Hey, dude... I know the score round here ;-)
So... no probs

even better news (4 me anyway) is that
Ive kinda sorted out my problem now...
You see, I needed to check for a loose connection at the base
of my power supply, inside the VAIO itself...
Anyway, after taking numerouse screws out, loosing them,
finding them, etc... I got pissed off and put it back together...
At no time did I get any nearer the power supply...
BUT THEN !!!
(And all on its own...)
It was working again !!!
YEAH !!!
So... its all cool...
Well, for now... anyway :-)
Laterzzz...
