Touchpad went nuts on my 2011 13" MBP

So I was doing my weekly cleaning to my laptops, using the same piece of micro fiber cloth just barely damped. Did my thing trying my best to not get the greasy look on the keyboard and touchpad. Started it back up, I found the touchpad went completely nuts - non responsive, jumps all the screen, created new folders everywhere just dragging the pointer around.

Shut it down, reset PRAM, nope. Eventually it settled down, except a single line (goes the entire width of the touchpad) near the bottom 1/3 on the touchpad was completely dead. As I glide my finger down it would stop for a split second and then continue once I passed the dead zone. Took it to my local Apple store and they replaced the pad in 1.5 hours. My first experience with Apple service, very pleasant. The actual work performed though was pretty sloppy. The tech over-torqued the shims holding the pad, so the touchpad was stuck down and didn't click any more. Shocking how the tech didn't check for that. Like everything else you want it done right you gotta do it yourself. Took it apart myself and retorqued all the screws.

I've always done the cleaning the same way with the same barely damped cloth with water, on couple other MBP's and all PC laptops, never had any problem.

Just an FYI to those who perform regular cleanings like I do.

 

Probably wasn't the water that messed it up. I will say this, you may have voided your warranty taking apart your trackpad. You can get away with some things like switching out your HDD and ram but other things they can tell if you've tampered with a part of the MBP that was not customer serviceable. You should make Apple fix their own mistakes.
