Michael,

See how you get on with the specific suggestions while I do a bit of research on that laptop and the error. Yes that is the type of ID I needed.

Here's the link to the Support pages on HP for your model --

There's often useful information there as well as updates to drivers and functions but I'd try to resolve the problem first since itis being reported by Norton rather than by WIndows.
