Please be reminded that whenever you do troubleshooting to check the
source voltage of the power supply especially when using a dual-voltage
Automatic Voltage Regulator.
Yesterday, I serviced a CNet external dial-up modem.
The computer could not automatically detect it (plug and play). It's
good that I still have the old reliable USR external modem with me. When
I plugged it, the indicator for power won't light. I got suspicious and
when I checked where it was plugged in, it was in the 110V instead of
the 220V slot.
I transferred the plug, the modem was
detected automatically. I removed it, re-installed the CNet modem, plug
it to the right slot and it was detected automatically.
So always check power supply before you do troubleshoot. It is a timesaver.
