Hey, so yesterday I got my new Nokia Lumia 925 phone.

I upgraded it to the latest update from Nokia and followed the shops advice to let the battery run completely down first, then fully charge it.

When it was fully charged, I think unplugged it.

This morning I've woken up and the phone is completely dead. I've plugged it back into the charger just to check it's not that - and nothing.

I've tried resetting it with down-volume + camera button then power - and again nothing is happening.

Am I missing something obvious here?

Maybe it is just a battery drain, which are not uncommon on Windows Phone 8. Just keep it plugged in for a few hours, and see if it turns on.
I had a similar problem with my Lumia 710 recently. As it turned out, keeping it plugged in for 30 minutes revived the phone.

However, if this doesn't work out for you, I strongly recommend you take it to a Nokia care center.

Try the volume down + power key for 10 secs. Should power back up. You can insert a charger and it should blink if battery is dead.
