Title:
  Battery design capacity is zero

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Seen on Ubuntu 12.10.

  I've a Lenovo G780 unit for which the battery design capacity is
  reported as zero. This is a brand new unit.

  In /sys/class/power_supply/BAT1 I can find the following information:

      POWER_SUPPLY_NAME=BAT1
      POWER_SUPPLY_STATUS=Charging
      POWER_SUPPLY_PRESENT=1
      POWER_SUPPLY_TECHNOLOGY=Unknown
      POWER_SUPPLY_CYCLE_COUNT=1491
      POWER_SUPPLY_VOLTAGE_MIN_DESIGN=1000
      POWER_SUPPLY_VOLTAGE_NOW=11820000
      POWER_SUPPLY_POWER_NOW=635500000
      POWER_SUPPLY_ENERGY_FULL_DESIGN=0
      POWER_SUPPLY_ENERGY_FULL=47520000
      POWER_SUPPLY_ENERGY_NOW=36350000
      POWER_SUPPLY_MODEL_NAME=
      POWER_SUPPLY_MANUFACTURER=Li-Ion
      POWER_SUPPLY_SERIAL_NUMBER=PABAS0241231

  At first, I thought that this was a battery issue, but when I use
  Windows based battery tools, I get good values for the 3 capacity
  values:

      design capacity
      last full charged capacity
      current capacity

  These 3 values are different in windows, so it's not that one of the
  capacity values is reused for one of the other values.

  This is a Ubuntu defect.
