My MacBook (3,1, late 2007) trackpad button seems to have become very sensitive lately. I don't have to exert much pressure at all... sometimes when I'm barely touching it it will fire.

When I Googled this condition, I saw that - in some cases - a bulging battery could contribute to the issue. So I checked, but that is not the case, here. Could the button housing need cleaning; maybe some stray who-knows-what got in there and is messing things up?

Thanks!

It's hard to say what's going on without taking it apart. The trackpad and button are an inseparable part of the top case. The top case probably just needs to be replaced.

Isn't it glued to the top case? I've never tried taking one apart before to be honest.

The trick with glue is that heat softens glue, but plastic also softens with heat so... this can get into dangerous territory.

Yeah, the top case it's glued. You really can't repair it, but you can take the computer apart and see if there's anything pushing on the top case in a weird way, or see if it's just as sensitive with the top case removed.

It depends on what the meaning "is" is. In my earlier post I should have written what I just wrote above, or otherwise clarified that "it" initially referred to "the computer" before I started talking about the top case -- the top case can be taken apart given enough force and crude cutting implements, but not subsequently put back together.

The left end of trackpad button had 'sunken' somewhat, and was about level with the rest of the top case. But, miraculously, I was able to return the button action to its former state.

I first took the battery out, which allows you to see the contacts at the two ends of the button. I blew a shot of my hot air in there, and put the battery back in. Then, with the computer sitting normally on the desk again, using an extra brush that came with my electric shaver (and not used on the shaver), I got maybe one or more of the bristles down alongside and somewhat under the button.

Whatever that did returned the button to its correct height (slightly above the level of the top case), restored its 'clicky' action, and is no longer as sensitive to touch as it was before.

Can't chalk this fix up to skill, so we'll just go with luck.

If it works there's no knockin' it.

Glad to hear it's better. That's a much cheaper solution than a new top case.

Maybe you'd know it better by the term "electric razor."

When attempting a fix, I always try whatever I can before resorting to costlier methods :)

I actually did consider at first it was an inside joke; I couldn't imagine - unless you were from, say, Canada, where it might've had a different name - someone not knowing what I was referring to. :oops:
