Does not go to sleep when lid is closed

Hello,

After replacing the battery on this computer, the computer does not go to sleep when the lid is closed. Everything else works fine. Maybe it is a damaged hall effect sensor?. What would most likely have been damaged in the process of replacing the battery that would have caused this? How would I go about fixing it?

Thanks!

Answer this question I have this problem too

Is this a good question?

No. No software settings were changed after the battery was changed, including the display settings. It used to go to sleep before.
