It appears that some iPad Smart Covers aren't working properly with the new iPad, including older Apple Smart Covers. The new iPad has a slight change in how its magnets work. Apple has reversed the polarity of one set of magnets related to the sleep/wake sensor that turns the iPad off when the Smart Cover is closed. As a result, older Smart Covers, that weren't designed with this change in mind, fail to turn the new iPad off when they're closed.

Mark Booth has more details as to why Apple choose to make the change:

I've learned why Apple decided to use a polarity sensitive switch in the new iPad 3. Some iPad 2 customers were having issues with their iPads entering sleep mode when they flipped Apple's Smart Cover around flat behind their iPad 2. Since the iPad 2's sleep/wake sensor wasn't polarity specific, it could sometimes be triggered from the magnet being positioned at the rear of the iPad. By changing to a sensor that requires the correct polarity, the problem is eliminated.

Booth also notes that Apple is replacing older Apple Smart Covers at Apple Stores for customers who ask. New iPad owners having difficulties with third-party smart cover-compatible cases should contact their case-makers for possible resolutions.

My friend dropped his iPad 2 and iPad 3 on pavement and guess what? iPad 2 not a damn scratch but the 3 shattered. Take what you will out of it.
How scientific. And he must have had his most unlucky day ever, dropping two iPads at the same time at the same place :eek:.

First the thing overheats then it won't charge properly and now smart covers don't work.

This wouldn't be happening under Steve's watch.

If your new iPad is doing all that, take it back.

Mine doesn't even get warm unless I crank the backlight, which I never have a need to do, it charges fine and the smart cover from my dad's iPad 2 works fine on it.

I don't want to jinx myself but I have not had amy problems with my "New iPad".
It charges fine over night. It gets warm while playing Sky Gamblers.
The smart cover that I bought with my iPad 2 works fine.

Bring on the next problem.
