System Flash Codes
When errors that occur during the boot routine cannot be reported on the display or on an external monitor (if attached), the Num Lock, Caps Lock,
and Scroll Lock indicators (see Figure 1) may flash together in a pattern of lights (or flash code) that identifies the problem. For example, one
flash, followed by a second flash, and then a burst of three flashes (code 1-1-3) means that the computer was unable to read the data in nonvolatile
random-access memory (NVRAM). This information is important to the Dell support staff if you need to call for technical assistance.
The Num Lock, Caps Lock, and Scroll Lock indicators flash briefly when the computer is turned on. The flash codes, if needed, occur after the boot
routine.

partitioned as a boot device.

You probably have a bad sector or

Run the appropriate utility to check the file structure on the diskette
or hard-disk drive. If a large number of sectors are defective, back
up the data (if possible), and then reformat the diskette or hard-
disk drive.
Seek error
The operating system cannot find a
specific track on the diskette or hard-
disk drive.
If the error is on the diskette drive, try another diskette in the drive.
Shutdown failure

malfunctioning.
Run the System Set tests in the Dell Diagnostics.

immediately exit it. If the message reappears, call Dell for
technical assistance.
