Power Lights

CAUTION:
safety instructions shipped with your computer. For additional safety best
practices information, see the Regulatory Compliance Homepage at
www.dell.com/regulatory_compliance.
The power button light located on the front of the computer illuminates and
blinks or remains solid to indicate different states:
If the power light is blue and the computer is not responding, see "Power
Lights for Desktop Computers" on page 273.
NOTE:
On certain systems the power light is green.
If the power light is blinking blue, the computer is in standby mode. Press
a key on the keyboard, move the mouse, or press the power button to
resume normal operation.
NOTE:
On certain systems the power light is green.
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 back of
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.
Replace power protection devices, power strips, and power extension
cables with similar in known working condition 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.
Ensure that the main power cable and front panel cable are securely
connected to the system board (see the Service Manual for your
computer).
If the power light is blinking amber, the computer is receiving electrical
power, but an internal power problem might exist.
