Water on my touchpad...

First off, turn it off, don't turn back on for 2 days. That being said, you've already turned it on and seen the effects, so some of the circuits may already be damaged.

 

you can try resetting the track pad.

put the palm of your hand on the whole pad for a 10 seconds, then swipe it off, and it should be all better.

 

Tell me you're kidding? there is no way that works!

 

That's correct. You can't "reset" a trackpad. The newbie that suggested this is wrong.

 

Is that so?

Even with very moist fingers (if you are sweating) or after I've wiped the trackpad with a slightly damp cloth, the input is a bit off. Scrolling fluctuates a wee bit, and moving the cursor is a bit off too.

I wouldn't worry - if the trackpad was soaked and water was literally down the sides of it, then you might have a problem.

But I'd let it dry out and try it again in a few hours or so.

worked on my powerbook, works on my c2d mbp. still awaiting the arrival of my i7

 

The resets never did work on any of the newer multitouch trackpads I've used.

 

How much is a "little"?

It makes sense to just leave it alone in a dry place and let the water evaporate by itself.

 

+1 .. It worked for me .. I am having a 2010 second half mbp .. And two drops of sweat , my trackpad was behaving erratically. I used the vacuum cleaner blower for sometime then left it under the fan for around 4 hours. Later, total ir responsiveness turned to vague. Now i kept my palm on it for 10 seconds twice... and voila.. it starts working perfectly again.. Thanks dude.. !!

 

Thank you for the tips, the 10 second palm in the mousepad worked for me unlike what everyone else is saying, was really scared for a second because me too had restarted my mac twice. My mousepad iw working 100% now, cheers!

 

The same thing happen to me ,i try the hair drier ,i just blow on the touch pad for 5 mints after that ,it works

 

I use water to clean my trackpad regularly. You're likely OK. Just keep it off for a day in some rice and let it dry.

 

That's scary.

I have had this issue happen twice now with my 15" MacBook Pro Retina. For the first occurrence, the erratic behavior started suddenly in the middle of using my Mac, no inciting event. For the second occurrence, it started after I cleaned my trackpad with eyeglass cleaner.

BOTH times the solution was to repair disk permissions and restart my laptop. I'm not too terribly sure why or how cleaning a trackpad causes disk permissions errors but it did the trick. Of course, I would always power off a device and allow it to adequately dry for a day or 2 if liquid was visibly seen falling onto it.
