It seems that also my USB socket is broken, it is not possible anymore to load the device. The LED is glowing "yellow" permanently when I try to connect it to the PC, also there it doesn't loads anymore or detects any device at all.

I still have a half loaded battery here which I could use to delete / backup the data on my device. I remember that there is a tool to make a full backup / image of the device on a SD card which can be loaded before Maemo booted, can anyone tell me the name?

Is there any possibility to start the N900 or load a battery by hand without a loading station for the batteries?
