It is Norton Internet Security , which I know is heavy , but would have still imagined that this new T7100 Santa Rosa chipset of Intel could handle it easily . I was planning to replace it at the end of the free 90 days I have on it . The graphics is Intel's new integrated Mobile 965 Express Chipset with GMA X3100 adaptor . I also thought that this should be sufficient for anything except gaming . I'll set the Power High performance and see what happens . Again I would still have imagined that this notebook could handle all of this quite easily . Thanks .
