140 Troubleshooting
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 168).
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
