Hi...
I have the same problem....
I bought the N900 in USA since almost a year ago. However I have the problem since a month ago.
Original wall charger and generic charger is almost never recognized... unless i connect the charger and then turn off the phone and then the led starts to show me that the phone is being charged when phone is off....
It is also charged when I connect the charger when the phone is on, and the I reboot it....
Usb connection is always successful... however when the phone seems to start charging... the real fact is that nothing happens... I mean the led shows that phone is being charged but battery wont charge....
I have flashed maemo and emmc several times... however i cannot get rid of the problem...
Do you solve the problem???
anny suggestion...
is there hardware issue???
i'm from south america... it's almost impossible to find a official nokia support center....

I did solve the problem, I threw the N900 into oblivion and got a Samsung Galaxy S.

Well, my N900 didn't charge even if it was turned off, so I eventually got an external charger and charged my batteries with it...
Until one day, after updating to PR 1.3, I came to realize that my phone is charging again
Somehow, flashing the firmware (both emmc and firmware) did not help, but updating OTA fixed it.
I have no idea why...

Anyways, my advise for you is to flash your device - I think something from extra-devel might have messed your system up (in my case, I think it was the power-kernel).


Hmmm... well that's hardly a solution
Some people just don't like Google to know what they're doing every second, and generally take part in one of the world's largest data-mining project

It's so sad for me. I've always thought that nokia phones are the best hardware. Maybe this time I have bad luck. However I'm really carefull with my phones.

I think phones should have different ports for charging and data connectivity.... I used to have my N95, N80 and I never get this kind of charging problems....

I've always bought nokia phones, however nowadays I see great android, apple , blackberry phones. Maybe now it's time to change... until nokia releases meego phones, maybe N9.

I think my N900 has a hardware issue. Here in my country is very difficult to find spare or good technical service. So I think I must get a new phone...

I hope Meego could put nokia phones in the top of the list. It's going to be dificult to defeat android and apple mobile operative systems.

Thanks for your advice....

I might have missed a lot of the replies so pardon me if it has been said before, but why don't you buy an external charger with spare battery like this one (http://talk.maemo.org/showpost.php?p=876682&postcount=4).

In the past when I've problem with the charging socket of other phones (it happened quite frequent to me I don't know why) I'd just reply on the external charger until I switch to next phone. Don't just throw away your N900 just because of such minor issue that can be worked around.

sjgarciav, I either missed it or you didn't answer me - did you, or did you not try reflashing you phone (both firmware and emmc)?

Is this the same charger you got bundled in the box with your N900 when you bought it?

Yes... It's the original nokia charger.
