Power problem with 450

This has happened once to me only. I noticed it started after the lens cover jammed one time. I gently flicked the lens cover shut and pulled the lens also gently when it was fully extended. Seemed to fix it. I had also uploaded the new foirmware at the same time so perhaps that fixed it ? Not sure which. The lens cover system is very flakey - it needs a cover itself as every time you put the camera in a case or in a tight pocket the lens cover gets slightly out of whack and jams. If it happens all the time then sounds like a defect.

It is not the auto-off. It happens about half the time when I push the on/off button - the power goes off on the lcd but the lens does not retract. It's dead. I can get it back on by pushing the on/off button several times and the unit will come back on. I then have to go through the process again. It's a real pain to get the lens to retract sometimes. I would like to think it is something simple, but I can't figure it out. I think it is defect.

The LCD goes dark after the camera has been inactive for a time, to save battery. When that happens, you can easily restore the LCD display by half-pressing the shutter. If you want to, you can turn this off by selecting menu-setup-SleepTimeout and turn it off. (I don't recommend it, though, as the LCD always on will drain your battery).
