No power? No power? I have a P-133 that I tried to add a second (slave) HD to. I plugged in the power and ribbon cable and tried to start up. Heard a little noise. Very faint, can’t describe it. Turned the power of and on again, no faint noise. Waited a minute, turned the power on, heard faint noise………same as above. So I figured I fried the power supply, so I replaced the power supply and no power. No I wonder if the original was ok but something else was happening. I will get a multimeter and check both power supplies, but what else should I look for?
