Microsoft Wireless Mobile Mouse 4000 Teardown

Teardown

Introduction

For this teardown you should have a small phillips screwdriver a flathead screwdriver or some other kind of prying device. A 3mm phillips screwdriver will work for all of the screws in this teardown. Note: This teardown does not include removing any components from the internal PCB.

  1. UCODBfpCNFBtaQps

    • Undo the bottom battery clip and remove any AA battery within.

    • Remove the USB receiver if stored

    • The device should look as pictured.

    • Using your prying device, pick at the corner of the lower rubber traction pad on the bottom of the device.

    • Pull this traction pad off to reveal the screw underneath.

    • Unscrew this middle screw using the small 3mm phillips screwdriver.

    • Carefully disconnect the top click pads.

    • Note: Moving each towards its corresponding outer edge makes this easier

    • Unscrew the two screws on the top front of the device.

    • Using prying tool undo the back clip piece shown.

    • Remove two screws in the top back of the mouse.

    • Pry the top and bottom halves apart.

    • This takes a little prying between the outer pieces, which are connected to the top half, and the plastic bottom half.

    • The mouse should now have two separate parts as shown.

    • Using prying tool press against the bottom of each side of the click wheel apparatus to cause it to snap out of place.

    • The end of the click wheel closest to the middle of the mouse is more difficult to remove and requires getting the prying tool down the gap to reach the spot where it is clipped in.

    How do I do it like what motion? I don’t want to break anything.

    • Remove 2 Screws from either side of the click wheel on the lower tier of the PCB.

    • Remove the 3 screws from the top tier of the PCB.

    • Do not separate the PCB from the plastic backing too fast. There is a separate small PCB screwed into the plastic backing which is connected to the main PCB with 2 wires.

    • Remove the screw holding the small PCB to the plastic backing

Really great tutorial! I got my mouse fixed in no time! Congratulations for such a very detailed step-by-step!

My mouse’s left click button has become oversensitive. It double clicks while I drag objects. I could not find a replacement button in online stores. Is there a standard name for the button like OMRON D2FC-F-7N ?

Hakan İslamoğlu -

I actually swopped the internals of a 4000 with that of the 6000 perfect fit. Tanx again

Nic Pretorius -

do you know how to fix the left click button?, mine is not work

Hi, I love this mouse. I have bought my third one, but I feel that the scroll wheel is a little rough when turning. In the past, before finding this manual, I have opened the mouse and had to break the column which holds the screw which is hidden below back traction pad. However, I fear that when I have to put it back on, it will not sit correctly. Is it possible to buy traction pads for this mouse? Or is it easy to put the traction pad back on?

Regards,

KL

Thanks, I was able to deconstruct my friends mouse in the middle of class.

You missed an important part at Step 3. There are two small Philips screws in the back too. Almost broke my mouse because I missed them.
