What do you mean "sticking" Does it work as it should otherwise?

Did you spill something on it? Do you carry the BB in your pocket?

I've read this problem before. Basically, The best solution (for me at least) is to get some rubbing alcohol & With a cotton swab, Gently wipe the button.

Hope this Helps.

If you have used rubbing alcohol and gotten away with it, more power to you. But I wouldn't recommend it. Rubbing alcohol contains some water, and possibly oils and other ingredients. Rubbing alcohol - Wikipedia, the free encyclopedia

When the scroll ball sticks, it can be loosened up by hold the ball down and rolling it int he direction it is sticking. It can take a while to free up, especially as the sticking begins to repeat frequently.

The ball assembly can be repalced by the user, and it is fairly simple to do. My adivce is search and find video on youtube, watch several a few times, then search for a replacement kit. Don't buy the cheapest you can find. You can probably get a good kit for 10 dollars US or equivalent, plus shipping.

rubbing alcohol is ok to use to clean ur track pad.its easy to evaporate...
if its still underwarranty..take it to the shop.
if its not..u can dis assemble ur track pad and clean the connector pins..it might have corrosion and contaminated by moist due to everyday usage..u can brush the connector using soft bristle's toothbrush or if u have ESD protected cleaning tools is much better....after that clean the track pad ( 8520 is using track pad not track ball) by using alcohol with clean cloth like the texture or eyeglasses cloth...
