30 Troubleshooting Tips
Bypass power strips, power extension cables, and other power protection
devices to verify that the computer turns on properly.
Ensure that any power strips being used are plugged into an electrical
outlet and are turned on.
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.
IF THE POWER LIGHT IS BLUE AND THE COMPUTER IS NOT RESPONDING
Ensure that the display is connected and powered on.
If the display is connected and powered on, see in your

IF THE POWER LIGHT IS BLINKING BLUE The computer is in standby mode.
Press a key on the keyboard, move the mouse, or press the power button to
resume normal operation.
ELIMINATE INTERFERENCE Some possible causes of interference are:
Power, keyboard, and mouse extension cables
Too many devices connected to the same power strip
Multiple power strips connected to the same electrical outlet
CHECK THE BATTERY STATUS LIGHT To check the battery charge, press and
release the status button on the battery charge gauge to illuminate the
charge-level lights. Each light represents approximately 20 percent of the
total battery charge. For example, if the battery has 80 percent of its charge
remaining, four of the lights are on. If no lights appear, the battery has no
charge.
