Actually, it doesn't go green. When I plugged in the charger the yellow light turned on, and after a while (could've been half an hour or more) the yellow light simply turned off. It never went green. The yellow light is the only sign of life on the N900, the screen never flickers on and the power button doesn't work etc. I'll be away for a few minutes, going to try a 3rd computer just for the heck of it.
