You suspect you have drained your battery

You see one or more of the following symptoms:

  • Device may be completely unresponsive with no signs of life
  • MeeGo or Maemo fail to boot up. The point of failure is random or attempts keep getting shorter
  • Battery voltage may be 3.0-3.3V (you may know how to measure this)

Your best choise for recovering is to boot Maemo 5 and let it handle recharging. How to do that depends on how MeeGo was installed into your device:

In case you have a working dualboot configuration between Maemo 5 PR1.3 and MeeGo

  • Power down, remove MeeGo SD card, connect Nokia wall charger and wait.
  • It will show amber status led until it boots to Maemo which will handle charging.

In case you have flashed the MeeGo kernel into N900, but have a working Maemo rootfs

  • You have to flash Maemo 5 kernel back to the device in order to boot Maemo and recharge.

See this page: http://wiki.maemo.org/Updating_the_tablet_firmware and search for "Flashing only the kernel from a FIASCO image"

  • If flashing seems successful continue as follows:
  • Power down, remove MeeGo SD card, connect Nokia wall charger and wait.
  • It will show amber status led until it boots to Maemo which will handle charging.
  • If flashing Maemo kernel fails, or above doesn't help, keep reading.

In case you are unable to flash Maemo kernel or do not have a working Maemo rootfs to boot into

  • You can always recharge the battery in another N900. Go to a phone store/friend/enemy near you and ask nicely if they can charge your battery for a while.
  • Recharge the battery using a phone compatible with the battery (refer to instruction manual) As always - you are doing this on your own risk.
  • Other creative ways to charge battery exists, ask help from MeeGo community.
