Does anyonw know how to "soft reset" the N900 without removing the battery? My N900 has sometimes does not turn on after being off and charging for a night. I must remove the battery and put it back in for the N900 to turn on (holding down power button does not do the trick).

Does anyone know if there is a any "reset" button to perform the equivalent of taking the battery out and putting it back in?

Assume the N900 is off and locked up, pressing power button does nothing, only battery removal helps.

Thanks
