If your camera does not respond when you press any buttons, try resetting the camera as follows:
1.Turn off the camera.
2.If you have an optional memory card installed, remove it. (Although removing an optional memory card is not necessary for performing the reset, it eliminates the memory card as a possible cause of the problem.)
3.Remove the battery from the camera, and make sure the HP AC power adapter is not connected to the camera.
4.The Reset switch is in the small hole located above the battery slot, as shown. Press the straightened end of a paper clip into the Reset switch until the switch is depressed, and hold it down for approximately three seconds, then remove the paper clip. The camera is now reset.
5.Reinsert the battery and close the Battery/Memory card door.
6.After verifying that the camera works without an optional memory card, reinsert the card if you removed one in Step 2.
Resetting the camera returns all settings to their factory defaults. Images stored in memory or on an optional memory card are retained.
