I have officially written off this laptop. I did a complete (clean) install of Windows and nothing has changed. All of the hardware drivers have been installed and updated with no solution. Thus, I suspect you are right in calling this a hardware problem. I still can't understand how, though. When I was able to get the laptop monitor to work, it continued working without any trouble until I would restart the computer. I could close the lid and open it immediately, close it and reopen in the morning. It didn't matter, the monitor would work until I restarted.
Anyway, the weird thing I am noticing is in the Display Settings dialog, the computer continues to make the external monitor the #1 monitor. I can change all of the settings and make the notebook monitor #1, the primary monitor and apply the settings, but when I restart the computer, it will flip back to #2.
I appreciate your help, and perhaps you will join me in one of my soon to come threads when I try to build a new laptop to order in the next few days!!
I would, personally:
- take the system apart and clean it good, new thermal paste etc.
- visually check out for burn or wear-n-tear inside somewhere
- replace the CMOS battery whilst I am at it.
If nothing else comes to the above, then at least you will have a heck of a tinkering (bonding) session with your notebook.
