Lens stays in and camera will not power up.

Resetting is only useable from within the menu system. There's no actual hard reset. All it does is put the menu system back to factory standard. Forget Alkaline batteries, use Nimh type only and make sure they're fully charged. Quite often reformatting the card in a computer can muck things up. It's best to reformat in the camera. If you have a friend with an olympus ask him to format your card for you and see if the problem clears. Also make sure the gold contacts on the card are clean. Often a quick rub with a pencil eraser will do the job but make sure you remove any rubber pieces after. Personally I use just a piece of ordinary printing paper. If you are still stuck try inserting and ejecting the memory card as fast as possible about a dozen times, you could have dirt on the internal contacts. Making sure the camera is off of course.

Hello, first of all try one thing, remove the memory card from camera and try to turn the camera on with fresh battery. if problem still remain try with another memory card. if your problem not fixed reset the camera. still not fixed run to olympus shop. good luck....
