Replacing touchpad on Mid-2014 MBP 15"?
Can the touchpad be repaired/replaced by following the instructions for, for example, replacing the logic board, then using the techniques described for the 13" (MacBook Pro 13" 搭配Retina显示器（2014年中期）触控板更換)?
This is a very expensive repair to do on your own here! Sadly Apple used glue to hold the batteries so you'll end up needing to replace them as you well. Yes, you will damage them in the process to get to the trackpad. Here's an older teardown which is basically the same though the whole line: MacBook Pro 15" Retina Display Mid 2012 Teardown. Jump to Step 9 and then to Step 21 to see how difficult it will be.
I would strongly recommend you get your system to an Apple Store for them to fix it as it will be a lot cheaper and a lot less hassle!
Why? My daughter spilled soda on her MBP. College students! We've cleaned all of the keys, but the trackpad seems to have issues. Yes, she can use a mouse; but that's not convenient as she roams the campus.
I know that the battery is glued down. I was wondering if the iOpener (https://www.ifixit.com/Tools/iOpener/IF1...) described in the 13" mid-2014 repair would also work to liberate the 15" battery.
Does anyone know about how much it costs to go to Apple? I chatted with someone and they couldn't give me a quote. But I'm wondering if it's like $200, $500, or $1000? I just want to have enough money when I go to save myself a return trip.
I got the Trackpad replaced once after about 1 year (MBP 15" mid 2014).
Complete assemble incl battery replaced. Costs: just over 700 Euro.
And now, after 3 years having the MBP, the Trackpad is broken AGAIN.
After over 15years using Macs. This was the last Mac I bought.
