Replacing 2015's top case (with only keyboard) with a 2014's top case
I have a MacBook Pro 13" A1502 (early-2015) and I unfortunately damaged my keyboard after spilling a bit of alcohol on it.
I thought on replacing only the keyboard, but since it is too hard to do without any issues, I found an used mid-2014 A1502 top case and I bought it, and it should arrive next week. What I'm planning to do is keep my battery (since it has a larger capacity than the 2014) and keep my trackpad (since it is the force touch one).
Things I read so far:
- The 2015's force touch trackpad takes more space than the 2014's trackpad and it won't fit on the 2014's top case;
- The force touch trackpad needs to be calibrated after replacing it (If true, should it work after SMC reset? Maybe needs calibration only after replacing for a new one?);
- Also read about some people who had a "battery not charging" after disassembly and reassembly.
Are these things true? Are there any other issues I should worry about? If true, any suggestions? Thanks in advance :)
