Hey there. So, my N900 has stopped working, *again*. I have no idea why, but it's not starting up at all. I can hold the power button for a day, or try to put it in update mode all I want, but it won't turn on. The only sign that the battery isn't bad is that when I connect it to my laptop, I can always see an orange light. But nothing other than that. How do I fix it?
