I just picked up two G10 units and I am ready to bring them back. They stopped going into the poster save mode so I discovered there was a firmware update. I updated the firmware (i got the updater for my mac) and they went into the power save mode but only once… each subsequent time on both units that i left them for more than half an hour, they did not go into the power save mode… I have updated the firmware several times to get them back to the spec but now they simply refuse to sleep… I like the units and I am open to suggestion because if they will not operate properly I will return them.
