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

    My left click button (the big one) won't click like the right one. It seems stuck or has the slomoes or something. I took out the 4 screws but can't get the top off. What is the secret???

    Can't get the two parts separated. My old Logitech mouse was easy to take apart and clean.

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.

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

The ball wont roll on my blackberry. Help!

The trackball is easily removed for cleaning by just pulling the trim ring around the trackball off with your fingernail. Remove the trackball and clean with alcohol. Reverse the process to clean.

Bold keyboard issues

I had the same problem and have looked all over the internet for a solution, so I know how desperate you can get when your Blackberry isn't working properly anymore. In my case I have found the solution. The cause of the problem might be dirt or moisture underneath your trackball and keyboard.

you have to disassemble your Blackberry completely. So remove the 6 screws on the back with a Torx 6, lift of the bezel, lift out your motherboard and then lift up the trackball cover so you can remove the trackball (see the videos on youtube). Now you can clean the area underneath the trackball, mine was really dirty. In fact, there was dust everywhere inside my Blackberry. I cleaned all contacts and the trackball with a cuetip with some alcohol and used a cotton swab to make them dry again. When I put everything back together, it worked like a charm!!

It's really not that hard to do this, so don't be scared and just give it a try! Follow the instructions on youtube (for disassembling and cleaning) accurately and don't force anything!

I hope this will help.

Trackball only moves sideways not down

It sounds like the trackball has become dirty. If you prise of the silver plastic trackball surround, you can lift out the trackball component and give the small rollers at each side a clean.

Anyone know how to replace the screen on Nikon Coolpix L18?

Once you have all the screws out, seperate from the bottom first and then gently pry at the top sides to break the factory seal. The screen has a thin strip of black tape along the right edge you can pull off. Lift up on the screen to reveal the attached electronic strip attached to the board. It is attached with a grey strip that is hinged, just lift up to remove the strip. Replace with the new screen and reassemble your covers.

Blackberry 8830 wont track down - trackball stuck

This is usually caused by the trackball getting dirty.

Use a q-tip dipped in IPA and clean it. Roll the trackball around and swab the q-tip around to clean.

If cleaning fails then you will need to replace the Blackberry trackball.

Check the following link on instructions on how to do that.

2001 Ford Taurus Door Panel Removal

Make sure you have taken out ALL the screws in the doors. There are screws on the sides of the panel itself going around the door and then there will be one at the door handle. Once you know you have removed them all, place a flat head screwdriver on the outside corner (Bottom closes to door handle) and pry it up until you can get your hand on it and continue around the bottom of the door.

Once you get the bottom out just give it a bit of force and I also suggest you buy some new panel plugs. since the old plastic ones will most likly break or deform.

KidTrac Trackball

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.

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
