Is the Notebook Receiving Power?
If the AC Adapter light is off and the notebook cannot be turned
on, adequate power may not be available to the notebook.
■
If the notebook is running on battery power or is connected to
an external power source other than an electrical outlet, use
the AC Adapter to connect the notebook to an electrical outlet.
■
Make sure the power cord and AC Adapter cable connections
are secure.
■
Verify that the electrical outlet is providing adequate power
by plugging another electrical device into the outlet.
When the AC Adapter light turns on, the notebook is receiving
adequate power.
✎
If the notebook turns on when connected to external power but
not when running on battery power, recharge the battery pack. For
more information about running the notebook on battery power,
see the Hardware Guide, Chapter 3, “Battery Packs,” on the
Documentation Library CD.
