My computer's trackpad will not single-click. Any attempt at single-clicking produces double- or triple-clicking.

As you can imagine, this renders it borderline unusable.

No, just pretty much unusable.

And Adam can't figure out why.

It's a MacBook, not pro, not aluminum. Yes, it's a few years old. No, I cannot afford a new computer. Yes, I have my old backup laptop, but I can't haul both on my trip, and the old one doesn't have enough room for my in-progress writing - we never did figure out the memory problem on it, and now we just don't have *time* to figure it out.

Using a USB mouse for now, but that's really unwieldy, and will be even more so on the plane.

Any ideas?

(Please excuse me if this accidentally posts eight times.)

EDIT: Have checked for battery bulge, and it isn't that. The trackpad controller is beneath the battery, but we don't know enough about it to mess with it; don't want to make things worse! We can try canned air when I get to Florida. Adam blew on it for now, and it is now not double-clicking *every* time, so hopefully canned air will clear it right up.

Other than checking the trackpad settings (double-click speed, check if "drag lock" is on or not, and try "ignore accidental trackpad input"), there's not much else.

Personally I turn off trackpad clicking and just use the button, but it's personal preference.

(yendi replying from 'song's machine.)

Alas, neither of those are it. The problem actually is the button; 'song doesn't click from the trackpad itself. And we've verified that things work better with an external mouse, fwiw.

Maybe your button is dying, or the click sensor under it.

What happens if you turn the double-click speed all the way up? That'd require you to hit it faster, but it might reduce how many "clicks" it's sensing when you hit it once.

Tried that first thing, alas, but no luck.

Damn. I'm out of tricks then. I have no idea how to take the top case off and such, but if you're willing to try it I'm sure you could find instructions online. Maybe there's something stuck inside or something you could clean out.

Any chance you (or someone else) accidentally changed the preferences under Keyboard & Mouse?

Concur. I misdiagnosed battery bulge as trackpad failure once, and narrowly averted leakage.

Although, at this stage in the laptop's life, it's more likely something physically lodged under the button and causing problems. Even dust and skin oil accumulation can get problematic.

Is it a trackpad with or without a button?

I've had the same problem forever with my laptop's touchpad which uses buttons. It wasn't that big a deal because I prefer a usb mouse all the time, but last night I got extra-specially irritated at it and finally blasted the hell out of all the button creases with some canned air. Now it single-clicks again...

Clearly only works if it has a button. :/

I second this... it has fixed laptop trackpad buttons for me in the past. :)

Canned air ftw!
