ok...i dont think this one was posted yet...and we seem to be running "Dry"
when your n900 flashes low battery or shuts itself off. plug in the charger to give it more power!
hope that helps.
Tip Nr. 1:
How can I deactivate this feature. I have lost several calls because i had my N900 in the pocket, either sitting in the car with the N900 horizontal and the display upside down, or while getting it out of the pocket turning it by mistake with display down and hanging up instead of getting the call. This is no good feature for me. I read this complaint also in another forum (Maemo) and there was no answer to this problem.
