Overclocking a Dell Laptop?

[superblast]

I've got a Dell Inspiron laptop and noticed a peculiar thing. When I boot the system on battery power and run CPU-Z it tells me I'm running at 550 MHz (5.5 x 100 MHz). If I boot it with the system plugged into AC, CPU-Z says the processor is clocked at 700 MHz (7.0 x 100 MHz). This suggests that the chip is not multiplier locked. I'm wondering if anyone's been able to change the multiplier themselves because I'm assuming this chip will probably safely go to 850 MHz if I can just get to the settings.

What's this processor supposed to be? Is it a 550 or a 700?

Would that be anything to do with the SpeedStep technology Intel has??
When using the battery, there's not as much power, so it throttles down to 550 to preserve battery life. When you have AC power, it can run full out at the rated 700(which is what I assume you paid for, a 700?)
I dunno, I don't have a laptop, but from what I hear, the Intel laptops do this exact thing.

It's supposed to be a 700 MHz chip so I'm assuming that these new chips can use any multiplier. I'm guessing I would need to force a bios update from a 850 MHz model Inspiron though if I wanted to run it at that speed. Thanks for the info on the Speedstep technology btw.
