Re: N900 dead?
did they old charger with adapter kill it because it sends a higher voltage than the standard usb 5v?

Re: N900 dead?
I had the same happen to me. I left the phone charging overnight
connected to my laptop. I think my laptop went to suspend and in the morning the phone wouldn't show any signs of life. I didn't have an external charger so I brought the phone to a local Nokia care center and they said that if they don't spot the problem there they have to send it forward for repairing which could take from 3 to 6 weeks. :( I'm nevertheless interested in hearing if someone finds out the actual reason/solution for the problem. So please don't forget to post if you happen to succeed. :) |

the adapter is called CA-146C http://europe.nokia.com/MEDIA_BANK_1...6C_240x240.png Quote:
Now something totally different, I had some alike problem with my PSP, and i had to short-circuit my battery, it's a dangerous solution but it worked fine. But I'm not gonna try it with my battery if i don't got any background information about it |
Re: N900 dead?
2.75V is too low for the device to run on (and it can't run on power from charger), and it needs to run in order to charge..
3.2V is probably the lowest the battery can/should go.. |

I suspect that the USB connection to a PC in sleep mode is draining the battery completely (is a bug/problem I think). Connecting the AC adapter to the N900 requires the software to react (to switch to charging mode), which requires the N900 to have a bit of voltage left (is also a bug/problem I think), which it does not not have because it is fully drained. At the end I took a 5 volt AC adapter and stripped the 5 volt wires, plugged it into AC power and hold the two wires to the + and - of the battery (minus wire to the + pole, plus wire to the - pole). After a few minutes the battery had just enough power to switch to "recharging mode" after putting it back to the N900 (still connected to the AC charger). It worked for me, but no guarantees of course... Good luck... |

Maybe it was Guy Fawkes day? (insert your local pyrotechnic occasion). Just putting 5V on the cell is dangerous enough. Though the protection chip should have helped. My story: I found the n900 turned off - probably low battery. But it would not come on with the charger connected, even though the charging light glowed. Charged a while, still would not start. Eventually I took the battery out and measured 3.45V, so presumably it had indeed been charging. I put battery back and it worked. Why would I have to remove & replace battery to get it back on after running flat? |
Re: N900 dead?
Leave the phone on the charger for a considerable amount of time, try overnight. Take the battery in and out, try again. Definitely invest in an external charger, there are many available for the 5800 which uses the same battery as the N900. Sounds like the battery is completely dead and is not getting enough power to the cpu to charge properly. I wouldn't go as far and say the device is dead, just a battery issue it sounds like.
