Chosen Solution

had to do some general repairs inside (was replacing misplaced screws from a lazy repairman from an iPhone 4s I was given), and now my power button doesn’t work. I have tried to redo it and the problem is persisting. the cable seems good, and the logic-board also seems good. I have no idea how to fix it. Please help me!

Sounds like.. You need to replace the cable and button, not the metal button on the top. The actual button, connected to the ribbon cable. It’s pretty much the most difficult job, of taking apart and putting back totether, for that phone iPhone 4S Power Button Replacement
