n900 does not charge or connect over USB

Hi,

 

my N900 started to behave strangely few days ago. When connected to PC with USB cable, it says as usual that it is charging and after I choose Mass Storage mode it says USB connected. Well, those are all lies, I cannot connect to it and it also does not charge over USB. It does charge through wall adapter though so far. I have restarted it several times and removed battery but nothing helps. Any advise? Is my N900 USB port starting to die?

Re: n900 does not charge or connect over USB

Hi, yes I have tried to connect n900 to 3 different PCs with no luck, I have used it previously with two of them often with no charging or connection problems. I have not installed any new applications for a long time. After latest restart N900 says not charging insufficient power when I connect it to any of USB ports on dock or laptop, it still says connected to USB but PC does not recognize the connection.

Re: n900 does not charge or connect over USB

i think there is a prob with your usb cable.(not sure)

better to try a different cable..

anyway whats your firmware version? is it PR 1.3?
if not upgrade it PR1.3
(use nokia software updater)

i hope its not a hardware prob in N900.(Coz some devices got a huge prob with their micro usb port...)

Re: n900 does not charge or connect over USB

its probably a hardware problem, but since the phone is acting bad, its probably a software problem.
this could be caused by a theme, or an app or even a widget that you recently installed .

Re: n900 does not charge or connect over USB

couple things here, and it could be any or all of them.

you said that you are connecting it to a usb port on a laptop. sometimes if the laptop is low on power or not pluged in, the ampage to the usb is minimized to help offset battery drainage.

if it is a pc, it may be an older or dying usb port. be sure you are trying a usb2.0 port to ensure that it is sending enough power. usb ports are stuck at a low amp rate, which i cannot remember off the top of my head right now and am too lazy to search it for you, and this could be the reason that you are still able to charge with the travel charger.

check to see if you have installed any connection type applications. ie-advanced connection manager, bthid, bluemaemo, etc. some of those, especially the first one listed here, will make an absolute mess of your device and are for developers only. you may as well try to uninstall all of the connection applications and if that doesnt work, reflash your device.

your cable could be faulty or "cheap"

i try to use the nokia cable as much as possible, while i believe that all cables should be made the same are reletively are, there are differences in how some carry data or amprage.

Laptop is docked and dock is powered all the time. I removed Bluemaemo but it made no difference. I will try to reflash it as soon as I have time.

Re: n900 does not charge or connect over USB - I hope it is not the dreaded USB port problem

 What you are describing is very similar to what I experienced just before the micro USB port came undone from the device.  I recommend you test the cable with other devices to rule out damage.  Are you able to recharge the device using the electrical outlet power adaptor?  If not, that would be more evidence you are having a hardware problem.  You could examine the micro USB port for damage or looseness.  Good luck.

Re: n900 does not charge or connect over USB

Did you find out what was causing your problem?

If so, how did you fix it?

Cause I'm experiencing the exact same thing with mine...

 

Thanks

Re: n900 does not charge or connect over USB

Well, as a matter of fact, I did get the thing working again.. After few months I decided to reflash my n900 and if it would have not helped, send it to repair. I removed the SIM card and inserted it to other phone and then tried to connect n900 with the USB cable with my computer again.. it connected fine and started charging for my suprise. So I put SIM card back in and it has worked since with no problems.
