replacing uppercase MacBook Pro early 2011
I spilled coffee over keyboard. So the keyboard didn't work anymore.
With the instruction on ifixit website, it was quite easy and nothing complicated. Just needed proper tools and took time for me. Because it was the first time that I repair my computer by myself.
The most difficult part for me was to get in and out keyboard cable. Be gentle with it.
