this is the second time i experienced a delay before the "charging" comes up when i plugged the phone. to detail it more, i plugged the charger to the n900 and it gave me a delay, about 5 secs (battery on red, not drained). on the second time this occurs, more than 5 secs, and i was alarmed, that i unplugged the usb cable charger and re-plugged it, and instantly, it charged. in the next time this would happen, i will unplug the chatger from outlet (not the male usb from n900) and see. if the same occurs, i can tell that its only a bug, or my n900 is just quite slow (since i've been doing a lot with it during this Spring break).
