Checking the AC Adapter

You are here because the computer fails only when the AC Adapter is used:

If the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation.
If the operational charge does not work, go to 'Checking the Operational Charging'

Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable.

See the following figure:

Pin Voltage (Vdc) 1 +15 to +17.0 2 Ground

Pin	Voltage (Vdc)
1	+15 to +17.0
2	Ground

If the voltage is not correct, replace the AC Adapter.
If the voltage is within the range, do the following:

Note: An audible noise from the AC Adapter does not always indicate a defective adapter.
