My trackpad reacts so erratic and frosted

Hi!

I have a macbook pro 15'' 2,53 Ghz mid 2009.

Before 2 moths ago my cursor of trackpad acting so erratic and frosted.Moving crazy, opens finder, minimize widows and sometimes acting deadly slow.This happens for about 15 minutes and after a shut down, everything was fine.

2 days ago the problem appears again.

Same issues, more annoying, uncontrolable and keeps on until now.

A lot of people says many things to fix this in internet but I'll tell you what I have done until now without a reasn.

- I use the original adapter for Macbook

- I remove the battery and try to use Macbook only with the adapter but nothing happens.(By the way my battery's icon on mac says Service Battery I don't know if this related with the problem)

- And finally I put up and inside (I have remove the battery) the trackpad rice for humidity.I'll let you now in a few hours if this recipe works with a Happy End.

So..

Should I have to buy a new with mounting screws?

Should I have to buy a new without mounting screws

Should I have to buy a new without mounting screws and without Cable

None of them?

Is it systems problem to avoid for buying anything?

Also.

I can find a used trackpad-unibody from a 2008 13 or 15 macbook pro.

How should I know if it is compatibly with my Macbook pro?

It will be great for me to solve my problem only with a replacement and not buying anything otherwise it's ok.

So..

That's all.Big story I know for that and Im sorry.

Any help will be good for me.

Open it up and check to see if the battery is swollen and pressing on the bottom of the trackpad.

Hello mayer and thanks for the answer.

As I say in the begging, I have try to use my macbook by removing battery away and use only the power adapter but unfortunately nothing happens.

So you can say that I have try what you suggest.

The next thing I would try is running a virus checker. Also try starting up in Safe Mode by holding down the Shift key and let us know if the problem persists. We need to know if this is a hardware or software problem.

Nothing happens in safe mode.Problem keep on to exist.

I also try to reset nvram but nothing.

By the way rice didn't help me.

I am having a similar problem on a 2012. I'm trying to install a EFI Trackpad version 1.2 & 1.3. update but must take the system back to Mavericks. You might try searching for a Trackpad EFI update for your machine.
