The Cat absolutely has a power switch. "Low Power Mode" isn't as low as you might think. The screen is still active and instead of completely blanking randomly moves the text "Canon Cat" around. That being said... I've never known it to randomly access the disk when the screen is blanked. And I try not to stress the power supply by turning it on and off a lot. I probably only use the thing a couple hours every other / every third day. Surprisingly, I've only had to replace the power supply once.
