@rem736 - I've had the same problem while transporting my M92 in the standard Onyx leather case in a messenger bag. I think the problem is the power management bug Mono referred to, in that the device sometimes turns itself back on after manually being put in standby mode. I've actually observed the device doing this while sitting untouched on a table, so I know for a fact it's possible.
I haven't been able to figure out the exact conditions that trigger the bug, though.
