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.
