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)

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.

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.
