Introduction

A quick rundown of how to open up the M170's screwless outer casing. This would be the first step before being able to repair any of the internal components.

This mouse isn't held together with screws. This guide will teach you where to find the 3 clips and 2 hooks that hold the top part of the case in place.

Parts

No parts specified.

  1. Switch off the mouse and slide out the bottom cover. This is where all the necessary clips can be accessed.
    • Switch off the mouse and slide out the bottom cover. This is where all the necessary clips can be accessed.

  2. Remove the battery and sticker. There are a total of 3 clips that need to be released. Two are just on the sides. The third one is under the sticker inside the battery's chamber. Logitech commonly hides extra fastening points in a similar place in their other wireless mice.

    • You may need tweezers to remove the sticker easily.

    • We'll release the clips in the next step.

  3. Identify the clips. The plastic of the top cover is a different color from the plastic of the base. You can identify the clips from their color (should be the color of the top cover. Here, they are black). When you've identified the clips, pull them outward/away from the center (see image) to release them. You can use any small tool but the plastic may be a bit soft so do this carefully if don't want to wear the clips out.

  4. After you've released the 3 clips, you should be free to pop the top cover right off. You can help it along by pushing on one of the clips. After the back part pops off, slide the whole top cover forward a little. (There are two more hooks in front of the mouse where the buttons are, that normally prevent you from pulling the buttons upward.) That should let you remove the whole thing.

  5. From here, you should be able to do your repairs on the internals. Interesting thing to note: Logitech switched some of their higher-end mice to high-quality Omron switches. But this, being a $12-ish mouse, seems to use microswitches from Himake. The actuation force feels noticeably higher vs Omron switches. Durability is up for testing and debate. I personally haven't owned this mouse long enough to tell. I like how it was screwless and didn't have any adhesives. It makes it really easy to put back together and it means there are fewer things to lose or keep track of.

  6. To put the top cover back on, attach the front hooks first before snapping the back clips. Press down on the palm part of the top cover gently to snap the back clips into place.

    • Obviously, you'll need to put back the battery and removable bottom panel too. I also reattached the sticker but placed it higher so the clip in the battery chamber is exposed. I wasn't sure if I would need it later.

My mouse wheel is loose so I cannot scroll using my mouse is there a way that one can tighten it since I've opened it n the mouse wheel just came out.

The same happened to mine, so I used a little bit of super bonder to attached again the wheel to the spinning sensor. Problem solved.

Thanks man! Your instructions were very useful. Without them, I don't think I would succeeded in fixing my mouse. The optics sensor was just out of place. My mouse is working perfectly now. Thanks again.

Same! They probably came out from falling on the floor, but putting the loose light back on to the transparent thingy thing definitely did the trick.

can someone tell me where the usb receiver is?

Thanks for demystifying how to open! There is no power getting to the board but I can 't see any break from the terminal to the board so guess I can"t fix it.

Thanks! Releasing the clips wasn’t easy, but it worked in the end. (I have a M171.) Unfortunately, I couldn’t find anything abnormal while ‘enjoying the insides’, so I didn’t manage to fix it. Do you have any suggestion what I should look at, or what broken parts could be fixed? I guess the mouse just fell on the floor too often, and something is irreparably broken.

Thanks ! After release the clips, I found that an internal component was out of place. Now, the mouse works perfect !

add close view of shape of clip/snap on so that user knows which side to press for unlocking three latches.

I have an M170 mouse, but aside from the underside look, mine has NO “3 clips” anywhere. And the top does not come off. I put the battery in and no sign of light so must be something wrong. There are no visible “clips”.

Hi, Before I try opening my M325(hopefully it has similar clips) I want to ask if the issue I am facing is a hardware issue, My mouse registers a double click when I actually do a single click. It is very frustrating as sometime when I try to close an overlapping window , it closes some other application behind it :( . I have tried changing the double click speed setting in the control panel mouse options but no luck.

for some reason the wheel button stopped working, i opened, cleaned it a bit (it had like 4 years of dust, crumbles and hairs) and magically it started working again (not perfectly, but good enough to avoid spending money on a new one or bother soldering stuff)

Man i atach hooks last but its still working perfectly

Thanks! I cleaned the wheel and it’s working now.

I was able to open my M170 with instructions from this page. Very helpful. I was trying to see if I could fix the problem with my mouse: When I scroll using the wheel, the page would quickly jump up when I meant to scroll down. I was not able to fix it. Any help? The left-click, right-click and center clicks are fine, but the scroll wheel is something else. When I scroll, the page tends to jump up and down first before following my scroll. Any help is greatly appreciated. Thanks!

is there a way to reset the mouse?

Mohammed Zameil - Reply

Why do you need to reset it?

Daniele Carminati -

My mouse works fine for 10-15 minutes. then stops working abruptly. It works again a few hours or a day later for 10-15 minutes, and then again stops. I didn’t see anything abnormal on the inside. Any tips?

Maybe some faulty capacitors?
