Hi, the information are obtained with the power chord unplugged. I
notice that the result of "powertop" and "apci -V" are different.

ric@ricmbp:~$ acpi -V
Battery 0: Discharging, 75%, 01:04:08 remaining
Battery 0: design capacity 4851 mAh, last full capacity 3520 mAh = 72%
Adapter 0: off-line
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10
ric@ricmbp:~$ sudo powertop
PowerTOP 1.11   (C) 2007, 2008 Intel Corporation 
Power usage (ACPI estimate): 315.8W (0.1 hours)

The two results seems to be different. 
Furthermore, the battery information displayed by the power applet
sometimes are divergent from the results of the "apci -V". I mean the
battery indicator is red (about 4%) but "apci" says 66%.....

Best
