The iPad says it needs to cool down under too much sunlight

Early complaints from iPad users mostly focus on reported reception issues with wireless routers. On top of that, however, we’re hearing stories of other problems plaguing Apple’s inaugural multitouch tablet.
Apparently, some iPads are malfunctioning when users expose them to too much direct sunlight. According to ZDNet, some overheated iPads refuse to work, greeting their users with a simple message:

iPad needs to cool down before you can use it.

CNET reports that some users have seen this message while operating their device at relatively mild 70 degrees.

Christian’s Opinion

Well, this doesn’t surprise me. I own an iPhone 3G and I’ve noticed a similar phenomenon that’s especially evident during the summer. When the outside temperature tops 95 degrees, even less, you begin seeing a noticeable lag and system-wide slowdown. As a result, it often takes 15 seconds or more just to wake your device from sleep. According to Apple, operating temperature for the iPhone 3G is between 32 and 95 degrees Fahrenheit.
Anything warmer and your phone will decrease its CPU speed, clock cycles, and screen brightness in an effort to cool down the silicon. And what about the iPad? According to official system specs, the device requires the same 32° to 95°F (0° to 35°C) range as its phone counterpart. That being said, the case of iPad overheating at direct sunlight is probably a non-issue, no matter how you spin it.
