I assume the problem occurred with the lens on the camera when you turned it off? I'm curious what would happen if you put the lens on the body after it was turned off and you didn't turn it back on for a few days. Would the body be drained in that situation? That wouldn't prove too much but might suggest a glitch that the presence of the lens when you power down prevents the body from powering down correctly. It would be interesting if others with your camera and lens could try to recreate the problem. There very well might be an issue, it just doesn't show up during the "normal" diagnostic. There could well be a compatibility issue that was just never tested for.

Lens and body are long gone. Newer Tamron lenses don't suffer this issue. Quiz time...When is a Canon body truly "off"? Answer...Only when the battery is removed!
