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 the
Dell™
Technology Guide
on your computer or at
support.dell.com
.
