Same problem here, i upload the pics on my computer, then i turn off my cam, few minutes later try to turn it on, but no success, still have the blackscreen. I try to change the battery, reset it (15s without the battery, another 2 hours but no success), format the memory card (even without the memory the cam doesn't turn on).

Smack it a couple times, gently. You have nothing to lose, AND, I swear it works!!!

I've had this happen a few times. I simply removed the memory card and reinserted it. Usually that does the trick on the first try. On a bad day I've had to do it 3 or 4 times in a row until it just worked.

I had the same problem. Did you ever figure out how to fix it? I called HP and they said I needed to buy a new one.

First I'd try turning the flash off, a manual option on nearly all camera's. Take a couple of photo's without flash, and turn the camera off and on a couple of times then turn the flash back on to auto.

If that doesn't resolve the problem, I suggest going to the HP website, follow links to support and/or downloads and see if there's a firmware upgrade for your camera.
