Question about Logitech Marble Mouse Trackball

2 Answers

Logitec trackball switches have evidently become dirty on the trackball. I have taken out the 4 screws in the bottom but I am afraid if I force the bottom off I will break something. Is there a latch or catch somewhere to release the bottom. Thanks Charles

Re: logitec trackball

I have a logitec trackball marble mouse usb for one computer and ps2 socket for another, both have 5 screws. To find the fifth you have to feel about on the sticker on the back and poke a hole in it.

Re: logitec trackball

You can lft the top off the mouse. Be careful when you separate the two pieces or the wheel scroll mechanizm will fall out. It did on mine & I'm having a problem with the spring. Hope this helps

Scroll is hesitating.. Will work for moment then button keeps scrolling but screen does not scroll with movement of button... Can this be fixed or do I have to replace?

You can try a few things... Take a clean rag or cloth and moisten it with rubbing alcohol and gently scrub across the scroll wheel to remove dirt and skin oils from the scroll wheel and trackball. Don't let alcohol drip into the trackball body. If that doesn't work, and you are somewhat mechanically inclined, you can turn the trackball over and remove the screws that hold the housing together (some may be under the rubber pads on the bottom of the trackball) open the housing and clean the parts that contact the trackball and scroll wheel with a clean rag or cloth. Blow out any dust or dirt in the housing, Dry the parts you cleaned with alcohol and reassemble the trackball. Use rubber cement on the rubber pads, not model cement or super glue, in case you need to disassemble the trackball again at a later time.

I have a Microsoft Laser mouse 5000. The wheel is dirty and sticks. How to I get the mouse apart to clean it?

I have a similar problem but it was not because the wheel was dirty. The vinyl ring on the wheel for some reason becomes abraded after a few months and expands, slowing the wheel down.

I've opened mine up to clean it. It was tricky, and it didn't improve the wheel much.

If you are comfortable with prying apart plastic cases that might snap if you use too much force, here's how to do it.

1. You'll need a small Torx head screw driver. I have a multi-tool called a Teeny Turner made by Picquic. It has multiple philips and torx heads, great for computer parts. (Note: the heads are magnetized, and usually this is a big 'no-no' for computers, so take care to de-magnetize the heads or be cautious about using it on motherboards, etc.)

2. Open the battery compartment gently with your fingernail and remove batteries. There should be a small torx head screw in the battery tray. Remove the screw and gently pull up on the bottom part of the mouse. Now, gently again, pull the bottom part down while pushing it forward. If it doesn't come off easily, stop and examine the bottom part so that you know how the parts are attached. It's at this point where if you aren't careful enough you can break the mouse.

3. If you've gotten the bottom off of the mouse you will be able to get at the mouse wheel. You might need a pair of needle nose pliers at this point because you will have to gently pry off the white plastic that covers the wheel. Again, examine it in order to understand how it's attached to the base of the wheel assembly. You'll have to hold down the black bottom part under the wheel and pry the white cover upwards. It took me 15 minutes to do it without breaking the assembly.

4. Now for the aggravating part: it's neigh impossible to remove the wheel out of the wheel assembly. It's at this point that I simply used lint-free cotton swaps and a degreaser, and cleaned the wheel by hand.

Like I wrote, cleaning mine only helped a little. If I were to do it again, it'd get a moto-tool and shave off some of the interior of the white plastic cover that surrounds the wheel.

Good luck.

I have a keyboard model Ione Scorpius-35 with built-in do I remove the trackball to clean the contacts? Other trackballs had a ring that you could twist with a pen-point and then remove the...

Afternoon. I read that this keyboard does not have any access to the trackball directly. I guess when cleaning time comes, the whole thing will have to be taken apart.

I am considering the purchase of this keyboard; would you recommend it? I am looking for a keyboard with mechanical keys and a built in trackball.

My Microsoft Intellimouse Trackball rolls but the cursor doesn't

the circular disk that surrounds the trackball and has a little raised part can be turned to left - take it off and ball will fall out- inside are 2 tiny black rubber wheels one to left and one south of that- clean with alcohol on a cloth 9 not soaked) - I scrap them with my nail going across & you'll see gunk come off. Slso turn it upside down & tap it so all dirt inside falls out. wipe all around inside with cloth. Then clean the circle that holds ball. It has to have no dirt on inside area. Clean & dry ball- put back together and make sure to turn the circlular disc till it points to the dot on top. If that gets turned just a little off center it will cause ball to go all over. I've had mine for years & won't part with it. Can't stand chasing a regular mouse around the desk.

Logitec wireless mouse isn't working

If you mean the Infra red light at the bottom of the mouse is not working, then the mouse is defective. If it is under warranty, you can try to get an RMA. If not under warranty, then I'm afraid you'll have to get a new one (would be cheapest).

You'll need to remove the three phillips head screws on the bottom of the trackball. That will provide access to the contacts under the ball for cleaning.

Great trackball. A little more friction than the Kensington Expert Rollerball, which I like as long as the contacts inside are kept clean.

Stiff trackball rotation

Are you sure the metal support nubs have flattened? My experience has been that either they slowly sink into the plastic or that the upper and lower plastic nub supports wear down (which tends to make the ball loose in the carrier assembly). Either way, when the ball gets sticky for me I ensure the metal nubs and the sunken areas around them are clean, then clean the ball with water and find a soft cloth to buff the ball until it is not sticky.

If the metal nubs have indeed flattened you may wish to try removing them and putting them in with the flat side toward the plastic (so you have the round side facing out) - this is assuming they are completely round.

I wish I had a better answer for you. I've have several of the MS TB Optical and only one lasted for a more than a year or so (before the problems mentioned above cropped up). Sadly they are nearly impossible to find and usually very expensive if you can find a new one.

Now if I could only find a way to fix the sudden rapid up/down scrolling mine does occasionally. I've taken it apart and cleaned everything but it still does it :(

Logitech 4 button trackball,

I love this trackball mouse, yet they are very sensitive to wear and trash that causes them to fail. Wal-Mart sells great ones like the Logitech LX3 optical mouse that are not as sensitive and have more features
