Hi Liam,

on one hand, as I said, I spent many hours in October trying to do 
exactly that,
and it led me nowhere. I simply cannot afford to continue on that 
specific road.
That laptop is 5 years old and something else may break any moment. 
Money-wise,
it would likely make more sense for me to buy a new laptop , than 
getting behind
with paid work to hunt BIOS problems, or pay somebody else to do the 
same.
I wanted to troubleshoot this disabled networking problem because it
is essential (see below) as much as for just learning/refreshing some 
notions.
But I cannot continue to go after it.

On the other, the laptop does NOT contain any data or software not fully 
backed up
elsewhere, and is not used for any "LOCAL" critical work. I's a spare 
machine still
very useful around here for Windows games, website administration, 
email, online
collaborative writing, testing server shell scripts on Linux... I'm 
aware there are
"issues", but as long as it does those things, why not use it?

This said, this morning I realized that I should not need for a while 
several
customizations I had done in July, so I managed to get an USB key with 
Ubuntu
16.04 and reinstalled it. That has fixed networking, so for now I'll 
keep using the machine
as said above. But I DO appreciate and thank you for your explanation on 
what
to do even on the Windows side, and happy to have learned that too.

Thanks Liam and all!
