My daughter's lap, HP dv96408s with Vista, has been behaving erratically wrt graphics display the past few days. It would go to a black screen with no error messages displayed. Finally, on booting, it would go to a black screen-no error messages-although you could clearly hear Vista booting (the boot song) but it would sit at this black screen.
I thought the graphics card was fried or something. Then I came across info from HP's website about doing a hard reset and tried that. Miracles happened when I rebooted and voila! Vista's display, along with everything else, came back. Unfortunately, while trying to make sure the resolution was set correctly and all, and before I was able to check for driver updates, first the touchpad stopped responding (it could be due to dirt, but it was ok beforehand.) I plugged in the USB mouse, and that worked. Next, going to my Sys Admin login screen, found the keyboard wasn't responding. I requested a shutdown, to which it seemed to comply, but then the screen went black again and just hung there, not shutting down at all. I ended up doing a hard shutdown just to keep it from overheating (I checked, and it wasn't hot at all-plus it's on a fan base.)
So I'm left with wondering what it is that could be causing this. I was really happy to see that the graphics card was still working, but could it be failing anyway? Is it a driver issue? Would that keep the system from shutting down correctly, and why?
I swear, with 2 laps circling the drain here, I feel both helpless and confused.
