Power Problems
If the power light is off — The computer is either turned off or is not receiving power.
•Reseat the power cable into both the power connector on the computer and the electrical outlet.
•If the computer is plugged into a power strip, ensure that the power strip is plugged into an electrical outlet and that the power strip is turned on. Also bypass power protection devices, power strips, and power extension cables to verify that the computer turns
on properly.
•Ensure that the electrical outlet is working by testing it with another device, such as a lamp.
•Check the AC adapter cable connections.
If the AC adapter has a light, ensure that the light on the AC adapter is on.
Solving Problems
If the power light is solid white and the computer is not responding — The display may not be connected or powered on. Ensure that the display is properly connected and then turn it off and then back on.
If the power light is blinking white — The computer is in standby mode. Press a key on the keyboard, move the pointer using the touch pad or a connected mouse, or press the power button to resume normal operation.
If you encounter interference that hinders reception on your computer — An unwanted signal is creating interference by interrupting or blocking other signals. Some possible causes of interference are:
•Power, keyboard, and mouse extension cables.
•Too many devices connected to a power strip.
•Multiple power strips connected to the same electrical outlet.
