I'm comfortable with getting my hands dirty. I've build machines from
scratch several times and used to consider myself a 'geek' when I just
used Windows machines.
Linux makes me feel like a newbie, even though I've been running Ubuntu
and MythTV for years. I never seem to have a clue when something goes
wrong (that never happens to me in windows), but that's software.
Machines are still machines so I'm happy to operate on the PSU.
I'll check for the light.
Switches have all been checked and tried plugging into a different
socket with a different lead.
