The power connector (barrel type) had a bit of
oxidation on the contacts
which I tried to clean and scrape away. I got a fair amount off of it. I
never thought to check the voltage coming out on the other end of
connector, but I'll do that tonight.
If you can get to the connections at the mains adapter end of the power
cable, try soldering a piece of cable between the right points in the
adapter and the right points on the PSU board in the computer. That way
yo by[ass the power connector and possilble broken wires in the original
cable.
Assuming this is an electronic problem, I would
first test all the
electrolytics on an ESR meter. High-ESR capacitors cause the most odd
faults on SMPUSs...
I'll need to find one...
