material that came with my graphics card. I'm sure any foam will do. Just cut what you need.

This first image I have already removed the housing and the foam is already there

This next image show you how to remove the wheel

next image just shows screw placement with the wheel removed

next image shows you where I put the foam material. Make sure you surround the housing completely. Make sure you use extreme caution if you remove the laser.

finally put another small piece of foam over the circuit board, make sure you do not cover the led lights or you won't get any light indication when charging the mouse, turning it on and when the battery is low.

these are the steps I took to muffle out the noise enough to where I couldn't here it. If you screw up your mouse I'm not responsible for replacing it sorry.

I'm returning mine as defective due to the buttons not clicking properly. A single click on mine registers as a double click, it won't click and drag. Crappy battery life and now to see this issue which you've had to disassemble to fix!

Logitech used to be such a good company, I was so loyal but my frustrations with this one product -- which I had to select to take advantage of the unifying receiver -- is just the worst.

Every mouse in my house is a logitech one and none of those have given me problems. 

If they send me a refurbished one in exchange for this defective one, I'm going to keep sending it back.

Thanks very much to Cursnik for posting the instructions for fixing this.  My sanity has been saved!

Already sent 1 of these back for this and battry issue.

This second one, is even worse for noise, I'm now getting a massive electrical "click" on each movement of the mouse wheel.

As well as the squeeking and hissing, wheazing noises on every movement, this is not an isolated issue, I wish Logitech would reply to comments about this issue.

While I admire your inginuity at atempting a fix by voiding the warranty, and possibly creating a heat issue, that could cause a short or even a fire, I couldn't justift throwing £70 away doing the same.

Does anyone have an update on this? I found this thread while searching Google for my problem.

But I just now had a really weird experience.

I didn't notice my Performance MX making the screeching/whining/hissing/squealing noise during movement until yesterday. But I also had a weird problem come up that the mouse's battery indicator blinked red, and then shut off.

The mouse came back on and worked fine—but with the noise.

While I was reading this thread, the mouse blinked red again and came back on again. (Battery was fully charged.) When it returned, the noise was gone.

I have no idea what happened, but I thought this strange experience could help find a solution.

I have had the hissing problem appear after a few months use.  It has gone away at least once and returned without relation to charging or anything, so I'm not sure that is a factor.  I am considering trying the foam solution, it's starting to bug me quite a bit.

Did the foam solution today and it helps with the noise, although I didn't succeed at making it inaudible entirely.  Guess it needs more foam that I could cram in there, or better.  But bearable now.
