praise to Mac Jesus! i fixed my 2011 MBP!
a few weeks back i became quite frisky at work and spilled a sizable amount of Green Machine all over the trackpad of my freshly out-of-warranty MBP. i cleaned it up as much as i could, but it was obvious that some of the juice managed to get through the cracks and probably onto the internals of the device. the mouse jumped and clicked at random. using the Live View in BetterTouchTools confirmed that some of the traces in the trackpad were shorted by the juice, causing the phantom movements and clicks. i was quoted $200 at the Genius bar to get it fixed, which i declined considering a replacement trackpad is roughly half that cost.
after waiting a week for a new trackpad to come in, it turns out i didn't even need it. first, a big Fuck You to Apple for the tri-wing screws for the battery. i could've had this cleaned a week ago if Apple just bothered to use a more traditional screw to secure the battery.
first observation: after a year of use, there is a disgusting amount of dead skin/white powder on the top side of the battery. actually, depending on whether you've ever opened the underside of your MBP before, you're likely to find a lot of dead skin and dust on the underside aluminum shell as well. i cleaned that up with rubbing alcohol and compressed air.
the Green Machine leaked pretty far inside - there was sticky residue along the sides of the trackpad cutout, on the topside of the battery and even to the middle of the trackpad where the connector lays. if Apple didn't design the trackpad into a separate 'chamber' of the chasis, i would've shorted my motherboard easily. thank you, engineers.
the trackpad itself appears to be sealed and impervious to this type of liquid damage, though. the circuitry that measures the touch input is glued to the glass on the top and a metal plate on the bottom. its rigid and has zero flex. while there are cutouts on the metal plate that exposes some of the circuitry, it's all coated in a brown plastic and seems like it'd be somewhat resistant to the type of spill i made.
i took 90% alcohol wipes and cleaned the areas the juice reached. when i reconnected it, there was zero improvement. i disassembled everything again, except this time i primarily used q-tips soaked in rubbing alcohol to attack every potential area where juice could've seeped in - i soaked each edge of the trackpad, the metal cutouts and the connector and cable in rubbing alcohol multiple times. THAT seemed to do the trick, and the laptop's been running for nearly a full day without any phantom movements or clicks. success! bonus - the clicking action on the trackpad now feels as smooth and even as it did when i first bought the laptop.
now i have to decide whether to keep the extra trackpad as an insurance or to return it...
I have a 2010 top case coming in... (Used a Magic Eraser to clean up my keyboard, I guess it wasn't dry enough)
Where did you get a tri wing screw driver?
