The roller balls on Blackberries are notorious for this. The problem is that they get dirty. It is possible to remove the ball and clean it but that will void your warranty. I suggest calling your service provider and getting it replaced under warranty if the phone is less than a year old. If it is over a year old the warranty is expired already and you might as well take it apart yourself. You can find instructions on how to do this HERE

SOURCE: Roller ball

All you have to do is take a sheet of paper with print on it. Take the battery out of you phone. Next do a figure eight motion with the ball side down on the phone about 10 times. There is something on the ink on the paper that will make this work again. good luck

I can't control where the mouse goes unless I keep working with it. It's all over the place: kensington orbit mouse 64221. I have taken the ball out and tried to clean it.


It's not the ball that's dirty...

Take the ball out and look in the hole. You will see two rollers that control the cursor movement. The ball spins the rollers. These rollers probably have a bunch of gunk/**** on them. Remove the gunk buildup from the rollers and the mouse will work fine (fingernail is a good tool for this). Turn the rollers with your finger to make sure all the gunk is gone. If not, replace it with an optical mouse (no ball).

Hope this helps!

Regards,

Joe

No movement but buttons are working


You may just need to clean it. Open the battery hatch and drop out the ball. Look in the hole where the ball came out of. You should see rollers at the front and side. Usually these pick up gunk dust and crud (very technical terms there ;-]) just from normal use. Sooner or later they build up enough and the ball doesn't move them. Normally one goes out before the other so your mouse only goes up down or side to side.

To fix all you need to do is use a toothpick to scrape off the rollers. These are just plastic so you don't want to scratch them or the gunk builds up faster. So you scrape then turn them then scrape some more. You can then clean them and the ball with some isopropyl alcohol and a swab. Once you have all the rollers clean dro the ball back in, maybe put some new batteries in and it should work again. You may need to press the reconnect button at the bottom.

My roller ball does not scroll down, it goes all other directions but down, it makes it so hard for me to navigate.


take the roller ball out by poping out the silver ring at the top and look on the bottom of the ball and make sure that all of the black rollers will roll and if not clean them.

Roller ball will not work down.


Cleaning the roller ball with a lint free cloth seems to work pretty well. Lock the hand held and then just go to town on the roller ball with the lint free cloth.
