A few quick questions re battery and N900: - is it possible for the N900 battery to suddenly fail ? - can the N900 boot without a battery ? (powered by charger) - would 3.46V indicate a flat battery ? - do batteries suddenly fail (following after a full discharge) Problem: My N900 is about 10months old and been working well with dual-boot Maemo & Nitdroid. I left it last night downloading a slow download from Android's Marketplace over WiFi and the N900 is now failing to start When put on charge it will pulse/vibrate, the orange LED will come on for ~30secs, then another pulse and LED will go off for ~30-seconds and keeps repeating this. The screen is grey and showing NOKIA. The power-button has no effect. With the charger removed and after the screen has blanked completely, the power-button lights up the LED & screen to white and displaying NOKIA for ~20secsnd and then off It also fails to boot in flash/recovery mode I believe this requires >50% charge (??). I've purchased a new battery and external charger, but with the holidays these will be a week before delivery, and I'd welcome any advice/suggestions. I really hope this is just a battery problem, but so sudden ? Oh! I have previously has the USB port replaced but this feels secure and it does recognise when either the PC or charger USB cable is connected. TIA -- HammY
