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?

check your battery connectors. I had similar behaviour and after thightening them up everything is fine.

Thanks, but how exactly do I do that?

take out the battery and scratch the pins with a needle and pull them if required

Thanks, but that doesn't help.I pulled them so close they were almost touching (all three of them). On connecting a charger, same as before behavior.

With nothing else to go with than that, I would say that the battery is completely flat and needs recharging. I won't insult you by asking if you've tried that but... have you perhaps tried an offline charger or another battery?

Another question: Does it respond to flasher? You don't need to actually flash anything, just try one of the query commands.

The damned thing doesn't even get into Update Mode. As for another battery, can I order and use this? http://tinyurl.com/n900bl5j The model's the same, but the phone model is something else.
PS: What's an offline charger? The one you plug into the wall outlet? Didn't try that yet. *facepalm*

EDIT: With the wall charger, it turns on for a few seconds! I get a super-dim Nokia screen, like the one on the Update Mode.
EDIT 2: The exact thing that happens is like this:
Connect charger >few seconds> Dim Nokia Screen + Orange light fades off >few seconds> Nokia screen fades off.

get a new battery

Thanks. Does the battery I linked to work in the N900?

Yes, BL-5J is what you want.
