Can the Notebook Not Be Turned On?
If an AC adapter light is off and the notebook cannot be turned on, adequate power might 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 AC outlet, connect the notebook to an AC outlet using the AC adapter. Make sure the power cord and AC adapter connections are secure.
■Verify that the AC outlet is providing adequate power by plugging another electrical device into the outlet.
When an AC adapter light is on, the notebook is receiving adequate AC power.
If all power and power/standby lights are on, the notebook is on. If all power and power/standby lights are off, the notebook is off.
✎If the notebook can be turned on when connected to external power but cannot be turned on when running on a battery pack, recharge the battery pack. For more information about running the notebook on battery power, refer to the Hardware and Software Guide.
