Thanks for your quick response.
I had already done your first two steps, to no avail. So where do I get a new mainboard? I can only find used ones...
It's probably just about impossible to find a brand new board at this point - everything out there will be used or refurbished.
Notebook production runs average 6-9 months, and spares are built at the same time. Once production ends, so does parts production -- and this system being several years old, that would have been some time ago.
