• If the power button LED 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 the Service Manual at support.dell.com).
