So I recently opened my laptop and cleaned the heat sink. It was clogged with dirt and the laptop was overheating. Everything went fine and the overheating problem was resolved. But now there's a bigger problem. Windows doesn't recognize the closing of lid anymore. Whenever I close the lid my laptop doesn't go off to sleep/turn off display. I'm guessing I must have screwed something around the hinges. I didn't see any button that gets pressed when the lid is closed. So I'm not sure how the mechanism works. I was wondering if someone could help me with that. My model is 2005ax to be exact. Thanks.
