Usually, I can leave the battery out for 30-40 minutes, but sometimes that doesn't fix it. If that doesn't work, try this -- get a plastic bag and put your N800 in it, then put that in the freezer (with the battery in) for about 5 minutes, then in the refrigerator for a minute or so.
When you take it out, while it's still cold, plug it into the charger... the screen should turn on within a minute or so and say "Charging".

If that doesn't work, I've sometimes had to repeat the above process with the battery out of the device when I put it in the freezer/refridgerator.

I'm not sure why this works, but it seems to fix it every time for me.
The last time that I had to do this was (ironically) right before upgrading to OS2008 which was supposed to fix this problem-- after you get yours working, I'd really recommend upgrading to the latest firmware, as it seems to have fixed the problem for me.


Hope this helps somehow :)
