Nothing related to Windows 8 this time.
From 5 years ago, I’ve been using mouse called Logitech MX Revolution almost every day. I’ve thought of getting new model, but didn’t find one that interests me. One of good thing about MX Revolution is, you can adjust and switch to mute using scroll wheel of left side of mouse.
There were no problem using for long time, but from couple month ago, single click became double click and dragging becomes aborted frequently. File opens unexpectedly, and file gets dropped off where I did’t want to.
Well, since this mouse is no longer usable, I was looking for replacement. But, no new model has same functionality I wanted. However, I found that many of the similar symptom was reported by other Logitech mouse users, where single click becomes double click. This is caused by chattering of mouse switch, and can be fixed by replacing switch part.
Good, then let’s replace the switch. Recommended switch part was D2F-01F from OMRON, and I bought 5 of them for future use. Each costs about few dollars.
This time, problem was for only Left side click, so I replaced switch on the left side.
Screw is 4 places, under the sheets. Screw is special torque type screw, and you will need T-6 screw driver.
Flex cable connects circuit board and upper switch, so you need to be careful not to cut the cable.
Unscrew wheel screw. Screws inside mouse is plus screws.
Take apart battery, and battery holder.
Now, you can lift up the circuit board.
Switch is soldered to circuit board, so you have to use soldering iron to take switch off. Since circuit board is soldered with battery charging connector which is fixed to mouse cover, you can’t take circuit board apart. You need to work by lifting circuit board.
This is due to my bad soldering skill, but it took while to unsolder switch. This was hard part, and I finally took apart by cutting legs, and pushing toward circuit board.
I melted cover a bit while unsoldering…
After removing old part, place new switch and solder. Be careful with direction.
After soldering, assemble back.
Now, double click and dragging is back to normal state, and everything is working fine again. I can now continue using this mouse until new model that satisfies me comes out to market.
