i got a problem...

a month ago, my n900 won't start up.

the battery getting flat , so i bought a new one.

but that doesn't help at all.

everytime i try to charge, or turn on, nothing happen. no changing on the light, and i didn't have nokia logo appear on it too if i press the turn on button.
the funny thing is, when i connect the charger, nothing change in illuminating light on the upper left corner, but if i'm take out the battery without unplug the charger, the light is there (yellow one).

i try to holding the u key and connect the N900 my computer via USB. and nothing happen too

i'm really don't understand what happen with my phone, because before it's dead, i was only listening to music....

i go to the nokia care, but they told me to replace the phone machine, and it cost me Rp. 1.900.000,- (if it's only Rp. 500.000,- i will pay, but the price is ridiculous)

could anybody in here can help me??

i want my n900 back to life without paying so much money.

I would try leaving the device on charge for 12 hours. If that fails then try charging the battery with an external charger caddy, can be picked up cheaply.

i tried the external charger.
i believe now my battery is full, but it's still won't start up.

If you believe you have a full battery.

Try removing the battery / SIM / uSD.
Hold the power button down with the battery removed for 10 seconds.
Reinsert battery / SIM / uSD
Close back cover
Wait for a few minutes.
Try booting the device.

If that fails try and see if you can Reflash

After that you may have a faulty uUSB port.
