I inadvertently put one of my EM5 bodies in the bag with the switch on a few days ago. When I took it out today, it was DEAD. Totally, absolutely, DEAD. I replaced the battery with a fully-charged spare from the bag and it was still dead. I replaced that one with another fully-charged spare, and it was still dead. Then I tried the battery out of my other EM5 body and everything came to life again. After that, it would work with any of the batteries except the original dead one. These are all Olympus original batteries, by the way. This is a mystery to me. Any thoughts?
