Why doesn't keyboard and trackpad work after battery replacement?
I replaced a dead battery on my MacBook Pro and now the keyboard and trackpad aren't working. The battery works fine, but the fans come on like gangbusters and won't go off. I can use a remote keyboard and plug in mouse but the fans blow and blow. I did my best to reconnect the track board ribbon but clearly something is amiss. Help!
Ist dies eine gute Frage?

Replaced battery. Responds to startup key. No other keys nor trackpad work at all. I can force shut down using command-shift-option-power but nothing else. Replaced ribbon with another used ribbon with no difference.

I had same issue,
Replaced ribbon no help. The ribbon connection at the track pad end was the issue for me. removed ribbon from connector, then used a flat ended plastic tool to compress connector (push top towards circuit board) and making a tighter connection. reassembled and works again.

Had the same issue – after carefully replacing the battery on a A1052, the keyboard & trackpad wouldn't work no matter how I tried to reconnect the ribbon at both ends. The fans didn't go crazy, as in several comments here.
Replaced the ribbon (bought a new one), and everything is ok now!

@zoliaxk where did you get the ribbon?
