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.
• 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.
If the power light is solid blue and the computer
is not responding — The display may not be
responding. Press the power button until the computer
turns off and then turn it back on.
If the power light is flashing blue — The
computer is in standby mode. Press a key on your
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.
