Run CPU-Z. Windows has crappy detection of hardware elements.

one core isnt running slower than the other. Your processor is running at 798mhz but the chip is rated to run at 1.6 ghz. Run CPU-Z and see what that shows. Also your chip will downclock when not under load

Pretty sure that is showing the throttled speed and the rated speed too.

If you can get into the BIOS, disable EIST(Speedstep) and CIE. Both those features throttle your CPU when not under load, be warned your laptop will run a little bit hotter.

Centrino defines a platform technology that meets a list of compliance, it is not a CPU. That is a Core 2 Duo, not a Centrino.

The "1.6GHz" is part of the CPU name that Windows reads from, so it is listing the 1.6GHz as part of the name, and the following speed is the speed it's running at.

It's not really throttling. It's scaling it's speed back under lighter loads to save on power draw (and in the case of laptops, results in longer battery life), so do not disable it. You'll just cut into battery life and perhaps make it run warmer. It will go back to full speed when the load level demands it so there's no reason to.

I have the exact same laptop, Cover that Serial and Its Core Duo, not Core 2 If i recall correctly, also, Mine's a Core Duo at 1.9ghz, and it clocks down due to heat at times.
