Troubleshooting
126
– 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
• If the power light is blinking blue, the computer is receiving electrical
power, but an internal power problem might exist.
• If the power light is steady amber, a device may be malfunctioning or
incorrectly installed.
– Remove and then reinstall the memory modules (see "Memory" on
page 151)
• Eliminate interference. Some possible causes of interference are:
– Power, keyboard, and mouse extension cables
– Too many devices on a power strip
– Multiple power strips connected to the same electrical outlet
