Fixing the Logitech MX Ergo Double-Click Issue.

Picture it, NY, January 2021. Covid’s still running rampant. I’ve been working from home for nearly a year at this point (zero complaints). I decided to treat myself by purchasing one of these Logitech MX Ergo trackballs on Amazon. I’ve been using a trackball for decades, ever since my first apartment with a tiny desk and not enough room to comfortably mouse around.

So here we are about 4 years later, well outside a warranty replacement window and it has this pesky problem where it will randomly double click. I do a quick search online and discover via reddit that it is a common problem on specific Logitech mouse and trackball devices. Now as I’ve got no desire to drop another $100 on a new one, and I found a handy blog post

I go ahead and order a new 4 pack of Kailh GM 8.0 (pro-tip, do not do what I did, these switches are garbage). I take the trackball apart, replace the switch, and for the first day not only is there a satisfying new click – there’s no more double click issue. Then I hit day 2. It’s not double-clicking anymore, it’s more randomly UN-clicking.

Back to the Internet I go… I find another Reddit post which explains that the Kailh’s are actually prone to problems, but the OMRON D2F-01F is made in Japan and solid. So off to Amazon again and I order another 4 pack. Again the trackball comes apart, switch is swapped, and I’m here at day 1. It works perfectly, time shall tell…

This document assumes you are familiar with working with electronics, disassembly, de-soldering, soldering, and generally not making a mess of things on your work bench. Anything with a red circle is likely something that needs to be disassembled here per the instructions. If you follow my instructions and break the thing, this is your only warning.

This is strictly for educational purposes. Attempt repair at your OWN RISK.

Tools Needed:

Here’s the trackball, start by flipping it over, switching it OFF, removing the magnetically attached base plate, and removing the trackball (just poke it out with a pen).

Next, remove the 6 TORX T6H screws and set them aside. The two top and bottom of the trackball will come apart easily now but do NOT just pull them apart, there’s a ribbon to detach.

The tan clip (circled in red) pulls up slightly, and then the ribbon can be removed easily. If it doesn’t easily slide out STOP and make sure you have freed up the tan clip!

Next remove the battery, the white clip is its connector to the circuit board, and 3 PH00 screws hold it in. Gently pull the white connector from the board.

The scroll wheel snaps in at the top, gently pull it up to detach it. The PH00 screw holds on the small board on the left which is attached to the main board by a small ribbon (do not try remove the board, we just want to move it out of the way so we can remove the trackball casing).

Two PH00 screws hold the trackball casing in, remove them. Also gently pull the tan clip up for the ribbon cable, and remove the ribbon cable from the main board. If it doesn’t easily slide out STOP and make sure you have freed up the tan clip! Remove the trackball casing and set it aside.

Next, remove the 4 PH00 screws that hold the main board to the base. We have another ribbon here to detach as well, with a white clip. Gently pull up that clip and slide out the ribbon. If it doesn’t easily slide out STOP and make sure you have freed up the white clip! You can now separate the main board from the base.

On the left is the top view of the trouble switch. The original was an OMRON like the new one. I replaced it with the Kailh and it lasted a day. So now I’m removing it by de-soldering the 3 solder points below it, removing the bad switch and soldering in a new OMRON.

Here is the new OMRON switch clearly labeled with JAPAN. Assembly is the reverse of dis-assembly. If you’ve gotten this far, you should be able to get it all back together and for $10 ($2.50 a switch) have a perfectly functioning trackball again. Good luck!

Devotional – John 1:1-5

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made. In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not [a]comprehend it.

John 1:1-5

John starts as Genesis did, and reveals that in the beginning was the Word, the Word was with God, and the Word WAS God.  His Holy breath made that Word flesh, the completed creation that is God in flesh, Jesus Christ.  Jesus and God are One.  Know Christ, know the Father.  Know the Father, and you will know Jesus Christ.

He made all things, nothing has been made that was not made by Him.  He is the light of Creation and Life, the light of all men.  No darkness could ever overcome the perfect light of Jesus Christ.

Devotional – Revelation 4:5-11

And from the throne proceeded lightnings, [a]thunderings, and voices. Seven lamps of fire were burning before the throne, which are the[b] seven Spirits of God.

Before the throne there [c]was a sea of glass, like crystal. And in the midst of the throne, and around the throne, were four living creatures full of eyes in front and in back. The first living creature was like a lion, the second living creature like a calf, the third living creature had a face like a man, and the fourth living creature was like a flying eagle. The four living creatures, each having six wings, were full of eyes around and within. And they do not rest day or night, saying:

“Holy,[d] holy, holy,
Lord God Almighty,
Who was and is and is to come!”

Whenever the living creatures give glory and honor and thanks to Him who sits on the throne, who lives forever and ever, 10 the twenty-four elders fall down before Him who sits on the throne and worship Him who lives forever and ever, and cast their crowns before the throne, saying:

11 “You are worthy, [e]O Lord,
To receive glory and honor and power;
For You created all things,
And by Your will they [f]exist and were created.”

Devotional – Revelation 4:5-11

The throne of God exudes His power in the form of lightning and peals of thunder.  The seven lamps of fire, the seven spirits of God, represent the perfect completeness of God, His Holy Spirit.  Four creatures full of eyes, angels, among the crystal like sea of glass ceaselessly worship and proclaim the Lord.

As they give glory to God, the 24 elders fall down before God in worship, and cast their crowns at His feet.  All praise and worship the eternal and living God!

Devotional – Revelation 4:1-4

After these things I looked, and behold, a door standing open in heaven. And the first voice which I heard was like a trumpet speaking with me, saying, “Come up here, and I will show you things which must take place after this.”

Immediately I was in the Spirit; and behold, a throne set in heaven, and One sat on the throne. [a]And He who sat there was like a jasper and a sardius stone in appearance; and there was a rainbow around the throne, in appearance like an emerald. Around the throne were twenty-four thrones, and on the thrones I saw twenty-four elders sitting, clothed in white [b]robes; and they had crowns of gold on their heads.

Devotional – Revelation 4:1-4

The throne room of heaven.  Johnis called directly into the throne room of heaven by a voice bold and powerful as a trumpet blast.  He was in the Spirit, fully, to witness a glimpse of what is coming next for all who believe.

He saw One on the throne, he vividly describes the colors of the glory he sees, Jasper (red), Sardius (blood red), rainbow (a reminder of God’s covenant with Noah in Genesis 9:11-17), and emerald (green).  He sees this in the spirit, as likely no flesh could withstand such a sight!

Around the throne are 24 thrones with 24 crowned elders, representing those who have run the race and achieved victory through Christ (thus the crowns).  My mind can’t even come close to imagining what John sees here, the only word that I can think of here is “glory.”

Devotional – Revelation 3:14-22

14 “And to the [a]angel of the church [b]of the Laodiceans write,

‘These things says the Amen, the Faithful and True Witness, the Beginning of the creation of God: 15 “I know your works, that you are neither cold nor hot. I could wish you were cold or hot. 16 So then, because you are lukewarm, and neither [c]cold nor hot, I will vomit you out of My mouth. 17 Because you say, ‘I am rich, have become wealthy, and have need of nothing’—and do not know that you are wretched, miserable, poor, blind, and naked— 18 I counsel you to buy from Me gold refined in the fire, that you may be rich; and white garments, that you may be clothed, that the shame of your nakedness may not be revealed; and anoint your eyes with eye salve, that you may see. 19 As many as I love, I rebuke and chasten.[d] Therefore be [e]zealous and repent. 20 Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me. 21 To him who overcomes I will grant to sit with Me on My throne, as I also overcame and sat down with My Father on His throne.

22 “He who has an ear, let him hear what the Spirit says to the churches.” ’ ”

Revelation 3:14-22

The lukewarm church is blind to the state of itself.  Its worldly wealth and comfort has led it to be neither hot nor cold.  They may need nothing of the world but that has also evicted their need for Christ as He vomits them from His mouth.  They make Him sick!

There is no salt or light to be found here.  They must be zealous and repent, He commands them as He stands at the door knocking and waiting that they may let Him back in to dine with them.

Devotional – Matthew 5:4

Blessed are those who mourn,
For they shall be comforted.

Matthew 5:4

I have mourned for lost loved ones.  I have more mourned failed relationships.  I’ve even mourned when my car died.  None of that is what I mourn the most for.  I mourn for those who have yet to know Christ, or have willfully turned from Him.  I find great comfort in knowing that His patience is greater than mine! 

His grace is given freely to we who even saved do not deserve it.  He is all powerful and none are beyond salvation through Jesus Christ.

Devotional – 2 Corinthians 1:3

Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort,

2 Corinthians 1:3

Here Paul reminds the church, all of us in fact, of the source of all mercies and comfort – indeed our very salvation through Jesus Christ – God the Father.  Praise Him for all He is and all He has done.  Blessing Him is a great way to remind us who He is.

Devotional – Psalm 34:18

The Lord is near to those who have a broken heart,
And saves such as [a]have a contrite spirit.

Psalm 34:18

This bit of Psalm 34 reminds me of the day I filed for divorce in 2013.  I’d left the lawyers office after doing the paperwork, walked into my old Catholic church during a weekday service, sat in the back and wept.  I couldn’t really hear what the priest had been saying as I focused on the floor with my head in my hands.  

I do remember feeling God’s presence there though.  While I wouldn’t give my life to Christ for another 6 years, the peace I felt on that day was what I had been seeking when I stepped into the non-denominational church in my town in early 2019.  Finally seeking Him for His purposes, I’d be saved by Christ only a few weeks later.

Devotional – Romans 5:1-5

Therefore, having been justified by faith, [a]we have peace with God through our Lord Jesus Christ, through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God. And not only that, but we also glory in tribulations, knowing that tribulation produces [b]perseverance; and perseverance, [c]character; and character, hope. Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us.

Romans 5:1-5

We have been justified by faith in Christ, thus we have peace beyond all understanding with God through Jesus.  By faith we have access, undeserved and abundant, to God’s favor, His grace, which leads us to stand and rejoice in hope of experiencing the glory of God.

We see His glory in our tribulations as we seek Him in them, and cry out to Him, persevering, building godly character, and placing all hope in Him to see us through.  The hope in God will never disappoint because it is a result of the love of God that has been poured out in us through His Holy Spirit.

Tribulation serves to build our relationship with Christ and humble us in His presence as we fully depend on the Father to walk with us and guide us through them.

Devotional – Hebrews 12:1-3

Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, looking unto Jesus, the [a]author and [b]finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.

For consider Him who endured such hostility from sinners against Himself, lest you become weary and discouraged in your souls.

Hebrews 12:1-3

As Christians, all are a witness to our walk, every word and deed.  I have heard it said that we may be the only bible anyone may read, so we must run this race well.  Our full focus must be on Christ in whom our faith is complete, and endured the cross to the point of death so we may live life to the full.
