I have an Intel Pentium 4 Mobile processor in my laptop....can run at 1.6 ghz with its stepping technology, but always always shows running at 1.2 ghz. I only rarely see it stepped up to 1.6. How can I force this always to be top speed...is there some setting, something other than bios, where I have it set for best performance.

Personally, I would recommend AGAINST forcing a laptop CPU to always run at full speed.

Here's why.

The P4M series are designed to slow (throttle) down under light loads for 2 reasons:
Reduce heat buildup.
Reduce power consumption.

If youwish to shorten the life of your laptop, the easist way to do so would be to force the CPU to run at full speed all the time.

Look under Power Options in the Control Panel. Change the "Power schemes" option to Office/Desktop. The BIOS (like you said) should be configured properly too.

Speedstep runs when on battery, when plugged in to A/C the laptop should run at 1.6.
Intel is doing away with Speedstep eventually, too many bugs and the new 'Banias' mobile chip due out later next year needs much less power than P4. I don't think you'll shorten the life of your computer at all, many new laptops have desktop processors in them nowadays.

That did it, the power scheme setting. Had on Laptop. When I goto battery now it will slow like its supposed to, good. I just wanted my laptop to be giving juice when it had AC. :-)
