Macbook trackpad problem

I've been having sudden freezes on my trackpad.
There is NO RESPONSE whatsoever after a few minutes of turning it on.

Everything runs fine in the background - I run Paup* analyses in the terminal window - which just keeps right on going. And, I can awaken the mac as it goes to sleep by using the power button... it's just the trackpad that no longer works.

the problem is pretty consistent.

any ideas for a fix would be appreciated.

thanks folks!

 

ooooh

I just realized that my keyboard doesn't do much at all - either.
I can't hit return to do a shutdown when the shutdown window comes up from pushing the power button.

so it's trackpad and keys that freeze. (I can't do force quits either)

 

dammit

thanks I'll try that...
it seems like its a sleep problem - the machine's keyboard and trackpad cannot reawaken.

maybe I'll just stop it from EVER sleeping.

 

diagnostic run from OSX disk

showed no problems after a couple of passes.

this machine is only 2 weeks old.

so I can take advantage of warrenty if the problem is persistent further.

I just set sleep options so that it happens much less... we'll see if that helps any. But when it freezes... NO keys work, not spacebar, not trackpad, not any but the power button.
