Power System Checkout
To verify the symptom of the problem power on the
computer using each of the following power sources:
1. Remove the battery ASM.
2. Connect the AC Adapter and check that power is
supplied.
3. Disconnect the AC Adapter and install the charged
battery ASM; then check that power is supplied by the
battery ASM.
If you suspect a power problem, refer to the appropriate
power supply check listed below:
v “Checking the AC Adapter”
v “Checking the Operational Charging” on page 15
v “Checking the Battery ASM” on page 15
Checking the AC Adapter
You are here because the computer fails only when the AC
Adapter is used:
v If the power-on indicator does not turn on, check the
power cord of the AC Adapter for correct continuity and
installation.
v If the operational charge does not work, go to “Checking
the Operational Charging” on page 15.
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 (V dc)
1 +15.5 to +17.0
2 Ground
If the voltage is not correct, replace the AC Adapter.
