Display not sleeping after closing lid.
I am working on repairing a MacbookAir4,2. The display will not go to sleep when I close the lid. I can force it to sleep by using the menu. To my knowledge there is not any software issue stopping it from sleeping. I believe it is a hardware issue.
I recently replaced the I/O board I purchased from iFixit. This did not correct the issue.
What controls the sleep function when the lid closes? Sensor? Magnet?
Thank you very much for your help
