Introduction: Make Your Mouse Scroll Wheel Move Like Butter
Hate that stiff, clicky wheel on your mouse? Give your mouse wheel a super slick, butter smooth spinning action in 10 minutes.
Since every mouse is different, this hack is mainly about the idea. If you can operate a tiny screwdriver, you should be able to do this whichever way your mouse is put together.
1 computer mouse
1 #00 Phillips head screwdriver (small)
1 X-Acto or utility knife
I am going to do this with both a Logitech USB Mouse and an HP Wireless Elite Desktop Mouse.
Step 1: Find How to Open It
Most mice use a combination of click-together and screw attachments. To find any screws, look for screws under pads, stickers, and behind the batteries.
Under pads: using an exacto top, carefully pry these up and keep in a safe place to reattach later.
Behind stickers: rub your philips head screwdriver over the sticker looking for indentations. These indentations may be a sign of a hidden screw.
The logitech was simple: one screw and the whole thing came apart. The HP will take some tricky moves...
Step 2: Pry Open the Case
Find a seam that looks like where it separates the important parts and pry it open carefully. I prefer a stiff plastic hotel keycard as it does less damage to the soft plastic.
Be very gentle, you don't want to break off any of the plastic tabs in the process.
So now that both cases are open, we can look inside.
Step 3: Identify Wheel Mechanism
Inside your mouse, attached to the wheel is a mechanism that records the spinning motion (often a potentiometer or optical encoder). Usually next to that is a spring that presses against a notched wheel. This is what we are interested in.
The Logitech's spring is right in the middle of the wheel (already removed in picture) and could not be easier.
In an HP Wireless Elite Desktop mouse, the easiest access to this wheel's spring mechanism was right on the top of the mouse underneath the buttons. I was tempted to disassemble further, but they made it rather tricky. Not wanting to break the thing I chose a different method–remove the notches from the wheel.
Step 4: Remove Spring
In the Logitech UBS mouse, life was good. It was a simple easy-to-reach spring that scrapes the inside of the mouse wheel.
Remove it and you are done. Congratulations!
Step 5: Scrape Off the Notches
If removing the spring was difficult, another methods is to trim off the notches that the spring catches on to make the wheel step.
I suggest holding the blade against the notched wheel at a 90° angle to the notches you would like to remove and spinning the wheel with your other hand. Continue until there are no more notches and the wheel is smooth.
