Mike, that is just the thing. My tasks & services have all been gone through and over looked and slimmed both down. Firefox being the heaviest app running on the user level while most everything else is system. Even so, these processes are not much different than what normally runs in Vista, which brings me and some others who have helped to the boggle. Unless there is a process that has a memory leak, or using unnecessary system resources, I am at a loss. Again, this notebook was designed for Vista, not XP. But would it really make that much of a difference? Here is a screen of the processes, Pretty slimmed down , Firefox taking most of the system resources.
Peter, I have taken this unit apart and blown the fan & mobo off. I had even went and put aftermarket thermal grease on the sink because it was overheating. Even when being blown out right away, CPU is still running at 80ish C in XP and 60 C in Vista.
