working and provides information on the status:

a 10-Mbps network and the computer.

a 100-Mbps network and the computer.

a 1000-Mbps network and the computer.

a physical connection to the network.

provide status for wireless connections.
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, temporarily 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.
If the power light is solid white 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
problem persists, see the Dell Technology Guide
on the Dell Support website at support.dell.com.
