>Description:
        When shutting down the machine via poweroff / shutdown -p, it will enter
        ACPI state 5. This state though will drain the battery as if hibernated.
        Only shutting down with shutdown -h and then pushing the acpibut until
        the power supply is cut will save the battery life. I.e. one should not
        use shutdown -p with this machine.
        
>How-To-Repeat:
        On a Toshiba Portege 3440, envstat -s charge -d acpibat0 ; shutdown -hp 
now;
        wait a couple of hours; boot; envstat -s charge -d acpibat0.
        Observe the battery's lost a lot of power.
        
>Fix:
        dunno.
