My Lumia 800 packed it in with under 7 months on the clock.  Pulled it out of my pocket, tried to bring it back from sleep, but no go.

Luckily the place I purchased it from was 1KM down the road from where I work.  I get the phone back on Tuesday apparently.

This has happened once before when I ran the battery down to zero.  The phone wouldn't recognize that it was plugged in or charging.  One of the biggest Lumia flaws if you ask me.  I know it was not that this time, as I had it on the charge all day on my computer and had only taken it off the charge an hour before this happened.  Keep in mind I had checked the battery notification too, so it isn't like it wasn't plugged in properly.

I have a feeling it was that new firmware, but I can't be sure.  I'll let everyone know what the repair company says.  Anyone else with a Lumia 8 or 900 that has done the same thing?
