So how do I fix the stiff left button issue?
Logitech v470 bluetooth cordless laser mouse. Released August 2007. Also includes scroll wheel and side to side scrolling. Current Part Numbers : 910-000314 (blue), 910-000311, 910-000969 Older Part Numbers : 810-000953 (black), 910-000299 (white) This fantastic mouse suffers from a small design flaw which, over time, makes the left mouse button virtually unclickable. Here's the problem & how to fix it.
You'll need a small Phillips screwdriver. A size 0x40 works nicely. (Picture 1) Also get a penknife or Xacto knife to peel the gliders off, and some superglue of some type.
To view the pictures larger, just single-click on them. They will zoom for a better view.
(Picture 2) Remove the battery cover and the batteries.
Remove the screws next to the + and - symbols. The other screws will be removed later.
(Picture 3) Lift the edge of the foot gliders with a knife. Peel the sliders off. When you remove them, the adhesive will be useless. Rub it off with your finger and discard. Set the gliders aside.
(Picture 4) Remove the screws that were hidden by the gliders.
(Picture 5) Lift the upper shell away from the base.
(Picture 6) Remove the two remaining screws that hold the blue top to the rest of the shell.
(Picture 7) These screws are smaller than the four screws removed in prior steps. Keep them separate from the other four.
(Picture 8) Push the 2 blue tabs toward the centerline of the mouse, using your fingernail or small screwdriver. This will release the blue plastic from the black shell.
(Picture 9) Wiggle the blue top off of the black shell. It won't take much force at all.
(Picture 10) Look at the black shell. The problem is that the battery contact has lifted out of the plastic, preventing the left button of the blue shell from being depressed. The top edge of the metal should be flush with the black plastic.
(Picture 11) Push the metal back down into its slot. I used the side of my screwdriver.
(Picture 12) Apply the glue. (Picture 13) I used Krazy Glue with the brush applicator. This type seems to have a longer working time and took about 5 minutes to dry to the touch. I made myself a nice adult beverage while I waited.
(Picture 14) I put the glue in two spots, which are the glossy areas in the picture.
Let the glue set if needed, and reassemble in reverse order. You will likely have to superglue the gliders back on after you put the screws in the bottom of the mouse. Make sure the glue is dry before setting the mouse down on your desk.
Done! The mouse should have a much nicer "clicky" to it now!
1. unscrew both philips screws inside the battery compartment (the ones that are below the batteries). There are two more under the front glide-pads, these go off easily with a sharp knife. Now open up.
2. in the top cover, unscrew both remaining screws. Then release the blue part of the cover a bit by pressing the two latches in the middle. Now shift the whole blue cover forward (button pins must go past the plastic holding them back.
3. Look at the black plastic top cover. You will see the metal plate of the battery terminals. The part below the left button will be lifted a bit (or may already have moved down by all the handling so far. Push it flush with the plastic top, and put some superglue between metal and plastic to lock it in place.
4. reassemble. Done
If your left click is taking command properly it would be due to carbon inside left click button.
After using long time it creates problem.Simply open mouse like as shown at up side. Take a small drop of petrol or thinner into button and continuously click by finger and repeat it twice or thrice. Now leave your mouse for dry liquid. Screw your mouse and use it. It will work fine.
I have fixed many mouse like this in my home and friends.
if it's really bothering you, like my apple keyboard was after a soda ended up on it.... WD40..... Depending on the cause of the problem, may fix it.
i used a significant amount, also cleaned the keys which are nice and white again, aluminum parts too..... WD40 is great....... it's not an oil per say......everyone uses it for that...... al thou it has a bit in it.....it sucks the moisture out of things and cleans.......in all cases I have used it for, is harmless to electronic components (maybe some types of rubber etc won't like it, haven't had a problem yet).
I used the point of a pair of drawing dividers to engage in the hole of the inner battery terminal plate connection and gently levered it downwards away from the outer casing.
This has solved the problem – time will tell to judge how affective this repair is!
Thanks for the hint, I didn't suspect the the metal plate but that was it indeed! For me, it was a right button issue though, it would hardly work... I filed the offending part with my dremel so it always sits flush or below the plastic (there's slight movement of the plate/bracket) and tightened the holding tabs. Been using the mouse all day long without issues so I'm a happy camper!
Your diagnosis was perfect for my V470 mouse. Based on that all I needed to do was wedge the tip of a small flat blade screwdriver above the metal contact plate and press it down, moving it back in proper place. No disassembly required.
