Anyone opened up a Logitech MX518 Mouse? - Page 2

**Done_Fishin** · 07-15-2008, 11:24 AM

more likely that you didn't reassemble properly, maybe a part dropped out that makes contact or you have left the front sitting high so it no longer pushes down on the buttons

( the other one was obvious how to put back in)
From what I can tell, what this little bent spring does is make the wheel have that "notched" feel to it as you pull down rotating the mouse wheel. Without this little spring in there that feel is gone and it just rotates freely with out the notching which feels weird to me...but it still work fine without it but I want that back.
So I "Googled" Logitech MX518 Assembly and it brought me to this thread.
Thank you so much for posting these picks of the spring assembly in the mouse!!!

I now have my mouse working perfectly like it came out of the box!!!

I was wondering if you could tell me how you would be able to pick out at what part the cable shorted cause I'm having the same exact problem with the cable.

Normally it's at the point of exit from the mouse right where it bends

best to cut and resolder the wires using th same colour inside the mouse but make sure you use isolating sleeves over the joints to stop wires from shorting again where they have been spliced.

Alternatively , I usually solder to the board after removing the connector and socket

note what colour goes where and only do this if you are experience at soldering.

Not to resurrect a dead thread, but I wanted to register and thank you all for the insight and help in this thread. I just took apart my MX518 to remove cat hair and dust that was clogging the wheel, and when I did, SPROING! Out came little bits of metal. I figured I'd just ruined my mouse, but a Google search turned up this thread and those excellent photos and...well, 15 minutes later, I was back in one piece.

Just a drive-by of gratitude. Carry on. :)

Glad we could be of help .. and that is all what we are about .. someone has a problem, others jump in to give a hand then somewhere down the line someone else has a problem which gets fixed .. it's great that we could be of help again

pass by any time you need anything .. that's what we are here for.

Thank You, Thank You, Thank You.

I opened mine up to clean the wheel, as it was intermitent, and the springs fell of as I was cleaning it. Kept trying to put the 'funny shaped' one back on backwards (wouldn't fit for some reason

). It's now back together and running great. I'll keep the replacement, which I got for Christmas, in the closet as a backup.

<edit> Just looked at the dates. Wow. 2 in one day and both cat hair & dirt on the wheel. This world sure is getting small with this here Internet thing.

Thank you again.

Welcome .. and you're welcome .. the great thing is that you also know that there is an online archive to help you fix your mouse.

Have fun and pop back anytime you need any further help, that's what we are here for

**grimx133** · 12-28-2008, 01:32 PM

While I've never had occasion for this, I'm sure glad this thread is around. The MX-518 is pretty much the only one I use, have 4 of them and another on the way, one of those things that you can never have enough of, best mouse out there.

So, thanks in advance, hopefully way in advance.

**Done_Fishin** · 12-28-2008, 02:47 PM

I like mine too, even though missing a bit (that I never found), it works like a charm but just doesn't click when I use the wheel in the middle

BigGunn · 12-30-2008, 01:05 AM

You guys are lifesavers!

My MX518 was giving me fits working intermittently, so I figured I'd take it apart and see what was what.

Turns out the USB cord had a short in it, so I found one of many old Logitech Optical Wheel Mice I had laying around (dunno where I got em all) and swapped em out. Worked like a dream.

Only problem was that I had these 2 springs and had no idea where they went. Google brought me here and the pics showed me and now my mouse is good as new!!!!!

Plan on keeping the other old mice handy in case the cord should short again!!

**Done_Fishin** · 12-30-2008, 12:00 PM

Musty be an epidemic

but it's great to see so many people have been helped by my original problem ..

Thanks to everyone that contributed to this thread, helping us all and helping all those that come after us.

Hello guys!

I have the same MX518 mouse which a friend gave it to me since the wheel doesn't work properly anymore. I tried cleaning up the interior (thanks to those wonderful pics) but to no avail. The wheel still not working properly. Can someone point me to the right direction?

Thanks in advance

**Done_Fishin** · 09-01-2009, 08:14 AM

when you say not working properly what do you mean. not functioning or doesn't feel right.

my wheel just doesn't click due to a missing spring but it functions well otherwise

max_08 · 09-02-2009, 02:04 AM

Thanks for the reply Done_Fishin.

I mean when I scroll it, the scrollbar just goes up or down by few mm only and takes effort if I want to scroll to the top of the page. I think the wheel is still functioning, but something is wrong somewhere, like the sensor that detects the wheel scrolling isn't sensitive anymore or something.

I installed the latest Mouseware but still no difference.

**Done_Fishin** · 09-02-2009, 08:15 AM

the wheel may not have seated properly or you have somehow assembled it with the timing wheel not sitting between the sensors, the sensor got moved or bent out of position.

it should look like this

the light shines through the slots in the big wheel, Check it's all clean, in position and that the sensors either side haven't been disturbed ie bent out of position. they should be more or less vertical

max_08 · 09-02-2009, 09:19 AM

Hah, it turns out there's some dust on the right sensor which I didn't give attention to clean before. Cleared it up and it works again

Thanks a lot for your time Done_Fishin

**Done_Fishin** · 09-02-2009, 09:53 AM

Glad you got it working .. come back again for any other problems you may face later .. and not necessarily with the mouse

RizlaUK · 11-04-2009, 08:25 PM

Hi,

Does anybody have the order in which the wires need to be soldered to the pcb, my wires came away from white 'plug in socket' and i don't know which order i need.

Thanks in advance

Rizla

**Done_Fishin** · 11-05-2009, 10:46 AM

Did you check the pictures in this thread ?? let me know and if there is nothing there to help you I'll take a photo for you and post it here

**Done_Fishin** · 11-06-2009, 01:43 PM

Haven't heard from you so I took a photo

not my best work

but it should help you.

from left to right the colours are

pin 1 - Black (sheath - thicker lead)
pin 2 - Black
pin 3 - Red
pin 4 - White
pin 5 - Green

the keying is on the "out of sight" side
pin 1 is by the cap on the left
