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:
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.”
