lucky13, I'm on learning curve in DSL.
From this topic, It made me know that Power Saving in BIOS setting (Dynamic) doesn't work on DSL.
I agree with you. I will be very happy if I can run DSL longer per battery charge than SuSE or M$ Window$.

A quick and dirty way to do this, if you have a speedstep processor, is boot from USB toram and use the following:

# echo 7 > /proc/acpi/processor/CPU0/performance
# hdparm -Y /dev/hda

This will put your CPU in the slowest, lowest power state and turn off your hd. Your battery will last a long time, but some things (eg compiling drivers) will work more slowly.

There's nothing wrong with your laptop or with DSL. In your power options, you probably have it set for "always on." Intel's speedstep reduces CPU speed by half when the CPU is being underused to reduce battery consumption. That's not a bad thing, imo. You can change that if you want but you're not running at half-speed all the time and changing the setting wouldn't "fix" anything -- just drain your battery faster.

Use the most current version of DSL.

Thank you a lot! It works after changing power options

Now, the CPU is recognized as 299MHz and the computer works much faster than it used to.

Actually, I always use A/C power so I do not need to worry about the battery.
