Hello friends, I'm using Hardy Heron 8.04.1, Linux kernel version
2.6.24-19-generic. My machine is a Dell Inspiron 1525 Laptop with 2x
Intel(R) Core(TM)2 Duo CPU T5550 @ 1.83GHz Processor, and 2GB of Ram
(I'm herewith attaching a full specs of my machine generated using the
tool HardInfo). Here goes my problem.

I'm running firefox and totem now. My System Monitor shows a  cpu usage
of 30% in both of my processors. I was running on AC power when my cpu
showed 30%. Now when i unplug the ac power, and run on battery power, my
system monitor shows both cpu usage as 60%. I did the same thing for
almost ten times and am finding the same thing. This is the most
peculiar problem which one can encounter. Please find me a solution for
this as increased cpu load in battery mode means more battery power
consumption which is not good.
