Public bug reported: acpi cannot detect my battery, so the indicator can't show me the status of it. Im using a "toshiba l640 ".I have tried many Ubuntu versions (old and new) and all of them posses the same issue.The Laptop runs without AC power supply, it means battery is able to power-up the laptop but it does it show a status. My BIOS has been updated to the very latest version and all packages are up to-date.
