Introduction: Repair Mouse With Double Click Problem

I have a Logitech wireless laser mouse and after a year or so of use, the left click button would double click every time I tried to single click something. As can be imagined, this gets frustrating very fast. So, being the tinkerer that I am, I decided to open her up and see if it could be repaired. Sure enough, It's a pretty simple fix, if you have some common tools and a teaspoon (edit:a tablespoon) of patience. There are some very small parts involved, so you will want to make sure you ware working in a well lit, clean environment so that any parts that are dropped can be easily found. I have now performed this fix for the third time and decided to take pictures this time to share with others who may find this useful. Each time the repair lasts about 6 months to a year before needing to be redone. I imagine at some point the piece causing the problem will break, at which time the mouse will need to be replaced (unless you're determined enough to try and source parts). Good luck with your repair, I hope this helps.

EDIT: There are quite a few comments about the difficulty of step 8. I would advise that you read through some of the comments for various approaches to completing that part of the repair.

Step 1: Remove Batteries

If you are working on a wireless mouse, you will want to first open the battery cover, and remove the batteries from the mouse.

Step 2: Access Screws

On this particular model there are four screws which hold the mouse body together. These screws are located underneath the slide pads on the underside of the mouse. To remove the slide pads, gently pry the edge of the pad up with a small flat head screwdriver and peel it off. They are held in place with some sort of adhesive.

Step 3: Remove Screws

Remove the four screws with a small philips head screw driver.

Step 4: Open Her Up

At this point the top cover should lift off, revealing the mouse's innards.

Step 5: Locate the Click Mechanism That Is Causing the Problem (usually Left Click)

Depending on the mouse, there can be one, or several click mechanisms. This particular mouse has 6, with the left and right click being the main mechanism. The left click is the one causing me problems, and is likely the one you are looking for also. Locate this mechanism so we can continue the repair.

Before you proceed, be sure to notice the very tiny white button located on the top cover. This will fall loose when the cover is removed, and you will want to be sure you retain this piece to be reinstalled later.

Step 6: Open the Mechanism Box

The small rectangular box, contains the part we need access to in order to complete the repair.
To open the cover, use a small flat head screwdriver to gently pry the box cover away from the latch. This will allow the cover to lift slightly until you can do the same to the backside. Be careful not to pry too far or hard as it could damage the cover. The first time I performed this repair, I damaged the cover on mine, but thankfully it still stays in place, so there was no real harm done.

Be sure to retain the small white button to reinstall later.

Step 7: Locate, Remove, and Retension the Spring

This is the key to the repair. You must remove the very tiny copper tension spring from inside the click mechanism.

After you have removed this part, make sure the small tab has a decent curve to it. You can see in the picture how I use the screw driver to bend the curve while holding it down with my finger.

Then bend the tab up, so there will be more tension on it after it is reinstalled. You can see the before and after pictures showing how this will look.

Step 8: Reinstall Tension Spring

This is where the patience comes into play.  This is probably the most tedious and time consuming part of the repair.
To reinstall the tension spring, first attach it to the small hook at the front of the mechanism, as shown in the picture. Then use the flat head screwdriver to push the curved tab into place while keeping the rear of the spring under the small arm at the rear of the mechanism. The second picture shows what it should look like after being reinstalled. Notice the arrows pointing to the spots that need the most attention. You want all three to be correct or the mechanism will not operate properly. 

Step 9: Reassemble the Click Mechanism and Test

Next, you will need to reassemble the click mechanism. First reinstall the tiny white button into the mechanism cover (you did remember to find and set aside the tiny button right?).  The easiest way to do this is by dropping or placing it into the cover with a pair of tweezers. With one hand, pick up the cover  while keeping it upside down so the button stays in place. With the other hand, pick up the mouse body, turn it upside down, and push the cover back into place. Doing it this way will insure that the tiny white button stays in place while the mechanism is put back together.

At this point, before reassembling the mouse, set it down on the table, and give the tiny white button a few test clicks. You should notice that it is making a crisp click sound when pressed, and that it now springs back with more force than it did before. If you are not hearing and feeling a difference, you may need to open the mechanism back up and try retentioning the spring again.

If all seems well, than go ahead and put the mouse top back in place, reinstall the 4 main screws, and put the slide pads back in place. If there is not enough adhesive left to keep the slide pads on, you can add some more. Regular elmers glue stick has worked for me, or a dab of superglue would certainly do the trick.

Thanks for reading. I hope you now have a mouse that clicks properly.

Thank you very much. It took me around 15 mins to complete the fix (on a second attempt).

Actually
you just need to increase the strength of the curved part (the spring),
so you can use a steel rule or whatever to slightly flatten the curved
spring, then put it back on the contacts.

After you flattened the spring, it will be harder for you to put it back on the tiny switch.
I don't have tweezers with me, I used a pair of nose pliers to put the spring back in place. My mouse is like new again.

Hi, thank you very much for the great tutorial - I've tried it and my mouse is working fine. May I suggest that for step 8: Reinstall tension spring, you (1) place the curved tab (which is in the middle of the spring) at an angle on the tiny ledge of the metal piece on the mechanism first, then (2) hook the spring onto the front part of the mechanism, before finally (3) sliding the spring beneath the rear part of the mechanism?

I did not have much luck with the original action series of 2-1-3 until I tried 1-2-3 and the whole spring just slid into place while pivoting on the middle curved tab.

Hope this helps. And once again, thank you!

It did solve the problem in less than a minute unlike before that I always replace the clicker and unsoldering is such a pain, however on my end it sacrifice the clicking feel and sound, does it really goes that way after repair or I did something wrong?

Each time I've performed this repair the clicking returned to normal, if not more pronounced. Not sure what may have happened on your end. I could only recommend opening it up again and having a second look for anything that may be out of place.

I've been having this same problem with my Dell Vostro rig since the time I bought it - the mouse is a wired USB "Dell" branded mouse.


I tried searching for PS/2 mice but found them to be too expensive to be worthwhile. So I looked for USB-->PS/2 converters but none of the 6 pieces I bought off of Amazon worked.

I'm too lazy / paranoid to open the mouse. So I kept looking for alternate solutions. Even used "ClickFix" and another similar utility for a while - but they're, at best, a compromise.

Being an Electronics engineer myself, I wracked my brains for a simpler solution - an had a "Eureka" moment!

Why not use the "right-clicker" which sees much-much lesser use than the left one? All that was needed was to switch the "primary" with the "secondary" button under the "Mouse" setting in Windows 7 control panel and VOILA!

Of course, you gotta be adept at adapting to the switched buttons - but thats me.

Hence I post this "solution" here for other lazy nerds like me :)

Awesome tutorial, thanks a lot! This allowed me to save my G9x which I really didn't want to throw away (haven't found a better mouse since)!


For the spring part, I detached the board from the mice, and holding it vertically so that you can have the spring hanging on the hook, with the index blocking it from the top, that was the method that worked best for me.

Cheers!

Oh thank god. That's the fix I needed for my Logitech Performance MX mouse.

Couple of notes from my run at steps 6-8:

1. A dull Exacto blade worked much better to pry the box open without breaking it than any of the flat-bladed screwdrivers I could track down. Just be very careful to not cut anything (including yourself!).

2. Sometimes the spring doesn't so much require finding as it does catching - mine jumped out as I removed the box and I had to go fish it out of the rest of the mouse mechanism.

3. Somehow I missed that - similar to the center post - there is a groove where the spring fits on the end post that you have to hook around. It doesn't just go around the post.

The idea is to keep the same pin angle, but flattening the curve so the pin is slightly longer. This is what will increase the tension. Also once you know the trick for putting the spring back, it's really fast. First one took 30 minutes to figure out, second one took 1 minute. I've drawn the steps because it might be clearer than having the real pictures, focusing on the important parts

I did step #8 slightly differently, with NO tools and using only my fingers, in around 1 minutes - I'd recommend it this way round

Tilt the back of the spring into position like your #1, and then First lock in the CENTER spring into the right position BEFORE locking in the front. The back part has room to move so this is feasible...once the center part is tensioned in the correct place i swipe my finger quite firmly from back to the front, putting pressure on the front to force that front end into place over and behind the teeny hook on the front part. It fixed in place and has remained perfect! Perhaps it was a lucky try but it was soooooo easy this way! And you are less likely to damage the copper.

Thanks for the diagram! You're the only person who was smart enough to draw a simple diagram. Putting the copper piece back in is really a two-step process.

The second step that I missed, is pushing the curve straight down until it clicks into place.

I followed this instructable to repair my clicker. The first time I did it, I kind of bent my tab, and it worked for about two weeks, before it started double clicking again. I then did it again, and it works like new.


I used the smooth handle of a nail file (anything flat and smooth piece of metal would work) to flatten out the spring clip as much as possible.

I was able to place it on there with my fingers, but I was also using a dental pick in my left hand to help guide the other side on. I found it much easier the second time to use a pick tool (anything pointy, and thin diameter would work). After I used the pick to position it, I slid the pick in between the curved part, and the flat part, and applied downward pressure to push it into the groove that holds it.

The whole thing was slightly curved after doing that (same with the first time), so I use the pick to pull upwards on it in various places until it looked pretty flat. Once it looked good, I put the covers back on using a piece of tape stuck to the outside to hold the button in, as well as hold the cover. By holding the tab of tape, I was able to put it back in without trying to squeeze my fingers into the tight space. Once it was lined up over the bottom half, I was able to use my other hand to press it onto the base to lock it on. Very simple.

I enjoyed your instructable. The images are descriptive. I suggest you take notes from the comments here, and rewrite a little of the text to make it even better though. The process can be simplified.

A footnote for everyone else. Be aware that there may be screws hidden under the stickers. Do not try to force your mouse apart. It should come apart easily. If it doesn't, take something and slide it over your sticker until you feel it give a little. The screws will be hidden in the dimples.

I don't know how to solder, but i found it easier to change the whole mechanism by soldering it off and soldering in salvaged mechanism from another dead mouse, then to put back that tension spring i've done it for 3 buttons on 2 different mouse and i found it impossible to put back the spring. any way thanks to you i managed to save 2 mouses.

Thank you! This worked like a charm! Not only did I get to clean up the lint build up inside, my Logitech G600 MMO mouse is working like new again. No more frustrating double-clicks!

One tip that may prove useful: I used a small piece of tape on the top side of the white button on the black box and pressed gently from the back side (to make sure it was sticking against the tape) to hold the button in place while I slid the black tabbed cover back in place. Once it snapped in place, I removed the tape. No problems had.

I'm not sure exactly what you're asking. The copper piece needs to hold enough tension to keep the contacts from touching when not being pressed.

solenostomus made it!(author)2017-03-10

It worked for me, but I may have damaged the little copper spring. It's very tricky (as mentioned) to fit it back into the mechanism. And very easy to destroy the spring in the process. I may have extended the life of my mouse for a while longer, but possibly not for too long.

Great tutorial

I have a Logitech M705 mouse, which is really great one despite the double click problem that occurred after 3 years of hard work. I followed your tutorial step by step, I faced two problems, one at step 6, until I opened the plastic box, and in the patience test step #8 until I read the comment of AlexandreP11 (Many to thanks to him too) that helped me finishing it.

I used a mobile app as a magnifier to see the tiny components. :-)

Attached the pictures of my trial.

Thank you so much ! You are a genius ! This double click problem was driving me mad !

I own a Logitech M-UR55A optical mouse with this very annoying problem.

It took me quite a while to put the spring back correctly but I eventually succeeded.

I would suggest to take close picture of the spring before taking it apart and also to use a very magnifying glass to do the trick !

Thanks a lot

It took time to fix it (especially the spring part) but I eventually did it !

Signed up for Instructables just so I could thank you! My M705 has been double clicking and hold clicking badly for weeks and I've put up with it because I can't afford 70$ for a new one right now. I finally got fed up (video games are near impossible) and Googled. Knowing myself (I have a tendency to break everything I touch, especially delicate things), I decided to test it on an older Logitech mouse I knew also had clicking issues (basically every time I buy a new mouse, it's because the old one had clicking issues.. So I can't wait to never buy a new mouse again, lol!). It was actually super easy using AlexandreP11's guide. The M705 however was much harder to set the spring, but I persevered, and I didn't break anything! I'm on top of the world! THANK YOU!

Tried this fix on my 3 y/o Logitech Marathon m705. While it did fix the issue, I don't think the problem was actually the spring tension in my case. What I found was that the spring backstop (the hook on the right side of step 8 picture 2) was bent down, preventing the spring from lifting completely off of the contact underneath. Bent it back up, problem fixed!

Step 8 sure was a beast, though. I'm severely torn between trying this with my Performance MX or just replacing the switches.

Thank you so much. This issue was driving me crazy for months!!! Only took around 15min for me.

Step
8 wasn't too complicated. I didn't have any tweezers that weren't bulky
so I ended up getting the back clip in place first with my right hand
and then kind of laid the spring over the top of its clip (don't press
down too hard cause you can undo the tension you just put back into the
spring) and then with my left hand I got the front clip in place and
held it there with my index finger. I then took a pointed object (ice
pick, tiny screw driver) and from the top gently pressed down on the
inside rounded part of the spring until it clipped into place (be
careful not to push it past it's clip or you'll have to start over.

Now my mouse is like brand new and I'm glad because the darn thing was $100.

Thanks again!

Wow...just wow...what a fix!

This took me about 20 minutes to do, but ohmygosh it actually worked. My mouse feels so new! I only replace my left click, but I'll imagine I'll have to get back in there and do the right-click one too.

I did run into one problem that I was able to fix. Upon reinstalling the spring (which...oh...took a while), I actually bent the spring too far, and the white button couldn't reach the spring, and it didn't work :(. I had to take the spring off again (nooo!!!!), bend the larger upper part in an upside-down-v shape a little to get the white button to reach, but it worked! After getting the spring back on and the case back on (tape on the button saves lives, you know), wallah, magic, it works.

I feel so proud for fixing this....haha
