Solving Problems 47
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.
• Ensure that the electrical outlet is working by testing it with another device,
such as a lamp.
• Bypass power protection devices, power strips, and power extension cables to
verify that the computer turns on.
• Ensure that the main power cable is securely connected to the system board
(see page 79).
• Ensure that the front panel cable is securely connected to the system board
(see page 79).
• If the problem persists, contact Dell (see page 107).
IF THE POWER LIGHT IS STEADY AMBER — The computer is receiving
electrical power, but an internal power problem might exist.
• Ensure that the microprocessor power cable is securely connected to the
system board (see page 79).
• If the problem persists, contact Dell (see page 107).
IF THE POWER LIGHT IS BLINKING AMBER — A device might be
malfunctioning or incorrectly installed.
• Remove and then reinstall the memory modules (see page 92).
• Remove and then reinstall any cards (see page 80).
• If the problem persists, contact Dell (see page 107).
ELIMINATE INTERFERENCE — Electrical appliances on the same circuit or
operating near the computer can cause interference. Other causes of interference
are:
•Power extension cables
• Keyboard and mouse extension cables
• Too many devices on a power strip
• Multiple power strips connected to the same electrical outlet
