My N900 recently shut down because the battery ran out. I tried to charge it but it got stuck in a reboot loop. I tried a lot of things - switching R&D mode on and off, cleaning the battery contacts - and still nothing. I left it plugged in for 2 days in the hope that the hardware would charge it and now it is completely dead. The phone won't even flash the light when I turn it on. I bought a new battery (which took almost 2 weeks to arrive), and plugged it in - it went into charging mode - 8 hours later, this one is dead too. Help! Anybody have any idea how to fix this? I really need a phone (and I don't want to send it in to Nokia, it has personal information on there).

I would get an external charger and see if that helps. Cost, less than $10. Maybe you also need to reflash. Buy a few extra batteries too. See the thread here on batteries -- Scud is the best, better than Nokia and cheaper too. The same thread mentions a good charger for a bit over $5.

yes he is right get an external battery charger and see if it charges the battery also try to put your batteries in other phone if ur phone is not getting power from battery

in last go to some repair shop (not nokia) to repair it, in front of you if they can repair it on the spot! good luck

Where do I get an external charger? I tried Radio Shack, Best Buy, t-mobile store and kmart, and none of them had an external charger. I am in the US (in Pennsylvania).

i had a problem similar and the external charger solved the issue. bought one off ebay for 1 or 2 bucks shipped. i dont care if its a good one or not, it worked hehe.

So what am I looking for? All the external chargers I've seen on eBay were like $40.

Dont limit yourself to N900.
The battery is the same with Nuron 5230 and Express musci 5800

over there is 30 with free shipping.

U can try 2nd hand 5230 or 5800 express.

You probably have some other problem than just battery or charging, as batteries are delivered with more than 50% charge, which is plenty to boot and run an idle N900 for like a day...

However, right now you've probably got two empty batteries and a booting problem.

But I knew that I needed to reflash because I had problems with the audio beforehand, and I read that you shouldn't flash unless the battery is fully charged...and the phone went into a reboot loop when I tried to boot anyway...
