Ive had my n900 for a while and looked after it well. The usb port is fine. I came accross this issue today, I have been using Nitdroid on it 0.0.3 wifi version and was running it for a while and the batt was a bit low., it then just died out when i was in proccess of turning it off. I can' t seem to charge it with no matter what cable, wether from pc or wall charger, taken battery, sim and sd card out but nothing. No light indicitar, its just like its dead.
Ive tried other suggestions of taking batt out and holding the power button, but that doesn't do nothing either. Also tried connecting it to the pc and holding down the U key but that got me nothing. I am at a dead end an no idea why this has happened. Someone said it may be a coincidence that it has happened now and unrelated to me installing and using Nitdroid but I dunno as I did flash a power kernel to use that and had it in r&d mode. Ive never overclocked the n900 and I didnt use the overclocking power kernel either.

please help
