no charge through dumb charger
 

Hi,

I was wondering if there're any discernible explanations as to why my phone would not charge over a standard Nokia wall charger? It charges fine over a USB port. I even bought a new Nokia AC-10X charger. As an experiment, I also tried connecting my standard (and also tried it with a blackberry) cable. Both allow charging and data connection over a computer USB, but fail when I connect it to my universal charger with a USB port.

I understand certain dumb chargers won't allow charging unless a couple of the pins are shorted, but I used the same Nokia chargers.

I used 'lshal -m' and registered some output for the computer USB connection, but none whatsoever when connected straight to a power source.

I'm hoping this is more a software matter.. and if so, I have installed a couple of softwares recently, and one of the only ones that I can imagine that would cause such a problem was the h-e-n program (even then i'm very doubtful), which enables USB OTG include a VBUS 5V boost (which I did try out).

Thanks.

a shot in the dark but it could be a problem with the socket
tried another socket/in another room?

You need to short the data pins for the phone to register the dumb charger as a wall charger.
i have made a lot of usb chargers so far for my N900 and other phones

yeah, well, i tried my laptop charger on that socket and it works .. and i've tried my n900 wall charger on a couple of other sockets.. thanks for the help though :(

and dr_frost, i bought a new n900 charger.. no help, so i dont see how shorting a useful usb charger might help ..

umm sorry i misread your post.

can't help you with that problem, i also have h-e-n and all kind off charging methods though USB works, everything from homemade battery powered chargers to various wall chargers.

another shot in the dark which had helped me a while ago, unbelievably
the problem i had was that the charger WOULD connect but it wouldn't charge
i left the battery out for about an hour and put it back and it suddenly started working again

Had this problem with my nokia charger last january, never found a way around it. i've been stuck using the USB charger ever since

Re: no charge through dumb charger
 

Similar issue here, although the device believes it's charging but doesn't actually seem to draw any power.. tested with multiple chargers.

I had a similar problem, where my n900 would either not charge at all, abort charging after a while, or charge very very slowly. This was with the official Nokia charger.

From PC it charged fine.

I had a 3rd party AC to USB power adapter (from a tomtom GPS), opened that up to shorten the data pins and it has been charging my n900 just fine.

I'd suspect the Nokia charger ;)
