CPU scaling nonexistent with Inspiron 5150

[pevans_om]

I also have this problem with my Inspiron 5150 (P4 2.8GHz). 



Just a few comments.

This processor family does support CPU Scaling using Intel Speedstep
technology. Under Windows XP my processor runs between 1.6GHz and
2.8GHz depending on the demand.

My Inspiron runs a mobile Pentium 4 which is different from the Desktop
P4. I'm sure Samuels does too. Under XP I get between 3.5 and 4 hours
battery life which is comparable to a lot of the new Centrino
processors based laptops, so all in all it is not a bad Laptop
processor.



Samuel try the following I found on a different thread:


Code:
--------------------
    sudo modprobe p4-clockmod
--------------------
 



This worked for me.
