There are two batteries in each cam. The big one and a small one. Removal of the small one is described here:

Remove this one for at least half an hour. If cam doesn't come up again after reinserting and power up (again: No card inserted) you have to ask for a1ex' assistance unbricking your cam.

Can concur. I experienced a panic moment this morning when my camera went from working fine to not working at all (wouldn't power on). I had been inserting an SD card that contained ML while the camera was powered on. Suddenly the camera was dead. I pulled the small battery, waited, then re-inserted. Camera powered on just fine. SD card now appears to be bricked.
Thanks Walter! You saved me a trip to the camera repair store.
