Diagnostic Lights

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions that shipped with your computer.

Your computer has three keyboard status lights located above the keyboard. During normal operation, the keyboard status lights display the current status (on or off) of the Num Lock, Caps Lock, and Scroll Lock features. If the computer starts without error, the lights flash, and then turn off. If the computer malfunctions, however, you can use the status of the lights to help identify the problem.

NOTE: After the computer completes POST, the Num Lock light may remain on, depending on your BIOS settings. For more information on using the system setup program, see "System Setup Program" on page 111.

Diagnostic Light Codes During POST

To troubleshoot a problem with your computer, read the sequence of the keyboard status lights in order from left to right (Num Lock, Caps Lock, and then Scroll Lock). If the computer malfunctions the individual lights display a status of either On , Off , or Flashing .
