Hey,

I got N900 without usb-port because it became so loose and i couldnt fix it and i wont try to fix it anymore. The phone works fine though, just cant charge it without external charger.

I already got a new phone, but i'd like to use my N900 as a server computer for irssi so i need it to have it in charge all the time.

I found this from a thread where they talk about batteries and stuff
Could i open the wire of my nokia n900 charger (what goes to microusb port) and join the + and - wires straight to the battery terminals with battery on and put the resistor between GND and BSI? I haven't checked yet does it have the same output voltage than USB connection would (+5V).
