Quick Solutions Checklist
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, connect the notebook to an electrical outlet using the
AC Adapter.
■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, “Battery Packs” section, on the Documentation Library CD.
