Now when plugged in it runs awesome. So I would try that. Also, before I did this I had the energy saver setting set to "automatic" This setting says it will set the cpu to max performance when plugged in but it I guess it really didn't. Hope it helps!

Thanks for the tip, will check this out and report back. On the surface the PB with the ATI 128MB 9700 should have the goods over the ATI 64MB 9600 in the centrino laptop.
