My N800 was working yesterday. Today, it refused to boot. Plugging in the charger causes it to flash its screen every 6 seconds or so; at first Nokia appears on the screen, but after a while the screen is blank when luminous. I tried reflashing. The reflash seemed to proceed normally, but failed to cure the problem. I called Nokia Support; the person I talked to suspected that the battery had died, and advised me to return the N800 to my place of purchase or mail it to the repair center in Huntsville, Alabama. Has anyone else seen these symptoms? Any useful advice? Thanks. Craig Milo Rogers
