CAUTION:
Before working inside your computer, read the safety information that
shipped with your computer. For additional safety best practices information, see
the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
If the power light is blue and the computer is not responding, see "Beep
Codes" on page 10.
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.
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.
– 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.
– Ensure that the main power cable and front panel cable are securely
connected to the system board (see "System Board Components" on
page 40).
If the power light is blinking amber, the computer is receiving electrical
power, but an internal power problem may exist.
