Can only charge throw USB cable, wall charger does not work?
 

Can't charge my phone with original Nokia charger, also i tried my wife's blackberry charger, same problem-I can't charge. BUT it charging with Nokia car charger and Nokia USB cable that come with the phone. Does anybody have the same issue? I still have 2 weeks before my warranty expire. Is it phone or charger issue?

Re: Can only charge throw USB cable, wall charger does not work?
 

I was having a similar problem and after sending it in to the Nokia repair centre, thinking that my loose usb was the problem, had them sending it back to me after just upgrading the software to PR 1.3 and reflashing.

I got it back today and it is charging like a charm, the usb port is still loose, but it is charging straight away.

So, maybe try reflashing?

Re: Can only charge throw USB cable, wall charger does not work?
 

I had same trouble - wall charger stopped charging, but usb still worked. But after a few weeks I had to start jiggling the usb connector in the socket to get it to charge so I knew it was the N900 hardware and not the wall charger - took it to repair centre and recieved a replacemnt under warranty.

EDIT: The wall charger works with the replacement unit fine.

Re: Can only charge throw USB cable, wall charger does not work?
 

If the car charger works then I would say it is most likely your wall charger that is at fault.

When charging from a dumb charger the N900 expects the data pins to be shorted (i.e. connected together), not all USB chargers do this, if the Blackberry charger doesn't do that, it would explain why it doesn't work for your N900. Maybe try charging your wife's Blackberry from your N900 charger, if it does charge then you can rule out it being a problem with the charger.

Hi, I forget to say that Nokia charger charging Bkackberry!

Re: Can only charge throw USB cable, wall charger does not work?
 

If the wall charger is charging another device not the N900 then it sounds like you have a hardware problem with the N900. Even though its tempting to get by with the usb charging you could end up being unable to charge at all. As its still under warranty I would get it seen to now before its too late.

Re: Can only charge throw USB cable, wall charger does not work?
 

That is the first symptom of the dreaded loose usb port issue. Send it back to Nokia asap for replacement before you lose your warranty. It will continue to charge from pc for about 1 week then you will find you need to fiddle with it for pc to start charging. Then after another week you will find it will stop charging or connecting to pc completely.

Open X-Terminal and type:
After that connect your wall charger to your N900, wait for 30 seconds and copy paste the monitoring output to here.

Re: Can only charge throw USB cable, wall charger does not work?
 

Well it looks like your device does recognize the charger being plugged, but something is still wrong as it doesn't recognize it as a "wall charger". For example, this is how my output looks like:

08:38:47.097: bme property maemo.charger.type = 'wall charger'


Can you please run the same command, and this time connect your USB cable instead of the charger?

Re: Can only charge throw USB cable, wall charger does not work?
 

i had the same problem! but after a few days charging with USB doesn't work either! lol brought it to nokia repair centre, still waiting for my n900 (2 weeks ago)

Re: Can only charge throw USB cable, wall charger does not work?
 

Stupid question, is it the N900's Nokia charger? Me and a buddy swapped a blackberry charge one time and it would not properly charge my phone ... which was a que for me to check it and get my charger back.

Worth a look.

Re: Can only charge throw USB cable, wall charger does not work?
 

My phone has developed a similar issue lately, but I think I've found a simplified fix:

When switching from wall charger to usb or car charger, reboot the phone before starting the charge.

Know it sounds like a pain having to switch off and reboot the device every time you change charger, but it's a lot less painful than sending the phone in for repair.

/offtopic:
are they your youtube videos?

Re: Can only charge throw USB cable, wall charger does not work?
 

Is this the same charger that came with the phone?
The same cable? Try a different cable.

Try a different charger with at least the same number of Milliamp output and same voltage. It could be a bad charger or the cable.

I accidentally plugged in my Amazon Kindle charger to the N900. The little white charger really heated up and did not charge the n900. Not a wise move.

Re: Can only charge throw USB cable, wall charger does not work?
 

The battery voltage on my charger is about 4100 or so when hooked to the PC or the wall charger.
Your reading is 3784. Could this be too low from the charger?

Re: Can only charge throw USB cable, wall charger does not work?
 

Pffff I wish... I just happen to love this artist's videos and music, thats all :)

What? are you SURE this is the output when connecting the device to the computer with the USB data cable? :confused:
So how come it recognizes it as maemo.charger.type = 'wall charger'?
Are you using the original Nokia USB cable which was supplied to you with your N900? It is very important that you do, as sometimes even if a cable looks like it fits the N900 - it actually doesn't.

For example, in addition to my N900 I also own a Nokia N85, which also uses the same Nokia CA-101 micro-usb cable, but for some reason it won't work properly if connected to my N900 (the computer won't recognize the N900), and if I try to connect the micro-usb cable which I received in the box with my N900 to my N85 - the N85 won't be recognized by my computer...

This is the micro-usb cable I received in the box with my N900:

My point is - if you didn't use the N900's ORIGINAL micro-usb cable when you started the lshal -m command, please do so and then paste the output to here.

You're welcome :)

Re: Can only charge throw USB cable, wall charger does not work?
 

Went to T-Mobile today. Ask for New Nokia charger. Tried to charge, same results. Not charging. So I called Nokia and ask for repair. Will send tham tomorrow . Thanks for everybody for your Help!!!!!!!

Re: Can only charge throw USB cable, wall charger does not work?
 

That's just bizarre, USB is a standard, and to carry the USB logo the device/cable must conform to the USB standard. There is no reason why what you say should be the case. The N900 uses a standard cable, I got two micro USB cables with my Mifi and they both work fine with my N900, I guess it is possible Nokia made the N85 USB port non-standard requiring a non-standard cable, but if they did why would the cable have the same label as the N900 cable.

Re: Can only charge throw USB cable, wall charger does not work?
 

Charging on the N900 is controlled by software, I think in this case it is a software issue, so it may be solved by flashing the firmware. But bare in mind those that had a similar issue caused by a faulty USB port, if it is a faulty port you want to get it repaired while still in warranty, though if it isn't it might be that all Nokia do is reflash it with clean firmware and it is much quicker to do that yourself than send it to Nokia to do.
