power shutdown. Isolate this problem by removing one of
the devices, and use the computer under the same
condition, and see whether a power shutdown occurs. Do
this procedure for all devices to determine the cause.
Power Systems Checkout
To verify the symptom of the problem, power on the
computer using each of the following power sources.
1. Remove the battery pack and diskette drive.
2. Connect the AC Adapter and check that power is
supplied.
3. Disconnect the AC Adapter and install the charged
battery pack; then check that power is supplied by the
battery pack.
If you suspect a power problem, see the appropriate power
supply checkout in the following list:
“Checking the AC Adapter”
“Checking Operational Charging” on page 31
“Checking the Battery Pack” on page 31
“Checking the Backup Battery” on page 32
Checking the AC Adapter:
You are here
because the computer fails only when the AC Adapter is
used:
If the power problem occurs only when the port
replicator is used, replace the port replicator.
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 Operational Charging” on page 31.
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:
(16 - 10 V)
If the voltage is not within range, replace the AC Adapter.
If the voltage is within the range, do the following:
Replace the DC/DC card.
