Hi, I replaced keyboard on my MacBook Air A1932, I have a problem when I close the lid of the laptop and then open the screen, it does not turn on, but while the keyboard is highlighted. Can you help me out this problem?
Ist dies eine gute Frage?

This sounds like issue with sleep wake functions which are integrated with hall effect sensors in the display. These signals also run through the trackpad the device knows to wake up if the keyboard or trackpad is actuated when the display is open. I would make sure a few connectors are seated properly and fully. In order of my suspicion of the issue:

The new whole top case keyboard was with the microphone installed.
@Dmt A What happens if you reinstall the original top case? Does the issue persist? There could be an issue with something in the replacement top case.
Hall sensor appears to be in speaker on audio board side.
Where did you get the information that the sensor is assembled with a microphone?
@Dmt A There are two. One is on the speaker, as you mentioned. And one in the top case in the mic assembly.
I edited better pictures into the original post. Ultimately the one from the mic ends up running through the trackpad cable. Which could also be the issue. I would make sure the cable is seated properly. The open signal is sent through the trackpad cable as well, so if it were shorted, or punctured that signal might not get through.
