There is the rub though: I need to succeed the first time or I make the 
laptop completely useless.

I've done plenty soldering in my younger years. Heck, I even soldered my 
first PC entirely from a Heatkit in '82 and it booted up on the first 
attempt. But the pinpoint accuracy required in soldering on today's 
notebooks is not comparable to that prior experience, I'm afraid. My 
eyes are also not as good and my hands are not as steady, either. I also 
looked what it would take to get to the guts of this laptop and that's 
not encouraging. So, I guess, I am stuck, but thanks for your 
suggestions nevertheless. They confirmed what I suspected was the problem.

I would hate to sell something with hidden problem.
