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

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 ;)
