Power Problems
If the power light is off — The computer is
either turned off or is not receiving power.
Reseat the power cable into 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.
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 power supply light on the
•
back of the computer is on. If the light is off
there may be a possible problem with the
power supply or the power cable.
If the problem persists, contact Dell (see
“Contacting Dell” on page 57).
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, then back on.
If the power light is solid amber —
The computer is in sleep or standby state. •
Press a key on the keyboard, move the
connected mouse, or press the power button
to resume normal operation.
There may be a problem with either the •
system board or the power supply. For
assistance, contact Dell (see “Contacting
Dell” on page 57).
