It was "on" by default on my iPad.

New iPad fits my rather expensive Vaja case but sleep/wake is a no go. It's possible they had to move things around due to new engineering but it's curious the Smart covers still work.
Mark Booth said:Yep. This is it. There was a guy on here who did a polarity test and found that the sensor would only react to negative polarity magnets (I think). So that's why we're seeing that some iPad 2 cases work and others don't. The location of the magnet didn't change at all.
And I'm that guy! Although, I'm not sure which pole (positive or negative) the iPad 3 is expecting.
Apple switched to using a sleep/wake sensor that is sensitive to the polarity of the magnet. The iPad 2's sleep/wake sensor didn't require a specific polarity, it worked with both ends of a magnet. Not true for the iPad 3.
Everything is detailed in a post on my blog (complete with HD video demonstration):

It's the magnet polarity. I have the iPad 2 Vaja Libretto case and all it took was to turn the magnet over and it works like a charm. I just pulled back the fabric at the edge of the case and pried the magnet out with a small screwdriver and flipped it over. The fabric residue was still sticky enough to adhere back to normal with no sign that it had ever been altered.
Good job!
