N900 charger hardware\software problem

my n900 is not charging,when i connecting the phone to any charger(including usb) it says "not charging" and makes Strange noises :confused:

Re: N900 charger hardware\software problem

it's really important................

Re: N900 charger hardware\software problem

By "strange noises", do you mean noises from the speakers, or from somewhere else?

My n900 also does this from time to time, I just have to reboot it occasionally for it to recognize the charger.

Are you using the wall charger that came with the phone, or a 3rd party charger? My friend's Motorola charger won't charge my n900, either-- it says "not charging" too.

Good luck!

Re: N900 charger hardware\software problem

motorola charger does 1000 mAh MAX...........

Re: N900 charger hardware\software problem

Okay, have you tried rebooting your phone?
Just tap the power button and select "power off". Wait a few seconds for the scree to turn off and the status light to go out, then press and hold the power button to turn it back on.

This is usually the easiest way to fix any problems the n900 has, since most software-related problems tend to resolve themselves with a reboot.

Re: N900 charger hardware\software problem

yes i tried that,this is not that

Re: N900 charger hardware\software problem

Also, my n900's charger (the one that came in the box) says it's 1200mAh. If you're trying to charge from the motorola charger and it's giving you the "not charging" sign, try either a different charger, or plug your n900 into a computer.

1000mAh might not be enough to charge the n900 if it's too empty.

Re: N900 charger hardware\software problem

maybe my battery was died(1 year of use)

Re: N900 charger hardware\software problem

my charger says 1200 mAh too

Re: N900 charger hardware\software problem

Nah, 1 year of use shouldn't be too big of a deal.
The only two things that have ever caused my n900 to say "not charging" both related to the charger either having insufficient power output or the charger being totally broken.

Do you have another charger, or a PC and a microusb cable around?

EDIT: okay, if your charger is the right mAh rating, can you try a PC ?

Re: N900 charger hardware\software problem

i'd connected the phone to the charger for 9 hours!!!
still don't help

Re: N900 charger hardware\software problem

Can you get on the #maemo IRC? http://wiki.maemo.org/IRC
I can help you much faster over there...

(Or if you're not comfortable with IRC, I can use Yahoo or AIM)

EDIT: Well, I'm off to dinner for now, but I'm sure someone on IRC can help you-- the community is excellent at solving problems like this.

Good luck!

Re: N900 charger hardware\software problem

Another possibility is tha the USB port has broken and is near death.

Re: N900 charger hardware\software problem

In X Terminal type:

Code:

lshal -m

Then plug the charger in, you should have an output something like this:

Code:

Start monitoring devicelist:

-------------------------------------------------

18:24:56.502: usb_device_1d6b_2_musb_hdrc property usb_device.vbus = 1 (0x1)

18:24:56.686: bme property maemo.charger.connection_status = 'connected'

18:24:56.693: bme property maemo.charger.type = 'unknown'

18:24:56.701: bme property maemo.rechargeable.positive_rate = true

18:24:57.253: bme property battery.rechargeable.is_discharging = false

18:24:57.277: bme property battery.rechargeable.is_charging = true

18:24:57.374: bme property battery.remaining_time = 7200 (0x1c20)

18:24:57.433: bme property maemo.rechargeable.charging_status = 'on'

18:24:57.528: bme property maemo.charger.type = 'wall charger'

After charging for a bit a charging status update should appear:

Code:

18:25:15.246: bme property battery.voltage.current = 3975 (0xf87)

18:25:15.289: bme property battery.reporting.current = 788 (0x314)

18:25:15.289: bme property battery.reporting.current = 788 (0x314)

I seem to have a problem with the wall charger, too.

Thanks for the command, and I do get some output, but....
...only the last two lines :

Code:

18:25:15.246: bme property battery.voltage.current = 3975 (0xf87)

18:25:15.289: bme property battery.reporting.current = 788 (0x314)

(Not exactly these values, but these terms.)

How come it reports something (almost immediately) upon plugging the charger, but does not properly recognize the charger and eventually does not charge at all?

Oh yeah, this happens to the original Nokia charger as well as to the Apple and SonyEricsson "220V-to-USB"-type chargers (which vary in their electrical output). And those chargers work with and charge their respective phones.

Currently, I can only charge via USB from a PC and would like to find a remedy to that limiting situation.

Any help or explanation is welcome.

Re: N900 charger hardware\software problem

If it charges from your PC, then the N900's not broken.
If it won't charge from your Nokia wall-charger, then that may be broken. I assume it won't charge from the other chargers because the two middle pins aren't connected to each other.

Re: N900 charger hardware\software problem

maemo5, please don't spam. Also, it helps to start requests for help in the most useful section for the subject. I'm moving this to N900.

I had problems charging my N900, it only charged via USB from a computer, no wall charger was able to charge it. EXCEPT one! An old Nokia charger which needed a USB-adapter plugged on top of it (it had that round connector)... That was strange, but soon after explained itself, somehow.

Soon after I found that this wall charger powered my N900, it would not charge anymore when it was normally plugged, the cable or connector had to be bent in some way. Likewise, charging deteriorated for the PC-USB-cable.

Nothing else helped but to take the N900 to the Nokia repair center. Sure enough, after two weeks I have a phone that I can charge again with almost any charger that fits the plug. Free repair, no questions asked. Btw, got a new IMEI during the repair process...

Re: N900 charger hardware\software problem

hi guys, since last weeks everytime I plug in charger (wall and usb) I've to plug well inside the jack otherwise my device begin to charge/disconnect charger...
also if I write using phisical keyboard (cable between my fingers) I've this problem. to recharge battery without this alternate charge/disconnect I've just to leave my n900 on some place without touch it.
Is my microusb connector breaking?
:(

Re: N900 charger hardware\software problem

Hello!

Well, it definitely sounds to be heading that way. That is how it started with my device, too. Charging got difficult and flaky, it was best to leave the device alone. In the end, I even had to bend the plug and apply pressure to make it charge.
