Originally posted by Neville I had a similar experience recently while visiting a local game reserve.
My K-5II would power up momentarily and then shut down when I tried to wake it up to take a shot. I swopped the battery, but the problem persisted. Now I was panicking, as it was the only camera I had with me.
Then I noticed that the cover for the sd card was not closed properly, so I closed it and all was well again!
I had a similar egg-on-face moment a couple of days ago, with the "company" D80 that I have to use at work. Grabbed the camera to shoot something (boss breathing down my neck about it...), turned it on, got it to focus, then nada, zip, zilch. Little beeps, no shutter. <bad language>. Turned it on and off a few times, no joy. Starting to sweat... then I (finally) looked at the LCD and saw the "E" code. No card in the camera! I had removed it to dump some previous images and never took it out of the reader... fortunately nobody but me knew what the "problem" was that I "fixed"...
