Sounds like there is some acpi-problem then. On my thinkpad it takes maybe
five seconds for it to go from -1 to an estimate. Also
hw.acpi.battery.state=0 for me equals "AC plugged in and battery full". I
have this in my .xinitrc to monitor my battery ( in a loop which then uses
xsetroot to show the info ):
case `sysctl -n hw.acpi.battery.state` in
0) batstate="AC full" ;;
1) batstate="`sysctl -n hw.acpi.battery.time` m" ;;
2) batstate="AC charing" ;;
