Canon warns of overheating cameras
Canon issued a safety advisory today for its PowerShot A530 and A540 digicams. Seems the area around the battery covers tends to overheat in certain situations. No reports of explosions, but you can get a bad boo-boo on your finger, and battery life will stink.
The problem is a slightly misaligned spring for the battery door, which can cause a short circuit when the cover is closed.
