Well, Dave, if you're energetic enough to check this post of mine too, this is a very similar, but different laptop. When I told my wife you fixed the floater laptop, she rushed in with her's that she's not used for about 3 months. HP 4800, XP Windows. I fired it up and all looked fine until just after the start screen populated with icons. Then pointer/mouse pad freezes. Hard power down and a few restarts produced no better results. It has AVG, but certainly needs updating.
This machine has been used at times with external mouse. I tried that as well. Nothing. I can hit numeric key and it toggles light back-and-forth which I read is a good sign. There is some minimal access to arrow keys being useful, but not entirely.
So I guess I need to figure out how to work-around the freeze to get something going. I once used safe mode, but it's been a long time.
