Laptop gets heated up very early

["Goudar Vishwanathappa Manu" <manu gvm gmail com>]

Hello,
I use Compaq Presario V3133AU which has AMD Turion 64bit processor
with Nvidia C51 chipset. I run 64bit F7 and it gets heated up early.
If I keep it on without running anything also it heats up and most of
the time fan is running. Is this normal?
I get the following output when I run
$ cat /proc/acpi/processor/CPU0/info
processor id:            0
acpi id:                 0
bus mastering control:   yes
power management:        no
throttling control:      yes
limit interface:         yes

I am not understanding why power management is no.
I will be thankful for your help.
