WHAT TO DO
If you are operating the system with battery power,
check that the battery pack is correctly inserted.
Attach the AC adapter to recharge the battery.
If you have the AC adapter attached, check that
the electrical outlet you are using works.
Power-saving mode may have shut off the
backlight. Press any key, Fn+F5, or use the
suspend button. The built-in LCD may not be
selected. Press Fn+F3 once or twice.
Brightness control may need adjustment. Adjust the
control.
The system entered Suspend mode due to low
battery power. Press the suspend button to resume
operation. If the system does not resume, plug in
the AC adapter or replace the battery pack, and try
pressing the suspend button again.
Use power-saving modes.
Adjust the brightness control.
Make sure the component is securely installed or
connected. Verify that the system parameter for the
I/O port configuration is set correctly in Auto Setup.
