Title:
  ACPI battery information not correctly updating on Acer Aspire ZG5

Status in “acpi-support” package in Ubuntu:
  New

Bug description:
  My battery status indicator is reporting incorrect times for both
  charge and discharge. The time will fluxuate greatly across values
  much to large to be believed (5 hours to charge, 6 hours to
  discharge). The battery will also not indicate a correct charge
  percentage. Upon reboot, the information appears correct for a few
  minutes, then starts drifting to incorrect values. Attached are the
  hal-device outputs from similar bug report already on Launchpad.

  Charging
  acpitool -b
    Battery #1     : charging, 38.05%, 04:51:32

  Discharging
  acpitool -b
    Battery #1     : charged, 38.17%, 02:14:36
