How do you find the processor speed of a sony labtop?

I would like to know the processor speed of my sony labtop. I've had it for a while and cannot find the original box or anything at the moment, just have the actual labtop in my hands. Is there any way I can find the processor speed in or on the labtop itself? Thanks! 10 points best answer!|||first go to start---%26gt;right click on My Computer (Computer on Vista or 7)---%26gt; Choose Properties---%26gt; Look at the last section for Processor Speed
