Picture of 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

Picture of 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

Step 4: Open her up

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

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

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.

I cant believe it worked. After some yelling and time I finally got the damn copper piece into place. THANKS!

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!

The best method I found to get the spring back on was to start by attaching it to the front hook. Next, at an angle I positioned the curved part on the corner of the middle piece and then slid the back of the spring up under the back part. I then just carefully moved everything into alignment by pushing it in towards center. Once I figured this out, I was able to put the spring back on in little time. Mouse works as good as new, thanks for all the tips everybody.

Welp, I followed your instructions to the letter, and the spring broke! And I was as delicate as could be! Even a piece of sugar glass wouldn't have broke so easily!

Don't know what else to say other than I tried my best and won't be able to get another mouse for a while.

Tthanks mate! Great tutor. I have fix LG Performance MX

My version of step 8: 1) put on place rear part of the mechanism 2) then hook the front part 3) after that I used toothpick to push curved tab down on place

The little metal prick took me four hours to install back in its place. My back hurts like hell. Thanks a lot for the guide!

Hi guys,

I want to thank you so much for sharing your findings.

My mouse is a Logitech M505, whose switch started failing after about a year.

First, I want to say that I have had a bunch of mice over the last 30 years, and I can tell you that one of them, an IBM brand was used for many years, and although about 20 years old, still works like new. And it's not the only one. So I suspect those failing switches to be nothing but a programmed failure.

Now the positive part: following jrothermel 's idea,after removing the click case, I visually checked the shape of the switches parts which looked good, so I just cleaned it

1. blew it with a compressor (low pressure: 3 bars)

2. cleaned by spraying a good amount of WD40 with the little pipe

3. blew it with air again to remove the WD40 in excess

4. finished by spraying generously with a good contact cleaner (mine is Bardahl)

It's probably over-fixed, 1 or 2 of the previous steps might do it, I just don't want to open it again very soon. Now it works like new again. The only delicate moment is removing the click case, which is easy with a sharp blade, then a micro screwdriver.

Awesome guide, I could fix my Deathadder following every step. Now I can try with my 2006 World Cup Logitech and my old CM Spawn. Thanks!

Logitech G700 that has been acting up for 2 years fixed in 45 minutes. Such a shame they use the same faulty parts in so many mouses.

Here's an article on how to repair the double click Logitech Anywhere mouse MX. Maybe it will help someone.

I've found my double click issue to have been the result of the plastic that is pressed down on the butten having worn down to make a groove. After filling up the groove with some super-glue the problem is solved!

No need to open up the tiny button. I advise the next person that faces the double clicking issue to check for the groove in the plastic first, and, if present, fill it up with super glue. Then offcourse wait for the glue to completely dry before reassembling.

Worked like a charm on my Logitech Performance MX. Step 8 is indeed the trickiest one, but using your procedure, and with a bit of patience, the thing works perfectly now. Thank you for this great tutorial, frEmn!

i have just looked at what you have posted here and it is very informative i also just watched a guy do the same thing on that tube channel your information is more accurate and pictures give better. you have more vital information into the amount of bending required to fix the problem and you pictures are much more clear. section 6 is a problem i have come up against before those parts are fragile and i would use the smallest device i have available to take it off as snapping completely is a very high possibility.. overall 9 out of 10 and i will do mine this week

This thing solved my problem in 10 minutes. It took a little patience to get back the copper thing but it really did the trick!

I did the re-tensioning of the springs for all three buttons (left, right, scroll) of the mouse and now it works like new. Maybe I'll fix my sister's old mouse too! <3

Oh man, took almost 45 minutes to get that hateful spring back on, but my logitech V550 nano now WORKS PROPERLY!

No more closing Word every time I click on the menu button! (Seriously why would microsoft include this as a double-click function?!)

Totally worth it! Thank you.

Thanks for the brilliant instructions.

Many thanks, dude. Getting the tiny metal spring out and in was a horrible, fiddly chore, so I ended up curving it with a pair of tweezers while it was still installed.

Stopped doubleclicking, tho the button still remains excessively responsive.

I'm doing homework and opening files and my computer is "double
clicking" files, opening files, not holding them when i'm dragging them,
i did a full security scan thinking it might be software (virus,
malware) related, googled it, found this article, and YOU, frEmn, solved my
problems! This 15 minute repair took me 40 minutes because I didn't
read the comments under Step 8: Reinstall tension spring where they
recommend giving the spring a slight curve to aid in putting it in.
That and putting it in with my hand versus a tool seemed to be the
missing information. So for those of you out there who have a $30
wireless mouse that is double clicking, follow these instructions for continued success. THANK YOU FREMN!!

Ha ha
Tell me about it. Tried this on my Razer Deathaddder 3.5 G and Zowie FK. It has worked wonders. I mean, its simply an awesome tip. Cheers to the author, saved me almost hundreds of dollars on new ones. Will keep doin it until the tension thing finally breaks and then get rid of the babe....!!!

Just wondering if we could even get that spring thing somewhere, will not have to buy another mouse for like years together...!!! Coz it actually feels like a new one after doing this...!!!

To the author: thank you! It took me about an hour, with reading glasses and a magnifier, and I had to remove the cover on the other mechanism to get a better look at it, andi tried so many different ways to get that spring back in that I can't remember what finally worked. But I wish I had read all the comments first-- next time I'll try blowing on it first! I kept doing the math-- a $60 mouse that lasted just a year costs way too much at $5/month. I guess I could live with $2/month, which means having to repair it at least once more. Maybe I'll try soldiering in a new switch next time.

So satisfying to fix something good as new rather than throwing it out, and then being able to share my success with folks who get it.

Thanks for your kind comment. I still get a smile every time someone here reports a successful mosuse repair.

Notice how most of the comments here refer to Logitech mice? I did this "procedure" to the left button on a Logitech Performance MX (I have a total of 4 Logitech mice with this problem) and it seems to have helped, but not sure that it completely solved the problem. It took a good hour of fiddling with the spring to increase the tension while still being "clickable". Eventually, I got it pretty much perfect. It is now has noticeably more tension than the right button. While much better, it still suffers from an occasional double-click or will let go when dragging.

Meanwhile, we have over 100 cheap OEM Dell mice out in the wild that pretty much never exhibit this problem. I have another Performance MX along with an M705 here at work with the exact same issue. At home, I have a Logitech G700 with the same issue. Why is Logitech STILL producing mice with this problem?

frEmn (author)  ydoucare2 months ago

I agree. The popularity of this Instructable alone should be proof that Logitech has a manufacuring/engineering problem on their hands.

Anyone have any advice for opening up the microswitch on the M570 logitech trackball mouse? There are tiny little latches on the sides but I'm afraid of destroying the thing if I pull or push too hard.

frEmn (author)  jesse.a.chapman2 months ago

The plastic tabs are very fragile. I broke one of mine the first time I opened the mouse (you can see this in step 6). The best way is with a very small flat head screwdriver or razorblade/exacto knife. Gently pry the tab away from the switch while lifting the cover.

Thank you very much, my M505 is clicking again like new.

saihamaru2 months ago

awesome, my mouse is now working right again XD
step 8 is pretty tricky, but working on it from behind first is easier
so i insert the curved tab and the rear to place first and then pull it a little so the front hook gets in place (don't pull too hard or the plate would bend in weird angle, i had to throw it away and use another plate from one of my broken mouse, phew)
