Well, not sure exactly which option worked for sure, but I'm now able to use the portable to stay online for more than 20 mins, I tried the option of downloading the software from INTEL as per the link, and then set all my 3D setting to ON in the ATI graphics setup in the bottom system tray. I also propped up the machine to allow more air circulation underneath. Graphics not great, but can move and talk. Also set the statistics option on and watched the FPS as I was using it, It never got to Green, but hovered between Yellow and Red, but it worked!
Will try some more tuning, to see if I can improve, but think the limitations of the grapics are what they are. Did try to take the settings off of low to medium, but lag became unbearable.
So a tiny step forward.
Thank you all for your responses.
