MacBook Pro problem with the touchpad?

I navernoe a curse. After 2 years in Google looking for the same problem but with AIR and gets to your question...

I have this on a plain white MacBook was. In my opinion, getting water in the crack around the touchpad. She was treated by closing and opening the cover or connect a mouse

Had a similar problem on a macbook MB404 black 2008 — swollen battery first, replaced. but still didn't work very well for some reason the touchpad. it turned out that if to put between the battery and is there a certain place piece of rolled paper is quite thin, there is an amazing smoothness, sensitivity and accuracy, but it's worked before through time (seen a swollen battery is something damaged)

The same problem. Arose after the touchpad got a few drops of water. However, I noticed that solves a simple wiping with safetly and alcohol. Apparently on the touchpad accumulates sebum and lost normal contact. And wiping completely solves the problem in time.

I have a similar problem on a white MacBook. again and click on the touchpad, I think it's the same garbage, and it is necessary to disassemble and to clean

The problem was the same, was cured by replacement of the touchpad. The mechanism clicks, apparently worn out. Truth is I have no Proshka and EIR.

The same garbage macbook pro (2011) first small pour himself a touch too itself all pressed run - live your life. then the battery swelled ceased to be pressed (very tightly) now changed the battery the problem with the press is gone, is pressed normally smoothly, but the problem with sumangalam not disappeared. Probably need to replace the touchpad itself.
